When the corresponding input is on-air, the
associated tally pin is closed, creating a contact
closure.
Note:
• Tally wiring can be difficult. Consult with your
facility engineer before undertaking any tally
wiring.

General Purpose Interface (GPI)
The switcher has 24 GPI inputs/outputs
corresponding to the pins on the GPI port. The GPI
inputs/outputs are are arranged into 3 banks.

GPI Port
Banks configured as GPI inputs are used to trigger
memory recalls, transitions, and Aux bus input
changes.
Banks configured as GPI outputs allow your switcher
to trigger actions on external devices.
To configure GPI banks:

outputs.
•
GPI
— The bank is configured as GPI inputs.
Note:
• Every pin in the selected bank initially goes low
when you change the bank from a GPI output to
GPI input.
GPI Output Banks
Banks configured as GPI outputs have output pins
assigned as follows (Pin 1 is the top right pin when
looking at the GPI Port).
