Connector Pinouts
NI myRIO-1950 Expansion Port (MXP) connectors A and B carry identical sets of signals. The
signals are distinguished in software by the connector name, as in
ConnectorA/DIO1 and
ConnectorB/DIO1. Refer to the software documentation for information about configuring
and using signals. The following figure and table show the signals on MXP connectors A and B.
Note that some pins carry secondary functions as well as primary functions.
