The physical bus operates at standard TTL logic levels (0V for low, 5V for high). Modern USB ports operate on serial data protocols, meaning an interface must bridge the USB interface to this 5V single-wire TTL bus. 2. Core Components of a USB CI-V Interface
Because PCs no longer feature native serial ports or raw TTL pins, we must convert USB data into a single-wire TTL format. Technical Block Diagram A reliable DIY interface consists of three core stages:
Ensure the hex address matches your radio's internal menu setting (e.g., 94h for the IC-7300).
If you do not want to solder surface-mount ICs like the FT232RL, buy a cheap . Connect the board's GND to the 3.5mm jack Sleeve .
