Analog Output Signal Connections
Pins 1 through 4 and pin 19 of the rear signal connector are analog output
signal pins. With software, you can configure pin 1, 2, 4 or 19 to connect
to the analog ground (AGND) of the module. You can use the pin that is
connected to AGND as a general analog power ground tie point to the
SCXI-1104/C module, if necessary.
Caution
The SCXI-1104/C module analog output is not overvoltage-protected. Applying
external voltages to this output can damage the SCXI-1104/C module. National
Instruments is not liable for any damage resulting from such signal connections.
Note
The SCXI-1104/C 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-1104/C 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.
