4. Setup and Installation
4.1. Transmitter Interface
Familiarize yourself with the ports and indicators on the Transmitter unit:
- DC/5V: Power Input Port.
- Reset: Button to reset the device.
- IR TX: IR Transmitter Port for sending IR signals to the source device.
- HDMI Input: Connect your HDMI source device here.
- Status: LED indicator for signal status.
- Power: LED indicator for power status.
- Ethernet: RJ45 port for Cat5e/6 cable connection to the network switch or receiver.
4.2. Connection Modes
The J-Tech Digital HDMI Extender system supports various connection modes:
4.2.1. One-to-One Connection
In a point-to-point setup, a single Transmitter connects directly to a single Receiver via a Cat5e/6 cable. This extends the HDMI signal from one source to one display.
4.2.2. Many-to-Many Connection (Matrix Setup)
For more complex installations, multiple Transmitters and Receivers can be connected through one or more Gigabit Ethernet switches to create a flexible HDMI matrix. This allows any source to be routed to any display, or multiple displays simultaneously.
4.3. Basic Installation Steps
- Connect your HDMI source (e.g., Blu-Ray Player, Gaming Console) to the HDMI Input port of the Transmitter unit using an HDMI cable.
- Connect a Cat5e/6 Ethernet cable from the Ethernet port of the Transmitter to a Gigabit Ethernet switch (for matrix setup) or directly to a Receiver unit (for point-to-point).
- If using a matrix setup, connect Receiver units to the same or cascaded Gigabit Ethernet switches using Cat5e/6 cables.
- Connect your HDMI display (e.g., Monitor, Projector, Television) to the HDMI Output port of each Receiver unit using an HDMI cable.
- Connect the provided power adapters to all Transmitter and Receiver units, then plug them into a power outlet.
- For IR control, connect the IR TX cable to the Transmitter unit and position the IR emitter near the IR sensor of your source device.
5. Operating Instructions
5.1. Matrix Switching via Web Interface
When using the J-Tech Digital ProAV Unlimited HDMI Extender system with a compatible Gigabit Ethernet switch, you can manage input-to-output routing via a web-based interface. Connect a computer to the same network as the switch to access its configuration menu.
5.2. Android App Control
An Android application is available for convenient control of the matrix switching functionality. Search for "J-Tech Digital Matrix" on Google Play to download and install the app. This allows for intuitive management of your HDMI sources and displays from a mobile device.
