Frequently Asked Questions - EXT-3G-HD-C Gefen
What is the Gefen EXT-3G-HD-C used for?
The EXT-3G-HD-C is a compact audio/video converter that transforms 3G-SDI, HD-SDI, or SD-SDI video signals with embedded audio into HDMI for connection to monitors, projectors, or TVs. It also features a loop output to feed another SDI device.
Does the converter support audio?
Yes, it extracts embedded audio from the SDI signal and passes it through the HDMI output. Up to 8 channels of PCM audio is supported depending on the source.
What video resolutions are supported?
It supports SD (480i/576i), HD (720p, 1080i), and Full HD 1080p at 60 frames per second, as well as various 3G-SDI data rates up to 2.97 Gbps.
Can I power the converter from my computer?
Yes, it accepts 5V DC power via a USB cable. You can plug it into a standard USB port or use the included adapter.
How do I connect the converter to my setup?
Connect your SDI source (e.g., camera) to the SDI input using a BNC cable. Connect an HDMI cable from the converter to your display. If needed, connect another SDI device to the loop output. Finally, power on the unit.
Why is there no picture on the HDMI display?
Check that a valid SDI signal is present (the green LED should be on). Verify the HDMI cable is firmly connected and the display is switched to the correct input. Ensure the source format is one of the supported SDI standards.
What is the loop output for?
The loop output is a second SDI output that mirrors the input signal. This lets you connect the same SDI source to another device, like a second monitor or recording unit, without using a splitter.
Can I use this converter with a 4K source?
No, the EXT-3G-HD-C is designed for 3G-SDI signals up to 1080p only. It does not support 4K/UHD formats.
How do I clean and maintain the device?
Use a dry, lint-free cloth to gently clean the enclosure. Do not use liquids, aerosol sprays, or harsh chemicals. Keep the unit away from dust and moisture when not in use.
Are any parts user replaceable?
No, the converter has a sealed metal enclosure. There are no user-serviceable parts. If the unit fails, contact qualified service personnel or your dealer for repair.
