Hardware Installation and Configuration

Preparing Your Site

Note: The ST12MHDLNHK HDMI Over IP Extender Kit can use a 10/100 Ethernet LAN or Gigabit LAN Network (preferred) to extend the signal. The maximum supported distance between two Ethernet devices is 100 meters.
Note: Always use the included Universal Power Adapters.

Ensure the Transmitter and Receiver(s) are all situated near an available AC Electrical Outlet.

1.  Determine where the HDMI Enabled Video Source (e.g. computer, Blu-ray Player) will be located and set up the device.
2. Determine where the HDMI Enabled Display Device will be located and place or mount the display appropriately.
3. (Optional) If using additional Receivers (ST12MHDLNHR), determine where the HDMI Enabled Display Device(s) will be located and place or mount the displays appropriately.

5. Your source video images will now appear on the Video Displays connected to the Receivers.

IP Configuration

Note: The default IP address of each Transmitter and Receiver will be different.

Determine if DHCP is Supported and Enabled

Discovering whether or not your networking device supports DHCP, and ensuring DHCP is enabled, will determine your next steps when configuring your IP address. If your networking device supports DHCP, and DHCP is enabled, then your hub switch or router will assign an IP address automatically. If your networking device does not support DHCP, or DHCP is not enabled, then your Transmitter and Receiver(s) will default to the factory assigned static IP address.

To check if your computer has DHCP enabled complete the following steps:

Note: Depending on your operating system these instructions may vary.

1. Open your computer’s Control Panel.
2. Select View Network Connections.
3. Right-click on the network you intend to connect to and select Properties.
4. Navigate to Internet Protocol Version 4 (TCP/IPv4) and select Properties.
5. DHCP is enabled if the following two options are selected: Obtain an IP address automatically and Obtain DNS server address automatically.
6. DHCP is not enabled if you have configured your IP manually and the following options are selected: Use the following IP address and Use the following DNS server address.

You can now proceed to configure your IP address automatically or manually, depending upon your DHCP settings.

DHCP is Enabled on your Network Device

If you are using a hub, switch or wireless router that supports DHCP function, enable DHCP. The switch or wireless router will assign the IP address to the Transmitter and Receiver automatically.

Note: The Transmitter(s) and Receiver(s) that are being paired together must be on the same channel to communicate. Ensure the Rotary DIP Switch is set to the same channel on both the Transmitter and Receiver(s).

DHCP is not Enabled on your Network Device

If you are using a hub, switch or wireless router that does not support DHCP, then your Transmitter and Receiver(s) will default to the factory assigned static IP address. To change this IP address you will need to access the Web GUI through your web browser. You must first determine the factory assigned IP address. To do so, you must complete the hardware installation over a network device. By default, each Transmitter and Receiver will have an IP address in the range of 169.254.x.x. Your computer’s IP address and Subnet mask must be in the same range to communicate with the Transmitter and Receiver(s) and to become visible on your display. Complete the following steps to configure your computer:

1. Open your computer’s Control Panel.
2. Select View Network Connections.
3. Right-click on the network you are going to connect to and select Properties.
4. Navigate to Internet Protocol Version 4 (TCP/IPv4) and select Properties.
5. Change the IP address to 169.254.x.x (x=number between 0 and 255).
6. Change the Subnet mask to 255.255.0.0

The RX IP address displays the Receiver’s IP address. The TX IP address displays the Transmitter’s IP address. To access the Transmitter or Receiver for configuration complete the following:

1. Enter the TX IP address or RX IP address in the address bar of your web browser.
2. Use the default user ID: admin and password: 123456 to log into the GUI.
3. Scroll down to the Ethernet header and configure your IP address, Subnet mask, and Gateway to be in the same range for your Transmitter and Receiver(s).

Note: If you have changed your Transmitter and/or Receiver IP settings, configure your computer’s IP address, Subnet mask, and Gateway to be in the same range as the new settings for your Transmitter and Receiver in order to access the Web GUI.

Configure the IP Settings for Multiple Transmitters

In order to obtain the IP settings information for multiple Transmitters, configure your Transmitter and Receiver in a one-to-one setup over a LAN. The Rotary DIP Switch on the connected Transmitter and Receiver must be set in the same position or channel for the devices to communicate.

Infrared (IR) Blaster and Receiver Operation

Note: IR signals require direct line of sight communication between remote controls and receivers. Ensure your IR Remote Control is pointed directly at your IR Receiver. Also ensure your IR Blaster is pointing directly towards your Source Device’s IR receiver. Consult your Source Device’s user manual to find the exact location of the IR receiver.

• Direct IR Control of the Source Device at the Transmitter
  Connect the IR Receiver to the Control IR In / Extension IR Out Port on the Transmitter. Using the IR Remote Control, you can now control the HDMI over IP Transmitter.

• Direct IR Control of the Display Device at the Receiver
  Connect the IR Receiver to the Control IR In / Extension IR Out Port on the Receiver. Using the IR Remote Control, you can now control the HDMI over IP Receiver.

• IR Extension from Receiver to Transmitter
  Connect the IR Receiver to the Control IR In / Extension IR Out Port on the Receiver. Connect the IR Blaster to the Control IR In / Extension IR Out Port on the Transmitter. Using the IR Remote Control from your IR Enabled Target Device, situated on the Transmitter side, you can control the IR Device from the Receiver side.

IR Remote Control

Bandwidth Switch

This four-stage switch enables you to adjust the bandwidth of data that flows through the Transmitter. Toggle the Bandwidth Switch to the high “H” side when using a small number of Transmitters connected to high-definition HDMI Enabled Display Devices. Toggle the Bandwidth Switch to the low “L” side when using a large number of Transmitters connected to high-definition HDMI Enabled Display Devices. Toggle the switch to any of the settings between “H” and “L” to optimize your bandwidth, for optimal display performance when multiple Receivers are attached to one Source Device.

Resolution Switch

This two-stage switch enables you to adjust the resolution of all your HDMI Enabled Display Devices. Toggle the Resolution Switch to the right (the side displaying a small symbol) to enable 1080p resolution. Toggle the switch to the left to enable 720p resolution. Because this switch is located on the Transmitter the resolution will be adjusted for all of your Display Devices, at all the Receiver sites that have been paired with this Transmitter.

Serial Control

The Transmitter and Receivers can be controlled by direct Serial connection.

Note: Only one Transmitter or Receiver can be controlled at any given time.

To connect either the Transmitter or Receiver(s) to your computer, connect the DB9 to 2.5 mm Serial Adapter Cable to the Serial Port on your computer and the 2.5 mm connector to the Serial (Control) Port on the Transmitter or Receiver. To control the Transmitter or Receiver via Serial, use the following configuration and commands:
