NL240 Wireless Network Link Interface
1. Introduction
The NL240 is a WLAN (Wireless Local Area Network) interface that allows
Campbell Scientific dataloggers and peripherals to communicate with a Wi-Fi
network or wireless ad hoc network. This WLAN interface can be connected
to a datalogger’s CS I/O port or RS-232 port.
2. Cautionary Statements
•
The first time an NL240 is attached to a datalogger and Bridge Mode is
enabled, the datalogger’s 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.
•
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 Appendix E for
more information.
•
Device Configuration Utility (DevConfig) 2.03 or higher is required to
communicate with the NL240. The latest version of DevConfig can be
downloaded from our website at
•
The device driver for the NL240 must be installed on your computer
before you can connect to the NL240 via USB. To install the device
driver, verify you have the latest version of DevConfig (see previous
bullet). Under Device Type, select Network Peripheral | NL240. Click the
Install the device driver for the NL240 link and follow the prompts.
•
CR1000, CR3000, and CR800-series dataloggers require operating system
version 25 or higher in order to operate with the NL240 in bridge mode.
(OS version 25 or higher is not required to operate as a serial server or
PakBus router.) The latest operating systems can be downloaded from our
website at
•
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 NL240, do not remove
power until the red LED stops blinking.
3. Quickstart
Out of the box, the NL240 is configured for operation as a PakBus® Router.
In this mode, the NL240 can be used to communicate with Campbell Scientific
PakBus devices over a Wi-Fi network connection.
