Figure B-3. Connector Pinouts when Using NSC68-262650 Cable
The NSC68-5050 cable connects the signals on the NI 783xR DIO
connectors directly to SSR backplanes for digital signal conditioning. This
cable has a 68-pin male VHDCI connector on one end that plugs into the
NI 783xR DIO connectors. The other end of this cable provides two 50-pin
female headers.
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 783xR DIO 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 783xR
