specifications is required :
[S1] Optional mask setting
Optional masks available with GMS300 series units can be set by selecting
short posts.
1. Setting of K-input and R-Port for STOP release
Shorting the KSR0 ~ KSR3 and RSR0 ~ RSR3 with the side of H can set the
STOP releasing function by the corresponding KSR0 ~ KSR3 and RSR0 ~
RSR3. If no STOP releasing function is desired, short them with the side of L.
