When use a serial cable, we recommend the installation of a ferrite core on the power supply cable.
Given the presence of the RS232 standard, logic value “0” corresponds to the voltage value +VRS232 (voltage value
b3Vdc and +15Vdc) and logic value “1” corresponds to the voltage value -VRS232 (voltage value between
-3Vdc and -15Vdc.
