Caution
The SCXI-1112 module analog outputs are not overvoltage protected. Applying
external voltages to these outputs can damage the SCXI-1112 module. National
Instruments is not liable for any damages resulting from such signal connections.
Note
The SCXI-1112 module analog outputs are short-circuit protected.
Digital I/O Signal Connections
Pins 24 through 27, 29, 33, 36, 37, 43, and 46 constitute the digital I/O lines
of the rear signal connector.
The SCXI-1112 module digital input and output signals correspond to the
digital I/O lines of E Series MIO DAQ devices. Table 3-1 lists the
equivalencies.
