1. Introduction The NL100 and NL105 Network Link Interfaces are devices used to communicate with Campbell Scientific dataloggers using an Ethernet 10 Base- T communications link. The NL100 includes a CS I/O port (see Appendix A) and an RS-232 port for communication; the NL105 adds a TLink interface for communication with a CR9000(C) system.
≤ 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. Compliance The NL100/105 is encased in metal and meets requirements for a Class A...
NL100/105 Network Link Interface 2.2 Communication with the NL100/105 2.2.1 Establishing the Initial Communication Once the physical connection has been made, communication should 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 Jumper 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...
NL100/105 Network Link Interface Version information may be requested by a Campbell Scientific Applications Engineer when troubleshooting a communication problem. The Ethernet physical address that is displayed is a hexadecimal NOTE representation of the address assigned to this device. An Ethernet address is unique to the specific device to which it is assigned.

NL100/105 Network Link Interface 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. 2.3.3.2 RS485 Config Currently there are no dataloggers with RS485 ports, or RS485 to RS-232 interfaces for a datalogger's CS I/O port.
Page 14
NL100/105 Network Link Interface TcpSer - This option configures the NL100 to act as a TCP/IP based serial server when communicating with the datalogger over its CS I/O port. This is the most common setup option for this port. CS I/O SdcAddr/bps - This option is used to set up the CS I/O port to communicate with the datalogger as an addressable SDC device or a modem enabled device.

NL100/105 Network Link Interface CR10X, CR510, CR23X, 21X, and CR7 dataloggers ship with an NOTE array-based operating system. Array-based dataloggers do not support the PakBus communications protocol. Therefore, you cannot communicate with them over a port configured for PakBus. However, the CR10X, CR510, and CR23X dataloggers can be special-ordered with a PakBus operating system.
Page 16
NL100/105 Network Link Interface RS-232 bps - This is the bits per second (bps) at which the NL100/105 will communicate using the RS-232 port. This is a fixed rate (i.e., it is not a maximum baud rate or an autobaud rate). Note that the CR10(X) and the CR510 can communicate at a maximum baud rate of 9600 bps, so to communicate with one of those dataloggers, this setting must be 9600 bps or less.

NL100/105 Network Link Interface Clock Neighbor Node ID - In a PakBus network, a "neighbor" is another PakBus device that the NL100/105 can communicate with directly (e.g., it does not have to route data through another PakBus device to reach the neighbor).
NL100/105 Network Link Interface alphanumeric characters and is case-sensitive. This security measure is implemented to help prevent unauthorized users from gaining access to the NL100/105 device. 2.3.3.12 Serial Server Watchdog If no communication is detected for a specified number of minutes, the NL100/105 will drop the communications link.
NL100/105 Network Link Interface Telnet session password: [nl100] Serial server watchdog (minutes): [2] This option is different from the Reset menu item. The Default menu item resets the NL100/105 back to the factory defaults. Reset reboots the device using the last-saved configuration. After the NL100/105 reboots, it may take a few moments to reestablish communication.
Some of the communication links require additional peripherals or cables that can be purchased from Campbell Scientific. In some cases, a standard RS-232 9 to 25 pin or 25 to 25 pin cable is required. RS-232 cables can be purchased...
NL100/105 Network Link Interface FIGURE 3. Typical NL100/105 Setup in LoggerNet 3.2.1 Direct Connect from the NL100/105 to a Datalogger Either the CS I/O port or the RS-232 port can be used to directly connect a datalogger to the NL100/105. Cabling or additional peripherals are required as listed below.
SC12 cable. 3.2.2 MD9 Connection from NL100/105 to Datalogger Campbell Scientific's MD9 Multidrop Interface can be used to connect one or more dataloggers to the NL100/105 via the NL100/105’s RS-232 port. A multidrop network is capable of addressing up to 254 dataloggers, but the...

LoggerNet Setup for NL100/105 to MD9 to Datalogger Connection 3.2.3 RF Connection from NL100/105 to Datalogger NL100/105 to radio frequency (RF) modems to datalogger connections allow wireless communication to remote dataloggers stations over a TCP/IP network. Up to 254 datalogger sites can be addressed in an RF network.
NL100/105 Network Link Interface FIGURE 5. LoggerNet Setup for NL100/105 to RF to Datalogger Connection Refer to Campbell Scientific's Radiotelemetry Network Instruction Manual for more information on setting up RF stations. 3.2.4 Short Haul Modem Connection from NL100/105 to Datalogger The use of Short Haul Modems (SRM-5A, SRM6-A) allows a connection to a datalogger via TCP/IP to a twisted pair cable.
NL100/105 Network Link Interface 3.2.5 Phone Modem Connection from NL100/105 to Datalogger A Hayes-compatible phone modem can be connected to the NL100/105 to allow a TCP/IP to phone link between a computer and a datalogger. The phone modem should be connected to the NL100/105's RS-232 port using an appropriate RS-232 serial cable.
NL100/105 Network Link Interface 3.3 NL100/105 to Datalogger Connections - CR9000/CR5000 3.3.1 Software Setup As an alternative to LoggerNet, PC9000 software (version 3.5 or higher) can be used to communicate with the CR9000 and CR5000 dataloggers via the NL100/105 and a TCP/IP Network. To configure the software for communication, choose the Tools | CommLink menu option.

Appendix A. CS I/O Port The CS I/O port is Campbell Scientific's input/output port. It is not a standard RS-232 pin-out. The following table provides pin-out information on the port when connected to a datalogger. Signal Name Type Description 5 V (supplied by the...

Appendix B. Null-Modem Cable A null-modem cable allows communication between two similar devices. It is sometimes called a crossover cable, because the transmit and receive lines are crossed so that the two devices can communicate. An RS-232 null modem cable usually also crosses other handshaking lines.
Page 31
Appendix C. 10 Base-T Cabling The cable that runs from the computer to the NL100/105 should be a Category 5 twisted pair cable. If the NL100/105 will be connected directly to the computer, a crossover cable should be used. If the NL100/105 will be connected to the computer through a hub, a straight through cable should be used.

PakBus - PakBus is a packet-based communications protocol developed by Campbell Scientific. One of the advantages of PakBus is that other communications protocol packets, such as TCP/IP or MODBUS, can be "wrapped" in a PakBus packet and transferred among PakBus devices in the network, thus allowing various communication protocols within one network.
