Signal Selection
The RGB signal connected to the IM transmitter is delivered to the display device
(e.g., projector) via the RGBHV output of an IM receiver. The composite video
signal connected to the IM transmitter is delivered to the display device (e.g.,
projector) via the composite video output of an IM receiver. Each IM transmitter
possesses a SELECT button (IM transmitters with video have two SELECT
buttons) that activates an input. The receiver automatically routes the last activated
input to the RGB or composite video 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.
NOTE: For proper operations and performance of every iMedia system, always use
CresCAT-IM cable.
