1.4.2. Checking the COM port on the PC (when using a
communications level converter)
Loader running on the PC uses the RS-232C communications port (COM) to interface with
inverters.
When an
RS-232C / RS-485 converter
is connected to the PC, check what COM port number
(COM#) on the PC is assigned to the RS-232C / RS-485 converter.
To use the USB interface, select a
USB / RS-485 converter
that functions as a virtual RS-232C
communications port (COM). When a USB / RS-485 converter is connected, Windows
automatically assigns a free COM port on the PC to the converter. To check the assignment,
follow the procedure below.
