This is the diagram I used I used one of these connectors below. I had a old phone cable with the 4 wires and I crimped a rj45 on the one end so I did not need to solder the connector https://www.comx-computers.co.za/ADA023-Unbranded-RS232-9-pin-Female-Serial-to-RJ45-Buy-p-171417.php Hope this helps

Hi, I did make a serial cable for the console port on the Pylontech U3000 that plugs into a USB to RS232 convertor. Images to make the cable are in an earlier post. At first I could not get it to work. Checking on this forum and in the pylontech manual I found on this forum the baud rate of the USB to serial must be set to 1200 in windows. I hope this info helps the next guy trying to connect the Pylontech through the console port. It all works 100%. This is really great software
