3GSDI to HDMI Converter

®

The Gefen EXT-3G-HD-C converts audio and video from SDI to HDMI 
format, at resolutions up to 1080p Full HD. 3G-SDI, single link HD-SDI, and 
audio formats up to 8 channels of LPCM are supported. This product is fully 
compatible with the Gefen Syner-G™ software suite. The Gefen Syner-G™ is 
a powerful set of software tools specifically designed to help discover, 
configure/customize, manage, monitor, and upgrade Gefen products. 
The Gefen EXT-3G-HD-C’s compact enclosure, while light enough to be 
held in place using double sided Velcro® tape, features an ISO standard 
1/4-20 attachment provision as well as a detachable surface-mounting 
bracket. This, along with a flexible power input circuitry capable of accepting 
a wide range of DC voltages and a locking power supply connector, make 
the EXT-3G-HD-C ideal for cutting edge mobile A/V applications as well as 
high performance fixed installations.

This product can be installed on camera gear via an industry-standard 
1/4-20 attachment thread located on the bottom of the unit. It can also be 
surface-mounted using the included surface mounting bracket. 
The EXT-3G-HD-C is light and compact enough to be held in place using 
Velcro® if your particular installation does not allow for the two preferred 
methods of installation described above. Set the DIP switches as necessary. 
Connect an SDI cable between the input of the EXT-3G-HD-C and an SDI 
source. Connect the HDMI output of the Gefen converter to an HDMI 
display or other downstream equipment using a Gefen locking HDMI cable. 
Connect the included 12V DC power supply to the 3GSDI to HDMI 
Converter’s power supply jack and to an available electrical outlet. 
To remove the power supply plug from the unit, disengage the lock by 
pulling back on its plastic sleeve. The power LED indicator will glow in blue 
to indicate that the unit is powered on. The HDMI Out LED indicator will 
glow in green to indicate that an active HDMI sink is present. Use the USB 
Mini-B port with Gefen Syner-G™ software suite for performing firmware 
updates. See the user manual for details.
