Power LED: Solid light indicates the device is properly powered.
Status LED: Flashing light means the device is operational and ready for use.
HDCP LED: Solid light indicates HDCP content is active.
Link LED: Solid light indicates a stable connection between the Transmitter and Receiver.
Try Different Cables: If issues persist, try using different CAT and HDMI cables to rule out cable-related problems.
Cat Cable Categories: Ensure you are using the correct category (e.g., Cat 6, Cat 6a, Cat 7). Using the right cable prevents signal loss and maintains performance over long distances.
HDMI Certification: Use certified 4K HDMI cables. Non-certified cables may cause flickering, poor performance, or intermittent connections.
Refer to the specifications page to confirm which power option applies to your device. These are all power options available:
1-Way PoH: Power goes in only one direction (e.g., TX powers RX or RX powers TX).
2-Way PoH: Power can be supplied in either direction (TX to RX or RX to TX).
Separate Power: In some cases, power needs to be applied to both the TX and RX units separately.
Source Devices: Let us know which source device you are using, along with its resolution and refresh rate. This helps us troubleshoot compatibility issues.
Display Model: Verify the model number of your display (e.g., TV, projector). This helps us troubleshoot compatibility issues.
To rule out complex issues, start with a simple test:
Set the laptop as the input device and configure the resolution to 1080p60.
Use a short, tested LAN cable (1-2 meters) to connect the TX and RX units.
Connect a regular TV or display as the output device (1080p or 4K).
Check if the image appears on the display.
Below is an example of a quick test connection diagram.
Cable Specifications: Verify the HDMI and CAT cable specifications for your device. To find your device specifications, visit the main . For example, below are the characteristics of the EX-35-H2.
