The NI SCXI-1200 is a 12-bit data acquisition and control module that integrates into SCXI chassis-based systems to provide analog input, analog output, digital I/O, and timing capabilities. It functions as a multifunction DAQ module in compact SCXI form factor, operating standalone or alongside other SCXI modules via the SCXI bus. The module connects to PCs and laptops through IEEE-1284 parallel ports, supporting unidirectional, PS/2 bidirectional, and Enhanced Parallel Port modes.
