Pin 3 is the main output, and pin 4 is its reference signal. All eight channels are multiplexed onto this output when the module is software-configured for multiplexed scanning mode. In parallel scanning mode, the output of pin 3 is the output of one selected channel. Channel 0 is the power-up and reset default. When scanning multiple modules, you can also connect this output to the SCXIbus analog bus and the analog bus will drive this output. Pins 5, 7, 9, 11, 13, 15, and 17 are direct outputs from channels 1 through 7, respectively. In parallel mode, all eight channels are available simultaneously at the rear connector. Pins 6, 8, 10, 12, 14, 16, and 18 are the reference signals for outputs 1 through 7. Caution The SCXI-1141/1142/1143 module analog outputs are not overvoltage protected, although they are short-circuit protected. Applying external voltage to these outputs can result in damage to the SCXI-1141/1142/1143 module. NI is not liable for any damage resulting from such signal connections. Digital I/O Signal Connections Pins 24 through 27, 29, 33, 36, 37, and 43 constitute the digital I/O lines of the rear signal connector. Each of these pins is in one of three categories—digital input signals, digital output signals, and timing signals. Pins 24 and 33 are the digital ground reference for all of the DAQ device digital signals and are tied to the module digital ground. The digital input signals are pins 25, 27, 29, and 37. Each digital line emulates an SCXIbus communication signal as follows: • Pin 25 is SER DAT IN and is equivalent to the SCXIbus MOSI serial data input line. • Pin 27 is DAQ D*/A and is equivalent to the SCXIbus D*/A line. Pin 27 indicates to the module whether the incoming serial stream on SER DAT IN is data (DAQ D*/A = 0) or address (DAQ D*/A = 1) information. • Pin 29 is SLOT 0 SEL* and is equivalent to the SCXIbus INTR* line. Pin 29 indicates whether the data on the SER DAT IN line is being sent to Slot 0 (SLOT 0 SEL* = 0) or to a module (SLOT 0 SEL* = 1). • Pin 37 is SER CLK and is equivalent to the SCXIbus SPI CLK line. Pin 37 is used to clock the serial data on the SER DAT IN line into the module registers
