Battery not recognised by GX System (Pylontech US2000C, Victron MultiPlus 2 3000 GX, 2xMPPT)

Hello Community,

build a new offgrid system with Victron & Pylontech. Started with on Pylon US2000C to get it running but the Battery is not recognised by the Victron system. First we had the wrong Cable (Typ B) and in this case the battery was visible in RemoteConsole. Problem was that voltage reading between Victron and Pylontech was different. After changing it to Typ A Cable between GX and Pylon the reading was still wrong, so we made a factory reset of GX module and build up from scratch. Now the battery is not recognised at all. Firmware is up-to-date for all Victron components. Firmware of US2000C I cannot see. Any ideas?

Ok, found the issue. GX device. Menu path: Settings → Services → VE.CAN port.
CAN-bus speed was set to wrong value. Correct value is:

Excellent, very helpful ... I also work with Victron systems and Pylontech Batteries but never had that issue, actually I was reading your post for giving some ideas but I would have never thought of the error you had. Thank you for posting your solution
