DAQmxSwitchSetTopologyAndReset

int32 DAQmxSwitchSetTopologyAndReset (const char deviceName[], const char newTopology[]);

Purpose

Resets a switch device and sets its topology to the one specified with newTopology. Use this function to initialize a switch device before scanning or making connections to ensure the initial state of that switch.

This function differs from DAQmxResetDevice because it uses the input topology name rather than the one you specify in MAX. This function does not modify the channel usage defaults you configure in MAX.

Parameters

Input
Name Type Description
deviceName const char [] The name of the device, as configured in Measurement & Automation Explorer (MAX), to which this operation applies.
newTopology const char [] The switch topology to use on the device. The following table lists examples.
