INTERFACE SPECIFICATION

Output

Open collector (Common is connected to the NPN transistor emitter sides)

Output data: 6-digit BCD code, overflow, polarity, motion, strobe

Input

Dry contact (Pulled up to +5 V by a resistor)

Input data: Hold

• In case of negative logic, each terminal is turned on at “1”. “ON” refers to the state that there is power continuity

between the terminal and GND.

Example: The B14 terminal is turned on in NET.

• In case of overflow the digits, 1x10

to 1x10

of the weighing data become “1”.

• Hold-input is fixed at negative logic. All outputs including strobe are held when HOLD input is turned on.
