Icom Ci V Usb Interface Schematic Top [cracked] -

An Icom CI-V USB interface acts as a bridge between a modern computer's USB port and the TTL-level serial bus used by Icom transceivers for remote control. While commercial versions can be expensive, a DIY interface is highly effective and can be built using standard USB-to-UART components. Core Interface Features

The "Top" Interface Strategy: Because computers traditionally use RS-232 serial ports (with separate transmit/receive lines) and modern computers use USB, the "top" schematic for a CI-V interface is essentially a level converter. icom ci v usb interface schematic top

Radio Side (9-pin D-sub):

  • Pin 1: PTT (not used in CI-V)
  • Pin 2: Tx (CI-V): From FTDI RXD
  • Pin 3: Rx (CI-V): To FTDI TXD (Note: For simple cable designs, often ignore or terminate)
  • Pin 4: GND: Common ground
  • Pin 5: SQL (not used in CI-V)
  • Pin 6: RTS (CI-V): To FTDI CTS
  • Pin 7: CTS (CI-V): To FTDI RTS
  • Pin 8: Data (not used)
  • Pin 9: NC (not connected)

  • CI-V requires an "Open Collector" or "Open Drain" output. You cannot drive the line high actively; you can only pull it low.
  • Schematic detail: Connect the TTL Output from the MAX232 to the Base of an NPN transistor (2N2222 or 2N3904). The Collector goes to the CI-V Data line. The Emitter goes to Ground. This allows the interface to pull the data line low to transmit, but float high when idle.

The ICOM CI-V USB interface is a popular project among amateur radio enthusiasts, allowing them to connect their ICOM radios to a computer via USB. Here's a comprehensive guide to help you understand the schematic and build your own interface:

Isolation: High-end designs may include opto-isolators to prevent ground loops between the computer and the radio.
