Chapter 2 Configuration and Installation
© National Instruments Corporation 2-3 SC-2040 User Manual
The SC-2040 has one switch that controls whether the board is powered from an external supply
or from the MIO-16E board. Furthermore, two jumpers control how the board is shielded and
grounded. Additionally, there are eight sets of switches and jumpers that configure the gain
settings and input modes of the eight SC-2040 channels.
