R Only)
NI provides cables that allow yo
u
to connect signals from the
NI 783 x R/784 x R/785 x R 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 783
x R/784 x R/785 x R RMIO connector directly to 5B and SSR
backplanes. This cable has a 68-pin male VHDCI connector on one end that
pl
u
gs into the NI 783 x R/784 x R/785 x R RMIO connector. The other end of
this cable provides two 26-pin female headers pl
u
s one 50-pin female
header.
One of the 26-pin headers contains all the NI 783 x R/784 x R/785 x R analog
inp
u
t signals. Yo
u
can pl
u
g this connector directly into a 5B backplane for
analog inp
u
t signal conditioning. The NI 783 x R/784 x R/785 x R AI<0.. n >
correspond to the 5B backplane channels <0.. n > in seq
u
ential order.
Config
u
re the AI channels to
u
se the NRSE inp
u
t mode when
u
sing
5B signal conditioning.
The other 26-pin header contains all the NI 783 x R/784 x R/785 x R analog
o
u
tp
u
t signals. Yo
u
can pl
u
g this connector directly into a 5B backplane
for AO signal conditioning. The NI 783 x R/784 x R/785 x R AO<0.. n >
correspond to the 5B backplane channels <0.. n > in seq
u
ential order.
The 50-pin header contains the 16 DIO lines available on the
NI 783
x R/784 x R/785 x R RMIO connector. Yo
u
can pl
u
g this header
directly into an SSR backplane for digital signal conditioning. DIO lines
<0..15> correspond to the 5B backplane Slots <0..15> in seq
u
ential order.
The 5B connector pino
u
ts are compatible with 8-channel 5B08 backplanes
and 16-channel 5B01 backplanes. The NI 7830R can accept analog
inp
u
t from the first fo
u
r channels of a 16-channel backplane.
The NI 7831R/7833R/784 x R/785 x R can accept analog inp
u
t from the
first eight channels of a 16-channel backplane. The SSR connector pino
u
t
is compatible with 8-, 16-, 24-, and 32-channel SSR backplanes. Yo
u
can
connect to an SSR backplane containing a n
u
mber of channels
u
neq
u
al to
the 16 DIO lines available on the 50-pin header. In this case, yo
u
have
access to only the channels that exist on both the SSR backplane and the
NSC68-262650 cable 50-pin header.
