CI-V requires an open-collector driver.
(e.g., 1N4148) is often placed between the TXD line and the CI-V bus to prevent the chip from "fighting" incoming signals when not transmitting. pull-up resistor icom ci v usb interface schematic top
Building a DIY Icom CI-V USB interface is a popular project for amateur radio operators looking to avoid the high cost of official cables like the Icom CT-17 ~40×20 mm (e
The ICOM CI-V USB interface works by converting the CI-V signal from the ICOM radio to a digital signal that can be transmitted over USB to a computer. Here's a step-by-step explanation of the process: ~40×20 mm (e.g.
