7.0 ATTACHMENT
The balance use RS 232 UART signal, one frame consists of 10 Bit.
Bit1: Start Bit Bit2-Bit9: Data Bit Bit10: Stop Bit.
The format of printing mode (mode 4) is as follow:
Add: ANO.1 : Weighing times
n/w: 0.00001kg : net weight
The format of continues transfer mode (mode 1) is as follow:
All data is on ASCII code except the start bit.

Note: Checksum of high-half byte and low-half byte less or equal to 9, adding 30H, then the data trans-
fer as number of ASCII code.
Example: Checksum of high-half is 6, adding 30H, it come up to 36H, data will be transferred as 6 of
ASCII code.
Checksum of high-half byte and low-half byte is over 9, adding 37H, the data transfer as alphabet of
ASCII code.
Example: Checksum of high-half is B, adding 37H, it come up to 42H, the data will be transferred as B
of ASCII code.
