Re: CAT Control Options
If you ever want to control your Icom radio via the ci-v port using atoggle quoted messageShow quoted text
Raspberry Pi running your own linux scripts, I have figured out how to
turn on the Pi serial port (header pins 8 and 10) and send ascii/hex
data to the radio. The ci-v bus is the same as the old com port
(RS232) except the voltage levels are 5 volts and ground. I would be
happy to share my scripts and what I have learned about the interface.
One of the GPIO pins could be used for PTT on the radio.
Here are some notes about turning on the serial port on the Raspberry Pi.
Here is a diagram of my interface to a chinese transceiver board.
Similar wiring could interface to an Icom radio.

I look forward to learning what you learn on making the link from the Pi
