Flexradio 6700 and Acom 700s amplifier

Robert PA5A · October 2020

I own a Flexradio 6700 and an Acom 700s amplifier with an Acom O4AT antennatuner.
Bought and made several USB to serial cables to make a CAT connection, but nothing will work. Changing the frequency on the Flexradio wil not result in changing the frequency on the Acom amplifier.
I've seen the movies on the internet how to connect and config the amp and the flex, RS232, BCD etc. they don's work. The usb cable works fine according the flex (HI),
My question: does anyone have a configuration above and does the CAT connection work?
PSE tell me how.

I use a 600s and assume the 700s would be similar. I have followed this procedure:

Be sure to use a FDMI USB to serial converter!

I'm running a 6600M and CAT controlling my Acom 700S which in turn controls my Acom 04AT tuner. Let me know how I can help.

Problem is solved, tested a new cable with different PIN connections

Good to see the problem was resolved with a new cable wired to the right pins

Is it possible for the 6600 radio to power the ACOM amp on and off ? via the RS232 port I guess as the 6600 radio is turned on and off the ACOM amp also powers on and off / or is there another way

I have tried ACOM Director Plus and it can turn the ACOM amp off but not back on

Paul, checkout Acom Director Plus software. A Flex was not designed to be a computer providing overall control of other devices. The Flex architecture expects some other computer running Windows, MacOS, etc. to control the Flex and other station accessories...
