Pin 3 TXD is used for the output of RS232
Pin 5 GND is used for the ground connected
Pin 9 CTRO_O is used for the output of the alarm signal
4.2. The communication method is continuous sening,the data format
is:7 bits for weight value(low data in front of high data),1
bit for sign.For example:
The weight value is 200.0KG,the communication data will
be:=0.002000
The weight value is -200.0KG,the communication data will
be:=0.00200-
