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 CAT5 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.
6.2 Audio
The audio is very quiet.
The audio I/O is line-level and requires amplified speakers and connection to
devices providing line-level I/O.
The audio is loud but distorted.
Check that the audio input is not greater than line level (4V peak-to-peak). Micro
Extenders accepts line-level audio input only.
The microphone output is barely audible.
See Appendix B: Audio/Serial Ports, page 44.
6.3 Serial
My serial device does not function.
The extender supports serial devices at data rates not exceeding 19.2K Baud
(although 38.4K operation might be possible with certain equipment).
Check the type of flow control used by the device and CPU. The extender supports
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.
