Each Encore Controller provides one 25-pin D connector for issuing tally “relay closure”
commands to external devices. Eight tally circuits are provided. Please note:
• Tally outputs provide dry-contact relay closures between signal pairs or contact
closures to ground, whenever the corresponding input source is selected for
display on a Program output.
• Tally outputs may be used to signal when input devices (cameras) are “live.”
• Each contact has a rating of 1 Amp at 30 VDC, and 0.5 Amps at 125 VDC.
• A mating connector is required — see the diagrams below.
