Appendix 2 Tally Outputs
The SE-2850 has a D-sub 25 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.
These ports are open collector ports and as such do
not provide power to tally light circuits.
Dielectric strength: Max. DC 24V
Current: Max. 50mA
The pin outputs are defined as follows:
Pin No.
