Flex 6600 USB to Elecraft KPA500 RS232

Hello I have a Flex 6600 and also an Elecraft KPA500 so far I had use it manually band switch via RCA PA Key.
I notice the Flex 6600 has a couple of USB ports under the LAN port.
And my KPA500 has no USB but it does has RS232 PC / RS232 XCVR / AUX3 ports.
Can I connect my Flex 6600 from one of those USB to one of the RS232 on the KPA500 to have auto band switching ?
Thank You, 73.

Juan,
Yes. You can connect the RS232 (XCVR) - 9 pin serial on the KPA-500 to the Flex 6600 M USB ports for band and frequency info. Be careful to use the correct cable.
On the KPA-500 do a long press “Menu” button, scroll to “RS232 X” set to 38400 to match Flex 6600 USB Advanced setting. Go to “RADIO” menu and set to SERIAL. Go to SER POL menu and set polling to ON.
Good luck!2 -
Juan - I am running an rca cable fm 6600 tx1 jack to kat500 (top jack), then rca cable fm kpa 500 pa jack to ptt relay jack on kat 500. I find no need to do manual band switching with this setup.

I just let mine switch by itself. As soon as you transmit the KPA500 switches instantly. I have never found a need to use a RS232 connection.

As was indicated, I use the USB/RS232 solution on the back of the radio. It works seamlessly.
The instructions are in the USB document as outlined above. Very easy to do.
