2.6 Connector Pin Assignments

2.6.1 PCI-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 2.2 PCI-7200's layout.
CN2 is used for digital inputs (DI 0 ~ DI 15) and digital outputs (DO 0 ~ DO 15),
and the reminder digital I/O channels DI 16 ~ DI 31 and DO 16 ~ DO 31 are
presented on the CN1. The pin assignment of CN1 and CN2 is illustrated in the
figure 2.2 and 2.3.
Legend:
DO n : Digital Output CH n
DI n : Digital Input CH n
GND : Ground
ACK : ACK Signal of handshaking communication
REQ : REQ Signal of handshaking communication
I_TRG: Input signal to start the DI data sampling
O_TRG: Output signal can be controlled by software
