	(on the PC).
	• The NI-series of Integrated Controllers comes factory defaulted to a

	Port DIP switch is set to the user selected communication speed.
	Refer to the Setting the Configuration DIP Switch (for the Program
	Port) section on page 17 for more information.
	• If a higher Communication speed is being used (115200), try going to
	the lower Baud Rate of 38400. Refer to the Configuration and

	the NI-4000 until the cards connectors "snap" into the rear connector.
	Without this proper connection of the cards to the rear of the slot, the
	NI Controller might not detect them properly.
	• From the Main NetLinx Studio menu, go to Tools > Reboot the

	and makes it re-detect the inserted cards.
	• If NetLinx Studio still does not detect the cards, cycle power to the
	Controller and repeat the above steps.
