models contains six (SW6) or eight (SW8) 3-pole captive screw connectors, each with three pins labeled C, G,
and T, for contact closure and tally indicator devices. The panel also contains a 3-pole captive screw connector
with three +V pins that provide power to the indicator devices connected to the tally (
illustration below right).
Each 3-pole connector is labeled with the number of the HDMI input associated with it. Wire devices to these
connectors as follows:

panel buttons are not visible, connect an indicator
device, such as an LED, to tally output pin
same 3-pole connector.
When the input you are using is selected, the
corresponding tally out pin shorts to ground, which activates the connected indicator.
If desired, attach the power wires for your connected indicator devices to any of the three ports of the
