The National Instruments SC-2055 Cable Adapter facilitates the integration of signal conditioning accessories with National Instruments Data Acquisition (DAQ) devices. This adapter serves to convert the I/O connector signals from DAQCard-700 and PC-LPM-16/PnP devices into standard pin connections suitable for signal conditioning modules. Users can connect a DAQ device to the SC-2055 using a type NB1, 50-pin ribbon cable. It is important to power off the host computer while making this connection; one end of the ribbon cable can be connected at J1 or J2 of the SC-2055, with the other end attached to the installed DAQ device in the user’s computer. For connecting to signal conditioning accessories, the SC-2055 requires a type NB7, 26-pin ribbon cable, which links the adapter to the 5B Series backplane or any SC-206X Series boards. An 8-channel SSR Series backplane can also be interfaced using a 26-conductor ribbon cable. The SC-2055 features two 50-pin ribbon-cable connectors that are interconnected pin-by-pin, allowing for daisy chaining to additional 50-pin accessories. Moreover, the adapter includes four 26-pin ribbon-cable connectors for compatibility with the 5B Series analog signal conditioning modules and has digital ports designed for use with SC-206X Series and SSR Series modules. Although the SC-2055 has been designated as obsolete by National Instruments, it remains accessible for purchase and repair through Apex Waves. The product measures 5.2 by 4.9 by 1.9 inches and comes with a 2-3 year warranty, along with user and maintenance manuals available for download.
