Icom Ci V Usb | Interface Schematic Top Upd

CI‑V uses (one‑wire bidirectional data). The USB side (UART) is standard TTL (non‑inverted). So you need:

USB TTL TxD ---- 10k ----- Base of NPN Emitter - GND Collector ---- 1N4148 ---- CI-V data line | +--- 4.7k pull-up to 5V CI-V data line ---------------------------------------------- USB TTL RxD (with internal pull-up enabled) icom ci v usb interface schematic top

Building a DIY Icom CI-V (Computer Interface V) USB interface is a popular project for enabling rig control on transceivers that don't have a native USB port. The interface functions by converting standard computer logic levels into a single-wire, half-duplex bus that communicates with the radio at TTL (0-5V) levels Interface Overview The CI-V protocol uses a 3.5mm mono phone jack This likely refers to the Icom CI-V USB
