C.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 data logger 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 flash with network activity. Note that the LED
may only flash once every few seconds on the created network or an idle
network.
3. If the device is configured to create a network, the computer must join the NL241 created
network. If the NL241 has been previously configured to join a network, join the same
network with your computer.
4. Open
Device Configuration Utility
.
5. Select the NL241 under Device Type.
6. Ensure that the Use IP Connection box is checked on the left-hand panel.
7. If the Admin Password of the device has been set, enter that password in the Administrative
Password control on the left panel in order for the connection to succeed.
8. Enter the IP address or domain name address of the device in the Communications Port
control on the left panel. If you do not know the address of the device and the device is
connected to your local area network, you may be able to Browse
to the right of
Communications Port to discover the list of devices on the network. Whatever address is
entered, it must end with :6786 in order to connect the device configuration service.
9. Go to the Send OS tab.
10. Click Start.
11. 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 click OK.
12. The operating system will be sent to the NL241.
13. After the file has been sent, the LED on the NL241 will flash 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 flashing, 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 flashing.
