Frequently Asked Questions - VS-88UT Kramer
How do I connect sources and displays to the VS-88UT?

Can I control the switcher via computer?
Yes, you can control it via RS-232 using a serial cable (DB9). Commands are available in the manual. Some models also support Ethernet control with an optional upgrade.
What video resolutions does it support?
The VS-88UT supports up to WUXGA (1920x1200) and 1080p HDTV. Lower resolutions like XGA, SVGA, and VGA are also supported.
How do I switch inputs manually?
Use the front panel buttons labeled INPUT and OUTPUT. Press an INPUT button, then an OUTPUT button to route that input to that output. The LCD or LEDs will confirm the selection.
What is EDID management and how does it work?
EDID management allows the switcher to store and supply display EDIDs to sources. You can copy EDID from a connected display or use default EDIDs via software or dip-switches.
Can I use this on a PoE switch?
No, the VS-88UT is not PoE powered. It requires the included power adapter or direct AC power. Do not connect it to PoE equipment.
How do I reset the unit to factory defaults?
Hold the reset button (located on the rear panel) for 5 seconds while power is on. All settings will return to default.
What should I do if no signal appears on the display?
Check cable connections and ensure the correct input is selected. Verify that the source is powered and outputting a supported resolution. Try swapping cables or ports to isolate the issue.
Is the VS-88UT compatible with audio embedding?
Yes, the UTP cables carry both video and audio (analog stereo). Audio follows the video routing. Ensure your source and display support audio over UTP.
How do I update the firmware?
