Figure B-3. Connector Pinouts When Using NSC68-262650 Cable

The NSC68-5050 cable is designed to connect the signals on the
NI PXI-7831R 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 PXI-7831R DIO connectors. The other end of
this cable provides two 50-pin female headers.

Each of these 50-pin headers can be plugged directly into an 8-, 16-, 24-, or
32-channel SSR backplane for digital signal conditioning. One of the
50-pin headers contains DIO lines 0–23 from the NI PXI-7831R DIO
connector. These lines are mapped to slots 0–23 on an SSR backplane in
sequential order. The other 50-pin header contains DIO lines 24–39 from
the NI PXI-7831R DIO connector. These lines are mapped to slots 0–15 on
an SSR backplane in sequential order. You can connect to an SSR
backplane containing a number channels that does not equal the number of
