System Cabling

The Cameron Video Wall manual gives an overview of the system cabling, these details are also shown on the Video Wall Overview page. Unfortunately, no technical details for the Video Wall hardware are available, so the purpose of this page is to document the details of the interconnection cabling.

The information on this page is based on some "discussions" with Geoff Boyd and reverse engineering my Video Wall hardware, whilst the information is believed to apply to all Memotech Video Wall systems, it has only been verified on the very limited collection of hardware that I have.
