NI SHC68-68-RDIO High-performance shielded cables designed specifically for R Series Connectivity to 68-pin terminal blocks Use with NI cRIO-9151 chassis for analog and digital I/O expansion/signal conditioning Increased signal integrity and noise immunity Use with DIO connectors on R Series intelligent devices Each digital I/O line internally twisted with digital ground Overview The National Instruments SHC68-68-RDIO cable is a high-performance shielded 68-conductor cable terminated with a VHDCI 68-pin male connector at one end, and a 68-pin female 0.050 D-type connector at the other. This cable has been designed and shielded specifically for the DIO connector on R Series intelligent DAQ devices. Beyond the basic external shielding, each of the digital input/output lines is individually twisted with digital ground for high signal integrity and noise immunity. This cable is also the recommended for use with the cRIO-9151 R Series expansion chassis. For the multifunction I/O (MIO) connector on R Series devices, use the SHC68-68-RMIO cable. Data Sheet
