Using Your KVM Switch

Using the Pushbutton

Pressing the pushbutton on the front of the KVM switch allows you to scroll through your computers sequentially.

Using the Hotkey Commands

A keyboard hotkey sequence consists of three keystrokes. Each hotkey sequence starts with two Scroll Lock keystrokes. You must strike the Scroll Lock key twice in two seconds or less in order for the hotkey sequence to be acknowledged.

Command Hotkey Sequence Description
Select PC ScrLk + ScrLk + 1 (2, 3, 4)		Selects the PC plugged into Port 1 (2, 3, 4)

Troubleshooting

Keyboard/mouse problems

• You should have connected your keyboard, mouse, and monitor to the KVM switch before connecting the switch to your computer. If you reversed this process, try rebooting your PCs.
• Make sure the mouse/keyboard are properly connected to the KVM switch and that you have installed the proper drivers for your mouse/keyboard.
• Try rebooting your KVM switch by pressing ScrLk + ScrLk + End.
• If your keyboard/mouse came unplugged while in operation, you may need to reboot your PCs in order to get the switch to recognize your keyboard/mouse again.

Video problems

• If your screen won't show properly on your monitor, first make sure that all your cables are firmly seated in their proper ports.
• If your screen is coming up blank or striped, the resolution on your PC may be higher than the maximum resolution supported by the KVM (VGA 1920 x 1440). Adjust the screen resolution and frequency until they are in the supported range.
• If there is ghosting, speckles or stripes on your screen, there may be excessive electromagnetic interference from an external source. Check the path of your video cable for strong electromagnetic sources like motors or power cables. Try and keep your video cables as far as possible from these external sources.
