Ensure maximum protection against surges. Use coaxial surge protection. Keep RS-232 and
CS I/O connections short.

When downloading a new operating system to the NL241, do not remove power until the
LED stops rapidly flashing red and green.
3. QuickStart
Out of the box, the NL241 is configured for operation as a PakBus router and to create an open
Wi-Fi network called “NL241_
SerialNumber
”. In this mode, the NL241 can be used to
communicate with Campbell Scientific PakBus devices using a Wi-Fi-enabled device such as a
smart phone. The following instructions indicate how to use an NL241 to connect to a data
logger using a smart phone with the Campbell Scientific
LoggerLink
Mobile App.
3.1 Physical setup
As shown in
(p. 3), attach an antenna to the NL241 Antenna connector. Using the
supplied serial cable, connect the NL241 CS I/O port to the data logger CS I/O port. This cable
supplies communications and power from the data logger to the NL241. Ensure that the device is
powered by inspecting the LED. The LED will be solid red when the device is connecting to or
creating a Wi-Fi network. When the LED starts flashing green, it is ready for Wi-Fi
communications. For more information see
