Try disabling the plugin and renabling it. Try it a couple of times. What port is the configuration screen on the plugin reporting as connected to the automation module.
I found it easier to connect serial (automation module) to USB on your Windows PC. Have you got a serial to USB cable to try it out.
As Varsc mentioned make sure you have 9600 8 bits and odd parity. Sounds like a protocol issue.If all else fails reinstall the plugin and cycle the panel by disconnecting the AC and disconnecting the battery.
