Connecting to 5B and SSR Signal Conditioning
NI provides cables that allow you to connect signals from the NI 783xR
directly to 5B backplanes for analog signal conditioning and SSR
backplanes for digital signal conditioning.
directly to 5B backplanes for analog signal conditioning and SSR
backplanes for digital signal conditioning.
The NSC68-262650 cable connects the signals on the NI 783xR MIO
connector directly to 5B and SSR backplanes. This cable has a 68-pin male
VHDCI connector on one end that plugs into the NI 783xR MIO connector.
The other end of this cable provides two 26-pin female headers plus one
50-pin female header.

The other end of this cable provides two 26-pin female headers plus one

One of the 26-pin headers contains all the NI 783xR analog input signals.
You can plug this connector directly into a 5B backplane for analog
input signal conditioning. The NI 783xR AI<0..n> correspond to the
5B backplane channels <0..n> in sequential order. Configure the AI
channels to use the NRSE input mode when using 5B signal conditioning.

The other 26-pin header contains all the NI 783xR analog output signals.
You can plug this connector directly into a 5B backplane for AO signal
conditioning. The NI 783xR AO<0..n> correspond to the 5B backplane

The 50-pin header contains the 16 DIO lines available on the NI 783xR
MIO connector. You can plug this header directly into an SSR backplane
for digital signal conditioning. DIO lines <0..15> correspond to the
5B backplane Slots <0..15> in sequential order.

The 5B connector pinouts are compatible with eight-channel 5B08
backplanes and 16-channel 5B01 backplanes. The NI 7830R can accept
analog input from the first four channels of a 16-channel backplane. The
NI 7831R/7833R can accept analog input from the first eight channels of a
16-channel backplane. The SSR connector pinout is compatible with
eight-, 16-, 24-, and 32-channel SSR backplanes. You can connect to an
SSR backplane containing a number of channels unequal to the 16 DIO
lines available on the 50-pin header. In this case, you have access to only
the channels that exist on both the SSR backplane and the NSC68-262650
cable 50-pin header.
