1. Introduction
The NL241 is a WLAN (wireless local area network) interface that allows Campbell Scientific data
loggers and peripherals to communicate with a Wi-Fi network. The NL241 can either join an
existing network or create a network. This WLAN interface can be connected to a data logger
CS I/O port or RS-232 port.
2. Precautions
l
READ AND UNDERSTAND the
section at the back of this manual.

The first time an NL241 is attached to a data logger and bridge mode is enabled, the data
logger memory has to be reorganized to allow room in memory for the IP stack. To avoid
the loss of data, collect your data before enabling bridge mode. Note that once the NL241
is attached, it can take up to 10 seconds for the data logger to recognize it.
l
This equipment generates, uses, and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions, may cause harmful interference to
radio communications. See
(p. 66) for more information. Radio
installations should be performed by a professional. It is very important that the transmit
power level selected and the gain of the attached antenna do not exceed the maximum
allowed ERP permitted by local regulations. Regulations vary by country and region. As the
equipment owner, you are responsible for making sure that your installation and
maintenance of the radio equipment ensure local regulations are met.
