Scanning Other SCXI Modules Through the SCXI-1581
When connected as the cabled module in an SCXI chassis, the SCXI-1581
can route the multiplexed signals from other SCXI modules to the E Series
DAQ device. The SCXI-1581 routes multiplexed signals from other SCXI
modules to the E Series DAQ device even though the SCXI-1581 does not
have any analog-input channels.
