- RS232, optional RS485 and CANBUS communication ports for connecting
Host IPC/PLC and LED Remote Display.
- With the multitasking mode, the weighing/force measuring process,
alarm output and signal transmission will not be interrupted by
parameter setting and the other operations.
Keypad Operation
If there is not any keypad operation in one minute and it’s not in
the processes of ‘F2 System Calibration’ & ‘F6 Factory
Adjustment’, the controller will return to ‘Main Display Interface’
automatically.
