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 Base-
T 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 CR10XTD-
PB, 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.
