perform soft reset to KVM switch by press “BANK” button and last port button at the
same time.
■
Do the hard reset by unplug the power then plug in again.
2. The computer boot up fine, but keyboard doesn’t work
„
PS/2 keyboard or PS/2 mouse port is not designed for Hot Plug. USB mouse and
keyboard can Hot Plug, but need to wait few seconds for Computer bus emulations.
„
Don’t press any keys on the keyboard while the selected computer is booting up.
Otherwise it might cause the keyboard error or keyboard is not detected at Host side.
„
Make sure the keyboard works when directly plugged into the computer.
„
Try a different keyboard, but use only 101, 102 or 104-key keyboard.
3. The Mouse is not detected during PC boot up
„
Make sure to plug in mouse first, then plug in keyboard.
„
Make sure the USB or PS/2 mouse works when directly plugged into the computer.
„
Avoiding moving the mouse or pressing the mouse buttons when switching ports.
4. No video signal display on the remote monitor
„
Please go to check all of VGA cables & connector and CAT.5 cable & connector are
firmly connected.
5. Video signal is foggy or unclear on the screen
„
Please check if the VGA connector connected firmly. Check if the VGA resolution is too
high for the length of CAT.5 cable being used. If the problem happened at VGA resolution,
to shorten the CAT.5 cable length or reduce VGA resolution.
„
It is highly recommended to use “optimal CAT.5 cable length” to get the best video
quality and not waste unnecessary CAT.5 cable.
„
If the CAT.5 Receiver is not connecting a local computer, please make sure the monitor is
grounded properly.
6. VGA resolution output mismatch with the monitor’s
The KVM switch will provide DDC information to all the PC VGA board. If both the local
console’s monitor and KVM switch are turned on before the PC boot up, or if the PC boot up
faster then the KVM switch, the PC miss the DDC (Data Display Channel) information that
causes the VGA resolution output mismatch with the monitor’s.
In this case, please turn off the PC wait few minute then turn on again.
