Tally Outputs
The HS-1500T 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:
