SERVSWITCH™ BRAND CAT5 KVM/SERIAL/AUDIO EXTENDER
I get black & white instead of color video.
Your CPU probably needs to see monitor ID in order to boot into the correct video
mode. Please contact Black Box Technical Support.
Microsoft Windows 3.x, 95, 98, or 2000, Windows Me, Windows NT, or Windows XP will
only boot into a low-resolution graphics mode.
1. If your graphics card supports VESA DDC (Display Data Channel), configure
the graphics driver by explicitly telling it which make and model of monitor
you’re using, rather than letting the driver configure itself automatically (and
probably erroneously) through DDC, which the Extender doesn’t support at
the remote station.
2. Your CPU might need to see monitor ID in order to boot into the correct
video mode. Please contact Black Box Technical Support.
Connecting a keyboard to the Remote Unit has an adverse effect on the remote video.
Try using a newer keyboard. (Some older keyboards require too high a current
for the Remote Unit to properly drive the video signal.)
The Extender doesn’t seem to work correctly with my LCD panel.
Try reducing the refresh rate of the video signal that your graphics card is
outputting. (The maximum refresh rates supported by most LCD panels
are less than those supported by most monitors.)

I don’t need to use a keyboard in my application, but the Extender doesn’t work at all unless I
have a keyboard line running from the Local Unit to the PC or KVM switch.
The Extender’s Local Unit normally operates using the 5 volts of DC power that
the attached CPU or KVM switch supplies on its keyboard port. Even if you’re not
using a keyboard at either the local or remote user station, you should run a cable
from the Local Unit’s CPU-port keyboard connector to the keyboard port of the
CPU or KVM switch in order to power the Local Unit. If this is not possible, please
call Black Box Technical Support to discuss your application; you might need a
keyboard-port power supply for the Local Unit.
