Other Connection Considerations

If you are using an MIO or MIO E Series board with 8 additional single-ended analog input
channels, remember that your DAQ board will be configured for NRSE operation and all analog
inputs are referenced to AISENSE (pin 19 on the MIO I/O connector).
Note: AISENSE is ground referenced on the SC-2043-SG. In order to avoid a ground loop,
which may affect your measurements, all analog input signals
For all other input and output signals, refer to the appropriate sections in your DAQ board user
manual for additional signal connection information.
