specifications
IMPORTANT NOTE
The maximum cable lengths supported vary widely between devices and
cables. It may be possible to use cables that are longer than those specified
below with certain PCs and peripherals but this cannot be guaranteed. If you
experience problems try using shorter cables.
A1. Keyboard, monitor and mouse to AdderView GEM
All of the shared devices plug directly into the relevant ports at the rear of the
AdderView GEM. If you use an AT style keyboard you will need an AT (5 pin DIN
female) to PS/2 (6 pin mini-DIN male) converter.
Cable specification (self-powered operation):
Keyboard, monitor and mouse cables should be no longer than 2 metres.
Cable specification (with optional power adapter):
Keyboard, monitor and mouse extension cables can be used to increase the
distance from AdderView GEM up to 10m. Most keyboards and mice will also
operate at distances of 20 metres.
A2. AdderView GEM to PCs 1 to 4
Cable specifications:
Video - 15 pin high density male D connector to 15 pin high density male D
connector wired as a standard VGA PC to monitor cable. There are two types

constructed with coaxial cable cores. Cheaper 'data' cables are often used, but can
degrade video quality if used over longer distances. Avoid using 'data' cables longer
than 2 metres unless the video quality is not important. Good quality coaxial video
cables may be run at distances up to 30 metres with little loss of video quality. If you
