i noticed my lexicon mx3000 rack effect thingy has the spdif in/out on it. My creamware has those cables marked 'dig in' and 'dig out' and those are spdifs right? I never bothererd using them as i never really had anythng exiting to spdif but now i maybe do

So i wonder, can i use those dig in/out connectors on my pulsar 1 and save 2 ins and 2 outs on my second ada8200?
The powersampler also have a spdif in/out buts it som kind of funky connector (copied from soundonsound.com: "and an eighth‑inch mini‑jack for S/PDIF In/Out. This last connector does seem an odd choice, but has the advantage of only using a single socket to service both digital In and Out — a stereo 3.5mm jack to twin phono adaptor lead"
How does that cable even look? the phono-cable cant do the spdif thing although the plug fits yes?
I would really appreaciete if someone would enlighten me.
Thanks!
