Reference mark uni-directional operation
The RGH40 reference mark output is repeatable for one direction of travel only.
Certain controllers will flag an error when they detect different reference mark positions in the forward
and reverse directions.
BID/DIR pins allow the readhead to be configured to ignore the reference pulse output in one direction
(see section ‘Reference mark set-up’).
