6. Make sure the IP address and port number entered in
LoggerNet
/
PC400
/
RTDAQ
match the settings in the NL241.
• Note that PakBus® and serial server communications use different
port numbers. The default port number for PakBus communications is
6785 . The default port number for CS I/O serial server
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 NL241 in LoggerNet Setup in order for
LoggerNet to communicate through the NL241. For example, if the
NL241 is configured as a CS I/O serial server, in
LoggerNet Setup
,
enter the correct IP address of your NL241 followed by :6783 (for
example, 192.168.0.3:6783).
7. If you are unable to communicate with the NL241 via the USB cable,
verify that you have installed the latest drivers for the NL241. These can
be downloaded from our website at www.campbellsci.com .
8. If the NL241 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 NL241 is configured for SDC7, any other device
attached to the datalogger cannot use SDC7.
9. 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 .
10. Reset the NL241 to its default settings.
•
If none of the above steps correct your communication problems, reset
the NL241 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 NL241.
11. Verify you are running the latest revision of firmware (operating system).
It is possible that an issue affecting your ability to communicate via the
NL241 is resolved in the latest version. The latest firmware version and its
revision history can be found at www.campbellsci.com/downloads . There
is no charge for this download. See Appendix D ,
Sending a New OS to the
NL241
(p. D-1)
, for instructions on downloading the firmware revision to the
NL241.
12. 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 NL241 communication
network.
• Save a copy of the NL241 settings (in XML format) using DevConfig .
• Save a copy of the NL241 event log. This is low-level code that can
be used by Campbell Scientific’s technical support to help
