DVR MANAGEMENT

If the DX9200 DVR system is connected to a matrix switcher, the operation of the system can be managed with the Server Alert Configuration Utility. If recorders are not recording or there is no communication with recorders, this utility sends alarms to the matrix switcher.

If the DX9200 system is connected to a Pelco matrix switcher, such as the CM9740 or CM9760, alarms are sent through a data translator. For non-Pelco matrix switchers, alarms are sent through a relay unit.

NOTE: Refer to the Server State section for more information on the Server State application.

DATA TRANSLATOR CONNECTIONS

The CM9760-DT should be used with Pelco matrix switchers, such as the CM9740 or CM9760.

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.
