Switch_Initiated (1)

The niSwitch Initiate Scan VI returns immediately after beginning scan list execution. It is assumed that the measurement device has already been configured and is waiting for the scanner advanced signal. The measurement should be configured to first wait for a trigger, then take a measurement. Thus, the first scanner advanced output signal of the switch module initiates handshaking.

Measurement_Device_Initiated (0)

The niSwitch Initiate Scan VI does not return until the switch hardware is waiting for a trigger input. This ensures that if you initiate the measurement device after calling the niSwitch Initiate Scan VI , the switch is sure to receive the first measurement complete (MC) signal sent by the measurement device. The measurement device should be configured to first take a measurement, send MC, then wait for scanner advanced output signal. Thus, the first MC of the measurement device initiates handshaking.
