Castle Caretech's info on Bus wiring.

is it a mini bus ?

LOL

To many variables in life,nothing is guaranteed,what may work in one circumstance doesn't mean it'll work in all-we all add information to the tapestry!,just because our findings suggest only one outcome doesn't necessarily mean only one outcome exists!.

Anyway the manufacturers stipulate data bus resistors so that's what we should be fitting.

conformist.

resistors on data are required as its a balanced line and the resistors terminate hat line and remove swf issues. however modern equipment deals with data errors so well on the line that imo they are rarely required. Plus on an electrically noisy line the resistor value is no constant. So as basic advice id say never fit them as std and do so if you have the odd site with data issues. all imho

I always do on Gals. The cooper/Texe stuff we sometimes fit doesnt require them

ill stick to my original comment...

Some manufacturers switch eol resistors in at eol automatically, hence some dont tell u to fit terminating resistors

on the data? auto termination, who does that then?
