Custom Cabling

NI offers a variety of cables for connecting signals to the NI783xR. If yo u

need to develop a custom cable, a nonterminated shielded cable is available

from NI. The SHC68-NT-S connects to the NI783xR 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

NI7 83xR pin. Using this cable, you can quickly connect the NI 783xR

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
