Introduction
The J-Tech Digital JTDHDEX1x4 is an HDMI extender and splitter unit designed to transmit a 1080P 60Hz HDMI audio/video signal over long distances using a single Cat5e/6 Ethernet cable. This system features one HDMI input and four HDMI outputs, allowing a single source to be displayed on up to four separate screens. Additionally, a local HDMI loop-out port on the transmitter enables connection of a fifth display for convenient source monitoring. The unit incorporates Power over Cable (PoC) functionality, meaning only the transmitter requires a power adapter, simplifying installation by powering the receivers via the connected Ethernet cable. It also supports IR control for remote management of the source device and includes an EDID toggle switch for optimal audio format compatibility. This plug-and-play device is suitable for various commercial and residential environments.

Setup & Installation
Follow these steps to set up your JTDHDEX1x4 HDMI Extender Splitter:
- Power the Transmitter: Connect the included 12V DC power adapter to the 'DC/12V' port on the transmitter unit and plug it into a power outlet. The transmitter will power on.
- Connect HDMI Source: Connect your HDMI source device (e.g., Roku, Blu-ray player, laptop) to the 'HDMI In' port on the transmitter using an HDMI cable.
- Connect Ethernet Cables: Connect Cat5e/6 Ethernet cables from the 'Cat Out' ports (Cat out1, Cat out2, Cat out3, Cat out4) on the transmitter to the 'Cat5e/6 Input' port on each of the four receiver units. For optimal performance, use high-quality J-Tech Digital Cat5e or Cat6 Ethernet cables.
- Connect Displays: Connect each receiver unit to its respective display (TV, monitor) using an HDMI cable from the 'HDMI Out' port on the receiver to the HDMI input on the display.
- Local HDMI Loop-out (Optional): If you wish to monitor the source locally, connect an additional HDMI cable from the 'HDMI Out' port on the transmitter to a local display.
- IR Control Setup (Optional):
- Connect the IR TX cable (emitter) to the 'IR Out' port on the transmitter. Position the IR emitter head near the IR sensor of your HDMI source device.
- Connect the IR RX cables (receivers) to the 'IR-RX' port on each receiver unit. Position the IR receiver head in a location where it can receive signals from your remote control.
- Power On Devices: Ensure all connected displays and the HDMI source device are powered on. The system is plug-and-play and should automatically detect and display the signal.

Operating Instructions
EDID Switch
The transmitter unit features an EDID (Extended Display Identification Data) toggle switch. This switch allows you to select the preferred audio format to ensure compatibility with your connected displays and audio systems. The available settings are typically 2.0 (for stereo audio) and 5.1 (for surround sound audio). Adjust this switch if you experience audio issues or require a specific audio format.
IR Control
The IR control feature allows you to control your HDMI source device (e.g., cable box, DVD player) from the location of any of your remote displays. Ensure the IR TX cable is correctly positioned near the source's IR sensor and the IR RX cables are positioned on the receivers to pick up signals from your remote control. The IR control is one-way, transmitting commands from the display location back to the source.

Troubleshooting & FAQ
Common Questions
- Q: Can this product extend 4K signals?
A: No, this model is specifically designed to extend 1080P@60Hz signals and does not support 4K signal extension. - Q: Is IR control bi-directional?
A: No, the IR control feature is one-way. It allows you to control the HDMI source from the display location, but not vice-versa. - Q: Does this product support multi-resolution output?
A: No, this device does not support multi-resolution output. To ensure compatibility and proper functionality, all devices in your setup (source and displays) should support the same resolution.
General Troubleshooting Tips
- No Video/Audio: Ensure all cables (HDMI, Ethernet, power) are securely connected. Verify that the HDMI source and all displays are powered on and set to the correct input. Check the EDID switch setting for audio compatibility.
- Poor Picture Quality: Ensure you are using Cat5e or Cat6 cables of appropriate length and quality. Longer cable runs or lower quality cables can affect signal integrity.
- IR Control Not Working: Check that the IR TX emitter is correctly positioned over the source device's IR sensor and the IR RX receiver is in a clear line of sight for your remote control.
- Intermittent Signal: This can sometimes be resolved by ensuring all devices are set to the same native resolution. Power cycling all components (source, extender, displays) may also help.
