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.

3.2 Configuring the NL200/201
INSTALL THE DEVICE DRIVER BEFORE plugging the
NL200/201 into your PC for the first time. You will need the
device driver properly installed 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.
NOTE

Ensure the NL200/201 is powered.
Connect the supplied USB cable between a USB port on your computer and
the USB port on the NL200/201.
Open Device Configuration Utility (DevConfig).
Under Device Type, select “NL200”.
Click the Browse button next to “Communication Port”.
Select the port labelled “NL200”.
Click OK.
Click Connect.
To enter a static IP address, select “disable”in the Use DHCP field. Then
input the IP Address, Network Mask, and Default Gateway. These values can
be provided by your network administrator.
If a dynamic address is to be used, the network information acquired via
DHCP can be seen on the NL200 tab.
Click Apply to save your changes.
It is recommended that a static IP address be given to the
NL200/201 for most applications so that the path to the device is
always known. If using a dynamic IP address acquired via DHCP
you may wish to configure the NL200/201 as a PakBus/TCP client.
3.3 LoggerNet Setup
The next step is to run LoggerNet and configure it to connect to the datalogger via
the NL200/201.
In LoggerNet’s Setup Screen, press Add Root and choose “IPPort”. Input the
NL200/201’s IP address and port number. The IP address and port numbers
are input on the same line separated by a colon. IPv6 addresses will need to
be enclosed in square brackets when specifying a port number. An IPv4
address may look like 192.168.1.100:6785. An IPv6 address may look like
[2001:db8::1234:5678]:6785. A fully qualified host name entry may look
like yourlogger.com:6785.
Add a PakBus Port (PakBusPort).
Add a PakBus Router (pbRouter). Input the PakBus address of the
NL200/201. The NL200/201’s default PakBus address is 678.
Add the datalogger and input the PakBus address of the datalogger.
Press Apply to save the changes.
You can verify that your settings are correct by selecting the datalogger in the
Network Map, selecting the Clock tab, and pressing Check Clocks. If your
settings are correct, you should see the current clock of your server and
datalogger.

4. Overview
The NL200/201 Network Link Interface is a device used to communicate with
Campbell Scientific dataloggers and peripherals using an Ethernet 10/100 Mbps
communications link. The NL200/201 includes a CS I/O port and an RS-232 port
for communication. A USB device port is used for configuring the NL200/201
device.

Figure 4-1. NL201
Bridge Mode Enabled
The NL200/201 can be configured to bridge Ethernet and CS I/O communications
(Bridge Mode enabled). This mode is used for providing access to the internal IP
functionality of the CR800/850, CR1000, and CR3000 (e.g., web page access,
email, FTP, etc.). Bridge mode does not utilize PPP. Instead, raw IP packets are
transferred between the Ethernet and CS I/O connections.
Figure 4-2. Bridge Mode enabled
Bridge Mode Disabled
With Bridge Mode disabled, the NL200/201 can be configured to act as a serial
server and/or a PakBus router. The NL200/201 can act as a serial server and
PakBus router simultaneously. However, each physical port (RS-232 and CS I/O)
is only associated with one service (Pakbus router, serial server, Modbus/TCP
Gateway, etc.) at a time. Therefore, you can have an RS-232 serial server and a
CS I/O serial server, an RS-232 serial server and a CS I/O PakBus router, an RS-
232 PakBus router and a CS I/O serial server, or an RS-232 PakBus router and a
CS I/O PakBus router. In addition, the NL200/201 can act as TLS proxy server.
The TLS proxy server is independent of other modes.

Figure 4-3. Bridge Mode disabled
Some reasons you might want to use each of these modes are described below.
Refer to Section 6, Configuring the NL200/201, and Section 7, Operation, for
information on setting up your NL200/201 for each mode.
Campbell Scientific’s LoggerNet software is used to communicate with the
dataloggers once the NL200/201 is configured properly and connected to a
network.
Bridge Mode
Allows access to datalogger’s internal IP functionality when a peripheral port
is not accessible. For example accessing the HTTP/webpage, email, and FTP
capabilities of a CR800/850, ET107, RAWS, or CS110.

User Manual

Serial Server
Allows access to a CR10X over Ethernet (RS-232 serial server) when used in
conjunction with an RS-232 to CS I/O (ME) adapter like the SC32B or
SC105.
Allows access to a serial sensor over Ethernet (RS-232 serial server).
Provides an Ethernet to RF500M Base. (RS-232 serial server).
PakBus Router
Allows access to a CR10X-PB over Ethernet.
Allows access to a CR200X over Ethernet.
Allows you to connect to a PakBus Device on the RS-232 port and a PakBus
Device on the CS I/O port using only one TCP port.
Allows a PakBus device on the RS-232 port and a PakBus device on the CS
I/O port to communicate with each other without routing through the
Ethernet.
Allows multiple computers to concurrently talk to PakBus devices connected
to the RS-232 and CS I/O ports.
TLS Proxy Server
Adds an encrypted Ethernet network interface to a datalogger that supports
CS I/O IP (bridge mode) communications.

Launch DevConfig.
Under Device Type, select “NL200”.
Check the box labelled “Use IP Connection”.
Click the Browse button next to “Communication Port”.
Select the NL200/NL201 to be configured from the resulting pop-up window.
Enter “nl200” in the TCP Password box. (“nl200” is the default
administrative password. It can be changed via the DevConfig
Deployment/NL200 tab.)
Click OK.
Click Connect.
Configure the NL200/201 as needed for your application.
Click Apply to save your changes.
6.3 Configuring the NL200/201 via Telnet
The NL200/201 must have an IP address before connecting via
Telnet. Configuration via Telnet is not available in bridge mode.
Ensure the NL200/201 is powered and connected to your network.
Create a Telnet session with the device over port 23.
Input the NL200/201 Admin Password (default password is nl200).
