iMedia Table Mount Computer Center
2 • iMedia Table Mount Computer Center: IM-TCC
The iMedia transport system port is capable of managing computer RGB and
audio signals simultaneously through one CresCAT-IM wire, simplifying
installations.
Routing CresCAT-IM cable is less expensive and much simpler than routing
multi-colored, multi-conductor coax cable. All Crestron products using the
iMedia transport system are capable of sending and receiving iMedia signals via
CresCAT-IM cable. Installation of any iMedia device is as simple as installing
one iMedia cable from output to input. Installations are flexible, affordable, and
fast.
Up to three iMedia transmitters can be installed in an iMedia system. Pressing
the SELECT button on any iMedia transmitter makes that input active,
overriding the previously selected input. Holding the SELECT button for five
seconds powers down the system.
The pin assignment is based on the EIA/TIA 568B RJ-45 Jack standard.
Power is supplied to the IM transmitters via the audio circuit.
To determine which pin is number 1, hold the cable so that the end of the eight
pin modular jack is facing you, with clip down and copper side up. When
looking down at the copper connections, pin 1 is on the far right.

NOTE: Power is supplied to pins 4 and 5 from the IM-RX1 or IM-RX3.
Signal Selection
The VGA signal connected to the IM transmitter is delivered to the display
device (e.g., projector) via the RGBHV output of an IM receiver (IM-RX1 or
IM-RX3). Each IM transmitter possesses a SELECT button, which activates that
input. The receiver automatically routes the last activated input to the RGB
output and deactivates any prior selection. In addition, the display's power and
input selection commands can be controlled via the IR or COM port.
Video Resolution and Cable Length
The receiver can accomplish frequency compensation on each input to achieve
correct operation. This compensation scheme is effective for CresCAT-IM
cables as long as the maximum skew of 15 ns per 100 m is not exceeded.
