Troubleshooting 31
When I ‘hot-plug’ the Local Unit, the mouse no longer moves.
When connecting the Local Unit to a live system, connect the mouse
cable to the CPU before keyboard connection to ensure the mouse is
enabled.
Try issuing the Mouse Recovery command.
Some of the mouse buttons don’t work.
The Extenders support standard 2/3-button mice (with or without a
wheel). Additional buttons will not operate.
I have an enhanced keyboard with extra keys and indicators. Everything
works apart from these additional features.
As standard, the extender only emulates a generic PS/2 keyboard. To
support other keyboards (or cascaded KVM switches), special firmware
offering a transparent mode may be required. Please contact Technical
Support to discuss your application.
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). The KVM extender accepts line-level audio input only.
The microphone output is barely audible.
See Audio Interface – Using a Microphone, page 41.
Serial
My serial device does not function.
The extender supports serial devices at data rates not exceeding 19.2K
Baud (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.
