SERVSWITCH™ BRAND CAT5 KVM MICRO EXTENDER
5. Configuration
There’s a two-position DIP switch on the bottom of the Remote Unit of the
ServSwitch™ Brand CAT5 KVM and KVM/Serial/Audio Micro Extenders.
Position 1 governs the Remote Unit’s video equalization, while position 2 controls
how the Remote Unit handles keyboard-command recognition.
5.1 Setting DIP-Switch Position 1: Video Distance
The Remote Unit contains video-equalization circuitry which compensates for the
loss in image quality that occurs when you drive video across cables longer than
25 m (80 ft.). If you’ll be running cable between the Micro Extender’s Units to
such distances, you need to configure the Extender for extra equalization before
you install it.
Leave position 1 of the DIP switch in the factory-default UP (OFF) setting if
you’ll be running cable up to (but not more than) 25 m (80 ft.) between the Units.
To boost the equalization if you’ll be running cable between 25 and 50 m (80 and
160 ft.), move position 1 to the DOWN (ON) setting.
If you are not running the cable too far but your video looks bad no matter how
you set this DIP-switch position, the problem is almost certainly being caused by
one of two things. First, check your interconnect-cable routing—does the cable
pass close to a motor, generator, fluorescent lights, etc.? Second, check the wiring
of the interconnect cable. Compare its pinning and pairing with those shown in
Appendix A. (Please realize that signal equalization cannot be exact; regardless of
the setting of this DIP-switch position, the remote video image might never appear
quite as sharp as it would appear with the monitor directly attached to the CPU.)
