BCD parallel data output interface [BCO]
Parallel interface to send weight data to a printer, external display or various sorts of
data processing equipment.
The Input/Output singles are photocoupler-insulated from the internal circuits.
Output signal
: Weight data (5 digits)
Output logic
: Positive/Negative selectable
Output circuit
: Open-collector
Input signal
: Logic switching, hold, output data selection
Input circuit
: Operated by a contact or an open-collector circuit
(Ic=10mA min.)
D/A converter [DAC]
Weight values are output as converted to analog signals of current.
Zero output weight value and full scale weight value can be set.

RS-485 communication interface [485]
Compared with the RS-232C, longer-distance communications can be carried out.
Furthermore, two or more F701-Cs can be connected in parallel by setting ID numbers.
