14 1.4 Safety Considerations Potential safety hazards exist unless proper precautions are observed when working with this unit. To ensure safe operation, the user must follow the information, cautions, and warnings provided in this manual as well as the warning labels placed on the unit itself High Voltage Hazards Only qualified service personnel should service the internal electronic circuitry of the vbuc. High DC voltages (300 VDC) are present in the power supply section of the amplifier. Care must be taken when working with devices that operate at this high voltage levels. It is recommended to never work on the unit or supply prime AC power to the unit while the cover is removed RF Transmission Hazards RF transmissions at high power levels may cause eyesight damage and skin burns. Prolonged exposure to high levels of RF energy has been linked to a variety of health issues. Please use the following precautions with high levels of RF power. Always terminate the RF input and output connector prior to applying prime AC input power. Never look directly into the RF output waveguide Maintain a suitable distance from the source of the transmission such that the power density is below recommended guidelines in ANSI/IEEE C95.1. The power density specified in ANSI/IEEE C is 10 mw/cm2. These requirements adhere to OSHA Standard When a safe distance is not practical, RF shielding should be used to achieve the recommended power density levels REV A vbuc Block Up Converter Manual

16 S/N: XXXX MODEL: XXXXXXXXXXXX P/N: LXXXXXX-X Figure 2-1: Outline Drawing, C-Band vbuc with optional AC Power Supply 2.2 Power Provided through IFL Cable If the vbuc is to be powered via the IFL cable, a Bias Tee is required to tap off the +48 VDC current and direct it to Port J7, the DC Input Connector. Some 24VDC vbucs can be powered via the IFL with a Bias Tee. The Bias Tee is rated for 6A and can be used with careful design. Use Paradise Datacom Bias Tee, part number L See Figure 2-2. Figure 2-2: Block Diagram, DC via IFL Cable through Bias Tee REV A vbuc Block Up Converter Manual

17 2.3 DC Cable Sizing Depending on the actual DC load of the outdoor components on the plate assembly, careful design consideration of the DC cable should be used. Typical power supply cables manufactured by Teledyne Paradise Datacom use multi-conductor cable of AWG #18. If the cable can be exposed to the environment, the cable jacket insulation should be UV resistant. The vbucs use DC/DC converters that operate as constant power devices. Though the units operate over a wide range of input voltage, the lower the input voltage becomes, the larger the current that is drawn. This in turn causes even higher voltage drops over the power supply cable. A good design rule is to ensure that the vbuc has at least 40 VDC present at the plate assembly. Thus to calculate power supply cable voltage drop use the following guideline. AWG#18 wire resistance: 6.5Ω R = = Ω 1000 ft ft. As shown in Table 2-1, the DC load of 10W Ku-Band BUC is VDC. First consider the load power dissipated by the vbuc. P load = 48 v 3.0 Amps = 144 W Then calculate the current drawn at 40VDC into the vbuc. 144W I load = = 3. 6Amps 40V With the power supply producing 48VDC and allowing for an 8VDC voltage drop across the cable, the maximum cable length can then be determined. See Figure VDC AWG #18, 6.5 Ohms/1000 ft. Power Supply BUC -VDC AWG #18, 6.5 Ohms/1000 ft. Maximum Cable Length Figure 2-3: Calculating maximum cable length vbuc Block Up Converter Manual REV A 17

18 The total cable resistance accounting for both the source and return wire is then. R= 2 * = Ohms/ft. The maximum cable resistance that can be tolerated and result in an 8V drop is then. 8 v 3. 6 A = Ω The maximum power supply cable length can then be determined by the following Ω. 013 = 171 ft REV A vbuc Block Up Converter Manual

19 Section 3: Remote Monitor and Control 3.0 Introduction Teledyne Paradise Datacom s Universal Monitor and Control Software is the next generation software utility that provides M&C functionality for the Teledyne Paradise Datacom line of Satcom Earth Station products. All operating functions can be controlled and monitored via the M&C interface. Functions that can be monitored include RF output power, attenuation, temperature and internal voltages. The interface can also be used to adjust the network address, startup state, fault handling and thresholds, as well as other parameters. The Teledyne Paradise Datacom Universal Monitor and Control Software is included on the CD shipped with the unit, and is also available for free download from the Downloads page of the web site, Section 4 details the protocol used for Serial or Ethernet communication with the vbuc. 3.1 Connecting to the vbuc There are a variety of methods of communicating with the vbuc, including via serial communication, Ethernet or FSK Connect via Serial A 2-wire RS485 communication connection is available on the vbuc s J4 M&C port for remote monitor and control. This is a half-duplex connection that requires the user to tie together both the RX+/TX+ and RX-/TX- lines on the PC side of the link. A wiring diagram is provided in Figure 3-1, with the pin-outs described in Table 3-1. Figure 3-1: Wiring Diagram, Serial Communication Cable vbuc Block Up Converter Manual REV A 19

20 Notes: Table 3-1: Serial Communication (RS485-2-wire) J4 Pin DB9 Pin Note U 2 RS485- U 3 RS485- R 1 RS485+ R 4 RS485+ L 5 Ground Jumper J4 Pin J to J4 Pin K to enable output. Jumper J4 Pin S to J4 Pin M to force serial override. Communication links using RS485 are typically good for up to 4,000 ft., but it must be noted that a termination resistor of 120 Ohms must be used on both ends of the link if distances exceed 100 ft. By default, the vbuc will be shipped in IPNET Mode requiring the user to use a Quick Start Cable to force the unit into Serial Mode. A Serial Quick Start Cable, part number L , may have been shipped with your vbuc. Please refer to the Appendix for more information on the Serial Quick Start Cable. The Serial Quick Start Cable can be used at any time to place the vbuc into a known state under Serial Mode. Once the vbuc is in Serial Mode, the default baud rate will be set to This is configurable and can be later changed using the Universal M&C Software. Make sure the PC s COM port is configured to 9600 baud, 8 Data bits, No Parity, 1 Stop bit, and No Flow Control. Install the Teledyne Paradise Datacom Universal M&C software from the supplied CD onto a PC running Windows XP. See the Appendix for instructions for PCs running Windows Vista. Terminate the RF input and output of the vbuc. If connected to a modem that is equipped with FSK, ensure FSK is turned off. Connect the Quick Start Cable to Port J4 of the vbuc. Connect the other end of the Quick Start Cable to the PC s RS485 port. Configure the PC s COM port properties as shown below. To access the COM port properties, go to Control Panel System Hardware tab Device Manager Explode the Ports category Figure 3-2: COM Properties right-click on the COM port to be configured and select Properties.

21 Connect the DB9 connector of the serial communication cable to a computer. Install and launch the Teledyne Paradise Datacom Universal M&C Software. Follow the instructions for connecting a vbuc over serial communications. See Section Protocol Auto-detect The vbuc serial M&C supports both Paradise vbuc Protocol (see Section 4.2) and the Paradise Legacy protocol (also known as VSAT BUC Protocol; see the Appendix, Drawing ). When communication begins, the unit will determine which protocol is being used and will establish a link. Keep in mind that this auto-detection may result in an initial lost packet when communication begins. Once a connection is established, the device will continue to use the determined protocol until the power is cycled Connect via IPNET or HTTP The Ethernet Interface provided on the J4 M&C Port allows control of the vbuc through an IPNET Interface (UDP encapsulated Normal Serial Protocol - Section 4.4.1) or HTTP Web Interface (Section 4.4.1). A wiring diagram of the required cable is shown in Figure 3-2, with the pin-outs described in Table 3-2. Notes: Table 3-2: Ethernet Communication (Cat5 Crossover) J4 Pin Note RJ45 Pin H TX- 6 G TX+ 3 C RX- 2 A RX+ 1 Jumper J4 Pin J to J4 Pin K to enable output. Do not untwist more cable than necessary; performance may be degraded when long lengths of cable are untwisted. By default, the vbuc will be shipped in IPNET Mode. If the unit has been previously put into Serial Mode, an Ethernet Quick Start Cable will be needed to place the vbuc into IPNET Mode. An Ethernet Quick Start Cable, part number L , may have been shipped with your unit. See Figure 3-3.

Follow the Universal M&C instructions for connecting a vbuc over Ethernet communications. See Section 3.2. Alternatively, the vbuc M&C can be controlled using a web browser. To do this, configure the PC s TCP/IP properties as described above and connect the RJ45 connector of the Ethernet communications cable to the network port of a computer. Follow the instructions on Web-based Monitor and Control found in Section REV A vbuc Block Up Converter Manual

23 3.1.3 Connect via SNMP There are no Quick Start Cables to enable SNMP communication with the vbuc. To put the vbuc into SNMP Mode, first establish an Ethernet connection, using the instructions in the previous sections to do so. Launch the Teledyne Paradise Datacom Universal M&C Software (See Section 3.2 for details). Once connected to the device, go to the Settings tab and select SNMP under the Communications Interface pull-down menu. If not previously done, configure the IP Settings under the IP Setup tab to match the network settings. After all the settings are configured, cycle the power on the vbuc to put the device into SNMP Mode. Note: Make sure the Ethernet Quick Start Cable is not connected to the vbuc when the power is cycled. The connection will put the vbuc into IPNET Mode with the default IP settings. Connect the RJ45 connector of the Ethernet communications cable to the network port of a computer. Follow the instructions on SNMP operation of the vbuc in Section Connect via FSK The FSK input must be diplexed onto the coaxial L-Band input via the Type N(f) connector at J1. Communicating with the vbuc via FSK defaults to Paradise Datacom s legacy protocol. See the Appendix for the VSAT BUC Protocol (201410). There are no Quick Start Cables to enable FSK communication. Simply apply a FSK signal to the vbuc and the unit will automatically switch from serial RS485 or Ethernet communication to FSK. Upon disconnect of FSK, the previous communication will resume. 3.2 Using the Universal M&C Software Connect a PC running the Teledyne Paradise Datacom Universal M&C to the vbuc using the instructions detailed in Section 3.1. Launch the Universal M&C software Universal M&C for Serial or Ethernet Connections From the Action menu, select Add Unit vbuc. See Figure 3-5.

33 3.4 SNMP Interface SNMP-based management was initially targeted for TCP/IP routers and hosts. However, the SNMP-based management approach is inherently generic so that it can be used to manage many types of systems. This approach has become increasingly popular for remote management and control solutions for various SSPA systems. The MIB is available for download from the Downloads section of the Teledyne Paradise Datacom web site Configuring vbuc unit to work with SNMP protocol 1. Set up the unit IP address. Use the Universal M&C to connect to the vbuc unit. Go to IP Setup tab and set the following parameters. 2. Set up the unit gateway address. 3. Set up the unit subnet mask. 4. Set up the unit Community Set and Get strings. 5. Set up the unit interface to SNMP. Go to the Settings tab under Communication Interface. Make sure the serial and Ethernet override pins are not grounded. Restart the unit by cycling power. 6. SNMP protocol is now set and ready to be used Connecting to a MIB browser For a MIB browser application example, we will be using the freeware browser GetIf, version There are many other browsers available for download from 1.

35 3.5 Remote Control Control Outputs - Summary Alarms The hardware behind the form C relay is a single pole, double throw relay. Under normal operation (no alarms) the relays are in an energized state. When a fault occurs or the unit is powered off, the relays are in a de-energized state. The relay contacts are capable of handling a maximum of 30 1A. The form C relay is shown schematically in Figure The form C relay contact outputs are listed in Table 1-1. Closed on Fault Closed on Fault Common Common Open on Fault Open on Fault Relay Energized Relay de-energized Control Inputs - TX Inhibit The External Mute input is a closure to ground with pull up resistors. To trigger a remote input command, the input should be pulled to ground. Pulling this input to ground will disable the external mute Control Input - Serial Override The serial override input is a closure to ground with pull up resistor. To trigger a remote input command, the input should be pulled to ground. The input does not need to be held to ground continuously but it is acceptable to do so. The input only need be pulled low for a minimum of 100 msec on vbuc power-up. Pulling this input to ground will put the vbuc into Serial RS485 Mode with a default baud rate of Control Input - Ethernet Override Figure 3-18: Form C Relay The Ethernet override input is a closure to ground with pull up resistor. To trigger a remote input command, the input should be pulled to ground. The input does not need to be held to ground continuously but it is acceptable to do so. The input only need be pulled low for a minimum of 100 msec on vbuc power-up.

37 Section 4: Remote Control Protocol 4.0 Overview A system, which includes a vbuc, can be managed from a remote computer over a variety of remote control interfaces (see Figure 4-1). Remote control interface stack 10Base-T IP Interface SNMP HTTP Web UDP Serial Interface Protocol: 1. Normal RS485 Alarm Contact vbuc unit Figure 4-1: vbuc Remote Control Interface Stack The M&C port on the vbuc unit provides access to a simple form of remote control. The Serial interface supports 2-wire RS485 standards. The control protocol supports the Normal serial protocol as detailed in Section 4.2. Serial protocol format is set at no parity, 8 bit with 1 stop bit. Baud rate is selectable through the M&C, but defaults to 9600 baud. The Ethernet interface provides the ability to control the system through: IPNet interface (UDP encapsulated Normal serial protocol Section 4.6.2); SNMP V1 (Section 4.6.3) or HTTP Web interface (Section 4.6.4). The Ethernet interface is fixed to the 10Base-T standard. Normally, straight-through Cat5 cable is used to connect the unit to a network hub, and crossover Cat5 is used to connect directly to a computer s Ethernet port. vbuc Block Up Converter Manual REV A 37

38 4.1 Serial Communication Protocol This section describes the basic serial communication protocol between the vbuc and a host computer. Serial port settings must be configured for 8 bit data at no parity, with 1 stop bit. The unit will only respond to properly formatted protocol packets. The basic communication packet is shown in Figure 4-2. It consists of a Header, Data, and Trailer sub-packet. HEADER (4 bytes) Header Packet DATA (6-32 bytes) TRAILER (1 byte) Figure 4-2: Basic Communication Packet The Header packet is divided into three sub-packets which are the Frame Sync, Destination Address, and Source Address packets, as shown in Figure 4-3. HEADER (4 bytes) DATA (6-32 bytes) TRAILER (1 byte) Frame Sync (2 bytes) 0xAA55 Destination Address (1 byte) Source Address (1 byte) Figure 4-3: Header Sub-Packet Frame Sync Word The Frame Sync word is a two byte field that marks the beginning of a packet. This value is always 0xAA55. This field provides a means of designating a specific packet from others that may exist on the same network. It also provides a mechanism for a node to synchronize to a known point of transmission Destination Address The destination address field specifies the node for which the packet is intended. It may be an individual or broadcast address. The broadcast address is 0xAA. This is used when a packet of information is intended for several nodes on the network. The broadcast address can be used in a single device connection when the host needs to determine the address of the unit. The unit will reply with its unique address REV A vbuc Block Up Converter Manual

39 Source Address The source address specifies the address of the node that is sending the packet. All unique addresses, except the broadcast address, are equal and can be assigned to individual units. The host computer must also have a unique network address Data Packet The data sub-packet is comprised of six to 32 bytes of information. It is further divided into seven fields as shown in Figure 4-4. The first 6 fields comprise the command preamble while the last field is the actual data. HEADER (4 bytes) DATA (6-32 bytes) TRAILER (1 byte) COMMAND PREAMBLE DATA FIELD Protocol ID 1 Byte Request ID 1 Byte Command 1 Byte Data Tag 1 Byte Error Status / Data Address 1 Byte Data Length 1 Byte Command Data Sub Structure 0-26 Bytes Protocol ID Figure 4-4: Data Sub-Packet This field provides backward compatibility with older generation equipment protocol. It should normally be set to zero. This field allows the unit to auto-detect other firmware versions Request ID This is an application specific field. The unit will echo this byte back in the response frame without change. This byte serves as a request tracking feature Command The vbuc protocol is a table based protocol. It allows the user to view and modify data tables located on the controlled device. Throughout the remainder of this description, sender will refer to the host PC, and receiver will refer to the vbuc unit. Sender and receiver are limited to two commands and two command responses. The Get Request command issued by a command sender allows monitoring of existing conditions and parameters on the receiver. The Get Request frame should not have any bytes in the Data Filed and be no longer than 11 bytes. vbuc Block Up Converter Manual REV A 39

40 The Response frame from the receiver will contain a Get Response designator in the Command field. If the receiver does not detect any errors in the Get Request frame, the requested data will be attached to the response frame. The length of the Get Response frame varies by the amount of attached data bytes. It may contain 11+N bytes where N is the amount of requested data bytes from a particular table, specified in the Data Length field. The Set Request command allows the sender to actively change parameters for the receiver s internal configuration. The Set Request frame must contain a number of bytes in the Data Field as specified in the Data length field. The frame size must be 11+N bytes, where N is the length of the attached data structure. The receiver will respond with a frame where the command field will be set to a Set Response designator. The frame length is equal to the Request frame. The byte value for each command is given in Table 4-1. Table 4-1: Command Byte Values Command Name Command Byte Value Set Request 0 Get Request 1 Set Response 2 Get Response REV A vbuc Block Up Converter Manual

41 Data Tag The data tag specifies the type of internal resource or information needed to be accessed on the vbuc. The data associated with certain tags is read only. Therefore only the Get command byte would be associated with these data tags. The data tag byte values are given in Table 4-2. Tag Name System Settings Tag System Thresholds Tag System Conditions Tag ADC Channels Access Tag Data Tag Byte Value Table 4-2: Data Tag Byte Values Minimum valid length of the Data Field 0 1 Byte 1 2 Bytes 3 1 Byte 4 2 Bytes Description This tag allows accessing various system settings on remote unit. Host access status: Full Read/Write access. Settings can be modified at any time. Some of the settings may require hardware reset of the remote unit. This tag allows access to the critical unit thresholds. Host access status: Tag have read only status. This tag allows access to the unit s internal conditions flags, such as fault status or current system status. Host access status: Read only. This type of the data can not be set or modified remotely. This tag allows access to the unit s internal Analog to Digital converter. Host access status: Read only. This type of the data cannot be set or modified remotely. Reserved 6 1 Byte This tag is reserved Reserved 2 N/A This tag is reserved. Reserved 5 N/A This tag is reserved for factory use only vbuc Block Up Converter Manual REV A 41

42 Error Status / Data Address This byte is a tag extension byte and specifies the first data element of the tagged data. If the Data Length is more then 1 byte, then all subsequent data fields must be accessed starting from the specified address. For example if the requestor wants to access the unit s unique network address, it should set data tag 0 (System settings tag) and data address 8 (see System Settings Details table). If the following Data Length field is more than 1, then all subsequent Settings will be accessed after the Unique Network Address. When the Response Frame Data Address is omitted, this byte position is replaced with the Error Status fields. The various error codes are given in Table 4-3. Note that the Request and Response frames are different. Table 4-3: Error Status Byte Values Error Code name Byte Value Possible Cause No Errors 0 Normal Condition, no errors detected Data Frame Too Big 1 Specified Data length is to big for respondent buffer to accept No Such Data 2 Specified Data Address is out off bounds for this tag data Bad Value 3 Specified value not suitable for this particular data type Read Only 4 Originator tried to set a value which has read only status Bad Checksum 5 Trailer checksum not matched to calculated checksum Unrecognizable error Data Length This byte contains different information for Request and Response frames. In a Request frame, it specifies the number of data bytes that are to be accessed starting from the first byte of the value specified in the Data Address byte. That byte must not exceed the maximum data bytes for a particular tag. The maximum data length for the Settings tag is 26 bytes. The maximum data length for the System Threshold tag is 6 bytes Data Field Error presented in originator frame, but respondent failed to recognize it. All data aborted. The actual data contained in the packet must be placed in this field. The Get Request type of command must not contain any Data Field. Any Get Request will be rejected if any data is present in the Data Field. Generally, the Bad Checksum error code will be added to the response from the unit if the word size of the information is 16-bits or 2-bytes. Each data word is placed in the frame with its least significant byte first. All data with length of 2 bytes must be represented as integer type with maximum value range from to (-32767) REV A vbuc Block Up Converter Manual

43 4.2.3 Trailer Packet Frame Check The trailer component contains only one (1) byte called the Frame Check Sequence, shown in Figure 4-5. HEADER (4 bytes) DATA (6-32 bytes) TRAILER (1 byte) Frame Check Checksum (1 byte) This field provides a checksum during packet transmission. This value is computed as a function of the content of the destination address, source address and all Command Data Substructure bytes. In general, the sender formats a message frame, calculates the check sequence, appends it to the frame, then transmits the packet. Upon receipt, the destination node recalculates the check sequence and compares it to the check sequence embedded in the frame. If the check sequences are the same, the data was transmitted without error. Otherwise an error has occurred and some form of recovery should take place. In this case the unit will return a packet with the Bad Checksum error code set. Checksums are generated by summing the value of each byte in the packet while ignoring any carry bits. A simple algorithm is given as: Chksum=0 FOR byte_index=0 TO byte_index=packet_len-1 Chksum=(chksum+BYTE[byte_index]) MOD 256 NEXT byte_index 4.3 Timing issues Figure 4-5: Trailer Sub-Packet There is no maximum specification on the inter-character spacing in messages. Bytes in messages to units may be spaced as far apart as you wish. The unit will respond as soon as it has collected enough bytes to determine the message. Generally, there will be no spacing between characters in replies generated by units. The maximum length of the packet sent to the unit node should not exceed 64 bytes, including checksum and frame sync bytes. Inter-message spacing, must be provided for good data transmission. The minimum spacing should be 100 ms. This time is required for the controller to detect a Line Cleared condition with half duplex communications. Maximum controller respond time is 200 ms. vbuc Block Up Converter Manual REV A 43

49 4.4 Ethernet Interface The vbuc supports several IP network protocols to provide a full featured remote M&C interface over an Ethernet LAN. IPNet protocol redirection of standard Paradise Datacom LLC serial protocol over UDP transport layer protocol. This protocol is fully supported in Paradise Datacom s Universal M&C software. SNMPv1 protocol - protocol intended for integration into large corporate NMS architectures. In order to utilize either of the protocols listed above, the relevant interface option has to be turned on. Refer to Section (Setting IPNet interface) and Section (Configuring vbuc unit to work with SNMP protocol) for details. Of course, standard IP level functions such as ICMP Ping and ARP are supported as well. There is currently no support for dynamic IP settings, all IP parameters IPNet Interface General Concept Satcom system integrators are recognizing the benefits of an Ethernet IP interface. These benefits include: Unsurpassed system integration capabilities; Widely available and inexpensive set of support equipment (network cable; network hubs); Ability to control equipment over Internet; Ease of use Implementation of the raw Ethernet interface is not practical due to the limitations it places on M&C capabilities by the range of a particular LAN. It is more practical to use an Ethernet interface in conjunction with the standard OSI (Open System Interconnect) model to carry a stack of other protocols. In an OSI layered stack, an Ethernet interface can be represented as a Data Link layer. All upper layers are resolved through a set of IP protocols. In order to keep data bandwidth as low as possible (which is important when M&C functions are provided through a low-bandwidth service channel) the IP/UDP protocol set is used as the Network/Transport layer protocol on Teledyne Paradise Datacom units. UDP (User Datagram Protocol) was chosen over TCP (Transmission Control Protocol) because it is connectionless; that is, no end-to-end connection is made between the unit and controlling workstation when datagrams (packets) are exchanged. vbuc Block Up Converter Manual REV A 49

50 Teledyne Paradise Datacom provides a Windows TM -based control application to establish UDP-based Ethernet communication with units. The control application manages the exchange of datagrams to ensure error-free communication. An attractive benefit of UDP is that it requires low overhead resulting in minimal impact to network performance. The control application sends a UDP request to the unit and waits for response. The length of time the control application waits depends on how it is configured. If the timeout is reached and the control application has not heard back from the agent, it assumes the packet was lost and retransmits the request. The number of the retransmissions is user configurable. The Teledyne Paradise Datacom Ethernet IP interface can use UDP ports from 0 to for sending and receiving. The receiving port needs to be specified through the front panel menu. For sending, it will use the port from which the UDP request originated. Of course, it is up to the user to select an appropriate pair of ports that are not conflicting with standard IP services. Teledyne Paradise Datacom recommends usage of ports 1038 and These ports are still not assigned to any known application. As an application layer protocol (which actually carries meaningful data), the standard Paradise Datacom serial protocol was selected. This protocol proves to be extremely flexible and efficient. It is also media independent and can be easily wrapped into another protocol data frame. An example of the UDP frame with encapsulated Teledyne Paradise Datacom protocol frame is shown on Figure 4-6.

The software package can be download from company's web site, SNMPv1 A vbuc unit supports the most popular SNMPv1 format (SMIv1, RFC1155), SNMP Get, SNMP Get Next and SNMP Set commands. SNMP Traps are currently unsupported. In order to utilize SNMP protocol, the user has to enable this feature via remote serial protocol. SNMP uses the UDP fixed port 161 for sending and receiving requests. The definition of managed objects is described in the Teledyne Paradise Datacom MIB.

59 Section 5: Redundant Operation 5.0 Redundant System Concepts The vbuc is capable of operating in a variety of redundant system configurations, including 1:1 with input splitting, 1:1 with input switching, 1:2 with the addition of a reference combiner assembly, or as part of a 1:1 transceiver system. The vbuc has a built-in 1:1 redundancy controller, allowing it to be used in 1:1 redundant transmit systems without a separate external controller. When used in a 1:2 redundant system, a separate controller, the RCP2-1200, is required. When used in a transceiver system, a RCPD-1100-LX controller is needed. The two most common forms of 1:1 redundant system are shown in Figure 5-1 and Figure 5-2. Figure 5-1 shows a standard 1:1 system in which the L-Band input is transmitted through a transfer switch along with the output. Using this configuration the standby unit carries no traffic and simply is terminated by a 50 ohm resistive load at its input and by a waveguide termination at its output. COAX AMP 1 WAVEGUIDE L-BAND INPUT RF OUTPUT AMP 2 Figure 5-1: Standard 1:1 Redundant System with input (coaxial) switch and output (waveguide) switch With the system configured as in Figure 7-2, the L-Band input is passed through a microwave splitter. Care must be taken when selecting the splitter for an L-Band input system. The splitter must be a wide band design capable of passing the 10 MHz or 50 MHz reference signal along with the 950 MHz to 1825 MHz traffic input. The reference frequency power level must be at least -10 dbm into each unit.

60 5.1 vbuc in 1:1 Redundancy The vbuc is ideally suited for a self-contained and cost effective 1:1 redundant system. Each unit has a built-in 1:1 redundant controller. The controller is activated via computer command from the Teledyne Paradise Datacom Universal M&C application. The vbuc may be purchased as a redundant system or upgraded in the field from a single thread unit to a 1:1 redundant system Hardware Setup The hardware setup for a vbuc 1:1 Redundant System is very simple and involves the addition of a single cable along with a redundancy switch. A schematic diagram of the redundancy setup is shown in Figure 5-3. COAX AMP 1 WAVEGUIDE J5 - MS3112E12-10S L-BAND INPUT SPLITTER REDUNDANCY CABLE RF OUTPUT J5 - MS3112E12-10S AMP 2 Figure 5-3: 1:1 Redundant System with 1:1 Cable Installed The Link section of the cable is a simple (3) conductor crossover cable that allows the system to pass command and control between units. The Switch section of the cable is a Tee configuration and connects between each unit and the redundancy switch. The Redundancy Switch is a -48 VDC type or a -24 VDC if using 24V input voltage. Therefore the controller in each vbuc is capable of supplying +48 VDC to the common voltage input. Either controller may then provide a (sink) return to engage either position 1 or position 2 of the redundancy switch. Care must be observed when connecting this cable to the units. The cable end labeled A1 must be connected to the unit whose output is connected to Port 3 of the waveguide switch. Likewise the cable end labeled A2 must be connected to the unit whose output is connected to Port 1 of the waveguide switch. This is for proper identification purposes of the Redundancy Control Firmware used by each vbuc REV A vbuc Block Up Converter Manual

61 5.1.2 Software Setup To instruct the vbuc to operate in redundancy it is necessary to temporarily connect it to a PC running the Teledyne Paradise Datacom Monitor and Control Software to set up the redundant configuration. There are three basic modes of Redundant System communication. 1. Stand-Alone 1:1 Redundant System - No Computer Control 2. PC Control using RS485 and Paradise M&C Software 3. PC Control using Ethernet and Paradise M&C Software Stand-Alone 1:1 Redundant System As method 1 implies, it is possible to have a 1:1 system operate with no PC monitor and control. Initially, however, it is necessary to connect each vbuc up to a PC to configure it for redundant operation. Figure 5-4 shows the redundant system with each unit enabled to use Ethernet communication to a PC. Every vbuc is shipped from the factory with a Quick Start cable that can be used for this purpose. If the vbucs are purchased as a 1:1 Redundant System, this Software Setup procedure will have been set at the factory and it is not necessary to repeat this process.

62 Each unit can be configured for redundancy by the Teledyne Paradise Datacom Universal M&C software that ships with each unit. Using the Quick-Start cable, connect each unit individually to the PC and run the M&C program. Select the Settings tab from the main form. The Settings window will appear as shown in Figure 5-5. Figure 5-5: Universal M&C Settings Window 1. Operation Mode: Each unit s Operation Mode must be set to 1:1 Redundant Mode 2. Choose a Hierarchical Address for each unit. Unit 1 means this vbuc will use the switch position 1 as its On Line state position. Unit 2 will then use switch position Redundant Startup State: The unit which is desired to be on line should be set On Line. The other unit should be set as Standby. All settings are valid as soon as the operator sets them on the Settings window. The unit s redundant operation can be verified by monitoring the RF Switch Fault indicator on the Status window as shown in Figure 5-6. Figure 5-6: RF Switch Fault Indicator REV A vbuc Block Up Converter Manual

63 The Standby unit can set to a Cold Standby condition. In this mode, the vbuc will be muted automatically. Cold standby mode has to be selected through a serial control interface (For details, see Table 4-11, data address 20). If the Standby unit is switched to the On Line state, it will automatically un-mute and transmit traffic. If the operator attempts to mute the On Line unit, a warning message will be displayed You are about to mute the On Line unit. Proceed with Mute? Similarly, connect the second unit to the computer and perform the 1:1 selections on the Settings window. Just as with the first unit, make sure that the System mode is set to 1:1 redundant. Select a hierarchical address, Unit 1 or Unit 2 and a startup state. The vbucs may then be disconnected from the computer as the units microcontrollers are now programmed for 1:1 redundancy control. It is not necessary to run the Windows based M&C software with the redundant system. The M&C software is only a convenience for remote monitoring and control of the redundant system. The following sections detail the operation of the M&C software in 1:1 redundant system operation PC Control using RS485 and Paradise M&C Software In applications requiring remote monitor and control of the redundant system, the Teledyne Paradise Datacom Universal M&C program has a control panel that can be used for this purpose. To enable the 1:1 system to operate with the remote control software, first configure each unit for 1:1 redundant operation as previously described in the Stand-Alone 1:1 Redundant System section. The RS485 link can typically be run up to 4000 ft. (1200 m) lengths. A good quality twisted pair cable should be used along with proper line terminations. There are no parallel end terminations in the unit s RS-485 interface. Any required cable terminations have to be added externally. Only half duplex RS-485 communication is supported. As in the stand-alone redundant system of Section , each vbuc must be programmed for Redundant System operation by using the M&C program. Additionally, when networking, each unit s address must be set before they can communicate on the RS-485 network. Both of these steps should be performed together as part of the initial system setup. To specify an address for an unit refer to the Settings window. If the unit already has a network address it will be displayed under the current address window. Repeat this step for both units and they will be ready to operate as a 1:1 Redundant System with RS-485 network monitor and control. vbuc Block Up Converter Manual REV A 63

64 After starting the M&C program, select Action Add Unit vbuc. The Add New vbuc window will appear as shown in Figure 5-7. From this screen choose the COM port and baud rate. The factory default baud rate is Select the first vbuc address. After the COM port has been selected the Operation window will be displayed. At this point if the SSPA is connected to a power source and turned on, the vbuc will begin communicating with the M&C program and its operating parameters will be displayed. Go back to the Add New vbuc window and select the Figure 5-7: Add vbuc correct address for the second unit. Its operation window will appear on the M&C program display. If either of the units is not communicating with the M&C Operation screen, debug the system to find the problem. Check the RS-485 connection from each amplifier to the appropriate COM port of the PC. Once reliable communication has been established between each unit and the computer, the Redundancy Control Panel can be displayed. From the M&C program s main window, choose Action Add Unit Internal Redundant System 1:1 vbuc System. The Redundant Control Panel window will then be displayed as in Figure 5-8. Figure 5-8: Redundant Control Panel Window REV A vbuc Block Up Converter Manual

65 Note that once the Redundant Control Panel is enabled, the Main Menu on the M&C program changes. The Control Panel must be configured by selecting Set Redundancy System and assigning Unit 1 and Unit 2. Either vbuc may be designated as Unit 1 or Unit 2. Each unit is identified by its ID number. The ID number is a fixed number and cannot be changed. It is a unique encoded value determined by the particular unit s model number and serial number. If the ID number is forgotten, refer to the System Watcher window. This window continuously displays which unit, by ID number, is connected to each specific COM port. From the Control Panel display all typical 1:1 system functions can be monitored and controlled. A particular unit can be put on line be selecting the command button for either unit. The online unit will be indicated by the Online notation. The standby unit will be listed as such as shown in Figure 5-8 (Unit 1). A particular redundant configuration can be saved by going to the File menu and selecting Save Configuration. Thus if the program is terminated and then restarted, it will immediately boot up with the Redundancy Control Panel display. Each individual unit s characteristics can still be monitored and controlled from its respective Operation window. If the user attempts to Mute an on-line unit, a warning window will pop-up asking if this is a valid request :2 Redundant Systems The vbuc can also be configured in 1:2 Redundant Systems. The major difference being that the converter s internal controller can not be used for system control. Instead a separate RCP Redundant System controller is used to provide system control. The controller can be remotely located from the converters up to 500 ft.

66 5.3 1:2 Redundant Systems with L Band Input The 1:2 Redundant System with L Band Input can be configured with internal 10 MHz reference oscillators or configured for use with an external reference source. Systems configured with internal 10 MHz reference are straightforward extensions of the basic 1:2 architecture. Because the 10 MHz reference is integral to the converter there is no possibility of an interruption of the 10 MHz during switchover. Furthermore the standby unit always has 10 MHz reference and will not be faulted. Such a system is shown in Figure vbuc 1 L-BAND INPUT POL 1 RF OUT POL 1 STANDBY vbuc 2 L-BAND INPUT POL 2 RF OUT POL 2 vbuc 3 ALARM INPUTS RCP SWITCH DRIVE Figure 5-10: Block Diagram, 1:2 Redundant System, Internal 10 MHz Reference A special case of the 1:2 Redundant System exists when an external reference is required of the system. With an external 10 MHz reference input on each polarity input to the system, the standby unit will not receive a reference signal and therefore would be in a faulted condition. In this state, the redundant controller will not allow the standby unit to come on line if a failure occurs with Unit 1 or Unit 3.

TO STANDBY ALARM INPUTS RCP SWITCH DRIVE Figure 5-12: Block Diagram, Switchover Interrupts 10 MHz Signal At first it may be thought that an external reference signal could be injected into the normally terminated port of the input switches. While in a normal operating state with all three vbucs operational this would work fine. However in the event of a failure of one of the on-line units, the external reference would also be interrupted to the standby unit, as shown in Figure Due to the quick determination of a unit fault, the controller will interpret a fault on the standby unit and reliable switchover can not be guaranteed. To overcome the problems that result from interruption of the external reference, it is imperative that the reference be injected in the system after the waveguide switches. One technique could be to install a multiplexer on the input of each unit that would allow the injection of the external reference. In this case a separate external reference line would have to be run to the system and a three way splitter could distribute the reference to each amplifier. The standard Teledyne Paradise Datacom configuration overcomes this issue by using a Reference Combiner assembly. See Figure The Reference Combiner assembly couples a sample of the external reference from each of the two polarity inputs. It will then supply the standby unit with the reference from either of the two inputs. The reference combiner will arbitrate and decide which reference signal to supply to the standby unit. It will not supply both external reference sources to the standby unit. This allows all three units to be in a normal operating (non faulted) condition and the RCP controller can operate the system in normal 1:2 redundancy. This eliminates the need for a separate external reference going to the system as the external reference normally exists on each L-Band cable. vbuc Block Up Converter Manual REV A 67

Should Unit 1 or Unit 3 fault, the RCP will automatically switch to the stand-by Unit 2. However, when this occurs, this interrupts the external reference to the faulted vbuc, which results in a constant BUC fault on that thread. In order to return Unit 2 to the stand-by state, the user will need to clear the fault, switch to manual mode on the RCP and then select Unit 2 as stand-by. Table 5-1 gives a step-by-step guide to returning Unit 2 to stand-by status.

69 5.4 1:1 Redundant Transceiver System Teledyne Paradise Datacom can configure a complete transceiver system utilizing a vbuc redundant system, an LNB redundant system and a RCPD-1100-LX-EXT system controller. Figure 5-14 shows a typical block diagram of a transceiver system. Figure 5-14: Block Diagram, 1:1 Redundant Transceiver System with RCPD Hardware Setup RCPD-1100-LX-EXT Dual Redundant Controller is an indoor rack-mountable unit that fits into a standard EIA 19 inch equipment rack. The RCPD-1100 is used to control the RF switches for both the vbuc plate assembly and the LNB plate assembly of the transceiver system, so a single RF thread is always active. Teledyne Paradise Datacom supplies the Switch/BUC Alarm cable, which links between the controller and the vbuc plate assembly, and the LNB switch cable, which links between the vbuc plate assembly and the LNB plate assembly. The customer must supply the TX and RX IFL cables that link the indoor and outdoor equipment. The RCPD-1100 acts as a hub between the indoor and the outdoor components of the VSAT Transceiver System. The RCPD-1100 monitors the alarms from the Block Up Converter plate assembly and the Low Noise Block Down Converter plate assembly and controls the RX/TX switches for each sub-system. vbuc Block Up Converter Manual REV A 69

70 A external 10 MHz reference signal is passed through the controller an on to the BUC Plate Assembly and LNB Plate Assembly. The controller is fitted with an RF switch in the receive path, which terminates the receive signal of the standby LNB, thus avoiding adding any additional noise to the RX signal path. By definition of Dual Redundancy using an RCPD-1100 controller, the RX and TX switches are essentially ganged and move together. For independent switching of the RX and TX switches, the system should be configured with two (2) RCP controllers. The redundant vbuc plate comes fully assembled and consists of two transmit chains, an RF switch, an RF load and all of the interconnect waveguide assemblies with a waveguide output flange to meet your specific frequency band. The vbuc s operating functions such as Phase Lock, RF output power, attenuation, temperature and internal voltages are controlled and monitored by the RCPD-1100 via the M&C interface. The redundant LNB assembly comes fully assembled and consists of two LNBs, an RF switch, a close out plate, and interconnecting waveguide assemblies to meet your specific frequency band. The LNBs are powered via the controller at +15VDC, and the frequency stability is maintained by either an internal reference or externally via the controller. For full, automatic redundancy switching, Teledyne Paradise Datacom modifies the OEM LNBs to add fault detection alarm circuitry that is monitored by the RCPD-1100 and reports a fault based on changes in the modified LNB s bias current. Table 5-2 shows the typical OEM LNBs and their performance specifications.

83 Appendix B: Proper 10/100 Base-T Ethernet Cable Wiring This section briefly describes the basic theory related to the physical layer of 10/100Bas-T networking, as well as proper wiring techniques. There are several classifications of cable used for twisted-pair networks. Recommended cable for all new installations is Category 5 (or CAT 5). CAT 5 cable has four twisted pairs of wire for a total of eight individually insulated wires. Each pair is color coded with one wire having a solid color (blue, orange, green, or brown) twisted around a second wire with a white background and a stripe of the same color. The solid colors may have a white stripe in some cables. Cable colors are commonly described using the background color followed by the color of the stripe; e.g., whiteorange is a cable with a white background and an orange stripe. The straight through and crossover patch cables are terminated with CAT 5 RJ-45 modular plugs. RJ-45 plugs are similar to those you'll see on the end of your telephone cable except they have eight versus four or six contacts on the end of the plug and they are about twice as big. Make sure they are rated for CAT 5 wiring. (RJ means "Registered Jack"). A special Modular Plug Crimping Tool (such as that shown in Figure B-1) is needed for proper wiring. Figure B-1: Modular Plug Crimping Tool The 10BASE-T and 100BASE-TX Ethernets consist of two transmission lines. Each transmission line is a pair of twisted wires. One pair receives data signals and the other pair transmits data signals. A balanced line driver or transmitter is at one end of one of these lines and a line receiver is at the other end. A simplified schematic for one of these lines and its transmitter and receiver is shown in Figure B-2. Figure B-2: Transmission Line vbuc Block Up Converter Manual REV A 83

84 The main concern is the transient magnetic fields which surrounds the wires and the magnetic fields generated externally by the other transmission lines in the cable, other network cables, electric motors, fluorescent lights, telephone and electric lines, lightning, etc. This is known as noise. Magnetic fields induce their own pulses in a transmission line, which may literally bury the Ethernet pulses. The twisted-pair Ethernet employs two principle means for combating noise. The first is the use of balanced transmitters and receivers. A signal pulse actually consists of two simultaneous pulses relative to ground: a negative pulse on one line and a positive pulse on the other. The receiver detects the total difference between these two pulses. Since a pulse of noise (shown in red in the diagram) usually produces pulses of the same polarity on both lines one pulse is essentially canceled by out the other at the receiver. In addition, the magnetic field surrounding one wire from a signal pulse is a mirror of the one on the other wire. At a very short distance from the two wires, the magnetic fields are opposite and have a tendency to cancel the effect of each other. This reduces the line's impact on the other pair of wires and the rest of the world. The second and the primary means of reducing cross-talk between the pairs in the cable, is the double helix configuration produced by twisting the wires together. This configuration produces symmetrical (identical) noise signals in each wire. Ideally, their difference, as detected at the receiver, is zero. In actuality, it is much reduced. Pin-out diagrams of the two types of UTP Ethernet cables are shown in Figure B-3. Figure B-3: Ethernet Cable Pin-Outs Note that the TX (transmitter) pins are connected to corresponding RX (receiver) pins, plus to plus and minus to minus. Use a crossover cable to connect units with identical interfaces. If you use a straight-through cable, one of the two units must, in effect, perform the crossover function. Two wire color-code standards apply: EIA/TIA 568A and EIA/TIA 568B. The codes are commonly depicted with RJ-45 jacks as shown in Figure B-4. If we apply the 568A color code and show all eight wires, our pin-out looks like Figure B-5. Note that pins 4, 5, 7, and 8 and the blue and brown pairs are not used in either standard. Quite contrary to what you may read elsewhere, these pins and wires are not used or required to implement 100BASE-TX duplexing REV A vbuc Block Up Converter Manual
