USB
One Universal Serial Bus (USB) "B" connector
provides a communications link. USB is a
connectivity specification developed by the USB
Implementers Forum that provides a single,
simple, standardized way to connect devices to a
computer. USB shielded cables contain two wires
for power +5 volts (red) and ground (brown) and a
twisted pair of wires (yellow and blue) that carry
data.

PHONE
Connect this standard mini phone jack (12 mW, 32 ohm load) to the plug of a 3.5 mm
external headphone set plug (not supplied).
Plugging in the headphone cuts off the speakers.
The headphone output is for WAV and Line audio only. It does not carry the microphone
signal.
Use the AUDIO OUT on the TPMC-CH-IMC for the microphone signal.
MEMORY EXPANSION
The onboard memory may be enhanced with the addition of a Type II
compact flash memory (up to 160 MB).
The flash memory slot is accessible on the rear panel of the unit.
QM IN (QuickMedia Input)
The eight-pin RJ-45 QuickMedia transport port accepts Crestron Certified Wiring
carrying audio, video, and microphone signals.
The QM input port conforms to the 568B wiring standard. Refer to the following table
for connector pinouts.
NOTE: The QM port is not connected through any "IMC" interface.
NOTE: Only one video source may be displayed on the touchpanel at a time.
NOTE: TPMC-12, TPS-15, and TPS-17 touchpanels do not support RGB.
