Yet Another ICOM CI-V Interface | | |

This page describes my home-built ICOM CI-V interface. In order to connect most all ICOM radios to a computer, an additional interface is required. The interface bridges the gap between the RS-232 electrical levels used by the computer serial port, and the open collector shared bus used by the ICOM radios. The interface, therefore, is not much more than a level converter.
