I have purchased a ir->serial port cable for reading from the IR-port on electrical meters.
With the included program meter.exe, I can only get this:
C:\extra\Downloads\meter>meter -port=com3 olcdtool version 1.00 Opening: com3, baud: 300 Meter ID: /LGZ4ZMF100AC.M29
then what looks like a question mark in a square.
But no data.
Any clues? Can the power company turn off the port so it sends no data?
Here is the reader software: https://www.dropbox.com/s/qjhykezcojkt3g7/meter.zip?dl=0
