channel 0 and continues. You can program the SCXI-1141/1142/1143
module to start scans with any channel.
Parallel Mode
When the OUTPUT signal is configured as the rear connector output of
channel 0, the rear signal connector simultaneously carries each of the rear
connector outputs of the SCXI-1141/1142/1143 module channels on a
different pin, and the module is in parallel mode. In this mode, you can use
an SCXI-1180 feedthrough panel to make each of the outputs available at
the front of the chassis. A DAQ device cabled to an SCXI-1141/1142/1143
module in parallel mode reads a separate output signal from the module on
each of its analog inputs. You cannot multiplex the parallel outputs of a
module onto the SCXIbus. Only a DAQ device directly cabled to the
module has access to the outputs.
