Rulland Posted February 19, 2012 Posted February 19, 2012 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.

james.wilson Posted February 19, 2012 Posted February 19, 2012 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 securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.
9651 Posted March 1, 2012 Posted March 1, 2012 I always do on Gals. The cooper/Texe stuff we sometimes fit doesnt require them

fozzies Posted March 1, 2012 Posted March 1, 2012 Some manufacturers switch eol resistors in at eol automatically, hence some dont tell u to fit terminating resistors
james.wilson Posted March 2, 2012 Posted March 2, 2012 on the data? auto termination, who does that then? securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.
