Operating Notes
• The Gefen Syner-G Software Suite is a free downloadable application from Gefen
that provides network conguration assistance and automatic download and
installation rmware upgrades for this product. Always make sure that the DVI KVM
over IP is running the latest rmware.
• The DVI KVM over IP is compatible with the HD KVM over IP, DVI KVM over IP w/
Local DVI Output, VGA KVM over IP, and the HD over IP w/ RS-232 and 2-way IR
which allows these products to be connected within a single system.
• Gefen highly recommends the use of the Syner-G software and Matrix Controller

The DVI KVM over IP Sender and Receiver units can be connected over a Local Area
Network (LAN) or they can be directly connected to one another. We will cover both
installations.
Getting Started
Local Area Network (LAN) Connection
In order to connect the DVI KVM over IP to a Local Area Network (LAN), both the Sender
and Receiver unit must rst be set to DHCP mode or Static IP mode. DHCP mode will use
the DHCP server to automatically assign an IP address for each Sender and Receiver unit
that is connected to the network. Static IP mode will allow the IP address for each Sender
and Receiver unit to be congured manually. Contact your network administrator if
necessary.
1. Use the included HDMI cable to connect the Hi-Def source to the HDMI In port on the
Sender unit.
2. Connect an HDMI cable from the Hi-Def display to the HDMI Out port on the Receiver
unit.
3. Connect a shielded CAT-5e (or better) cable from the Link port on the Sender unit
to the network.
4. Connect a shielded CAT-5e (or better) cable from one of the Ethernet ports on the
Receiver unit to the network.
5. Connect the included 5V DC locking power supplies to both the Sender unit and
Receiver unit. Do not overtighten the locking connectors. Connect the included AC
power cords from the power supplies to available electrical outlets.

DVI KVM over IP
2 Basic Operation
Setting the Video Channel
In order a Sender and Receiver unit to communicate with one another, they must both be
set to the same video channel. This is similar to changing the channel on a set-top box in
order to view a different program. Pressing and releasing the Switch button on the front
of the Receiver unit can also be used to change the video channel. We will cover both
methods in this section. By default, all Sender and Receiver units are set to channel 0.
Basic OperationBasic Operation
Setting the Channel using the Web Interface
1. Access the Web interface by entering the IP address of the desired Sender or
Receiver unit.
2. Login as “Administrator” or “User”.
3. Click the Network tab. The current channel is displayed within the Channel Setup
window group.
4. Click the Channel Selection drop-down list and select the desired channel.
Channel numbers can range from 0 to 255.
5. Click the Save button on the right-hand side of Channel Setup window group.
