Numeric data(6 digits) 21 bits (positive logic)
Polarity 1 bit (LO = negative)
Overload 1 bit (LO = overload)
Decimal point 4 bits (LO = select digit)
GROSS/NET 1 bit (LO = GROSS)
MOTION 1 bit (LO = unstable)
PRINT COMMAND 1 bit (positive pulse, 5ms)
UNIT 1 bit (LO = kg)
Total 31 bits
Note: The output frequency depends on function setting data set in section 5.
Data is output even if the indicator is out of range.
Note: The output is 5V TTL compatible. If interfacing to a PLC or PC ensure that a TTL compatible
input card is used. Additional circuitry is required to interface to 24V inputs.
