NL100/105 Network Link Interface
1. Introduction
The NL100 and NL105 Network Link Interfaces are devices used to
communicate with Campbell Scientific dataloggers using an Ethernet 10 BaseT communications link. The NL100 includes a CS I/O port (see Appendix A)
an RS-232 port, and an RS-485 port for communication; the NL105 adds a
TLink interface for communication with a CR9000(C) system.
The NL100/105 can be configured to act as a Serial Server in a standard
TCP/IP network, to act as a PakBus node in a PakBus network, or to transfer
MODBUS/TCP packets. All of the available settings are described in Section
2.4. However, not all settings are required for all configurations. This manual
will focus mainly on setting up the NL100/105 for a standard TCP/IP network.
For PakBus and MODBUS configurations, please contact Campbell Scientific
for applications notes or other information that may be available.
Campbell Scientific's LoggerNet software is used to communicate with the
dataloggers once the NL100/105 is configured properly and connected to a
network (refer to Section 2.). Communication with CSI’s mixed-array
dataloggers (CR10X, CR510, CR23X, CR7, and 21X) and table-data
dataloggers (CR10X-TD, CR510-TD, CR23X-TD, CR5000, and CR9000)
requires LoggerNet version 2.0 or greater. Communication with CR10XTDPB, CR510TD-PB, CR23XTD-PB, and CR200 dataloggers requires
LoggerNet 2.1 or greater. Communication with the CR1000 requires
LoggerNet 3.0 or greater. Communications with the CR3000 require
LoggerNet 3.2 or greater and with the CR800 and CR850 require LoggerNet
3.3 or greater. PC208W version 3.2 or higher may also be used with mixed
array dataloggers (CR10X, CR510, CR23X, CR7, 21X). PC9000 may also be
used for CR9000 and CR5000 dataloggers.
1.1 Physical Description of the NL100/105
The NL100/105 is housed in a rectangular case with all power and
communication connections on one edge. On the opposite outside edge are tabs
for mounting the NL100/105 in an enclosure. Figure 1 below shows the
position of these connections and the mounting tabs.

Power Supply Requirements
The NL100/105 is powered via the green G 12V connector (11 to 16
VDC at 140 mA average current) on the front panel of the unit.
Cable Specifications
The Ethernet 10 Base-T cable should be a Category 5 twisted pair cable.
Campbell Scientific recommends the 13658. The two active pairs in an
Ethernet 10 Base-T network are pins 1 & 2 and pins 3 & 6. Use only
dedicated wire pairs (such as blue/white & white/blue, orange/white &
white/orange) for the active pairs.
RJ-45 Pin-Outs: Pin 1 = TD+, Pin 2 = TD-, Pin 3 = RD+, Pin 6 = RD-
A DB9 female to DB9 male cable such as the 10873 is used to connect
the NL100’s RS-232 port to the datalogger’s RS-232 port. A DB9 female
null modem cable such as the 13657 is used to connect the NL100’s RS232 port to a PC’s RS-232 port. The RS-232 cable should be kept at
lengths of ≤ 6 feet to maintain high data throughput rates.
The CS I/O 9 Pin cable is a straight through cable with all 9 pins
connected. Campbell Scientific’s SC12 cable is recommended.
The cable for the RS-485 connection is a 2 twisted pair, 22 awg cable.
CSI recommends the CABLE3CBL-L for use with the MD485s.

WARNING: This is a Class A product. In a domestic environment
this product may cause radio interference in which case the user may
be required to correct the interference at the user’s expense.
2. Preparing to Set Up the NL100/105
The NL100/105 must be set up by configuring one or more of the
communications ports for communication with your datalogger or other
devices in the network. To do this, you must establish a direct communication
link with the NL100/105 using a PC computer. You will need a null modem
cable to physically connect the NL100/105 to the computer. The Device
Configurator or a terminal communication software package (such as
HyperTerminal, which ships with Microsoft Windows operating system
software) is used to configure the settings in the NL100/105.
3
NL100/105 Network Link Interface
2.1 Computer to NL100/105 Physical Connection
An RS-232 null-modem cable is required to establish communication between
the NL100/105 and your computer. One end of the cable is connected to the
computer's 9-pin RS-232 communications port and the other end is connected
to the RS-232 port of the NL100/105. If the null-modem cable does not have a
female connector on both ends, you may also need a female-to-female adapter.
For additional information on null-modem cables, refer to Appendix B.
The NL100/105 requires 12 VDC for operation. This power source can be
supplied by the datalogger's 12 V supply or by a regulated external power
source. When connecting the power leads, the ground lead should be
connected first and then the 12 V lead.
2.2 Communication with the NL100/105
2.2.1 Setup Using the Device Configurator
Campbell Scientific's datalogger support software ships with a utility called the
Device Configurator (or DevConfig). This tool is used to set up dataloggers
and other devices for communication or to download a new operating system.
DevConfig can also be downloaded from Campbell Scientific's web site.
NOTE
The NL100/105 must have at least operating system version 7 to
be compatible with DevConfig's NL100 setup. If your
NL100/105 does not have a compatible operating system, load a
new one in using DevConfig's Send OS utility or u se a terminal
emulation program to set up the device.
To use DevConfig to set up the NL100/105, first connect the NL100/105 to the
computer as noted above and follow the steps below:
1. Remove power from the NL100/105.
2. Open DevConfig.
3. Highlight the NL100 in the list of devices which appears in the left-hand
portion of the window. Select the COM port to which the NL100/105 is
connected from the drop down list box at the bottom left of the window.
4. Press the Connect button and reapply power to the NL100/105. The device
may take up to 60 seconds to respond to DevConfig, and for the current
settings to be loaded into the Settings Editor.
The Settings Editor is the active tab when you are first connected. Settings can
be changed in this window by clicking within a field and entering a new value.
If the value being set has a finite list of choices, a second click within the field
will enable a drop down list box from which to select a valid option.
4
DevConfig has built-in help for each setting, which is displayed at the bottom
of the window. Use this information, along with Section 2.4 of this manual, to
configure the settings for communication in your network. Once the settings
have been defined, press Apply to save the changes to the NL100/105.
You can also use the Terminal tab in DevConfig to set up the NL100/105 using
the menus, as explained in the following section.
2.2.2 Setup Using a Terminal Program
Once the physical connection has been made, communication can be
established with the NL100/105 using a terminal communications package.
The steps below demonstrate configuring the NL100/105 using
HyperTerminal, which is shipped with Windows operating systems.
NL100/105 Network Link Interface
NOTE
The NL100/105 is shipped from the factory with its RS-232 port
set in the ConfMon mode (configuration monitor). Refer to
Section 2.2.3 if the RS-232 port has been set to some other
configuration and direct communication is necessary.
Ensure the NL100/105 has an appropriate power source applied. (Refer to
Section 2.1, above.)
Create a new connection in HyperTerminal. Choose the COM port to which
the null-modem cable is connected, and set the baud rate to 115,200 bps. Most
of the other settings can be left at the default (data bits = 8, parity = none, stop
bits = 1). Flow control should be set to none.
Once HyperTerminal indicates you are connected, press <Enter> a couple of
times to gain the attention of the NL100/105. When communication is
established, the current port settings will be returned, followed by the
NL100/105 prompt line:
NL100/105 (ver, show, edit, defaults, reset, help, bye):
To set up the NL100/105 for communication with the network, go into the Edit
menu (Section 2.4.3 Edit) and complete the appropriate information. Note that
the Ethernet 10 Base-T connection must be configured (Section 2.4.3.5) and at
least one of the other port options.
2.2.3 Establishing Communication Outside of ConfMon Mode
If the RS-232 port has been disabled or set to some configuration other than
ConfMon, communication can still be established with the NL100/105 using
one of two options.
When power is first applied to the NL100/NL105, there is a 0.5-second
window in which communication can be established with the NL100 using the
RS232 port, regardless of the port's configuration. Therefore, if power is
already applied, simply disconnect power and then reconnect it, then attempt to
establish communication within the 0.5-second period. Holding down the
enter key should allow you to hit this 0.5-second window.
The other option is to connect a boot jumper, which bypasses the boot
sequence of the NL100/105. To access the boot jumper, remove the
NL100/105's cover by removing the four screws at the corners.
5
NL100/105 Network Link Interface
The boot jumper is shown in Figure 2 below. The NL100/105 ships with this
jumper connected to only one post. Place the jumper so that it connects the two
posts.
Jumper
WARNING
FIGURE 2. NL100/105 Jumper Placement
When the jumper is in place, open the HyperTerminal connection to the
NL100/105 and power up the device. The prompt "NL100 boot" will appear.
At this prompt, press <Enter> a few times to ring up the NL100/105. If
communication is successfully established, a message will be returned
indicating that the NL100/105 is initialized, along with the jumper setting (1 =
on, 0 = off), the TCP/IP address, Telnet port address, and current
communication configuration. If <Enter> is pressed again, the NL100/105
menu prompt will appear.
After reconfiguring the NL100/105 for communication,
the jumper should be disconnected. If this jumper
remains in place and power to the NL100/105 is cycled
off and back on, the NL100/105 will remain at the
"NL100 boot" prompt and will not boot up. This will
render the NL100/105 inaccessible via remote
communications.
6
2.3 Port Configuration
An important step in configuring an NL100/105 for use is setting up the
communication port(s) that you will be using. Regardless of whether you are
connecting the datalogger (or a communication peripheral) to the RS485 port,
the CS I/O port, or the RS232 port, you must set up the port to support the
mode of communication that will be used for that portion of your network.
The three options supported are explained briefly, below.
2.3.1 TCPSer
When the port is set to TCPSer, it will act as a TCP serial server. Any packet
that is transmitted via the port will be sent using the TCP/IP protocol. This is
the simplest way to set up a port and will work in many scenarios, regardless
of whether the datalogger has a mixed-array or PakBus operating system.
One disadvantage of using this mode when communicating with PakBus
dataloggers is that no PakBus routing can occur via the port. It may also be less
efficient in some instances when communicating with PakBus dataloggers.
2.3.2 PakBus
NL100/105 Network Link Interface
2.3.3 PakBusSer
PakBus is a packet-based communications protocol developed by CSI. It is
used in the CR1000, CR800/850, CR3000, and CR200 dataloggers, as well as
CR10X, CR510, and CR23X dataloggers with a special operating system. One
of the advantages of PakBus communication is that PakBus devices in the
network can communicate directly with and route packets between other
PakBus devices in the network. In addition to the native PakBus packets, other
packet types, such as TCP/IP or ModBus, can be “wrapped” in a PakBus
packet and transferred among the PakBus devices in the network, thus
allowing for various communication protocols within one network.
By configuring a port for PakBus communication, the NL100/105 is set up as a
PakBus router in the network. The NL100/105 can then route packets to other
devices in the network that it has “learned” about through beaconing or
PakBus neighbor filters. When a port is configured for PakBus, the
NL100/105’s PakBus/TCP Server Config option must be enabled or
communication will not take place via TCP/IP with the PakBus devices on that
port.
This option is used only in a PakBus network. In this mode when a packet is
routed out the port, the PakBus framing is removed from the packet. Typically,
the attached device would be one that does not support PakBus communication
(such as a ModBus device).
2.4 NL100/105 Menu Options
The following discusses the menu options and settings that you will see when
connected to the NL100/105 using a terminal emulation package. DevConfig
provides these same options in a graphical user interface.
7
NL100/105 Network Link Interface
The NL100/105 prompt lists all of the available menu options. Only the first
few characters of the main menu options need to be typed – the remaining
characters will be completed automatically. Press <Enter> to execute the
command. Each menu option is explained below.
2.4.1 Ver
Ver returns version information about the NL100/105. The ROM number, OS
version, Ethernet physical address, and some diagnostic statistics are
displayed. Version information may be requested by a Campbell Scientific
Applications Engineer when troubleshooting a communication problem.
NOTE
2.4.2 Show
2.4.3 Edit
The Ethernet physical address that is displayed is a hexadecimal
representation of the address assigned to this device. An Ethernet
address is unique to the specific device to which it is assigned.
This assignment is made at the factory and cannot be changed by
the user. The Ethernet physical address is not the same as the
TCP/IP address.
The Show command displays the current settings for the NL100/105.
The Edit menu option is used to set up the communications link for the
NL100/105. You should work closely with your network administrator to
determine the correct settings for your specific network.
You can progress through the menu options by pressing <Enter>. If you make
a mistake after entering a setting, press the up cursor arrow on your keyboard
to return to the previous setting. All available selections will be listed on the
prompt line enclosed in parentheses, with the current setting displayed in
brackets at the end of the selections (e.g., [disabled]). Help for a setting can be
displayed by entering the ? key and pressing <enter>, or by pressing F1.
8
Once changes have been made and you have come to the end of the prompts
for the communication options, you can choose "save" to put the new settings
into effect or "cancel" to disregard the changes and keep the current settings.
Prior to configuring one or more of the ports for communication (TLink
Config, RS485 Config, CS I/O Config, or RS232 Config) refer to the
discussion on Port Configuration above.
2.4.3.1 TLink Config
This setting is applicable to the NL105 only, and is used when communicating
with a CR9000 datalogger. TLink is an interface used to communicate with a
CR9000 datalogger over an Ethernet connection. A physical connection is
made between the TLink port on the CR9000's 9031 CPU module and the port
marked TLink on the NL105. TLink Config is used to set the TLink
communications port to one of three options:
2.4.3.2 RS485 Config
NL100/105 Network Link Interface
TcpSer - The NL105 acts as a serial server for the TLink port. A serial server
is a device that allows serial communication over a TCP/IP communications
link. When configured as a serial server, there is one parameter to set:
TLink Serial Server Port Number - Enter the port number, in the range of
3000 to 65000, that will be used for TLink communication. The default
port number is 6781.
232-Bridge - The NL105 transparently passes data between the TLink port and
its RS-232 ports. The 232-Bridge configuration has only one setting, RS-232
bps. This is the bits per second (bps) at which the NL105 will communicate
with the device connected to the RS-232 port. This is a fixed rate (i.e., it is not
a maximum baud rate or an autobaud rate). The default is 115k bps.
Disabled - The TLink communications port is disabled.
This option is used to configure the NL100's RS485 port for communication
with an RS485 device. Campbell Scientific offers the MD485 for
communication with its dataloggers via RS485. The port can be configured for
PakBus communication, as a TcpSer serial server, or as a PakSer serial server.
PakBus - This option is used to set up the NL100/105 to communicate with
PakBus devices over the RS485 port. Packets transferred over the port in this
mode are framed as PakBus packets; therefore, any device attached to the port
must be configured for PakBus communication also. When a port is configured
for PakBus, the NL100/105’s “PakBus/Tcp Server Config” option must be
enabled (Section 2.4.3.7) or you will no t be able to communicate with TCP/IP
through the NL100/105 to the PakBus devices on that port.
When configured for PakBus the NL100/105's RS485 port has the following
settings:
RS485 Bps - This option is used to set the bits per second (bps) at
which the NL100/105 will communicate using the RF485 port. The
default value is 38K.
RS485 Beacon Interval - The NL100/105 can be set to transmit a
beacon to a PakBus network via the selected port. The beacon allows
the NL100/105 to determine which devices in the PakBus network it
can communicate with. Note that because a beacon is broadcast to all
devices, it can interfere with other communication in the network
(such as RF), so a frequent beacon may not be desirable. If 0 is
entered, no beacon will be sent; the default beacon is 60 seconds.
RS485 Verify Interval - This is the interval at which a PakBus
communication link will be verified over the RS485 port. If
communication does not take place with a PakBus device within the
verify internal, a packet will be sent to test the communication link.
In most instances, this setting should be left at the default of 0, which
will set a verify interval of 2.5 times the Beacon Interval.
