The DriverSetup keyword is set using the driver setup string, and comprises the resource name (multi-instrument sessions only), instrument model number, and bus connector.

When you specify the driver setup string, NI-DCPower uses the option string parameter of niDCPower Initialize With Independent Channels to determine the following:

  • How many instruments to simulate;
  • Which channel numbers to use; and
  • Which channels belong on which simulated instrument.

If you do not specify the driver setup string, NI-DCPower simulates the device specified in the resource name parameter.

You do not have to specify a value for all the option string properties. If you do not specify a value for a property, NI-DCPower uses the default value. If you specify a Model but not a BoardType, the driver infers the board type. If you specify neither the driver setup string nor the resource name parameter, or if you do include a driver setup string that excludes a Model, NI-DCPower simulates the device by default.
