WN-5230-S VideoWall User’s Guide

To allow proper cooling, the minimum required clearance to the rear of the Unit is 4 inches.

If installed in a video wall configuration, a minimum of 12 inches to the ceiling from the top of the highest display is needed if the units are installed from the front.

Cables and Signals

Video connections from the signal source to the display depend on the type of signal supplied by the source. The compatible data inputs are: PC 800x600 (SVGA), PC 640x480 (VGA), MAC 800X600 or 640X480, 31.5 kHz and 15.75 kHz (progressive scan) RGBS video, composite video, and S-video.

The Loop-Thru video output uses a standard 15 pin VGA type connector for output to an external computer monitor or to another WN-5230-S. The format of the Loop-Thru video is same as the source video.

The video cables used should be high quality and shielded to insure the best image quality when displayed. VGA and MAC will have RGB with separate H- Sync and V-Sync. RGBS video will come out RGBS with the composite sync on the connector’s H-Sync pin. RGB Sync on Green sources will loop-thru RGBS-Sync on Green. Displays with the VIM-300 option also have Composite Video and S-Video loop-thru connectors.

Using poor quality cables can lead to picture noise, jitter and crosstalk. Even good quality cables that are longer than 10 feet may produce noise and jitter in the image if the source signals are not amplified.

Control data enters the display via the RS-232 In connection, and is supplied to an adjacent display (if used) via the RS-232 Out connector. High quality shielded cables designed for RS-232 communication should be used to ensure proper data transmission and control. The wiring of the RS-232 cables must be straight through (pin 1 to pin 1, pin 2 to pin 2, etc…) and not wired for “null modem”.
