6.1.5 Determination of the COM interface (Professional)
For all "professional" versions the COM interface must be entered in WinPCNC (s. Page 17).
Some computers have multiple COM interfaces so that the right one first has to be found out. If the
interfaces are not marked on the PC, you need to find out which interface you have connected to the
control.
If the PC has no COM port, it is possible to work with a USB / Serial converter . This adapter then
emulates a COM interface. (see below COM4)
Art. 400305 Digitus DA-70156-VPR2.0 USB to Serial Converter
In the Device Manager of the PC all available interfaces are listed.
Standard interfaces, see Connections
(COM & LPT)
Here you can see, for example, a PC with three COM ports
(COM1, COM2, COM4).
The machine is connected in this case to COM4.
In WinPCNC you must then select COM4 (see 6.1.6).
The COM4 interface is provided via the USB / Serial
converter. This is indicated by the entry USB Serial Port
(COM4).
