Upgrade Fail

If you don’t see “Firmware upgrade OK” in the “Status Messages” window, it means the utility has failed to

complete the rmware successfully. If that occurs, please do the following:

Step 1

Unplug the DC connector from the KVM,

then remove the housing of the KVM.

Step 2

Using a jumper cap, short the jumper on the

main board labeled J40 (for GCS1642) / J45

(for GCS1644).

Step 3

Now plug the DC connector back into the

DC jack from the KVM. This will restore the

KVM with factory default rmware.
