Icom Ci V Usb Interface Schematic Top -

The Icom CI-V (Computer Interface 5) USB interface schematic typically centers around a USB-to-Serial converter IC, such as the FTDI FT232RL Go to product viewer dialog for this item. Go to product viewer dialog for this item.

Isolation: High-end designs may include opto-isolators to prevent ground loops between the computer and the radio. icom ci v usb interface schematic top

DIY Spirit: Hams often bypass expensive official adapters by building their own using the MAX232 IC (for older serial ports) or the FTDI232RL chip (for USB). A classic "minimalist" schematic uses just three transistors and three resistors to combine those separate computer signals into the single CI-V bus.
