Can't connect my ADAT 24 Bridge to my Digi 003... Is this possible?

[RickT]

I'm trying to connect my ADAT 24 Bridge to my Digi 003 with the optical cables but not having any luck. I have an old Mac OS 9 machine running Pro Tools 5.1.

The Mac has two mix cards but the guy that set it up 20 years ago used a splitter cable (see pics) to just use mix card 1. The spitter cable then connects to both the ADAT 24's Computer A and Computer B connections.

When I try to connect the optical cables from the ADAT 24 to the Digi 003, nothing happens. Meaning I don't get any connection lights showing up on the 003 like I get when I have a firewire connected using my Windows PT 12 system. And I'm not even sure which optical cables go where. There are two ins and two outs on the ADAT and one in and one out on the 003.

My goal is to simply hear my old PT 5.1 recordings on the Mac OS 9 machine and find the things I like and try to convert them to my Windows PT 12 system. If I can't get the ADAT 24 to connect to the 003 is there another way to hear the recordings? Without the ADAT 24 connected PT 5.1 won't even load on the MAC.
