98 GND Common Reference Voltage
99 +5V Output / Input +5v Power For external circuit or from external supply
100 +5V Output / Input +5v Power
The JMACH3 connector provides the interface pins for channels 5 and 6. It is usually 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.
