Frequently Asked Questions - HI0378SDI HELGI

How do I connect the SDI extender?

Connect the SDI source (e.g., camera) to the TX unit's SDI input, run a single mode optical fiber cable from TX to RX, then connect the RX SDI output to your display. Power both units with the included DC5V adapters.

What does "waiting for connection" mean on the TV?

This indicates no link between TX and RX. Check that both units are powered on and the fiber optic cable is properly connected.

Why does the TV show "HDBitT Reminder: Please check the TX input signal"?

This means the TX unit is not receiving a valid SDI signal. Verify the source device is outputting SDI, and try connecting it directly to the display to confirm the source works. Also check the SDI cable.

How far can I transmit the SDI signal?

Using single mode optical fiber, the extender can transmit 1080p signals up to 20 km (12.4 miles).

Can I use the IR remote control through the extender?

Yes, the extender supports IR pass back. Connect the IR blaster to the TX and the IR receiver to the RX to control the source device remotely.

What power supply is required?

Each unit requires a DC 5V/2A power adapter. Only use the supplied adapters or ones with identical specifications to avoid damage.

Is the extender compatible with all SDI cameras?

It supports SD-SDI (270 Mbps), HD-SDI (1.485 Gbps), and 3G-SDI (2.97 Gbps), making it compatible with most standard SDI sources.

What if the display is not stable or fluent?

Try pressing the reset button on the TX or RX unit, or cycle the power. Also ensure the fiber cable is not bent or damaged.

Can I use multimode fiber?

The extender is designed for single mode optical fiber. Using multimode may drastically reduce distance and performance.

How do I clean the device?

Unplug the power and wipe the exterior with a dry, soft cloth. Do not use any liquids or solvents.
