Troubleshooting guide

No logger communications
Introduction
This topic covers the apparently total loss of communication between the Weatherlink logger and software
running on a PC or Mac. Partial loss of communication, ie software can talk to the logger to some extent
but, for example, the archive data is no longer downloading successfully, will have different causes to total
loss and again is covered in the separate Archive download errors topic.
Total loss of communications may have a number of causes ranging from trivial to obscure. The notes below
do attempt to cover most causes but inevitably some of the more ‘difficult’ issues need more detailed
description.Try the simple solutions first. In many cases the problem will be fixed without needing to delve
further into the technicalities of the PC/Mac configuration.
The USB logger is, by a considerable margin, the most widely used logger type and most of content here
focuses on the USB type. But the principles will also apply to the Serial logger. The WeatherlinkIP logger
has some specific issues of its own and these are dealt with in a separate WeatherlinkIP topic.
The use of the Davis Weatherlink software is assumed, but the general troubleshooting principles described
should apply to third-party software also. (Some issues arising with third-party programs may obviously be
specific to that program – visit the support forums for the program in question in such cases.)
First steps for troubleshooting logger issues
It is assumed that if your Vue or VP2 station includes a display console (ie you are not solely
using the Envoy console) then all console readings appear normal. Do not try to troubleshoot
logger communications until all console readings are behaving normally.
This topic covers the scenario where a logger has been working satisfactorily for a shorter or
longer period but has then thrown up a problem. If you are having problems getting a new
logger to communicate for the first time then please see this separate New Installations topic
(although it’s always still worth Basic Troubleshooting steps listed below).
