Continuous Output Mode
Printout string for g, kg, lb, oz units:
Field
Weight space Unit space Stability space G/N/T Space
Length 8 1 3 1 1 1 1 1

The printout string has a fixed length of 17 characters.

Each Space field is a delimiting space used to separate the other fields.

The Weight field is 8 right justified characters. If the value is negative, the '
‐
' character is printed at the
immediate left of the most significant digit.

The Unit/Mode field is 3 left justified characters.

The Stability field is 1 character.

The G/N/T field is 1 character. 'G' is printed for a gross weight. 'N' is printed for a net weight.
Note: The Termination Characters Carriage Return and Line Feed are appended to the printout.
MT Continuous Output Mode
Continuous Output can be assigned to COM1 or COM2. A checksum character can be enabled or disabled with
continuous output. A data string will be output approximately 4 times per second for baud rates above 4800 baud. If
a baud rate below 4800 is selected, the output rate will be slower. At 300 baud, the output rate is only
approximately 1 per second. The data consists of 17 or 18 bytes as shown in Table C-1.
Non-significant weight data and tare data digits are transmitted as spaces. The continuous output mode provides
compatibility with MT products that require real-time weight data. Table C-1 shows the format for the standard
continuous output.

Continuous Output Format Notes:
1. ASCII Start of Text character (02 hex), always transmitted.
2. Status bytes A, B and C. Refer to Table C-2, Table C-3, and Table C-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.
