NOTE: The Data Parity and Baud Rate must be the same for all the devices connected on the local RS-485 network, otherwise
the exchange of data will generate communication errors. If the BMS card has the incorrect data parity or baud rate,
then the Status 2 LED (white) will FLASH slowly (once every 2 seconds). See Section 04.07 for BMS Troubleshooting.
