The NI RC68-68 68-Pin Ribbon Cable (0.25 Meter) is an unshielded ribbon cable that connects National Instruments data acquisition and digital I/O devices to 68-pin accessories and terminal blocks. The cable features a 68-pin VHDCI connector on the device end and a 68-pin D-Type or SCSI-II female connector on the accessory end, enabling integration across NI’s X Series, M Series, and legacy E Series hardware platforms. Its flat ribbon construction simplifies cable routing and improves airflow in compact test benches.
Technical Specifications
• Connector Type: 68-pin VHDCI (device end) to 68-pin D-Type/SCSI-II female (accessory end)
• Cable Length: 0.25 meters

• Cable Type: Unshielded ribbon cable
• Form Factor: Flat ribbon, foldable
• Part Number: 187252-0R25
– Key Features
• Unshielded design delivers cost-effective connectivity for low-EMI environments
• Flat ribbon profile enables efficient cable management and storage
• Lightweight construction facilitates deployment in space-constrained systems
• Supports both multiplexed and simultaneous sampling multifunction I/O modules
– Typical Applications
• Connecting NI 63xx Series multifunction I/O modules to external accessories
• Linking E Series, S Series (except NI 6143), and B Series DAQ devices to 68-pin terminal blocks
• Integration with legacy NI DAQCard-6062E and DAQCard-6024E PCMCIA cards via 68-pin female connectors
– Compatibility & Integration
The RC68-68 operates natively with NI X Series and M Series DAQ hardware, as well as the NI 63xx Series multiplexed and simultaneous sampling multifunction I/O modules. It accommodates legacy E Series, S Series, and B Series devices through standard 68-pin accessory interfaces. For applications requiring electromagnetic shielding, NI offers alternative shielded ribbon cable solutions such as the SHC68-68-EPM.
