The story of the is one of elegant simplicity in the face of complex technology. While other manufacturers often reinvented the wheel with every new radio, Icom’s standard has remained remarkably consistent since its introduction in the late 1980s. The Birth of a Standard

This path carries data from PC TXD to the CI-V bus. icom ci v usb interface schematic top

CI-V (Computer Interface V) system is a standard protocol used by Icom transceivers for remote control. Because it uses an open-collector, half-duplex TTL-level signal, it requires an interface to convert these signals to levels a computer can understand, such as USB. Core Schematic Components A modern USB-to-CI-V interface typically revolves around a USB-to-Serial UART chip (like the FTDI FT232RL or Silabs CP2102). USB Bridge Chip : Converts USB data into TTL (0–5V) serial signals. Diode & Resistor Combination The story of the is one of elegant
