Hi there,
where can I find info on how to configure my COM port?
The aim is to connect with my laptop running WindowsXP.
asked
COM port configuration for BlueSolar 75|15 under XP
Baud: 19200
Bits: 8
Parity: None
Stop bit: 1
Flow Control: None
No successful connection with VictronConnect yet.
I am on pins 2, 3 and 5 for gound of my DE9 on the laptop.
The green LED is on constantly with a blink about every 5 - 10 s or blinking when I disconnect.
Any ideas welcome.
Cheers
Wait. Have you connected the wires directly from the MPPT to the DE9 on the laptop?
The DE9 is RS232, the MPPT is 5V TTL. You need an RS232 to TTL converter like a MAX232 inbetween! Ideally you'd have a digital isolator too, like a SI8422
Something like this will do:
This is my ghetto cable that I occasionally use:
You really need the full 15M :D
I will look into USB to TTL then. Just realized that I have no DSUB on my non-XP machines and VictronConnect for XP is really outdated.
