DIO 0–23 Connector
R Series Multifunction RIO User Manual
You can plug each of these 50-pin headers directly into an 8-, 16-, 24-,
or 32-channel SSR backplane for digital signal conditioning. One of the
50-pin headers contains DIO<0..23> from the NI 78xxR RDIO connector.
These lines correspond to Slots <0..23> on an SSR backplane in sequential
order. The other 50-pin header contains DIO<24..39> from the NI 78xxR
RDIO connector. These lines correspond to Slots <0..15> on an SSR
backplane in sequential order. You can connect to an SSR backplane
containing a number of channels unequal to the number of lines on the
NSC68-5050 cable header. In this case, you have access only to the
channels that exist on both the SSR backplane and the NSC68-5050 cable
header you are using.
Figure A-4 shows the connector pinouts when using the NSC68-5050
cable.
