NOTE
1. A PS/2 Keyboard is required for proper hotkey function. If you use a USB
keyboard, hotkey feature is disabled.
2. Note that (x) denotes a number key for the selected port number (x = 1 or 2).
Currently only the top row number keys are available for hotkeys. Do not use
the number pad for hotkey commands.
3. When binding the PC ports, port binding is enabled by the hotkey sequence:
ScrLk + ScrLk + Q. All PC ports are bound together. To remove this binding,
use the hotkey sequence: ScrLk + ScrLk + W.
4. Normally, you should have no problems with mouse hot-plugging on a Plug-
and-Play OS. However, a non-PnP OS only performs hardware detection
while booting up - that is why the mouse will lock sometimes.
Mouse Troubleshooting on a non-PnP OS (Linux, Windows NT 4.0):
If you experience mouse lock when hot-plugging mouse on a non-PnP OS
such as Linux or WinNT 4.0, just hit one of the following hotkey commands for
mouse reset according to your mouse configuration on the non-PnP OS:
Hot-Key convention:
The hotkey notation for example (ScrLk + ScrLk + X.) denotes that you should
hit the individual key consecutively one at a time, not simultaneously.

Where is the power supply? I did not find one in the box.
The TK-403KR does not require a power supply. It draws power from the PS/2
connection of your computers. As long as you are connected to the PS/2 port, your KVM
switch will function.
I have the KVM switch connected properly but my keyboard and mouse doesn't
function. Why?
Make sure that the following connections are properly made:
1. Connection of PS/2 mouse and PS/2 keyboard to the KVM switch.
2. Connection of KVM cables to the KVM switch.
3. Connection of KVM cables to PCs.
Can I connect and disconnect the PS/2 cables while the computers are turned on?
Yes, you can connect or disconnect the PS/2 cables while the computers are turned on
because the PS/2 interface is Plug-and-Play and Hot-Pluggable.
Will the KVM switch restore the keyboard settings when switching between computers?
Yes, the KVM switch will restore the custom keyboard settings for each computer. (Cap
lock, Num key, etc.)
How do I switch from one computer to another with the KVM switch?
The TK-403KR supports Push button and Hot-Key commands, so you can switch PCs
by pressing the Push button on the KVM switch or by using the Hot-Key commands listed on
the reverse side of this page.
If you have further questions, please contact Trendware's Technical Support Department.
