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.

4. Indicator communication parameter setting:
(1). Communication parameters
Communication parameters are made up of three groups of parameters, i.e. communication address, baud
rate and communication method.
(2) Steps for setting communication parameters:

Baud rates of serial communication (0~4)
means following baud rates respectively:
600, 1200, 2400, 4800 and 9600 baud rates.
E.g.:1

[ t F 0 ]
Way of serial communication:
0—Continuous send mode, no reception
1—Appointed answering mode
2—Old D2+ continuous communication
format, 8 bits every frame
3—New D2+ continuous communication
format, 9 bits every frame
(See Note 2)
E.g. 0
6 Weighing state Communication parameter setting is
completed
Note 2: In the old D2+ continuous communication format, data is output in form of ASC code with 8 Ⅱ
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 Ⅱ
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 51.07000=51.07000=51.07000…...
