The AdderView GEM is the ultimate in desktop KVM convenience and allows up to four computers to be controlled from a single keyboard, monitor and mouse. All connections are made at the rear and with Adder's own high specification VKVM cables, your whole installation can be completed within minutes.

GEM is extremely compact and takes up very little space on your busy desktop or in a crowded server room. Available in either two or four channel models GEM is designed for ease of use and maximum compatibility with new and existing computer systems. Often low-cost is associated with low-specification, but not in the case of the GEM. Like all Adder switches GEM features SmartBoot, which intelligently allows all connected portable or desktop computers to boot as if they had their own dedicated keyboards and mice attached. It also supports PC/AT and PS/2 systems and provides high video bandwidth with low distortion at screen resolutions up to 1900 x 1440. This makes the GEM the ideal choice for use with larger monitors in CAD or DTP environments. The latest monitors equipped with DDC interfaces are also supported and this facilitates true "Plug-and-Play" compatibility.

GEM offers the user many choices for channel selection. Keyboard hot-key, mouse switching, front panel operation, RS232 and optional RC1 remote control switching are all provided as standard and access to connected computers can also be restricted using the GEMs security password protection feature.


The GEM is ideal for SOHO (small office, home office) workers, hardware and software developers, test technicians, network managers, support desks or any environment where the need to control multiple computers from a single keyboard, monitor or mouse is required.
