NL200/201 Network Link Interface
communications is 6783. The default port number for RS-232 serial
sever communications is 6784. The correct port number must follow
the IP address of the NL200/201 in LoggerNet Setup in order for
LoggerNet to communicate through the NL200/201. For example, if
the NL200/201 is configured as a CS I/O serial server, in LoggerNet
Setup, enter the correct IP address of your NL200/201 followed by
:6783 (e.g., 192.168.0.3:6783).
6. If you are unable to communicate with the NL200/201 via the USB cable,
verify that you have installed the latest drivers for the NL200/201. These
can be downloaded from our website at
7. If the NL200/201 is configured as a CS I/O serial server, verify that any
other SDC device attached to the datalogger is using a different SDC
address. For example, if the NL200/201 is configured for SDC7, any other
device attached to the datalogger cannot use SDC7.
8. If communicating over a slow or intermittent connection, it may be
necessary to lower the Maximum Packet Size of the datalogger in
LoggerNet Setup and/or add Extra Response Time to the PakBus® Port in
LoggerNet Setup.
9. Reset the NL200/201 to its default settings.
•
If none of the above steps correct your communication problems, reset
the NL200/201 to its default settings. This can be done using the
Factory Defaults button in DevConfig or by using the Defaults
command in a telnet session with the NL200/201.
10. Verify you are running the latest revision of firmware (operating system).
It is possible that an issue affecting your ability to communicate via the
NL2xx is resolved in the latest version. The latest firmware version and
its revision history can be found a
There is no charge for this download. See Appendix D, Sending a New OS
to the NL200/201, for instructions on downloading the firmware revision
to the NL2XX.
11. If the above steps do not resolve the issue, please call Campbell Scientific,
for help. Before calling, it would be helpful to do the following:
•
Obtain a detailed description of your network setup including TCP/IP
address, port number, PakBus® settings, and other pertinent
information regarding all of the devices in the NL200’s
communication network.
•
Save a copy of the NL2xx settings (in XML format) using DevConfig.
•
Save a copy of the NL2XX event log. This is low-level code that can
be used by Campbell Scientific’s engineering staff to help
troubleshoot the NL2XX. To obtain the event log, the NL2XX must
not be in Bridge Mode. Telnet into the NL2XX using your favorite
telnet program. Once you have logged in, type “eventlog” at the
prompt. Record the date and time that you did this. Copy and paste
the output into a text file.
