Minimal connections to safely communicate w/BMS


  • What are the minimum connections need to verify operation and communicate via serial interface using the REC USB to RS485 cable?


  • I grabbed this  page snip from page 13 of the Active BMS manual. Manuals are available here:    https://rec-bms-na.com/downloads/  

  • Rick, I have the official REC cable.  Will the BMS power on and be responsive if the only connection is the serial cable?  My battery pack isn\'t quite ready but I want to test the BMS using their desktop app.
