OK. I got a new ALS-600 and got the MFJ Flex specific USB cable plugged it in.
Then the amp shut off. I had configured the USB cable BCD active high.
I removed the USB cable from the USB devices window before I unplugged it.
Now my 6300 will not recognize the USB cable when plugged in.
Nor will my ALS-600 power on despite all my efforts.
Any Ideas of what I should try? Hope I didn't **** my new AMP.

    There have been several posts here recently about these cables being mis-wired.  Do a search.  If you can't power-up the amp with the able disconnected, it will probably need a trip back to Mississippi.

    That would be a bummer. I'm hoping I can some how reset the ALS-600. Power supply is making power Plugging the USB cable into a PC and it's not recognized so I'm thinking it's dead.

    iS IT A ALS 606 OR ALS600? The als600 needs the ar500 between radio and amp with the other two cables going to amp

    Then you need an ARI-500 (AR-eye) between the 6300 and the 600. If you plugged the USB cable directly into the amp you likely fried the cable.

    You need the ARI500 and an rca cable from TX1 to relay.  And you will find out that neither the operate / standby switch on the amp or the ARI500 is functional with that setup.
