Unit-to-Unit Commands (DV-200)

Unit-to-Unit commands (xCyy)

Whenever a particular event occurs at a site, it can be used as a trigger for the Davicom to send a specific Unit-to-Unit Command (UUC) flag (1C01 to 1C08) to a receiver Davicom unit at another site.

The receiver Davicom will send a UUC acknowledgement receipt to the sender Davicom and its active/normal state will follow that of the sender UUC. The received UUC flag can then be used as a qualifier, or an operand for any input in the receiving Davicom unit to control desired actions.

To configure your Davicom unit so that a UUC will be sent to another Davicom unit, click the Unit Configuration icon () in DavLink and select Unit-to-Unit Command in the Flags tab.
