For analog audio output, connect an amplifier,
3.
powered speaker or other audio device to the
3.5 mm, 5-pole captive screw connector. See the
diagrams at right for the appropriate wiring for your
application. For unbalanced audio, connect the
sleeve(s) to the ground contact; do not connect
the sleeve(s) to the negative (-) contacts.

contact input pin to ground to select the corresponding input. Connect a tally output pin and tally voltage pin to light an LED to
indicate that the corresponding input is selected.
NOTES:
• Input selection and tally feedback behavior cannot be changed: the contact closure and tally ports cannot be
configured using GC software.
• Input selection via contact closure is equal in priority to input selection from the front panel or from software.
• When an input is selected, the corresponding tally port is set to logic low, allowing voltage to pass through that tally
output pin, providing power for an indicator LED. If the tally port is connected to an Extron Show Me cable, the LED in
the cable lights.
• Show Me cables are available only as part of an Extron TeamWork kit.
Follow the wiring instructions for either an Extron HDMI Show Me cable (see below) or an external push button keypad (see the
HC 400 Series User Guide), as appropriate.
Extron HDMI Show Me cable
For each Extron Show Me cable (part of a TeamWork system), connect the red wire from the
cable pigtail to the associated pin of the contact closure input connector on the HCT 103
transmitter and connect the black pigtail wire to the associated pin on the tally connector (see the
system diagram in

NOTES:
• For Show Me cables, the ground pin is optional.
• Do not connect Show Me cables to the +V pin of the tally port. The source device
provides the +5 VDC supply voltage needed to illuminate the Share button. Some
sources (such as mobile devices) do not provide sufficient voltage to light the button.
• Digital (HDMI) Show Me cables support embedded audio.
Analog Show Me cables do not.
