Appendix C Connecting Signals with Accessories
© National Instruments Corporation C-7 653X User Manual
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.
