Remote Tally port — If desired, to remotely identify the currently selected
input, plug a locally-constructed device into this 3.5 mm, 4-pole captive
screw connector. Connect the power wire for the device into the +V pin and
connect the ground wire for the each indicator into the corresponding tally out pin, 1, 2,
or 3.
When an input is selected, by either contact closure of front panel selection, the
corresponding tally out pin shorts to ground, closing the circuit and lighting the
connected indicator (LED).

NOTE: Do not use Extron UTP23SF-4 Enhanced Skew-Free AV UTP cable or STP201
cable to link the switching transmitter and receiver. The DTP T USW 233 Tx/Rx does
not work properly with these cables.
IR and RS-232 connector wiring
Power supply wiring
The power supply included with the switching transmitter can normally power
both units.
If you have removed the ground jumpers (see
page 19) because of ground potential differences, one unit of the pair cannot
remotely power the other unit. Each unit requires a local power supply.
