The JMACH1 connector provides the interface pins for channels 3 and 4. Usually, it is connected to a breakout
board, such as one of the Acc-8x family of boards, or an application-specific interface board.
Connector: 100-pin male box header with center key, 0050" pitch. AMP part # 1-04068-7
Delta Tau part # 014-00010-FPB.
