Custom Cabling
NI offers a variety of cables for connecting signals to the NI 7831R. If you
need to develop a custom cable, a nonterminated shielded cable is available
from NI. The SHC68-NT-S connects to the NI 7831R VHDCI connectors
on one end of the cable. The other end of the cable is not terminated. This
cable ships with a wire list identifying the wires that correspond to each
NI 7831R pin. Using this cable, you can quickly connect the NI 7831R
signals that you need to the connector of your choice. Refer to Appendix B,
Connecting I/O Signals, for the NI 7831R connector pinouts.
NSC68-262650 Non-shielded cable connects
from 68-pin VHDCI male
connector to two 26-pin
female headers plus one
50-pin female header. The
pinout of these headers
allows for direct connection
to 5B backplanes for analog
signal conditioning and SSR
backplanes for digital signal
conditioning.
MIO only 26-pin headers can connect
to the following 5B
backplanes for analog signal
conditioning:
• 5B08 (8-channel)
• 5B01 (16-channel)
50-pin header can connect to
the following SSR
backplanes for digital signal
conditioning:
• 8-channel backplane
• 16-channel backplane
• 32-channel backplane
NSC68-5050 Non-shielded cable connects
from 68-pin VHDCI male
connector to two 50-pin
female headers. The pinout
of these headers allows for
direct connection to SSR
backplanes for digital signal
conditioning.
DIO only 50-pin headers can connect
to the following SSR
backplanes for digital signal
conditioning:
• 8-channel backplane
• 16-channel backplane
• 32-channel backplane
