7 MULTIDROP COMMUNICATIONS ADAPTER OCT 1995 SECTION 1 INTRODUCTION 1.0 INTRODUCTION The Multidrop Communications Adaptor (MCA) links SolarFlow Plus units in a network that shares a common radio, modem, or other serial device. A separate MCA module is attached to each SolarFlow Plus unit in the network and to the device shared by the SolarFlow Plus units. The MCA modules are linked by a proprietary network interface. The network interface is designed for low power, intrinsicallly safe operation in electrically hostile environments. An MCA network can include as many as four SolarFlow Plus units and one shared device. WARNING: Underwriters Laboratories (UL) approval of the MCA as an intrinsically safe device specifies that no communications device other than the HHDT may share a serial port with the MCA and maintain intrinsic safety approval. Specifically, the MCA may not be used with a radio interface, a modem interface, or similar devices that share a serial port. The MCA module is suitable for operation with SolarFlow Plus Models 2460 and The SolarFlow Plus unit or shared device communicates with the MCA attached to it through an RS-232 compatible serial port. The MCA converts the RS-232 signals to and from network levels. The SolarFlow Plus unit and shared device communicate full duplex over the network established by the MCA at rates up to 1200 baud. The network can accommodate cables up to 1000 feet in length between SolarFlow Plus units and the shared device. SECTION 1 1-1

9 MULTIDROP COMMUNICATIONS ADAPTER OCT 1995 SECTION 2 COMMUNICATIONS INTERFACE 2.0 COMMUNICATIONS INTERFACE A SolarFlow Plus/MCA network can include as many as four SolarFlow Plus units and one shared device. Each of the SolarFlow Plus units and the shared device must have an individual Multidrop Communications Adaptor (MCA) connected to it. The network interconnects each individual MCA. 2.1 MCA/HOST COMMUNICATIONS INTERFACE Either a SolarFlow Plus unit or shared device is designated the host. If a SolarFlow Plus unit is the host, the unit communicates with the MCA attached to it through the same serial channel provided for Hand Held Data Terminal (HHDT) communications. When a HHDT cable is connected to a SolarFlow Plus unit, the MCA releases the serial port to the HHDT and communications between the SolarFlow Plus unit and the shared network device are interrupted. However communications between the shared device and the other SolarFlow Plus units in the network are not affected. Communication signals between a SolarFlow Plus unit (or shared device) and the MCA are protected against electrical transients MCA/Host Communications Protocol RS-232 compatible communications protocol is used for data transmission between an MCA and the host SolarFlow Plus (or shared device). The host protocol has the following characteristics: Signal levels: Mark (1) exceeds -3.0 volts (V) (nominally -5V) Space (0) exceeds 3.0V (nominally 5V) SECTION 2 2-1

10 OCT 1995 MULTIDROP COMMUNICATIONS ADAPTER Maximum cable length between an MCA and an associated SolarFlow Plus unit (or shared device) is 50 feet. Full duplex Maximum Baud rate: 1200 Defined signals: a. RS-232 signals: GND CTS RXD RTS TXD Power supply and signal return from SolarFlow Plus Clear to send input from SolarFlow Plus or shared device Receive data input from SolarFlow Plus or shared device Request-to-Send output to SolarFlow Plus or shared device Transmit data output to SolarFlow Plus or shared device b. Non RS-232 signals: HHDT PWR DO Input, which indicates that the HHDT cable is connected to the SolarFlow Plus Input power for the host side of the isolated interface 1000-ohm resistor-to-ground output that indicates to SolarFlow Plus that a device is connected MCA/Host Interconnection Cables Cables for connecting the MCA to host units (SolarFlow Plus units or shared device) must have the following characteristics when the MCA is not mounted in the same enclosure as the host unit. - Eight conductor with overall shield - Length: maximum of 50 feet - Capacitance (conductor-to-conductor or conductor-to-shield): 0.05uF maximum - Inductance: 10uH maximum (0.2uH/Foot) - Size: 20 American Wire Gauge (AWG) minimum, 18 AWG maximum - Voltage rating: 600V 2-2 COMMUNICATIONS INTERFACE

11 MULTIDROP COMMUNICATIONS ADAPTER OCT NETWORK INTERCONNECTION Individual MCA modules are connected to each SolarFlow Plus unit and to the shared network device. A network can accommodate up to four SolarFlow Plus units and one shared device (for a maximum of five MCA modules) Network Communications Protocol The network protocol has the following characteristics: Maximum total cable length in the network is 1000 feet. Defined signals: NRET NRTS NVMID NTXD NPWR NCTS NRXD SHIELD Network power supply and signal return input Network Request-to-Send output Reference voltage equal to half the network power supply voltage Network Transmit-Data output Network power input Network Clear-to-Send input Network Receive-Data input from SolarFlow Plus or shared device Cable shield connection to local earth ground Full duplex Maximum Baud rate: 1200 SECTION 2 2-3

12 OCT 1995 MULTIDROP COMMUNICATIONS ADAPTER Network Interconnection Cables Network interconnection cables are furnished by the user and must have the following characteristics. - Six twisted pairs (12-conductor with overall shield) - Length: 1000 feet (maximum total of all drops) - Capacitance (conductor-to-conductor or conductor-to-shield: 0.05uF maximum - Inductance: 200uH maximum (0.2uH/Foot) - Size: 20 AWG minimum, 18 AWG maximum - Voltage rating: 600V 2-4 COMMUNICATIONS INTERFACE

13 MULTIDROP COMMUNICATIONS ADAPTER OCT ELECTRICAL POWER SECTION 3 ELECTRICAL POWER The Multidrop Communications Adaptor (MCA) is designed with two separate electrical power/ground systems: the host system and the network system. Except for one host/mca unit, which supplies power to the network system, all host and network power/ground systems are isolated. Because the systems are isolated, MCA modules can be connected to host units regardless of ground differences among the various sites. This prevents network communication errors caused by ground currents. All power connections are isolated against transient voltages. 3.1 HOST POWER SYSTEM Host-Supplied Power In normal installations, each MCA host power system receives electrical power from its host unit and has a common ground with the host unit through the host/mca interface. As noted above, all host and network power/ground systems are isolated except for the host/mca unit that supplies power to the network system. The network system is described in paragraph 3.2. SECTION 3 3-1

14 OCT 1995 MULTIDROP COMMUNICATIONS ADAPTER Isolated Power Supply An MCA isolated power supply (IPS) (Daniel part number ) is available for installations where suitable power for the MCA host power system is not available from the host device. The IPS connects to Jack J2 on the MCA printed circuit assembly (PCA) and converts network power to the isolated MCA host power system Host System Power Characteristics Power for individual MCA modules is supplied by the SolarFlow Plus unit (or the shared device) to which the MCA is connected. The host power system characteristics are provided below. Source impedance: Input voltage: Quiescent current: Active current: 10 ohms maximum 9 volts minimum 15 volts maximum Typically 0.3mA at 80 o F (1mA maximum) (CTS low, NCTS high) Typically 10mA, 12mA maximum (CTS high, NCTS low, TXD and RXD active at 1200 baud) 3-2 ELECTRICAL POWER

15 MULTIDROP COMMUNICATIONS ADAPTER OCT NETWORK POWER SYSTEM MCA Configuration Plug Network power is supplied from one of the SolarFlow Plus units through an MCA configuration plug (Daniel part number ), which is installed in an MCA associated with one of the SolarFlow Plus units. The configuration plug is installed in only one MCA in the system. The configuration plug connects the host and network power systems and provides power and the ground reference to the MCA network. Once connected, the network interfaces of all MCA modules in the system draw power from the battery of that SolarFlow Plus unit and are grounded through that SolarFlow Plus unit Primary Slave MCA The MCA module fitted with the configuration plug is designated the primary slave. Any MCA in the system can serve as the primary slave (including the shared device). Another primary slave can be selected by moving the configuration plug to another unit Network Power Distribution Network power and ground (NPWR and NRET) pass through a wire pair of the network cable and provide power and ground reference for the MCA network transmitters and receivers. Network ground is also paired with each of the network control signals (NRTS and NCTS). An extra wire carries power (NPWR) in order to reduce resistance due to long cable runs. The network cable shields are connected to earth ground at each MCA. SECTION 3 3-3

16 OCT 1995 MULTIDROP COMMUNICATIONS ADAPTER Network System Power Characteristics The network system power characteristics are provided as follows. Maximum configuration is for four MCA-equipped SolarFlow Plus units and a master shared device using an MCA isolated power supply. The recommended maximum duty cycle for the MCA network is 10 percent (or 2.4 hours of network communication activity per day) to avoid an excessive drain on the battery of the primary slave SolarFlow Plus unit. Source impedance: Input voltage: Quiescent current: Active current: 10 ohms maximum (SolarFlow Plus battery current limit plus cable resistance) 9 volts minimum 15 volts maximum Typically 12mA at 80 o F, 16mA maximum (CTS low, NCTS high) Typically 43mA at 80 o F, 60mA maximum (CTS high, NCTS low, TXD and RXD active at 1200 baud) 3-4 ELECTRICAL POWER
