Do I need to use the included external AC adapter?
It is recommended that you use the included external AC adapter with the TK-804R KVM
switch.
I have the KVM switch connected properly, but my keyboard and mouse don't work. What
should I do?
1. make sure the power adapter is plugged into your KVM switch.
2. Make sure your PS/2/USB ports are working properly by connecting your mouse and
keyboard directly to the PS/2 or USB port on your computer.
3. Once you confirm that the PS/2 or USB ports are functional, please reboot your
computers, and try to use the KVM switch again.
4. If your computer is running Windows 98SE, you may need to download and install the
USB hot fix. Please go to this link for download and installation instructions:
http://support.microsoft.com/kb/q240075. Once the hot fix is installed, follow the
installation instructions in Section 2.
Can I connect or disconnect the KVM cables while the computers are turned on?
Yes, you can connect or disconnect the KVM cables while the computers are turned on,
because the interface is Hot-Pluggable.
Will the KVM switch restore the keyboard settings between computers?
Yes, the KVM switch will restore the keyboard settings when switching between
computers. (i.e.: Cap lock, Num key, etc.)
How do I switch from one computer to another with the KVM switch?
You can switch computers by pressing the Push Buttons on the KVM switch or using the
Hot Key commands. Go to Section 3 Operation for more information.
I already have the TK-207K/TK-407K. Can I use the KVM cables that come with the TK-
207K/TK-407K with the TK-804R?
You cannot use the KVM cables that come with the TK-207K/TK-407K. The pin layout
for the TK-804R is different from the TK-207K/TK-407K. You must use the TK-CU06/TK-
CU10/TK-CU15.
Does the keyboard and mouse have to be the same type (e.g. USB or PS/2)?
One device can be USB while the other device is PS/2.
If you still encounter problems or have any questions regarding the TK-804R, please contact
TRENDnet's Technical Support Department.
