My Setup:

The laptop I use was running Windows 7, but it wouldn't recognize the FTDI adapter drivers. I upgraded to Windows 10 and had no issues. When running the diagnostics software, I would get an error when I would click “Start Read” – the error said to check the COM port or Module number. I immediately thought of a baud rate error on the serial port, but all I had to do was click on “Locate Battery”. This option will tell you the module ID of the single battery you’re connected to, and the application would automagically set the Module ID for you and then you can click the “Start Read”. My module IDs showed as 10 and 16 for my two batteries. After clicking “Stop Read”, I selected a new Module ID under “Change Module ID” and clicked on the “Change ID” button. It asked if I wanted to change Module ID 16 to Module ID 1, which I clicked the affirmative. Bam! Module ID 1. I did the same for the second battery but chose Module ID 2.
