X2 – Serial Interfaces RS-232 (COM 3) and RS-485/RS-422
(COM 2)
The RS-232-interface and the RS-485/RS-422 interface are combined in one
connector. Both are DC coupled with the power supply of the device. They are
generally used for communication (service devices, modem operation, etc.).
Both interfaces may be operated together.
The connected data cable must be shielded.
