The DVI KVM over IP Sender and Receiver units can either be connected over a Local
Area Network (LAN) or they can be directly connected to one another.
Page Title
Using a Direct Connection
By default, the DVI KVM over IP is shipped in Auto IP mode. In Auto IP mode, each
Sender and Receiver unit assigns itself a unique IP address within the range of
169.254.x.x. Auto IP mode is only used when Sender and Receiver units are directly
connected to one another. When connecting to a network, the DVI KVM over IP must be
set to DHCP mode or Static IP mode. See Setting the IP Mode for more information.
1. Connect a CAT-5e (or better) cable from the LAN port on the Sender unit to the
LAN 1 port on the Receiver unit.
Figure 1.1 - Directly connecting the Sender and Receiver unit
Sender unit
Receiver unit
Although any LAN port on the Receiver unit can be used, using the LAN 1 port makes
it easy to identify which Ethernet cable is used to connect the Sender and Receiver
unit. LAN 2 and LAN 3 ports can then be used for connecting additional devices or
when daisy-chaining Receiver units.

Unicast and Multicast Modes
Conguring Unicast Mode
The term unicast is used to describe a conguration where information is sent from one
point to another point. It is possible to have multiple Sender and Receiver units connected
in a system. However, in unicast mode a Sender unit can communicate with only one
Receiver unit at a time. In unicast mode, the DVI KVM over IP functions similiar to a DVI
KVM switcher.
NOTE: The DVI KVM over IP Sender and Receiver units shipped
from the factory in unicast mode.
The illustration, below, shows 3 Sender units (S1, S2, and S3) and 2 Receiver units
(R1 and R2) on a network, operating in unicast mode. The video channels are notated
in blue.

Note that each of the Sender units in Figure 2.3 is assigned a unique channel number.
However, if we were to change the video channel on Sender unit S1 to channel 1, this
would have violated the unicast mode rule: A Sender unit can communicate with only
one Receiver unit at a time.

Operating the DVI KVM over IP
Unicast and Multicast Modes
In order to solve the problem, in Figure 2.4, we would need to make sure that each of
the Sender units is set to a unique channel number.
When using unicast mode, each of the Sender units must be assigned a unique
channel and should never be changed. Use the Receiver unit to switch (channels)
between Sender units.
The DVI KVM over IP can be used with up to 256 Sender units to provide switching
capability between each Receiver unit. Up to 256 Receiver units are supported.
Each Receiver unit can be set to receive video data from any one of 256 Sender units.
NOTE: In unicast mode, if an additional Sender unit is introduced
into a system with the same channel as another Sender unit, then
the Receiver unit will continue to receive A/V data from the Sender
unit which was connected rst.

Operating the DVI KVM over IP
Unicast and Multicast Modes
Conguring Multicast Mode
The term multicast is used to describe a conguration where information is sent from one or
more points to a set of other points. For example, a single Sender unit can transmit data to
multiple Receiver units. In addition, if multiple Sender units are used, each Sender unit can
transmit data to any Receiver that is not already receiving data from another Sender unit.
In multicast mode, the DVI KVM over IP functions similar to a DVI KVM matrix.
The illustration, below, shows 3 Sender units (S1, S2, and S3) and 2 Receiver units
(R1 and R2) on a network, operating in multicast mode. The video channels are shown
in blue.

Operating the DVI KVM over IP
Using RS-232
The DVI KVM over IP supports RS-232 pass-through, allowing the control of remote
RS-232 devices. The Sender and Receiver unit which are being used to pass-through
the RS-232 data must be set to the same baud rate as the RS-232 host and client.
In the example below, the Gefen 4x1 DVI Switcher w/ Audio Decoding (Gefen part no.
GTV-AUDDEC-N) has been connected to Receiver unit A. This is the RS-232 client.
We want to control this product from Sender unit S3, using a laptop PC (RS-232 host).
The channel numbers are listed in blue.

Operating the DVI KVM over IP
EDID Management
The DVI KVM over IP features EDID Management. Before the source can send video
(and/or audio) data, the source device (connected to each Sender unit) reads the EDID
(Extended Display Identication Data) from the displays which are connected to each
Receiver unit. The EDID contains information about what type of audio/video data can
be sent by each source.
By default, the (downstream) EDID from the display, connected to the Receiver unit, is
used. However, under certain circumstances, it may be desirable to use the internal EDID
which is stored in the Sender unit.
Using the Internal DVI EDID
1. Access the Web interface for the Sender unit.
2. Click the Functions tab.
3. Click the Load Internal EDID button.
4. After a few moments, the following message will appear at the top of the page,
indicating that the new Serial over IP options have been applied.

Audio Connections
Audio works in both unicast and multicast modes. The only difference between the two
modes is that the Mic In jack is automatically disabled, on all Receiver units, in multicast
mode. To illustrate how audio works with the DVI KVM over IP, we will set up a microphone
and some speakers.
1. Our computer has a Line In jack, as part of the sound card and we want to be able to
access this jack from the Receiver unit. Therefore, connect the microphone to the
Mic In jack on the Receiver unit.
Connect to microphone
2. In order to get the audio from the microphone into the computer, connect a
3.5mm-to-3.5mm mini-stereo cable from the Line Out jack on the Sender unit to
the Line In jack on the computer.
WARNING: Do not connect the mini-stereo cable from the Line
Out jack on the Sender unit to the Mic In jack on the computer.
Doing so will result in audio “clipping” and may cause damage to
the computer’s sound card.

Using HDMI Sources
Hi-Def (HDMI) sources can be connected to the DVI KVM over IP when using HDMI-to-DVI
adapters on the Sender and Receiver units. HDMI audio is passed through to the DVI Out
port on the Receiver unit. The DVI KVM over IP will not pass content from HDCP sources
such as Blu-ray players and Playstation® console systems.
If a 3.5mm mini-stereo cable is connected to the Line In jack on the Sender unit, then the
HDMI audio will be disabled on the Receiver unit. The Line Out jack, on the Receiver unit,
will output audio from the source connected to the Line In jack on the Sender unit.
HDMI audio cannot be output using the Line Out jack on the Receiver unit.
