Polarization
When multiple display units (LT4000 Series) are connected, the voltage may drop due to the resistance value in the communication line. Unless the voltage is supplied stably, a communication error can occur.
When a communication error occurrs, set the terminator display unit to [560] and other display units to [Disable].
Settings will be different based on the connected device/PLC or the resistance value of the terminator.
Do not use [5.11K].
