‡ Reference mark uni-directional operation
The RGH41 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’).
