Tally Outputs
The HS-1200 has a D-sub 15 pin female tally output port. These connections
provide bi-colour tally information to a number of other Datavideo products,
such as the ITC-100 eight channel talkback system and the TLM range of LCD
Monitors.
The ports are open collector ports and as such do not provide power to tally
light circuits.
The pin outputs are defined as follows:
