What's the deal?

I have JC-102cua(2-port)I don't know what happened, but i am not able to switch over to the second PC for more than 2-3 seconds before it switches back to the 1st PC. I don't have my manual handy or i would read up on the troubleshootinbg section Oh, and yes, both PC's are up and running in case you are wondering. Thanks in advance, Kevin.

Re: What's the deal?

Is it possible that there is a problem with the button? Try wiping them down with a damp paper towel or blasting it with canned air. Also, most of the time KVM's have a keyboard shortcut that will change the input also, perhaps give that a try.

Belkin Flip PS/2 - KVM switch - 2 ports how do i switch from pc to pc on key board

The instruction below the link is for a 2 port version KVM, and may not apply to your particular model. You can look your model up here:

You can switch directly to any port by entering the Switch port number you wish
to use. For example, if you press “SCROLL LOCK”, “SCROLL LOCK”, “2”, the
computer on port 2 will be selected.

AutoScan Mode
In AutoScan mode, the Switch remains on one port for eight seconds before
switching to the next. This time interval cannot be changed.
To enable AutoScan mode, press “SCROLL LOCK”, “SCROLL LOCK”, “S”.

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.

Other information:
In AutoScan mode, the switch remains on one port for 10 seconds before switching to the next. This time interval cannot be changed. To exit autoscan mode press [Spacebar].

When in AutoScan mode, no mouse or keyboard controls. If the user moves the mouse or uses the keyboard while switching the connection between computer and the switch might be interrupted and cause erratic mouse movement and errant display when using the keyboard.

Maximum resolution supported is 2048 x 1536 @ 75Hz.

If mouse movement is erratic:
make sure you do not have more than one mosue driver installed. Make sure that the driver is either for a standar PS/2 mouse or a Microsoft compatible PS/2 mouse. Make sure you do not have any mouse drivers loaded in your CONFIG.SYS or AUTOEXEC.BAT files. Avoid moving the mouse or pressing the mouse button when switching ports on the switch. You can reset the mouse and resume porper mouse movement simply by unplugging the mouse from the switch and allowing 2-3 seconds before plugging it back in.
