Most of Radio programs are built based on COM serial port of PC computer. But the most latest PC computers don’t have a serial port.
To be compatible with the legacy radio program, we still have to keep using serial port. That’s why we choose to use USB to UART bridge which converts the USB to serial port. FT232R is very reliable industry single-chip USB to UART bridge.
No sophisticate software setting. Very clearly operate from reachable setting on the control panel. It supports CAT with RS232 protocol. So it’s compatible with the most latest transceivers.
