The HD over IP w/ RS-232 and 2-way IR Sender and Receiver units can either be
connected over a Local Area Network (LAN) or they can be directly connected to one
another.
Using a Direct Connection
By default, Sender and Receiver units are 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 used only when Sender and Receiver units are directly
connected to one another. When connecting to a network, the Sender and Receiver units
must be set to either DHCP or Static IP mode. See Setting the IP Mode (page 22) for
more information .
1. Connect a CAT-5e (or better) cable from the LAN port on the Sender unit to the
LAN port on the Receiver unit. The cable should not exceed 330 feet (100 meters)
in length.

Local Area Network (LAN) Connection
In order to connect the HD over IP w/ RS-232 and 2-way IR to a Local Area Network (LAN),
both the Sender and Receiver unit must rst be set to DHCP 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. Connect an Ethernet cable from the LAN port on both the Sender and Receiver unit
directly to the router. Each cable that is connected to the router should not exceed
330 feet (100 meters) in length.
2. Access the Web interface for the Sender unit by entering its IP address in the address
bar of the Web browser. If the IP address is not known, see Displaying the IP Address
(page 7).

of Receiver unit R1. The numbers in blue represent the video channel that has been
assigned to each Sender and Receiver unit. Receiver unit R1 is set to video channel 4.
Sender unit S2 is also set to video channel 4. Therefore, we are only able to view the
source that is connected to Sender unit S2.
If we wanted to view the source that is connected to Sender unit S3, then we would
change Receiver unit R1 from channel 4 to channel 3.

Configuring 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 HD over IP w/ RS-232 and 2-way IR functions
similar to an HDMI switcher.
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. The red lines represent the video signal.
Figure 2.4 - Unicast mode: A Sender unit can communicate with only one Receiver
unit at a time.
1. Access the Web interface by entering the IP address of the Sender or Receiver unit
in a Web browser. Refer to Displaying the IP Address (page 30), if necessary.
In this example, we will start with Receiver unit R1.

Unicast and Multicast Modes
In order to solve the problem, in Figure 2.7, 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 HD over IP w/ RS-232 and 2-way IR 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.
Information
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.

Unicast and Multicast Modes
Configuring 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 HD over IP w/ RS-232 and 2-way IR functions similar to an HDMI
matrix.
The following illustration shows three Sender units (S1, S2, and S3) and two Receiver units
(R1 and R2) on a network, operating in multicast mode. Sender unit S2 is transmitting the
video signal to Receiver units R1 and R2. The video channels are shown in blue. The
video signals are shown in red.

The HD over IP w/ RS-232 and 2-way IR 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, a display is connected to Receiver unit R1. This is the RS-232 client.
We want to control this product from Sender unit S3, using an automation device (host).
The channel numbers are listed in blue. The RS-232 data is shown in orange. The video
signals have been removed, from the diagram, for clarity.
