Operating Notes
• The DVI KVM over IP is compatible with the HD KVM over IP and the VGA KVM over
IP, which allows these products to be connected within a single system. Note that
HDCP content cannot be used when using these products in tandem.
• CAT-5 or CAT-6 cables should not exceed 330 feet (100 meters) between the
Sender / Receiver unit and the network.
• By default, all Sender and Receiver units are set to channel 0.
This product does not support HDCP or dual link resolutions.

• By default, the source device will use the EDID from the display (or other sink device)
which is connected the Receiver unit. See
