AND Weighing Indicator AD-4401, Инструкция по эксплуатации

Страница: 63 / 90

61
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
0
to 1x10
5,
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.
