5.1 Multi-Receiver Application (via Ethernet Switch)
This extender supports a one-to-many configuration using an Ethernet switch. To achieve this, connect the HDMI Transmitter to an Ethernet switch, and then connect multiple HDMI Receivers to the same Ethernet switch. Each Receiver will then connect to its respective display.
Image: Diagram showing the J-Tech Digital HDMI Extender in a multi-receiver setup. A laptop (source) connects to the Transmitter, which then connects to an Ethernet switch. Multiple Receiver units are connected to the switch, each feeding a separate display, extending the signal up to 400ft.
6. Arahan Operasi
Once the setup is complete, the extender operates automatically. Ensure all devices are powered on in the correct sequence (source, then extender units, then display) for optimal performance.
6.1 IR Control Functionality
The IR extension feature allows you to control your HDMI source device from the location of your display. Point your remote control at the IR Receiver head connected to the Receiver unit. The signal will be transmitted through the Cat cable to the IR Emitter head connected to the Transmitter unit, which then relays the command to your source device.

7. Penyelenggaraan
- Clean the unit with a soft, dry cloth. Do not use liquid or aerosol cleaners.
- Pastikan unit bebas daripada habuk dan serpihan untuk memastikan pengudaraan yang betul.
- Periksa sambungan kabel secara kerap untuk memastikan ia selamat.
