Installation and Application
The system supports two main configurations:





- Point-to-point: Connect the HDMI source to the Transmitter, use a CAT5e/6 cable to connect the Transmitter to the Receiver, and connect the Receiver to the display.
- Matrix configuration: Connect multiple transmitters and receivers to an IGMP Gigabit Ethernet switch. The system supports a maximum of 256 combined units, limited to 100 transmitter units.
Network Configuration
The default IP addresses are 192.168.1.238 for the Transmitter and 192.168.1.239 for the Receiver. If your network has DHCP enabled, the units will be assigned IP addresses automatically. To reset to default IP addresses, disconnect the unit from the network, press the Reset button, and power cycle the device.
Computer Control
The HDBitT E-Matrix Control Center application (Windows only) allows for advanced management. Download it from www.hdbitt.com/download-matrix. Connect your computer to the network, ensure it is on the same subnet as the TX/RX units, and open the application to scan for devices, set IP addresses, change device names, and manage operating modes.

IR and Device ID Control
Use the included remote control to set or select the TX ID on the transmitter and the TX Connected ID on the receiver for device pairing. You can also use the buttons on the device to change the Device ID and Connection ID to the desired number.
Wireless Control
You can use the "Matrix Control Lite" app for Android or Apple to manage the system. Ensure a wireless router/access point is connected to the dedicated LAN, log in, and scan for TX and RX units.
