Introduction The SiteGate-232 is part of the Liebert SiteScan gateway family and provides communications between a workstation and a control module network (CMnet) consisting of fewer than 50 modules. The SiteGate-232 provides two EIA-232 Console Ports for connecting a workstation and/or a modem. The console ports are switch selectable for baud rates up to 38.4k bps. Communication between the SiteGate-232 and the CMnet is provided through a EIA-485 port.
Battery: Seven-year lithium battery provides a minimum of 10,000 hours of data retention during power outages. Fault Detection: Hardware watchdog timer. Software Requirements: One LGM module driver as FB #15. Workstation software must be SiteScan for Windows v2.5b or later, Alert 1.1a or later, and FB Link v2.7 or later. Protection: ESD protection on Console Port 1. Voltage, current, and ESD protection on Incoming Power, CMnet, and Console Port 2. Hardware Accessories: Keypad display.
segment. A segment is defined as the network of modules between main nodes. Main nodes can be represented by a gateway module, or a repeater (part no. REPOPT). A repeater can be used to end one segment and begin another, all on the same CMnet. It is recommended that only a dedicated, 22AWG to 18AWG twisted pair copper wire be used for CMnet (EIA-485) wiring. Wire sizes smaller than 22 gauge or wires that are not twisted may cause intermittent communication problems.
Power Wiring CAUTION: The SiteGate-232 modules are Class 2 devices (less than 30 VAC). Take appropriate isolation measures when mounting a SiteGate-232 module in a control panel where Class 1 devices or wiring are present. NOTE: Whenever possible, terminate and verify power and communication to all modules before terminating any inputs and outputs. 1. Terminate AC power at the wiring source (usually a circuit breaker or other AC source). 2. Apply power to the transformer. 3.
Addressing, Baud Rates, and Console Settings The SiteGate-232 module's address is factory-set as control module #1 and cannot be changed. NOTE: The CMnet Baud Rate jumper (see Figure 1 for location) is only used to configure the CMnet for 156k bps. If the CMnet Baud Rate jumper is set to 156k, the CMnet Baud DIP switch is ignored. The CMnet communication speed and baud rates for the SiteGate-232's console ports are configured using an 8-position DIP switch.
Procedure 1. Turn the SiteGate-232's power switch OFF. 2. Set the module's baud rates and console port settings using the 8-position dip switch (see Figure 1 for switch location). 3. Turn the SiteGate-232's power switch ON. Communication Wiring CMnet Wiring NOTE: Only one SiteGate-232 may exist on a CMnet. NOTE: The EIA-232 connection can be 50 ft. (15.24 m) maximum. 1. Turn the SiteGate-232's power switch OFF. 2. Check the network communication wiring for shorts and grounds. 3.
The "SETGCM" Command The "SETGCM" command initializes the SiteGate-232 with system parameters including Maxnet, the workstation telephone number from the SiteScan connections page (set only for the port(s) which are connected when this command is issued), and the system's line number and 3-letter system name. The "SETGCM" command is required whenever one of the following events occur: • The SiteGate-232 module is replaced or reformatted. • A new module is added to the network.
Cables Several cables, which vary depending upon the communication requirements, are available. The following is a description and wiring configuration of each cable (the arrows indicate direction of data flow). Cable Diagrams for Console Port #1 ATAD The ATAD cable connects a 9-pin EIA-232 port to a 25-pin Hayes or compatible modem.

Common Problems Modem connected to the SiteGate-232 will not answer. Make sure the TR light on the modem is ON; if it is OFF check the modem cables. Verify connection and baud rate with the SiteGate-232. Modem connect to SiteGate-232 will not dial out. Make sure the modem installed on this port is set to "yes" in the LGM Parameter page under Console Port # and a valid phone number has been set using SETGCM or by manually entering a phone number. WRU Failure.
LEDs LED Identification The SiteGate-232's LEDs are as follows (see Figure 11): Power - indicates when power is on. Run - blinks when the processor is running. Error - lights when an error is detected. CMnet Receive - lights when SiteGate-232 receives data from the CMnet. CMnet Transmit - lights when SiteGate-232 transmits data over the CMnet. Console 2 Receive (RX) - lights when Console 2 port receives data. Console 2 Transmit (TX) - lights when Console 2 port transmits data.
LED Power-up Sequence During power-up, the module goes through an initialization and self test sequence. Proper module power-up can be verified by observing the LEDs as follows: 1. The Run and Error LEDs turn on and begin blinking. 2. The Error LED will then turn off. 3. The Run LED will continue blinking. If the module is not responding and the LEDs do not appear to be going through the appropriate initialization, call Technical Support for assistance.

If not connected, and with no alarms pending delivery, reset modem every 5:00 (mm:ss). Note: the minimum value for this is 5:00. If connected, but no activity has been detected for 20:00 (mm:ss), hang up and reset modem. After dialing, wait 2:00 (mm:ss) for connection before hanging up. After unsuccessful alarm delivery, wait 5:00 (mm:ss) before trying again. Escape (+++) guard time 1000 msec. Post hangup delay 1000 msec. Reset time (DTR low) 1000 msec. Post DTR high delay 500 msec.
Output character pacing? If set to YES, this parameter reduces CMnet transmission speed by 50%. This may be necessary when operating at 38.4k baud with older modules on the same CMnet. Delay before sending all replies (20 msec minimum) = 20 msec: The time in milliseconds to wait before replying to CMnet commands. This is necessary to allow the sender time to shut off its transmitter and prepare to receive the reply. If the reply comes too quickly, it may be missed. Interpacket delay.......
Modem Control Parameters Modem Reset: This is a user definable parameter that sends a reset string to the modem. Dial Prefix: This parameter sets the dial prefix used for dialing out alarms. Phone Number: This parameter sets the number to be dialed out for alarms. Use This Number? NO: If "YES", the phone number above will be used for dialing out to deliver alarms. If "NO", the phone number on the workstation will be used for dialing out to deliver alarms.

LGM Module Driver Status This is the overall module status. Function Block Type: This the Module Driver's three-character filename. Name: This is the name referring to the space or equipment used. Line: The telephone line number used by the Function Block. LG: Gateway module number used by the Function Block. CM: Control Module number used by the Function Block. FB: Function Block number used by the Function Block.
Module Halted: All GFB related tasks have stopped. This can only happen if there have been 3 or more frequent System Errors. System Errors are errors that are severe enough to cause the module to reset. The module can still partially communicate on the CMnet when in this Halted state, but color updates and LAN I/O requests will cease causing the gateway to declare this module “dead”. (System Errors are logged and time stamped on the Modstat screen).
Module time and date: Shows the current module date and time. Time since last reset: The amount of time that has elapsed since the last module reset. CMnet Communication lost: If "YES", this module has detected that it is alone on this CMnet. CMnet address: The module’s current CMnet node address. This should be set to 1 for the SiteGate232. CMnet baud rate 9600: The module’s current CMnet baud rate. Module Driver Memory Free: Unused module driver memory. Used: Memory used by the module driver.
