be ASCII code letter for sending, for example, Xor checking four higher bit is B. With 37h added, it is
42h, i.e. letter B in ASCII code for sending out.

(1). Communication parameters
Communication parameters are made up of three groups of parameters, i.e. communication address, baud
rate and communication method.

Note 2: In the old D2+ continuous communication format, data is output in form of ASC code with 8
bits in every frame (including the decimal point). Lower bits of the data are sent at first and then
the higher ones. The frames are divided by "=". Data being sent is the net weight (i.e. the value
displayed on indicator), for example, when the value 70.15 is displayed, the indicator
continuously sends out 51.0700＝51.0700＝51.0700.......
In the new D2+ (300 tons) continuous communication format, data is output in form of
ASC code with 9 bits in every frame (including the decimal point). Lower bits of the data are
