3.1CONNECTOR PIN DIAGRAM

The PCI-DAS1200 and PCI-DAS1200/JR employ a 100-pin I/O connector. Please make accurate notes and pay careful attention to wire connections. In a large system, a misplaced wire may create hours of work ‘fixing’ problems that do not exist. Note that pins 35, 36, 37, and 38 are for analog outputs and are therefore NC (no connec- tion) on the PCI-DAS1200/JR board. (Pin 77 is also NC on the /JR board).

3.2 CONNECTING SIGNALS TO THE PCI-DAS1200

The 100-pin connector provides a far greater signal density than the traditional 37-pin D type connector. In exchange for that density comes a far more complex cable and mating connector. The C100-FF-2 cable is a pair of 50-pin ribbon cables. At one end they are joined together with a 100-pin connector. From the 100-pin connector designed to mate with the PCI-DAS1200 connector, the two 50-pin ribbon cables diverge and are terminated at the other end with standard 50-pin header connectors. A CIO-MINI50 screw terminal board (or CIO-MINI50/DST with detachable screw terminals) is the ideal way to terminate real-world signals and route them into the PCI-DAS1200.
