6. ITC-100 Tally Input

If you are using the ITC-100 with a Datavideo product, you do not need to worry
about tally information, as it has already been customized for the ITC-100.
However, if you are using the ITC-100 with equipment of other manufacturers,
please see the following tables for PIN definitions of the ITC-100 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.
