CONNECTING DEVICES THROUGH THE COMMUNICATION PORTS
The CM6800 Matrix Switcher/Controller provides eight communication ports on the rear
panel for connecting peripheral components. You can connect a wide variety of devices,
such as keyboards, a personal computer (for either the CM6800 MGR package or ASCII
control), alarm and relay boxes, and multiplexers. Instructions are provided in this section
for the most commonly used connections.
The CM6800 communication ports are labeled COM 1 through 8. Port 1 is available either
as a DB9 connection, or as an RJ-45 connection. Ports 2 through 8 are RJ-45 connections.
In the programming menus these are referred to as serial ports 1 through 8.
