KVM Extenders

The AdderLink Range of KVM Extenders provide convenient and remote control of a computer from 10m to 10km distance. KVM Extenders are easy to install and encompass analogue (VGA, PS/2) or digital (HDMI, DVI, DisplayPort) video and USB extension over CATx or fibre.

A transmitter (or encoder) is placed at the computer and a receiver (decoder) is placed by the remote user station, along with a display monitor and control devices, e.g. keyboard, mouse, touch screen, graphic tablet or other USB device. These are connected together by means of a twisted pair copper (referred to as Cat X) or fibre optic cable.

Analogue KVM Extenders

The X100 and X200 extends KVM over 300m as a single point-to-point connection. A second computer can also be extended by using a CAM (Computer Access Module) VGA or DisplayPort dongle connected to the second Ethernet port. Dual computers are not simultaneously transmitted but you can switch between them using ‘hotkeys’.

X100 – extends VGA + PS/2 + Audio

X200 – extends VGA + USB 1.1 + Audio
