Tally and Cable Kit options
The tally option is a module providing contact closures for each
video input. As a video crosspoint is selected, the appropriate
relay closes. This closure can be used to light an external lamp for
tally, or can be used for a bi-directional route for an intercom.
The cable kit option is installed in the frame to permit use of an
additional control panel.
