NL200/201 Network Link Interface
1. Introduction
The NL200/201 Network Link Interface allows Campbell Scientific dataloggers
and peripherals to communicate over a local area network or a dedicated Internet
connection. This serial to Ethernet interface can be connected to a datalogger’s
CS I/O port or other devices via RS-232.
2. Cautionary Statements

The first time an NL200/201 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 .

The device driver for the NL200/201 must be installed on your computer
before you can connect to the NL200/201 via USB. See Appendix D,
NL200/201 Driver Installation Instructions , for instructions on installing the
device driver.

Device Configuration Utility 2.05 or higher is required to communicate with
the NL200/201. The latest Device Configuration Utility can be downloaded
from our website at
www.campbellsci.com/downloads .

CR1000, CR3000, and CR800-series dataloggers require operating system
version 23 or higher in order to operate with the NL200/201 in bridge mode.
The latest operating systems can be downloaded from our website at
www.campbellsci.com/downloads .

The NL200 is not powered over CS I/O or USB. An external power adapter
or power cable is required. The NL201 can be powered by the CS I/O port or
an external power adapter or power cable. If you wish to prevent the NL201
from being powered by the CS I/O port, see Appendix B,
Cables, Pinouts,
LED Function, and Jumper .

Ensure maximum protection against surges. Use a shielded Ethernet cable
and external surge protection. Keep RS-232 and CS I/O connections short.
3. Quickstart
Out of the box, the NL200/201 is configured for operation as a PakBus Router. In
this mode, the NL200/201 can be used to communicate with Campbell Scientific
PakBus devices over an Ethernet / Internet network connection.
3.1 Physical Setup
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. Connect the NL200/201
to your network using an Ethernet cable, attaching one end of the cable to the
NL200/201’s Ethernet port and the other end to your network. Ensure that the
device is powered up by inspecting the Power LED.
