DAQCard-DIO-24 User Manual
Cabling
You can connect the DAQCard-DIO-24 to a wide range of printers,
plotters, test instruments, I/O racks and modules, screw terminal panels,
and almost any device with a parallel interface. The optional cable
available for the DAQCard-DIO-24 has a standard 50-pin header
connector. The pin assignments are compatible with standard
24-channel I/O module mounting racks (such as the SSR-24 backplane).
The CB-50 cable termination accessory is available from National
Instruments for use with the DAQCard-DIO-24. The optional
PSH27-50F-D1 cable available for your DAQCard-DIO-24 connects
directly to the CB-50 connector block. Signal input and output wires
can be attached to screw terminals on the connector block and are
thereby connected to the DAQCard-DIO-24 I/O connector.
The CB-50 or CB-50LP is useful for initial prototyping of an
application or in situations where DAQCard-DIO-24 interconnections
are frequently changed. When a final field wiring scheme has been
developed, however, you may want to develop your own cable. For
information and guidelines for the design of custom cables, see the
Custom Cables section in Chapter 1, Introduction.
If you plan to use the DAQCard-DIO-24 for a communications
application, you may need shielded cables to meet FCC requirements.
The PSH27-50F-D1 cable available for the DAQCard-DIO-24 is fully
shielded. The shield is connected only at the 25-pin end.
