The following picture shows an example of connection between the device and a personal computer using an 8 pin serial
RJ45 male connector and a 9 pin female connector.
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 a voltage level of between +3 Vdc and +15
Vdc and logic value "1" corresponds to a voltage level of between -3 Vdc and -15 Vdc.
