Quad HD split
Your Teranex Mini 12G SDI to Quad SDI converter has multiple ways of sending high bandwidth
image data over relatively low bandwidth connections.
This diagram represents the difference between quad link SDI, where image information is split
between four 3G-SDI cables to form a single Ultra HD image, and quadrant HD split, where
each of four HD screens receives one quarter of a complete image as part of a video wall.
Dual link 6G SDI operates in the same way as quad link, in that one complete signal is split
across multiple cables, except that only two 3G-SDI outputs are used.

Switches
Teranex Mini – 12G-SDI to Quad SDI’s switches provide the following settings:
Switches 8 & 7 – Quad SDI Output
Switches 8 and 7 are represented as bits 1 and 0, respectively. This simply means that by setting
various on off combinations of switches 8 and 7, you can choose how an 12G-SDI Ultra HD
signal is split among your Teranex Mini converter’s four outputs.
Below are some example configurations for converting an Ultra HD signal to quad link, dual link
or quad HD split mode.
If the input is 12G-SDI and switches 8 and 7 are set to ‘off’, the output will be interleaved
quad link.
If the input is 12G-SDI, switch 8 is set to ‘off’, and 7 is set to ‘on’, the output will be 4 HD
quadrants.
If the input is 6G-SDI, switch 8 is set to ‘on’ and switches 7 and 6 are set to ‘off’ the output will
be dual link 3G-SDI level B.
If the input is 6G-SDI, switch 8 is set to ‘on’, switch 7 is set to ‘off’ and switch 6 to ‘on’, the output
will be dual link 3G-SDI level A.
When the converter is in Quad HD split mode, the 4 outputs will carry 4 independent HD
quadrants to form the complete Ultra HD image.
