3. Using the KVM Switch

To alternate between computers, you can use the Push Buttons on the KVM
Switch or the Hot-key commands via keyboard.

Hot-Key Commands

A keyboard hot-key command consists of three keystrokes:

Hot-Key command = ScrLk + ScrLk + Command key(s)

After pressing the ScrLk key, you have 2 seconds to press the ScrLk key again.
You then have another 2 seconds to press a command key. If you do not press
a key within 2 seconds, the switch will exit hot-key mode.

NOTE

1. Hotkey command works on top row numbers keys only.

2. When the binding of PC & Audio/Mic port switching is enabled by the hotkey
sequence, any PC and Audio/Mic switching are bound together.

3. For non-PnP OS(Linux, Windows NT 4.0), please use the following

commands to reset the mouse setting:

Troubleshooting

Where is the power supply? I did not find one in the box.

Q1:

The TK-408K does not require a power adapter. It draws power from your

A1:

computer's PS/2 connections. As long as your KVM Switch is connected to the
PS/2 port, it will receive the necessary power to function.

I have the KVM switch connected properly, but my keyboard and mouse don't

Q2:

work.

Please make sure your PS/2 port is working properly by testing it with your

A2:

other PS/2 devices. Once you confirm that the PS/2 port is functional, please
reboot your computers, and try to use the KVM switch again.

Can I connect and disconnect the PS/2 cables while the computers are turned

Q3:

on?

Do not try to connect the KVM Switch to the computers while the computers

A3:

are in powered-on state, because the computers may have difficulty recognizing
your shared PS/2 keyboard and PS/2 mouse.

Will the KVM switch remember the keyboard settings between computers?

Q4:

Yes, the KVM switch will remember the keyboard settings when switching

A4:

between your computers. (i.e.: Cap lock, Num key, etc.)

How do I switch from one computer to another with the KVM switch?

Q5:

You may switch between computers by pressing the Push Buttons on the KVM

A5:

switch or by using the Hot-Key commands via keyboard. For a list of Hot-Key
commands, refer to the "Quick Reference Sheet for TK-408K".

If you still encounter problems or have any questions regarding the TK-408K, please
contact TRENDnet's Technical Support Department.
