Appendix C
Custom Cable Design
This appendix describes the pin connections on the DAQCard-500, which you will need to use
only if you are designing your own cable.
The recommended cable for the DAQCard-500 is the National Instruments PR27-30F. This
cable has a 27-pin male connector that mates with the 27-pin female connector on the
DAQCard-500. Figure C-1 shows the pin assignment for the 27-pin female connector on the
DAQCard-500. You should use the pin assignment in Figure C-1 only for custom cable design.
If you are using the National Instruments 27-30F cable, you should use the pin assignment
shown in Figure 3-1.
The other end of the cable uses a 30-pin, insulation displacement, male ribbon-cable header
connector. National Instruments uses a polarized (keyed) connector to prevent inadvertent
upside-down connection to the CB-27. Recommended manufacturer part number for this mating
connector is as follows:
• AMP Manufacturing (part number 746288-7)
The following are the standard ribbon cables (30-conductor, 28 AWG, stranded) that work with
the 30-pin connectors:
• Electronic Products Division/3M (part number 3365-30)
• T&B/Ansley Corporation (part number 171-30)
