10.1 MT Standard Continuous Output
A checksum character can be enabled or disabled with continuous output. The data consists of 17 or 18 bytes
as shown in the standard continuous output.
Non-significant weight data and tare data digits are transmitted as spaces. The continuous output mode
provides compatibility with OHAUS products that require real-time weight data. the standard continuous output.
Table 10-1 shows the format for the standard continuous output.
Character 1
Data
Continuous Output Format Notes:
1. ASCII Start of Text character (02 hex), always transmitted.
2. Status bytes A, B and C. Refer to Table 10-2, Table 10-3, and Table 10-4 for details of the structure.
3. Displayed weight. Either gross or net weight. Six digits, no decimal point or sign. Insignificant leading
zeroes are replaced with spaces.
4. Tare weight. Six digits of tare weight data. No decimal point in field.
5. ASCII Carriage Return <CR> character (0D hex).
6. Checksum, transmitted only if enabled in setup. Checksum is used to detect errors in the transmission
of data. Checksum is defined as the 2's complement of the seven low order bits of the binary sum of all
characters preceding the checksum character, including the <STX> and <CR> characters.
Table 10-2, Table 10-3, and Table 10-4 detail the status bytes for standard continuous output.
