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.
This manual describes how to use
LoggerNet
to connect to your datalogger
with an NL200/201. You can also use other software packages, such as
PC400
,
RTDAQ
, or
LoggerLink
Mobile App
s
for iOS and Android.
2. Cautionary Statements
x
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 .
x
Device Configuration Utility
(
DevConfig
) 2.05 or higher is required to
communicate with the NL200/201. The latest version of
DevConfig
can
be downloaded from our website at
www.campbellsci.com/downloads
.
x
The device driver for the NL200/201 must be installed on your computer
before you can connect to the NL200/201 via USB.
To install the device driver, verify you have the latest version of
DevConfig
(see previous bullet). Under Device Type, select Network
Peripheral | NL200 Series. Click the Install the device driver for the
device link and follow the prompts.
x
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
.
x
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
(p. B-1)
.
x
Ensure maximum protection against surges. Use a shielded Ethernet
cable. Keep RS-232 and CS I/O connections short. The NL200 may
require the use of external surge suppression (pn 28033). The NL201 has
integrated surge protection. The NL201 must be well grounded using the
ground lug on the case for the surge protection to work properly.
