SERVSWITCH™ BRAND CAT5 KVM MICRO EXTENDER
I only need video—not keyboard or mouse control—but I can’t get a picture.
Even if you are only using the Micro Extender for video extension—to drive video
to a remote monitor—the Micro Extender’s Local Unit must still be attached to
the PC’s keyboard port, because that’s where it gets its power. If your application
makes it impossible to connect the Micro Extender to a keyboard port, call Black
Box Technical Support about getting an alternative power supply for the Local
Unit.
I get a constant vertical wobble down the screen. What is the cause of this interference?
1. The interconnection cable could be located too close to a source of very
strong electrical-power interference; reroute the cable if possible.
2. If the wobble forms a standing “beat pattern,” the Micro Extender is probably
being affected by a very strong signal from a nearby broadcast transmitter. Try
changing the vertical refresh rate slightly (for example, from 60 Hz to 70 Hz
or vice versa).
3. You might require an alternative power supply for the Remote Unit. Call
Black Box Technical Support.
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, Windows 95, Windows 98, Windows 2000, Windows ME, or
Windows NT 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.
2. The 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.)
