Flexradio 6700 and Acom 700s amplifier

edited June 2021 in Peripherals & Station Integration
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...

    Hi,


    I have a Flex 6500 and and Acom 700S, plus the O40T ATU / antenna switch. In reply to the above comments, I have found the Acom controller software works much better than director for the 700S

    I noticed recently the atu tune function no longer works as it should, has anyone else had similar issues.

    In order to get the Acom ATU to tune, I have to set the cat feature to off in the amplifier, and then tune manually.

    Hello everyone, I work with a Flex 6400, an Acom 1200s and the 04 tuner. The combination 6400 and Acom 1200s works very well with the CAT interface! There were problems when connecting the tuner! When controlling the tuner via the Acom 1200, the 6400 was controlled directly. The flex was set to 30W and went on the air...without power! After that, any frequency was set on the TX and the Smart SDR software froze. A restart has not been possible since then :-( Does anyone have an idea 73

    Hi!

    @Luis You have to perform a factory reset with the Flexradio.
    I went into the same trouble. Only resetting to factory defaults made my Flex work again.

    I am battling the same issues here looking for any way to get the acom amp+ 04at to tune "automatically" by pressing the tune button on the amp, and let the cat request the tx.

    I have the cat cable working.- all bands switch, etc.

    (someone ask for a remote on - you can do that by attaching pin 11 on your cat cable to 5v from a usb plug on your pc :) - I used a 200 ohm resistor in case of any shorts, mis wirings - works like a charm, pc on, amp on (or the flex radio usb port also will work to control it. - it is OK to leave the signal on constant, even though the manual says pulse )

    I can manually tune the 04at turning off the cat as described - works ok, but painful.

    I want to have an automated way.

    I tried a test tone from a RTTY program, set up in dax, get the signal, and rf will come in tune mode.

    it sends rf to the amp, but I don't know if the modulation is affecting it, but it never tunes. it could be the ptt line on the amp is never activated when the amp requests the tx? I found if you don't have a ptt sig, it wont manually tune (found this when i forgot the check mark in the tx band settings).

    anyone have any luck using this method to get it to tune automatically?
