The Duo CPU Module has the ability to communicate with your monitors via an RS-232 serial link. Certain
monitors include an external control port at the rear panel and upon receiving the correct control code from the Duo
unit, will perform functions such as switch to and from an AV source.
In order to allow this function to occur, three areas must be addressed first:
1. Your AV supplier must cable a video source to each monitor.
2. The correct configuration file must be specified in Step 3 of the configuration Wizard. See Chapter 8
for more details on the Setup Wizard.
3. The correct DVT Serial cable must be made and connected.
