Crestron IM-WCC iMedia Wall Mount Computer Center
iMedia Wall Mount Computer
Center: IM-WCC
Introduction
Features and Functions
The IM-WCC is part of the Crestron iMedia line of network devices, room
control systems and signal routing solutions. The iMedia devices currently
include two receivers, IM-RX1 and IM-RX3, and three transmitters, IM-WCC,
IM-TCC, and IM-FTCC-B.
The iMedia Wall Mount Computer Center supports a single computer video and
audio connection in a standard double gang electrical box.
This device uses iMedia (IM) technology utilizing a single CresCAT-IM cable
to transmit computer RGB and stereo audio signals to a single projector or
plasma display. A typical XGA signal (1024 X 768 pixels at 60Hz) can be
transmitted up to 84 feet using iMedia, while higher resolutions up to
1600 x 1200 can be handled over shorter distances. Audio is transmitted
digitally at 20-bit, 48 kHz resolution. To facilitate connection of audio, video,
and computer equipment, all media, power and control signals are routed via a
single CresCAT-IM cable for an uncomplicated installation.
NOTE: The IM-WCC is not a Cresnet

The iMedia System
Using a new, proprietary signal routing solution, RGBHV, audio, power and
control signals are all transported using a single cable solution called iMedia.

iMedia Wall Mount Computer Center Crestron IM-WCC
The iMedia transport system port is capable of managing computer RGB and
audio signals simultaneously through one CresCAT-IM cable, 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.
