Troubleshooting
1. Do I need to use the included external AC adapter?
You must use the included external AC adapter with the TK-EX3 KVM switch.
2. I have the TK-EX3 connected properly, but my keyboard and mouse don't work.
What should I do?
1. Make sure the power adapter is plugged into your TK-EX3 switch.
2. Verify that your mouse and keyboard are working properly by connecting them
directly to the PS/2 ports on your computer.
3. Try using another set of PS/2 keyboard and mouse.
3. There is video distortion when I connect the monitor to the TK-EX3 receiver
(remote device). What should I do?
1. You can adjust the quality of the video by adjusting the Gain (Resolution
adjustment) and Equalization (contrast correction) knobs on the TK-EX3
receiver (remote device).
2. If you are using a cable longer than 100 meters, you will need to lower your
computer's resolution to 1280 x 1024. The follow is the maximum length of
cable supported by the TK-EX3:
Up to 100 m (328 ft.) with 1600 x 1200 resolution
Up to 150 m (490 ft.) with 1280 x 1024 resolution
If you still encounter problems or have any questions regarding the TK-EX3, please
contact TRENDnet's Technical Support Department.
