DVR MANAGEMENT
The Server Alert Configuration Utility can be used to send events to the CM9760-DT data translator or the CM9760-REL relay
unit.
The server state sends a string to the data translator. The string is different for each recorder so the matrix recognizes which
recorder has the problem.
The server state activates the relay unit. The server state is configured to activate a specific relay port in case of a problem.
DATA TRANSLATOR CONNECTIONS
The CM9760-DT should be used with Pelco matrix switchers, such as the CM9760 matrix.
1. Connect a null modem cable from the CM9760-DT’s COM A port to the COM 1 or COM 2 port on the viewstation.
2. Connect a null modem cable from the CM9760-DT’s COM B port to the COM 1 or COM 2 port on the CM9760-CC1.
3. Set the jumpers in the data translator for baud rate and parity. Refer to the CM9760-DT Installation/Operation manual.
NOTE: You can also connect the CM9760-DT to one of the CM9760-CC1 SERCOM ports for RS-422 communication.
