SB-2000 USB RADIO INTERFACE
• Connect your computer with USB port. No need serial or parallel port.
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.
• USB to UART bridge by FT232 single chip. USB 2.0 compliant. Full speed.
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.
• CAT, CI/V controller and audio transformer are combined together.
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.

SB-2000 USB RADIO INTERFACE
