Has anyone used a Hamation Shack Master 8?

I just got one and have not been able to make it work SO2R with my Flex 6400. It does work fine on the radio 1 ports on the 2x8 switch but not the radio 2 port.

    Okay, I figured out a solution myself.

    1.Configure the Shack Master 8 (SM-8) connected by itself (no other switch controller) per the instructions.
    2.Connect a Hamation PB-28 via the Shacklan port (RJ-45) to the SM-8 and connect the Hamation 2x8 antenna switch to the PB-28 green switch connector.
    3.Press and hold the left radio 1 AUTO button (red) for for at least 2 seconds.
    This allows the Radio 1 port to be controlled by the PB-28 manually and Radio 2 port to be controlled by the Shack Master 8 automatically.

    There may be other ways to configure this with other equipment but this works with what is available to me.

    After some more experimentation, I found out the following:
    on the Shack Master 8 "Radio 1" refers to the Radio 1 port on the PB-28 and the antenna relay. "Radio 2" refers to Radio 2 on the PB-28 and antenna relay. So if you want the 2x8 antenna relay to send the antennas to "Radio 1" Automatically select "Radio 1" on the SM-8. If you want to direct the antennas automatically to "Radio 2" select "Radio 2" on the SM-8. Both Radio 1 and 2 on PB-28 must be in the manual mode and both orange LEDs must be off. The PB-28 acts as a **** to the SM-8.
