Icom Ci V Usb Interface Schematic Top __top__
: Use a 3.5mm mono jack . The combined TX/RX signal goes to the Tip , and the module's GND goes to the Sleeve . Key Build Tips
Connect a 4.7kΩ to 10kΩ resistor between the CI-V Tip and the 5V VCC pin on the USB module to ensure the bus idles high. Key Components List USB-to-TTL Module: FTDI FT232RL modules are highly recommended for driver stability. Diode: or similar high-speed switching diode . Resistor: 4.7kΩ (standard for CI-V). Plug: 3.5mm (1/8") Mono Phone Plug. Cable: Shielded audio cable to prevent RF interference. Software Setup icom ci v usb interface schematic top

: Because the CI-V bus is a single-wire system, the unidirectional TX and RX lines from the chip must be combined. This is often done using:
. These chips handle all USB protocol tasks and provide TTL-level Transmit (TX) and Receive (RX) signals.
