30 CAT5/5e KVM Extender Range
The PC won’t boot into the correct graphics mode
The extender includes DDC emulation for all standard resolutions and
there should not normally be any issues.
For non-standard resolutions, you will need to explicitly set the
resolution in your operating system configuration ignoring the DDC
data read from the Local Unit.
Contact Technical Support if you have problems selecting your required
graphics mode.
Note: DDC emulation is not provided on SUN extender models.
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.
Can the extender be used with RGB video?
Yes.
Serial
My serial device does not function.
Check that the data rates of the device, extender units and PC COM port
are all the same.
Check the type of flow control used by the device and CPU. The
extender supports various combinations of RTS, CTS, DTR, and DSR.
Some systems may require a wiring adapter to transfer RI and DCD.
Attach the device directly to the serial port on the PC and test whether
the problem is a PC or extender problem.
Some serial devices cannot be hot-plugged. Try connecting the device to
a powered Remote Unit prior to booting the system.
Certain serial devices (such as Wacom graphics tablets) dynamically
change their baud rates. These products are not generally supported
(although you may want to ask the device manufacturer if a fixed rate
driver is available). You may also want to consider using a KVM
Extender supporting Audio/Serial range as these have a transparent
serial port (up to 19.2Kb).
