Icom ci v cable pinout1/15/2024 ![]() ![]() ![]() Some other similar projects, using Arduino as a CI-V interface: The 10 k ohms potentiometer is used to attenuate the signal output (which is too high for most analog meters) and calibrate the analog meter to get a full scale reading with a powerful local signal (+60 dB). The +12 V DC to the S-meter is not necessary it could be used to power meter backlight or any other optional features. You can use the CI-V "00" universal address on some Icom radios, making this converter compatible with any Icom radio, without changing the CI-V address in the code.įerrites are installed on input & output cables to eliminate RF induction. This project is designed for an Icom IC-7000 transceiver, but it can be adapted to any Icom radio with a CI-V port. If you don't have an Antenna Tuner connector, you can use a PC computer power supply connector, and trim it with cutters to fit the Icom tuner connector. An external DC power source can also be used. ![]() If your Icom does not have a tuner port, you can use any other port or connector that provides a +12V output (at least 200 mA). It is powered by the Antenna Tuner port on the Icom radio. This circuit uses an Arduino Uno or Nano to send a CI-V command to an Icom radio to ask for signal information, read the answer, convert it and display it on an analog output, where you can connect an analog (Arsonval) S-meter. ![]()
