Custom Cables

National Instruments currently offers a cable termination accessory, the

CB-50, for use with the PC-LPM-16/PnP. This kit includes a

terminated, 50-conductor, flat ribbon cable and a connector block.

Signal input and output wires can be attached to screw terminals on the

connector block and connected to the PC-LPM-16/PnP I/O connector.

The CB-50 is useful for the initial prototyping of an application or in

situations where PC-LPM-16/PnP interconnections are frequently

changed. Once you develop a final field wiring scheme, however, you

may want to develop your own cable. This section contains information

and guidelines for the design of custom cables.

The PC-LPM-16/PnP I/O connector is a 50-pin, male, ribbon cable

header connector. The following list gives recommended part numbers

for use with your PC-LPM-16/PnP board:

• Electronic Products Division/3M (part number 3596-5002)

• T&B/Ansley Corporation (part number 609-5007)

The mating connector for the PC-LPM-16/PnP is a 50-position,

polarized, ribbon socket connector with strain relief. National

Instruments uses a polarized (keyed) connector to prevent inadvertent

upside-down connection to the PC-LPM-16/PnP. Recommended

manufacturer part numbers for this mating connector are as follows:

• Electronic Products Division/3M (part number 3425-7650)

• T&B/Ansley Corporation (part number 609-5041CE)

The following are the standard ribbon cables (50-conductor, 28 AWG,

stranded) that can be used with these connectors:

• Electronic Products Division/3M (part number 3365/50)

• T&B/Ansley Corporation (part number 171-50)
