The default port number for RS 232 serial sever communications 1s 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 10 Attribution 10 11 User Manual 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 www campbellsci com 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 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 Reset the NL200 201 to its default settings e 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 Verify you are running the late
