Hello everyone,
I bought a second hand Yaesu FT847 and then I was build a isolated interface for DATA IN/OUT port. It works very well but I haven't build null modem cable for CAT control.
I am not familiar with the CAT communication protocol. I use FTDI for PTT control. In FTDI, RX and TX ports are empty and I want to use these ports because I want to using interface one USB cable. Of course, using optocoupler. How can I do it? How should I connect the optocouplers or what kind of circuit should I create?
