OPT 8 Transfer Question

[zachattakk]

Hey there!
I'm trying to transfer files from the MDR to an interface that has ADAT optical inputs on it. I'm currently only using channels 1-16 on my MDR, so I could take out the 3rd analog card (channels 17-24) and install an OPT 8. Can I send tracks 1-8 and 9-16 to the OPT 8 that's in slot 3 (which would normally be channels 17-24) ?

Also, does anyone have an OPT 24 PCI card?

Thanks so much!
