Daisy chain blackmagic Quad SDI input card

Postby koenv » Mon Jul 28, 2014 12:45 pm

For a project we will use 2 Blackmagic Quad HD-SDI cards in our servers.

The Quad SDI have a in- and output for the four SDI channels.
Is the input also given on the output when using with Pandoras Box software?
Does anyone knows of I can daisy chain the two cards?

Example: Input card 1 = Output card 1 ---> Input Card 2

I have daisy chained the input to the Out/Thru on the card when I was short an SDI DA... it does work.

I am not sure if it adds any delay or not.

Also, you should keep in mind, these are "active" outputs - meaning that if you remove the input from your project, the output goes black. Also, if anything crashes or shuts off for any reason, your output will also stop working.
Lose the first one in the chain, lose them all..
This is why I prefer to use either an SDI DA or an SDI Matrix.
