24-channel I/O module mounting racks (such as those manufactured by
Opto 22 and Gordos).
The CB-100 cable termination accessory is available from National
Instruments for use with the PC-DIO-96/PnP board. This kit includes
two 50-conductor, flat-ribbon cables and a connector block. You can
attach signal input and output wires to screw terminals on the connector
block and therefore connect signals to the PC-DIO-96/PnP I/O
connector.
The CB-100 is useful for initial prototyping of an application or in
situations where PC-DIO-96/PnP interconnections are frequently
changed. Once a final field wiring scheme has been developed,
however, you may want to develop your own cable. This section
contains information for the design of custom cables.
The PC-DIO-96/PnP I/O connector is a 100-pin, Centronics-style, male,
ribbon-cable header connector. The manufacturer and the appropriate
part number for this connector is as follows:
• Robinson Nugent (part number P50E-100P1-RR1-TG)
The mating connector for the PC-DIO-96/PnP is a 100-position,
polarized, Centronics-style, female, ribbon-socket connector with
strain relief. National Instruments uses a polarized (keyed) connector to
prevent inadvertent upside-down connection to the PC-DIO-96/PnP.
This 100-pin connector attaches to two 50-pin cables, each of which can
be connected to a 50-pin connector on the other end. The recommended
manufacturer and the appropriate part number for the 100-pin mating
connector is as follows:
• Robinson Nugent (part number P50E-100S-TG)
The recommended manufacturer part numbers for 50-pin, female,
ribbon-socket connectors suitable for use with the preceding connector
are:
• Electronic Products Division/3M (part number 3425-7650)
• T&B/Ansley Corporation (part number 609-5041CE)
