Which USB to RS232 converter please?
I've now bought FOUR different USB to RS232 adapters so I can update the firmware on my TS MPPT-60-150's and so far NONE of them have worked. All that's available in my part of the world is cheap Chinese crap.
So, I need to order off Amazon.
Please could someone let me know which model USB-RS232 converter actually works with the TS-MPPT-60-150 so I can order it and get my firmware upgraded. It's driving me nuts!
Thanks in advance for the help.
