I don't have any experience with these cards, but I'm setting up a GV900/8 I got that didn't come with the input cables. I've looked online for a few days and haven't been able to find any that say they support the GV900. Will a cable like this work, or does anyone know where I can find replacements?

This was annoying me because I didn't want to get the wrong cable. Thank you.
