The Epson Ports are installed automatically during APD installation.

Note:
The APD communicates through an Epson Port, so do not specify any general-purpose port on the
computer such as COM or USB. Control is not possible through a general-purpose port.
The Epson Ports are numbered with an exclusive name and number (ESDPRTxxx). The numbers
are assigned automatically during installation.
