Important!

This product requires a Gigabit switch that supports 8k jumbo frames in order for multicast mode to function correctly. If the LAN is not exclusively dedicated to this product, then a managed switch is highly recommended.

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 first 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 configured 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).

  1. Repeat steps 1 - 5 for each Sender and Receiver to be changed.

For example, in Figure 2.1, let's say we are currently connected to the Web interface 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.

Switching between Sender units in Unicast mode

When multiple Sender and Receiver unit are used in unicast mode, the HD over IP w/ RS-232 and 2-way IR behaves as a switcher. In unicast mode, a Sender unit can communicate with only one Receiver unit at a time.

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 just over 65,000 Sender and Receiver units, depending upon the network bandwidth and the number of ports on your network switch.

Gefen EXT-HD2IRS-LAN-RX - Switching between Sender units in Unicast mode - 4

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 first.

Configuring Multicast Mode

The term multicast is used to describe a configuration 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.

Gefen EXT-HD2IRS-LAN-RX - Tip - 5

Important!

When switching between unicast and multicast modes, both Sender and Receiver units need to be configured identically.

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.
