Making The Common Equipment Data Connections

You must make wiring connections from the modular jack (wall jack) to the G0408 and G0816
common equipment cabinets by way of the punch-down-block, while the G1632 cabinet
provides modular jacks for the data connections.
The default data communications format is as follows:
• 7-bit data with 2 stop bits and no parity
• Baud rate of 300 baud.
Configure a data device to match this format for initial operation or reprogram the system's data
format to match those of a data device. The tables below list the system's data ports.
NOTE: The distance between a data device and the common equipment can be up to 500 feet
in a quiet electrical environment. Some sites may require shielded cable for long
runs. For longer distances, you must install limited distance modems to relay the data
communications between the common equipment and a data device.
For G0408 and G0816 cabinets, make data connections at the station connector block as follows:
Clip terminals 37-40 (data port A) and clip terminals 41-44 (data port B).
For G1632 cabinets, make data connections at special modular jacks.
