Panasonic AV-HS400AN manual Pins 1 to 9 must satisfy the following conditions, Current, Max. 50 mA

6. External interfaces

6-3. Tally connector

The tally connector comes with tally output, output enable, power supply or fan alarm output pins.

The output signals from the tally output pins are for lighting the tally lamps, and these outputs are open collector outputs.
