Hi,
I'm trying to connect to the MPPT 75/15 via RS232. According to the manual the VE.Direct interface should be outputting information in text mode. While I am getting bursts of data every second and there is definitely a structure to it, I just can't seem to make any sense of it. I can't even find a single newline or tab character, which should be present in all text mode transmit blocks.
Is there something I'm missing or could the unit simply be defective? I'm using the serial settings given in the manual:
baudrate: 19200
data bits: 8
parity: none
stop bits: 1
flow control: none,
though I've tried everything else as well.
Here is a sample of the output in hex format synced to 0x79 since it seems to divide the stream into somewhat regular looking chunks:
