[QUOTE="Oldman22, post: 545479, member: 36003"] Not quite solar pv but associated. I can with a laptop and the correct lead with is RS232 from an RJ11 port on the battery to a USB conversion male plug, log into pBMS tools and realtime read my Battery stats. [ATTACH alt="1684921464511.jpeg"]15486[/ATTACH] My battery is in the garage and I want to read it from the comfort of my lounge, so I thought no problem just run a usb male to female lead through the wall to the garage and plug the USB end of the serial lead into the extension, its usb and that's good for 10mtr without loss. So I pre tested a 3mtr USB male to female lead by sticking a memory stick on the end it read fine so lead is ok. What I failed to do was put the serial lead onto the 3mtr usb lead and try reading that! Ran the extension through the wall, connected my pc to one end and the serial usb to the other, plugged the RJ11 into the battery and computer says[I] Unrecognised attachment in usb port.[/I] Oh dear me. So just in case I tried another 3mtr lead, same result. Tried with my laptop in the garage and adding the 3mtr lead gives the same error, without the extension all is fine. So can I assume the output signals from the RS232 USB lead are so boarderline low as to be lost over 3 extra mtrs? [/QUOTE]
