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.
