(1) The SSI protocol haven't CRC check. Recommend to use BISS-C Standard with the same hardware instead to improve reliability.

(2) The BS protocol uses the completely standard BISS-C protocol format.

(3) The T485 protocol optional output parameters are 17M or 17BM.

(4) The ordinary multi-turn's multi-turn data is only valid when the power is turned on. Counting starts from zero after the power isturned off and then on again.
