1.2.2 Specifications 
 
The M222 incorporates the standard 40-pin, 20x2 row connector interfaces to the carrier board 
for power and data/control, but does not have the 24-pin optional connector for carrying user-
connections back onto the carrier board. 
The user input/output is provided through a standard 44-pin D-subminiature female receptacle. A 
mating connector kit can be ordered separately as AM111 (C&H Part Number 11029700-0001). 
CONEC part number 302A10889X (or equivalent) is used on the assembly. The connector pin-
outs are shown in Appendix A.
