NOTE:
Dual limit versions (A) utilise the clear wire (pin 7) as the V
P
limit output. The V
X
external set-up signal on these
versions is not available. Dual limit readheads are only available with F, L or X terminations.

‡
Reference mark uni-directional operation
The RGH22 reference mark output is not repeatable in both directions. Certain controllers will flag an error
when they see 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 the unphased
direction (see section Reference mark set-up).
