USB cable problem

Hi All,

yesterday I got the LL tuner connected to the controller. The controller is connected to the Flex-6700 with a USB-RS232 cable. After configuring the USB cable in SmartSDR, the controller should read the Flex frequency in order to switch the memories of individual band segments. Yesterday it worked for a short time, but after restarting the computer I can not restore proper operation. There are 3 types of trx in the controller menu. Icom, Kenwood, and Yaesu. It is also possible to choose the address of the radio. But I don't know what address to choose for Flex. The speed is 9.6 as for the USB cable. The controller should work after CAT. I do not know if it is enough to configure the USB cable as CAT or do I need to add another port in CAT? Maybe the problem is the USB-RS 232 converter? I changed 3 and it still doesn't work. I am asking for help in solving my problem.

    Can you explain a bit more of the hardware you are using please. I can't quite understand your setup. Also, rebooting your computer will not make any difference to the commands being sent by the radio USB / RS232 port to the tuner.

    The radio outputs Kenwood RS232 at your defined baud radio. It is an outbound message only, you can't send commands to the radio.

    If you look at SmartSDR you can see the commands being sent via the LOG view.

    I'll need more detailed information to help you further.

    Hi, I solved the problem. The tuner works fine. It tracks the frequency from the radio and sets the roller inductor and capacitor to the saved parameters for the memorized band slices.

    Thank you for your help.

    Excellent. Can you share what the fix was?

    I'm sorry for not answering for so long. I had to replace the USB-RS232 interface. Not all of them work properly.
