Novice yet complicated 002r sync question

[darkroom]

Howdy,

I am brand new to pro tools, DAWs, and Apples. I just started playing around with a new iMac G5 1.8, 002r w/6.4 LE. I am trying to dump Tascam DA78 DTRS tracks into pro tools, I have had some success.

My set-up:

MOTU Digital Timepiece (DTP) is the clock master
DA78 is synched to DTP via Tascam sync connector
MOTU 2408(the ancient original version) is connected via word clock to the DTP
MOTU 2408 is in standalone mode to convert DA78 tracks into ADAT format.
MOTU 2408 ADAT optical out is connected to 002r optical in
Pro Tools clock is set to internal RCA/S/PDIF, ADAT/optical

This seems to work so far.

In the future I may try to use the MOTU 2408 as 8 additional analog inputs via the ADAT lightpipe to the 002r. I want to make sure I have the best sync possible.

The DTP has a S/PDIF sync output, for slaving S/PDIF devices (It also has a digidesign superclock output, but the 002r seems to have no way to use the superclock without a bnc connector).

Is there any reason why I should or should not connect the S/PDIF output of the DTP to the S/PDIF input of the 002r when Pro Tool is in internal ADAT/RCA SPDIF mode? Will the 002r use the clock signal coming in the S/PDIF jack?

Thanks,
