National Instruments 653X Manuale Utente

© National Instruments Corporation

To use your 653X device with cables, signal conditioning modules, and 
other accessories that require an AT-DIO-32F pinout, use the R6850-D1, 
an optional 68-to-50-pin device adapter. Using a PSHR68-68M shielded 
cable, you can also connect the adapter to a DAQCard 6533 device.

The female side of the R6850-D1 adapter connects directly to the 
653X device or PSHR68-68M cable. The male side of the adapter provides 
the pin assignments shown in Figure C-2. The 50-pin adapter has no +5 V, 
CPULL, or DPULL pins.

National Instruments offers a variety of accessories to extend your 
653X device capabilities, including:

•

Cables and cable assemblies, shielded and ribbon

and that can isolate, amplify, excite, and multiplex signals for relays 
and analog output

accessories, including conditioning for strain gauges and RTDs,
