Hi all

I replace my inverter a while back and connected to the RS232 to USB port. Everything was working fine. It then just stopped working. I noticed at that time my windows had updated. I am a programmer and wrote my own windows service to monitor and store data. It was working well. I tested my USB to RS232 using a loop back plug and it is fine. The software just will not connect anymore. Please has anybody else had this issue or can point me in the correct direction or even a way to test the inverter to make sure its not faulty. I don't believe it is.

TIA

Hi Warren,

Have you tried connecting the inverter to the software that was supplied with it ?

 

 

I believe that Full Circle are genuine (rebranded, as they all are), not clones.

My guess is that the Windows update broke your Windows service somehow.

Assume the loopback test was done on the same PC and USB port as used for the inverter connection? (pretty sure you would have done it that way...but no harm in asking). 

The obvious uninstall and re-install the USB controller (device manager) ? 

Another too obvious one  - antivirus/firewall present/updated too?

Also too obvious (or practically not possible)... a different computer running standard software or your custom service connected to the inverter?
