Appendix D. Sending a New OS to the
NL241
Whenever a new operating system is released for the NL241, it will be
available from our website, www.campbellsci.com/downloads .
D.1 Sending an OS via USB
Follow these steps to send the new OS to the NL241 via USB:
1. Plug the wall charger into an AC outlet and the barrel connector into the
NL241 power jack.
2. Connect a USB cable between one of your computer USB ports and the
USB port on the NL241.
3. Open
DevConfig
.
4. Select the NL241 under Device Type .
5. Select the appropriate Communication Port .
6. Go to the Send OS tab.
7. Press the Start button.
8. In the resulting dialog box, select the file that should be sent to the device
as an operating system (this file should have an .obj extension) and press
the OK button.
9. The operating system will be sent to the NL241.
10. After the file has been sent, the LED on the NL241 will blink repeatedly
while the NL241 copies the OS into its internal flash. Depending upon the
operating system that was previously installed, it may take up to 2 minutes
for the NL241 to finish updating the operating system. While the LED is
blinking, the NL241 is in a vulnerable state where a removal of power
could leave the NL241 without a valid operating system to run. Do not
remove power until the LED stops blinking.
D.2 Sending an OS via Wi-Fi
Follow these steps to send the new OS to the NL241 via Wi-Fi:
1. Using the supplied serial cable, connect the NL241 CS I/O port to the
datalogger CS I/O port. Alternatively, power the NL241 through the
barrel-connector jack located on the edge of the device.
2. The NL241 will power up and either create or join a Wi-Fi network. After
successfully joining or creating a network, the LED will flicker green with
network activity. Note that the LED may only blink green once every few
seconds on the created network or an idle network.
