Continuous Transmission (mode 1) & Stable Transmission (mode 3)
• All the data is in ASCII code except the Start bit. This is the format:
Byte Notes Contents
1 Start of text 02H(STX)
2 Indicator Add A-Z
3 Stable Status 0 stable / 1 unstable
4 Data Sign +/-
5~10 Data Sign 6 Byte (From high to low)
11 Decimal From right to left (0-5).
12~14 Unit Code A-Z
15 Power 0 normal / 1 low battery
16~17 XOR Checksum 2 Byte A-Z
18 End of text 03(ETX)
Note: Checksum of the high-half byte and low-half byte less or equal to 9, adding 30H, then
the datas transfer as number of ASCII code. Example: Checksum of high-half is 6, adding
30H, it comes up to 36H, datas will be transfered as 6 of ASCII code. Checksum of high-half
byte and low-half byte is over 9, adding 37H, the datas transfer as alphabet of ASCII code.
Example: Checksum of high-half is B, adding 37H, it comes up to 42H, the datas will be
transfered as B of ASCII code.
When the weighing is stable, the next datas transfer will be done only after the weight on the
scale is removed and the scale goes back to 0.
Print Transmission Mode (mode 4)
• After the weighing is stable, press the [UNIT/PRINT] key to print the
data once. The format will be:
NO. 1 ; NO. 1 : Weighing times
Net: 0.0001kg Net: Net weight
Response Transmission (mode 2)
• PC transfers the order to the scale and the scale operates accordingly
after it receives the order.

1. Zero(H) : The order bit 0x48(‘H’) is for zeroing once.
2. Tare(I) : The order bit 0X49(‘I’) is for tare once.
3. Units shift(L)
