Unicast and Multicast Modes

Conguring Unicast Mode

The term unicast is used to describe a conguration 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 with Local DVI Output
functions similiar to a DVI KVM switcher.

NOTE: The DVI KVM over IP with Local DVI Output 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.

Switching between Sender units in Unicast mode

When multiple Sender and Receiver units are used in unicast mode, the DVI KVM over

IP with Local DVI Output behaves as a switcher. In unicast mode, a Sender unit can
communicate with only one Receiver unit at a time.

In the example below, we will switch Receiver unit R1 to receive the DVI source on Sender
unit S1.

Operating the DVI KVM over IP with Local DVI Output

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 with Local DVI Output can be used with up to 256 Sender units

to provide switching capability between each Receiver unit.

Each Receiver unit can be set to receive video data from any one of the up to 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 with Local DVI Output

Unicast and Multicast Modes

Conguring Multicast Mode

The term multicast is used to describe a conguration 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 with Local DVI Output 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 with Local DVI Output

Using RS-232

The DVI KVM over IP with Local DVI Output 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 HD 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).

Operating the DVI KVM over IP with Local DVI Output

EDID Management

The DVI KVM over IP with Local DVI Output 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 Identication 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,
