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.
- 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

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.
- 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.
- 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).

- To display the source image, once again, reconnect the HDMI cable to the HDMI In port on the Sender unit.
Login Procedure
Each Sender and Receiver uses a built-in Web interface which is used to assign settings and control the features of each unit. The Web interface features a login screen which provides two access types: Administrator login provides access to all features and settings. Operator login limits access to channel switching and video modes.
- Access the Web interface by entering the IP address of the Sender or Receiver unit in the address bar of a Web browser. Refer to Displaying the IP Address (page 16) if necessary.
- The Login tab will be displayed in the Web interface.

- Click the arrow next to the Username field.
- Two user names will be displayed: Administrator and User.

- For this example, select the User name.
- Enter the password in the Password field. By default, the password for the User login is user. The default password for the Administrator login is admin. Note that these passwords are case-sensitive.

- Click the Login button.
- The Network tab will appear, just to the right of the Login tab.

If the Administrator login is used, additional tabs will be displayed:

Viewing System Settings
The Login screen displays the current version of firmware, network mode, and IP addresses.
- Access the Web interface for the Sender or Receiver unit. The password must be set for each Sender and Receiver unit.
- The Login tab will be highlighted.
- Locate the Firmware version and System settings sections, as shown below.
Firmware version
kernel version: A5.11 webfwh version: V1.35hs
System settings
Network Mode: Unicast Mode
IP Mode: autoip
IP Address: 169.254.6.204
Subnet Mask: 255.255.0.0
Default Gateway: 169.254.0.254

Information
The firmware version can also be found under the System tab, when logging in as Administrator.
Setting the Password
Both the User and Administrator passwords can be changed. Each Sender and Receiver unit can have a different password, if desired. To prevent unauthorized tampering of configuration settings, it is highly recommended that the Administrator password be changed as soon as each unit is configured. Passwords are case-sensitive.
The default password for Administrator is admin. The default password for User is user.
- Access the Web interface for the Sender and Receiver unit. The password must be set for each Sender and Receiver unit.
- Log in as Administrator.
- Click the System tab.
- Enter the new password for the desired user name(s). In the example, below, both the Administrator and User passwords are being changed.

- Click the Change button under the appropriate user name.
- The following message will be displayed, at the top of the page:

Success: New Password applied.
- Return to the Login tab and login as with the new password. This step will terminate the current session (using the old password), allowing the new password to take effect.
Setting the Video Channel
In order for Sender and Receiver units to communicate with one another, they must both be set to the same video channel. This is similar to changing the channel on a cable or satellite box in order to view a different program. By default, all Sender and Receiver units are set to channel 0.

Information
When connecting Sender and Receiver units, it is highly recommend that the video channel for each unit is set to a channel other than 0. This will allow for the addition of future Sender and/or Receiver units without causing video channel conflicts.
- Access the Web interface by entering the IP address of the desired Sender or Receiver unit in the address bar of a Web browser. Refer to Displaying the IP Address (page 20) if necessary.
- Log in as Administrator or User.
- Click the Network tab. The current channel is displayed within the Network Mode window group.
- Click the Channel Selection drop-down list and select the desired channel. Channel numbers can range from 0 to 255.

- Click the Save button on the right-hand side of Network Mode window group.

- The following message will be displayed, at the top of the page, indicating that the casting mode has been applied to the Sender or Receiver unit.
i Success: New casting mode applied.
- 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.

- Click the desired video mode button under the Picture Quality Mode window group. The select button will turn blue.
- The following message will be displayed, at the top of the page:
The HD over IP w/ RS-232 and 2-way IR 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 Identification 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 EDID
- Access the Web interface for the Sender unit.
- Login as Administrator.
- Click the Functions tab.
- Click the Load Internal EDID button.

- 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.

-
Click the Reboot button at the bottom of the page.
-
The Sender unit will now use the EDID of the downstream sink device.
Configuring Unicast Mode
The term unicast is used to describe a configuration 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.

Information
The Sender and Receiver units are 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. The red lines represent the video signal.

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.

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.

- Repeat the steps above in order to configure the Sender unit to multicast mode.

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.

Warning!
The following procedure will reset a Sender or Receiver unit to factory-default settings. All current configuration information will be lost.
- Disconnect the power from the unit.

- Press and hold the Reset button using the end of a paperclip or other sharp pointed object.
- While depressing the Reset button, reconnect the power.
- The Power LED indicator will begin to flash.
- Wait until both the Power and Link LED indicators begin to alternately flash.

- Release the Reset button.
- Disconnect the power once again, then reconnect the power.
- The unit is now reset to factory-default settings.
- Repeat the above process for each Sender / Receiver unit.
The Sender and Receiver units can be mounted on any flat surface, as shown below (screws not included). There should be an inch or two of clearance between the edges of the unit and any walls or vertical surfaces to allow for enough clearance for connection and disconnection of the HDMI cables.
For installation on a drywall surface, use a #6 drywall screw. When installing, it is recommended to use the center hole on a stud.
