2.6.3 cPCI-7249R Pin Assignment
The I/O ports of cPCI-7249R emulate the mode 0 configuration of
the 8255 general purpose programmable peripheral interface. This
card comes equipped with a SCSI-100 Pin connector. The cPCI-
7249R supports a R7249 daughter board for rear I/O and includes
two OPTO-22 connectors as well as a SCSI -100 connector.
The DIO pin names are specified as PnXb, where
n: means the connector reference number n=1-2
X: means the port name, X= A, B or C
b: means the bit number of a port, b=0-7
For example, P1C4 means bit 4 of port C on connector CN1
EXTCLK:
External edge trigger signal for latch digital input data
EVENT:
External clock source for counter 0
V5V :Onboard un-regulated 5V power supply output
+12V : Onboard un-regulated +12V power supply output
