Appendix 1
.
All data are the ASCII code. Each frame data is formed by 10 digits. The first digit is starting digit,
th
the 10
digit is the stopping digit and the 8 digits in the middle are the data digits. The
communication format is as follows:
I.
Continuous Sending Mode:
The sending date is the current weight of indicator (Gross weight or Net weight). Each frame is
formed by 12 groups of date. The format is as follows:
No. X Byte
1
02(XON)
