“The download progress bar stops before it reaches 100% with an error message.”

If the progress bar stops, there is a communication issue between the logger and LogTag Analyzer, and LogTag Analyzer subsequently retries to get the correct information from the logger. In most cases where the communication is not successful this will be followed by an error message “Internal error $4” or “LogTag failed to respond [20]”. Please see Error Messages below for assistance regarding these error messages.

You should also disable all communication ports currently not in use by selecting “Edit – Options – Communication Ports” and removing the check marks for the unused ports.
