Tally Input

If you are using the ITC-300 with a Datavideo product, you do not need to worry about
tally information, as it has already been customized for the ITC-300.
However, if you are using the ITC-300 with equipment of other manufacturers, please
see the following tables for PIN definitions of the ITC-300's Tally A and B inputs.
Contact closure between a tally pin and the ground will turn ON the Tally LED. For
example, on Tally Input A, if the connection between pin 1 and pin 4 is closed, RED
Tally LED on Channel 1 will be turned ON; if the connection between pin 13 and pin 4 is
closed, GREEN Tally LED on Channel 3 will be turned ON.
