Input logic
BUSY
Data will be held during ON (when
connected to input signal GND).
Switch
input
Switch will be performed with ON (when
connected to input signal GND).
- All input, no voltage contact or open collector
(connected to 5 V internally)

I/O timing chart
The factory setting of Tstr (Strobe pulse width) is approx. 10 msec. The BCD data
should be acquired approximately 5 msec after the strobe changes from ON to OFF.
* -“All input pins ON”, is the condition, where all input signals are connected to
GND (Pin 3).
- When inputting RE-ZERO for 100 msec, the weighing instrument
maintains the re-zero state.
