3.2.2
Connection cable ST075 (APCIe-7500)
This cable converts the 37-pin D-Sub male connector of the
APCIe-7500
board to four 9-pin D-Sub
female connectors. The pin assignment is to be found in Chapter 3.2.1.
3.2.3
Connection cables ST074 (APCIe-7500) and ST7825 (APCIe-7800)
The
ST074
cable converts the 37-pin D-Sub male connector of the
APCIe-7500
board to four 25-pin
D-Sub female connectors.
The
ST7825
cable converts the 78-pin D-Sub male connector of the
APCIe-7800
board to eight 25-pin
D-Sub female connectors.
