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®device.

Functional Summary

• One computer RGB input connector

• One computer audio input connector

• One iMedia RJ-45 output connector (on the rear side)

• Power on/off SELECT button and indicator

• Rotary local volume control

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.
