RELAY UNIT CONNECTIONS

You can connect up to four relay units to each viewstation. The CM9760-REL should be used with third-party matrix switchers for hard-wired alarm integration.

To connect a CM9760-REL to a DX9100 viewstation using RS-232 communication:

1.Connect a null modem cable from the relay unit’s RS-232 port to the viewstation’s RS-232 port.

2.Set the DIP Switches on the relay unit for RS-232 communication. Refer to the CM9760-REL Installation/Operation manual.

If using RS-422 communication:

1.Connect a cable from the relay unit’s RJ-45 COM IN port to the viewstation’s COM 1 or COM 2 port via an RS-232 to RS-422 converter.

2.Set the DIP Switches on the relay unit for RS-422 communication. Refer to the CM9760-REL Installation/Operation manual.
