MIO-type board. When you use the SCXI-1161 with an SCXI-1341,
SCXI-1342, or SCXI-1344 cable assembly, the SCXI-1161 signals
match the digital lines of the Lab-NB/Lab-PC/Lab-PC+ boards, the
PC-LPM-16/PnP board, and the Lab-LC board, respectively. When you
configure the SCXI-1161 for a DIO-type board, the digital I/O signals
of the SCXI-1161 match the digital I/O lines of the DIO-24 and DIO-96
boards. When you use the SCXI-1161 with an SCXI-1348 cable
assembly, the SCXI-1161 signals match the digital lines of the DIO-32F
