NL200 Network Link Interface
1. Introduction
The NL200 Network Link Interface allows Campbell Scientific dataloggers to
communicate over a local area network or a dedicated Internet connection.
This Ethernet interface can be connected to either the datalogger’s CS I/O port
or RS-232 port.
2. Cautionary Statements
• The device driver for the NL200 must be installed on your computer
before you can connect to the NL200 via USB. See Appendix D for
instructions on installing the device driver.
• Device Configuration Utility 2.01 or higher is required to communicate
with the NL200. The latest Device Configuration Utility can be
downloaded from our website, www.campbellsci.com/downloads
.
• CR1000, CR3000, and CR800-series dataloggers require operating system
version 23 or higher in order to operate with the NL200 in bridge mode.
The latest operating systems can be downloaded from our website,
www.campbellsci.com/downloads
.
• Ensure maximum protection against surges. Use a shielded Ethernet cable
or external surge protection. Keep RS-232 and CS I/O connections short.
3. Quickstart
Out of the box, the NL200 is configured for operation as a CS I/O and RS-232
serial server. In this mode, the NL200 can be used to communicate with nearly
all current Campbell Scientific devices over an Ethernet / Internet network
connection.
3.1 Physical Set-up
Power the NL200 through the barrel connector jack located on the edge of the
device. Connect the NL200 to your local network using an Ethernet cable,
attaching one end to the NL200's Ethernet port and the other end to your
network. Connect the supplied SC12 serial cable from the NL200’s CS I/O
port to the datalogger’s CS I/O port or from the NL200’s RS-232 port to the
datalogger’s RS-232 port.
