SERVSWITCH™ WIZARD EXTENDER
7. Troubleshooting
If your ServSwitch™ Wizard Extender is not providing sharp video, you can force it
to apply automatic video compensation as described in Section 7.1. If one or more
of the red, green, and blue colors in the video it’s displaying seems separated or
offset, have the Extender report how much skew is occurring (and install the
ServSwitch Wizard Skew Compensator, if necessary) as described in Section 7.2.
If you have some other kind of difficulty with your Extender, see if the problem
is listed in Section 7.3 and, if so, try the suggested remedies. You can also, at any
time, reset the Extender itself as described in Section 7.4. If nothing helps, get the
Extender’s firmware-revision level as described in Section 7.5 if possible, then call
Black Box Technical Support as directed in Section 7.6. If you need to ship your
Extender, see Section 7.7.
7.1 Forcing Automatic Video Compensation
Sometimes, when the Extender is operating with a manual video-compensation
setting (see Sections 4.2.1 and 4.2.2.A), situations can arise in which that setting no
longer provides the best video—for example, if you swap in a different cable, CPU,
or monitor. If you would rather not spend a lot of time trying to find a better
manual compensation setting—especially if the replacement equipment is only in
place temporarily— you can force the Extender to override the current manual
setting and apply its automatic video compensation instead, which might result in a
better picture being displayed.
To do this, take these steps:
1. Go into configuration mode by pressing the hotkeys followed by [Enter] at
the primary control station’s keyboard.
2. Force the Extender to apply automatic video compensation by issuing the [F]
[2] [Enter] command. (“[F] [2]” is the letter “F” followed by the number “2”,
not the [F2] function key.)
3. Press [Enter] again to exit configuration mode.
The Extender will save this value in its nonvolatile memory, overwriting the value
that the manual-compensation DIP-switch setting corresponds to. If you want to
have the Extender go back to using a manual-compensation value read from its
DIP switch, you’ll have to move the DIP-switch positions, even if you just move
them to a different setting for a second before returning them to their previous
setting.
