USB RS232 Converter Serial Interface
After having installed the driver, click on "Start/Settings/Control Panel/System/Device Manage". A USB port will
appear as a COM port in the Device Manager.
The USB RS232 Converter will usually use the lowest available COM port for operation, e.g. if COM port 1 to 3 are
used by other peripherals and applications, the USB RS232 Converter will use COM 4.
The USB RS232 Converter functions identically to a COM port. It can support serial device control requests defined
in the Win32 Communications API.
Updating the mapped COM Port
If the USB RS232 Converter is assigned to a high COM port, e.g. COM 8, but the application does not support it, you
will need to update the mapped port. In the Device Manager, double click the entry "CP2101 USB to UART Bridge
Controller (COM 8)" under the category "Ports (COM & LPT). Select the tab box "Port Settings". Click the
"Advanced..." button and select a lower COM (e.g. COM 2) port which the application will support. Click the "OK"
button. You will see the port mapped to COM 2.
