2.6.1PCI-7200 Pin Assignments

The PCI-7200 comes equipped with one 37-pin D-Sub connector (CN2) located on the rear mounting plate and one 40-pin female flat cable header connector (CN1). The CN2 is located on the rear mounting plate; the CN1 is on front of the board. Refer section 2.4 PCI-7200‘s layout.

CN2 is used for digital inputs (DI 0 to DI 15) and digital outputs (DO 0 to DO 15) The reminding digital I/O channels DI 16 to DI 31 and DO 16 to DO 31 are on CN1. The pin assignment of CN1 and CN2 is illustrated in the Figures 2.2 and 2.3.
