Question about Trendware TK-207K 2-port USB KVM Switch

PC start up problem

When my PC is connected to the KVM switch it does not start up properly.  The computer boots up but it never quite finishes the process.  I am stuck looking at my desktop without the ability to use any applications.  If I unplug the switch and connect the monitor, mouse and keyboard directly to the PC I am back in business (after rebooting).

Mac keyboard not working through SV211KDVI on windows

Chances are that the distance between the keyboard & the PC computer is attenuating the signal of the keyboard below the threshold (or level) required for interfacing with the PC computer.

Perhaps a shorter KVM cable between the KVM unit & the PC computer could be helpful.

My computers seem to have become somehow linked by the KVM switch

The GCS632U is just one KVM switch. But if you're going to check it out, it has actually two separate connections.

It will just switch once you toggle from one computer to another.

Try to power cycle the KVM switch.

1. Shut off both computers.
2. Disconnect the KVM switch from the computers. (make sure that not even a single cable is connected to the computer, even the audio).
3. Leave it disconnected for 10 minutes.
4. Reconnect the KVM and boot up the XP first.
5. Boot up the Vista, try to toggle from one computer to another.
6. LASTLY, shut off the Vista and see if same problem will occur.

If you get the same problem, then you need to contact IOGEAR and have them RMA the device. Because this is the first time that I heard of this problem.

Thank you and good luck!

Have a GCS634U KVM that keeps failing to switch. acts like it lost the keyboard

This GCS634U was designed to work with USB keyboards and mice.

First, you need to make sure that your using a direct USB keyboard (no PS/2 to USB adapter).

Second, connect the keyboard directly to the computer and make sure that it's working correctly.

Third, check the connection between the KVM switch and the computers. Try to connect the USB cables of your KVM into different USB ports of the computers.

Last, try to use different USB keyboard to see if the issue is the KVM or the keyboard.

Try to power cycle the KVM switch. Disconnect the KVM from the computers and make sure that there's no even one cable connected to the computers.

Leave the KVM switch disconnected for 10 minutes, then plug it back in. Reboot one computer first and wait until it's fully rebooted. Turn on the second one untill all computers are fully booted up.

If same problem occur, then you need to contact IOGEAR and have them RMA the device.

Thank you and good luck!

When 2 pcs boot at the same time on my GSC1464 switch, the one which the swtich's tune too work the video display like it should but the second limit the second computer (the one who wasn't selected) limit...

When a computer first boots up the video card send a request to the monitor to find on what resolutions the monitor supports. If the video does not get a response the card will default to very low resolutions. The only way to avoid this problem is to boot your computers one at time and keep the KVM on the computer until it fully boots to a desktop. This will allow the KVM to pass the monitor information to the computer.

Laptop will not connect properly

If possible directly connect the KVM cables to the laptop computer. Try to avoid connecting the KVM cables to a docking station. Also if your KVM has manual port selection buttons on the front of the KVM try holding that button for about five seconds when switching ports.

Need drivers for xp and vista

Most KVM switches does not have a driver. Because these devices are simply Plug-n-Play and does not require any driver installation.

What you need to do is to check the system requirements for every KVM switches before purchasing it.

Here's the fact:
- PS/2 KVM switches are designed for PS/2 computers keyboard and mouse

- USB KVM switches are designed to work with USB. Meaning, if you're going to use an adapter (PS/2 to USB), there's a big chance that your KVM might not work correctly.

- Most KVM switches does not work properly with docking stations.

- KVM switches are tested to work with wired keyboards and mice.

- You have to make sure that everything is properly connected to the computers if you want your KVM switch function properly.

- Lastly, update the USB driver of your computers (XP and Vista).

- Most KVMs has a firmware upgrade that you may find in manufacturer's Web site.

Keybrd quits working on laptop after ctl-alt_del to reach login

Repeating keys? This is a common problem for KVM switches if you go beyond the devices' capability. As you can see, GCS62 is a PS/2 KVM switch and it was designed to work only using a regular PS/2 keyboard.

This KVM switch does not support PS/2 to USB adapter. It might work but it's not guaranteed to work correctly. This does not work properly if you have a docking station for the laptop. It might work for couple of months then it would stop.

You smay isolate the problem by following the steps below:

1. Connect the keyboard directly to the computer to see if you will get the same problem.

2. Power cycle the KVM switch by disconnecting it from the computers and leave it unplugged for a minute or two.

3. Avoid using hybrid connection (PS/2 converted to USB) only for testing purposes.

4. If that work, then you know the answer is that this KVM only designed an work correctly with native PS/2 connection.

Belkin (F1DK102P) 2-port KVM Switch freezes

We have the same model and the same problem. The scroll lock combo did not work for us. You need to press Ctrl, Ctrl then up or down arrow.

The manual was a load of old Tom *** as it did not mention this.

Not running on startup

I occasionally have a similar problem with a couple of my KVM?s and I think it relates to the circuitry in the KVM that is supposed to fool the PC into thinking a mouse/keyboard is attached. Windows doesn?t see the mouse so it doesn?t load the drivers unless you force it. What works for me is to just start the PC and switch the KVM to that PCs port and leave it there till the computer finishes booting. Then its safe to switch to the other port, probably not the elegant solution you were looking for but it works every time.
