Steve87 Posted April 29, 2023 Share Posted April 29, 2023 Hi @MorphZanyou need to plug into the RS485 BMS port. Pins 1 & 2 RS485B & A respectfully. The other ned plugs into the Pi via USB. Quote Link to comment Share on other sites More sharing options...

Steve87 Posted April 30, 2023 Share Posted April 30, 2023 How are you crimping ? & Show us a pic of the ports you have. Quote Link to comment Share on other sites More sharing options...
MorphZan Posted April 30, 2023 Author Share Posted April 30, 2023 The ports are the same as in the image you posted. I believe the cable I was given and told would work is incorrect. UGreen USB2.0 to RJ45 Consol 1.5m Cab -Black https://www.takealot.com/ugreen-usb2-0-to-rj45-consol-1-5m-cab-black/PLID53646762 Quote Link to comment Share on other sites More sharing options...
Steve87 Posted April 30, 2023 Share Posted April 30, 2023 There is a reason I gave you the pin outs. You need only 1 & 2. The others are not required. So you can either spend on the solar assistant cable & spend R500 bucks or you can use a crimping tool & actually make up the cable. I'm sorry to say that these out the box cables are HIIT & miss. You need a RS485 to USB converter, RJ45 crimping ports & a suitable RJ45 crimping tool. Maybe just buy the cable for R500...Where are you based. If in JNB give me a shout.

MorphZan Posted April 30, 2023 Author Share Posted April 30, 2023 (edited) Based in Cape Town but much appreciated. It's a once off cost so will purchase the cable from SA and be done with it. Just to confirm though the cable should be connected to the BMS 485 port as in this image?

Steve87 Posted April 30, 2023 Share Posted April 30, 2023 Yes the BMS RS485 port. That is the port that the Solar assistant makes use of. Raiden2912 and MorphZan 2 Quote Link to comment Share on other sites More sharing options...

MorphZan Posted May 6, 2023 Author Share Posted May 6, 2023 @Steve87 Again thank you for all your time and assistance - very much appreciated.... Cable arrived and system is up and running 100% - I am waiting on a Pi Zero as I want to see if it works on there.
