• Contact In — If desired, for contact closure control, plug a contact closure device
into this 3.5 mm, 4‑pole captive screw port. Momentarily short the pin for the
desired input (1, 2, or 3) to G to select that input. To force an input to be always
selected, leave the short in place (see
wiring details).
NOTES:
• Contact closure control overrides front panel input selections.
• For contact closure control, auto‑switch mode must be off (see
an Input on page 18).
• Tally Out— If desired, to remotely identify the currently selected input plug a device
into this 3.5 mm, 4‑pole captive screw connector. Connect the power wire for the
device into the +V pin and connected the ground wire for each indicator into the
corresponding Tally pin 1, 2, or 3. When an input is selected, by either contact
closure or front panel selection or SIS commands, the corresponding Tally pin
shorts to ground, closing the circuit and lighting the connected LED (see
Wiring on page 15 for wiring details).
• RS-232— Plug a serial RS‑232 device into this 3.5 mm, 3‑pole captive screw
connector for remote control of the DTP2 T 203 (see
Wiring on page 13 for wiring details).
LAN port — If desired, use an RJ‑45 cable to connect this port to a LAN via Ethernet
I
for control of the device (see
on page 13 for wiring details). This port has two LEDs:
Link LED — Lights green steadily to indicate a LAN connection.
•
• Signal LED — Blinks amber to indicate LAN signal activity.
