3 1.0 Scope This manual contains operation and installation information for the Telemetrics Serial Control Transfer Switch, Part No The unit is rack mounted and provides switching capability for the Telemetrics indoor and weatherproof robotic camera systems. 2.0 Introduction The TM-STS serial control transfer switch extends the capability of Telemetrics control panels and serial receivers. The unit allows multiple control panels to share receivers. This provides for an increased flexibility in robotics camera control design. The switch also provides a port lock and a port lockout feature. The unit is based around a modular card design. These cards convert the incoming data stream to the specified transmission protocol. This allows the user to change the transmission protocol. The TM-STS accepts six cards, with two serial ports per card. There are two versions of each card available, control panel and receiver cards. The two versions facilitate cabling to the devices using one to one cables. 1

It is a single rack height unit. The front of the unit has a power switch and a ready indicator. When the Power Switch is in the up position, the unit is on. The switch will glow red to indicate there is AC power. The Ready Indicator LED shows that the unit successfully powered up. The light behaves erratically when the unit has a failure. 1 AC Power Switch 2 Ready Indicator LED Front View Figure 1 The rear of the unit has twelve ports. Each port is a 9 D-sub male connector.

6 5.0 Operation The serial switch acts as a transparent device between the control panels and receivers during standard communication. The TM-STS will intercept its commands from the data stream and act upon them. The port initiating the command will receive a success or failure response. Communication can be established between any of the twelve ports. There are three functions to establish a link between ports: switch port, switch port (lock), and switch port (unlock). The switch port command establishes a link between the source (initiator) port and the destination port. If the destination port is already linked, it will be disconnected and then linked to the initiator. The disconnected port will be notified of the disconnect. A port can be prevented from being disconnected by using the switch port (lock) command. If a port tries to establish a link to a locked port, it will receive a failure response. The switch port (unlock) command will unlock the port. A lockout port (un-lockout port) command is also available. This command allows a port to disconnect another port and prevent it from communicating to the serial switch. Each serial switch can be addressable via an internal dip switch. This allows multiple switches to be controlled from one source. One of the outputs from the TM-STS will be connected to another TM-STS input. (Note: Linking multiple units together may degrade the performance of the receivers.) 4

7 6.0 System Setup The TM-STS is designed to work with a variety of Telemetrics control panels and receivers. Standard receivers (CP-RMR-S, PT-LP, and PT-HP-S) may be used with the serial switch without modifications. The CP-RMQ-3A and TM-CPS need to be configured to access the serial switch. Configuration of the control panels is performed at the factory. Customers who need to configure their panels should contact the factory for instructions. Sample System Diagram Figure 3 5

8 7.0 Expansion Cards The TM-STS is shipped from the factory equipped with the amount of cards needed to satisfy the current system configuration. Expansion cards can be added when a system is expanded. This allows flexibility in choosing the transmission protocol and card configuration based on all the system components. When ordering a card, specify the transmission protocol and card configuration. Along with the card you will receive an integrated circuit to be placed in the unit. To install additional cards, follow the procedure below: 1. Turn the unit off and remove it from the rack cabinet. 2. Remove the top cover of the unit. 3. Remove PC Board Place the integrated circuit provided in the next available spot on PC Board Place the serial card in the next available slot in the unit. 6. Secure the board with the two screws placed towards the rear panel. 7. Attach the screw lock kits to the 9D connectors from the outside of the unit. 8. Replace PC Board 52388, making sure all the serial cards are plugged in completely. 9. Replace the top cover. 10. Replace the unit in the rack cabinet. 6

9 APPENDIX Protocol Overview The TM-STS operates as a transparent link between control panels and receivers except for serial switch commands. The unit will determine a serial switch command based on the following format (all commands are in ASCII.): \ {UNIT ID} {PORT#} {CMD} {CHKSUM}<cr> Switch Command: \ Unit ID: 0-255, Identifies the switch ID (Unit ID is set by internal DIP switch) Port #: 1-12, Port on the switch to act upon CMD: 0-255, Action performed on the port Table 1: Switch Commands CMD# Name Description 0 Switch Port Normal connection from source to destination {port #} 1 Switch Port (lock) Locks source to {port #} (and connects) 2 Switch Port (unlock) Unlocks source to {port #} (does not disconnect) 3 Lockout Port Lockout {port #}, prevents port from communicating 4 Un-lockout Port Removes lockout from port {port #} 7

10 Chksum: {UNIT ID}+{PORT#}+{CMD}+{CHKSUM} = 0 If the checksum is not correct, the string will be transmitted to the recipient. Otherwise, the command is processed. Return codes will be sent to the ports depending on the serial switch events. The return code format is shown below. Source refers to the port initiating the command (where applicable). Destination refers to the {port #} in the switch command. All commands are in ASCII. Table 2: Return Codes Return Event CMD Description Code \0 Disconnect 0,1,3 A Disconnect event will be sent to the disconnected port. \1 Source Locked 0,1,2,3,4 Notifies the source that it is locked out. Out \2 Unlock Fail 2 Notifies the source that Unlock (cmd#2) has failed. \3 Destination Locked Out 0,1,2 Notifies the source that the destination is locked out. \4 Locked out 3 Notifies the destination that it has been locked out. \5 Port Locked 0,1,2,3 Notifies the source that the destination port is locked. Connection made to the source prior to the command request is broken. \6 Lockout Off 4 Notifies the destination that a lock out has been removed. \7 CMD Error 0,1,2,3,4 Notifies the source of a command error. \8 Successful CMD 0,1,2,3,4 Notifies the source of successful completion of command. Example: Switch to Port 3 \ <CR> 8
