I would like to know how to go about hooking up a URI to the link port of the CAT 300 controller.

We have a remote site and the computer went down, so I want to put the Cat controller back in place and still have Allstar connection.

The problem I have is the link port has to see a COR from the link Device (usually a Radio) . How do I get COR from the URI?? so that port 1 will send transmit signal to Repeater TX??
