greetings! i'm trying to add a 2nd dtc to my system. i *believe* i have properly informed my 918 (running 5.0) of the new dtc's presence and have gotten the ethernet cabling right. BUT when i take the system down and bring it back up - dtc #1 (oh - they're both 48's) does a rotating flash of 64 & 65 and dtc #2 does a rotating flash of 63, 64 & 65. obviously, somethings not right (duh :-). if i unplugged the 2nd dtc from the 't' on the back of the first dtc, dtc #1 will (in it's ever so leisurely fashion <sigh>) sync-up with the system and everything is hunky-dory. any ideas? tia - donna btw - guess a picture might be helpful... 918-------T--#1 ('T' = t-connector on the back of the dtc) | (----- & | = ethernet cables) | | #2
