Physically, the wires are daisy chained on the TPCs.  The DZ unit has 
db9 male/female you you insert it in-line in the serial cable coming 
from the Legacy.  But electrically, the wiring is parallel.  IE every 
device taps pins 2 and 5 in parallel.

I'll check out that thread on OGR.

Also, after I get all this running with Legacy, I'll post to the OGR 
forum with my experiences.


CU!
