Can I use the unused analog input channels of the E/M Series DAQ
device if I am directly cabled to the SCXI-1102/B/C, for example with
the SCXI-1180 feedthrough?
Yes. E/M Series DAQ device channels 1 through 7 are available when
directly connected to the SCXI-1102/B/C.
Which digital lines are unavailable on the E/M Series DAQ device if I
am cabled to an SCXI-1102/B/C module?
Table D-1 shows the digital lines that are used by the SCXI-1102/B/C for
communication and scanning. These lines are unavailable for
general-purpose digital I/O if the SCXI-1102/B/C is connected to the
E/M Series DAQ device.
