Appendix D. Sending a New OS to the
NL200/201
Whenever a new operating system is released for the NL200/201, 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 NL200/201 via USB:
1. Using the supplied serial cable, connect the NL201’s CS I/O port to the
datalogger’s CS I/O port. Alternatively, power the NL200 or NL201
through the barrel-connector jack located on the edge of the device.
2. Connect a USB cable between one of your computer’s USB ports and the
USB port on the NL200.
3. Open
DevConfig
.
4. Select the NL200 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 NL200/NL201.
10. After the file has been sent, the power LED on the NL200/NL201 will
blink repeatedly while the NL200/NL201 copies the OS into its internal
flash. This process takes about 10 seconds. While the LED is blinking,
the NL200/NL201 is in a vulnerable state where removal of power will
leave the NL200/NL201 without a valid operating system to run. DO
NOT remove power until the LED stops blinking.
D.2 Sending an OS via IP
Follow these steps to send the new OS to the NL200/201 via IP:
1. Using the supplied serial cable, connect the NL201’s CS I/O port to the
datalogger’s CS I/O port. Alternatively, power the NL200 or NL201
through the barrel-connector jack located on the edge of the device.
2. Using an Ethernet cable, connect the device to your network or directly to
your computer Ethernet port. A crossover cable is not required if
connecting directly to the computer.
