Troubleshooting
Ensure that all cables are well seated. Check that keyboard/mouse cables are not
swapped. Label and bundle the cables for each computer to avoid confusion when
connected to the DIGITUS®.

Push the assembled drawer and the KVM
Module box firmly together leaving only
8mm (5/16 inch) space in between. Be
sure they are secured by two screws.

but keyboard and touch
pad does not work.

Connection
inside
the
KVM drawer
becomes
loose due to vibration.
If the C-36 connector on the KVM Module
box connects to a KVM drawer, its
Local
console should not connect to any
keyboard or mouse.
Verify if the KVM drawer is bad by
disconnecting it from the KVM Module
box
(the
C-36
connector
is
not
connected). Connect
a keyboard,
mouse, and monitor to the

port on

ports and use
the KVM Module box as a stand-alone
KVM Switch.
