							AdderLinkInstallation and UsePage 61. IntroductionThank you for purchasing the AdderLink extender. Your AdderLink is designed to
transfer keyboard, video, mouse and RS232 signals up to 200 metres over Category
5 twisted pair cable.  The AdderLink system consists of a transmitter (XL) and a
receiver (XR) unit that are connected together by a twisted pair cable. The XR unit
connects to your keyboard, monitor and mouse and the XL unit connects to the
computer system that is to be controlled.
The AdderLink extender is supplied in both standard (AdderLink) and enhanced
(AdderLink Gold) formats. In addition to the features supported by the AdderLink,
the AdderLink Gold system supports stereo audio and microphone signals and extra
connectivity options. This additional connectivity enables a second
keyboard/monitor/mouse set to be connected to the XL unit and an additional
computer system to be connected to the XR unit.
1.1 AdderLink featuresEnables a keyboard, monitor, mouse and RS232 device to be located up to 200
metres from a computer. Uses a single Category 5 (or better) unshielded twisted pair cable to carry all the
keyboard, video, mouse and RS232 signals. Fine user-adjustable video compensation enables the video quality to be
maximised for any given length of cable. The video compensation only needs to be adjusted once during setup. The
chosen compensation setting is retained in EEPROM memory even when the
AdderLink is powered off. Mixed AT/PS2 keyboards and PS2/RS232 mice supported as standard. Supports Microsoft IntelliMouse and other common wheel mice. Password security prevents unauthorised use. Supports high bandwidth monitors at resolutions up to 1600 x 1280. Supports keyboard modes 1,2 and 3 and mouse prompt and stream modes for
maximum compatibility. 
						

							AdderLinkInstallation and UsePage 7 Power and activity indication confirm correct operation. Standard cable connections make installation easy and inexpensive. Robust metal case ensures good shielding and video quality.  19 inch rack mount kit available.  Supports IBM PC compatibles and RS6000 computers.
1.2 Additional AdderLink Gold featuresSupports stereo audio and microphone signals. Provides an additional user port  (keyboard/monitor/mouse/speaker/microphone)
on the XL transmitter unit enabling the computer to be controlled from a location
close to the XL transmitter as well as a location close to the XR receiver. Provides an additional computer port (keyboard/monitor/mouse/speaker/micro-
phone) on the XR receiver unit enabling the user to control a local computer in
addition to the remote computer that is connected via the twisted pair cable. Front panel indicators show the currently active user port and the currently
selected computer.
