The National Instruments part number 776515-00 is a cable adapter identified as the SC-2054, specifically designed for signal conditioning applications. This adapter facilitates the connection between the I/O connector of various data acquisition devices and a range of signal conditioning accessories, including compatibility with the SC-204x, SC-206x, 5B, SSR, and ER-8/16 Series. By minimizing measurement errors, the NI 776515-00 ensures accurate data acquisition results. It effectively converts half of the 96 digital connector signals to standard pin connections and is particularly suitable for use with 6508, DIO-96, and DIO-24 devices, though the SC-2051 model is advised for DIO-24 usage.

The adapter features four 50-pin ribbon connectors and six 26-pin ribbon connectors, complemented by metal standoffs for stable placement on a workbench or near a host device. An optional rack mount is available separately for enhanced installation flexibility. It operates without requiring additional software beyond that used for the associated DAQ device. The 776515-00 routes I/O signals efficiently and is widely utilized in applications such as aviation, laboratory testing, industrial control, and robotics. It is essential that users only connect the adapter with compatible devices and avoid linking two accessories that share common I/O signals. The dimensions of the adapter are 7.9 x 4.9 x 1.9 inches, with an operational temperature range of 0° C to 70° C and a storage temperature range of -55° C to 150° C. While National Instruments has designated this part as obsolete, it remains available for purchase and repair through the Apex Waves website.
