Jitter is evident on video.
Adjust the clock and/or phase on your flat-panel. Contact Technical
Support if this fails to improve the situation.
Are you testing a system using a coiled drum of CATx cable? Try
uncoiling the cable. If this solves the video jitter, you should not have a
problem after full installation.
I can’t select the video mode I need.
For non-standard resolutions, choose the monitor manually through the
operating system, and set to ignore DDC. Contact Technical Support if
you have problems selecting your required graphics mode.
Can the extender be used with RGB video?
Yes.
USB
Why does the Extender stop working when I attach a USB hub to the Remote
Unit?
If additional USB hubs are attached to the extender, the maximum
extension distance will be reduced (due to the delay imposed by each
hub). For each connected hub, you may lose up to 10m of extension
distance. Any USB device to which additional USB peripherals may be
attached is a USB hub (e.g. an Apple® USB keyboard).
Will the USB Mini Extender work with USB 2.0?
The extender will operate perfectly through USB 2.0 Host Controllers.
However, the speed will be restricted to that of a USB 1.1 hub (12Mb/s).
Devices that are USB 2.0 compliant will operate if they are backwards
compatible with USB 1.1. If you have a device that demands the high-
speed mode of USB 2.0 then it will not be compatible with the USB
Mini Extender.
Is the USB Mini Extender compatible with all USB devices?
This product range extends the distance at which USB peripherals may
be operated by making full use of the bus timeout period allowed by the
USB protocol. The extender should be compatible with the majority (but
not all) of CPU USB Host Controllers and USB peripherals on the
market.
