The JMACH1 connector provides the interface pins for channels 1 and 2. Usually, it is connected to a breakout board,
such as one of the Acc-8x family of boards or an application-specific interface board.
Note: 100-pin male box header with center key, 0050 pitch. AMP part # 1-04068-7. Delta Tau part # 014-00010-FPB.
