The JMACH2 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, 0.050" pitch. AMP part # 1-04068-7
Delta Tau part # 014-00100-FPB.
TB1 (2/4-Pin Terminal Block)
This terminal block can be used to provide the input for the power supply for the circuits on the PMAC2
board when it is not in a bus configuration. When the PMAC2 is in a bus configuration, these supplies
come through the bus connector from the bus power supply automatically; in this case, this terminal block
should not be used.
