Connecting to SSR Digital Signal Conditioning
NI provides cables that allow you to connect signals from the NI 78xxR
directly to SSR backplanes for digital signal conditioning.
The NSC68-5050 cable connects the signals on the NI 78xxR RDIO
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 78xxR RDIO connectors. The other end of this cable provides
two 50-pin female headers.
