How to make amp follow active slice

I use FRStack and DDUtil to control my Tokyo Hy-Power amp in Kenwood mode.  Using one slice on my 6300 everything works fine.  Just tried using two slices and the amp does not follow active TX slice changes.  

DDUtil is configured for RCP1 CAT Port on COM7 but only follows Slice A regardless of which slice is TX and Active.  I can't find other settings to make it track the TX Active slice ... there must be some way to do this.

I can't speak to DDUtil, but with my 6700 connected directly via USB and an FTDI serial cable to the THP amp, the amp follows the TX slice automatically with no problems. My suggestion is to take advantage of the Flex direct USB support and connect the amp directly to the Flex. It is simple and reliable, which is exactly what one wants for an amp band select connection. -Mark KC3DRE

My THP is the HL1.5KFX and the flex 6500.
I have a null modem adapter on the amp RS232 and the ftdi attached to to the null modem.  The direct connect to the radio USB works seamlessly.  You do need to be running SSDR version 1.19.16.  This is much easier to deal with than DDUtil.

Got it!  Rather than waiting for some responses about using DDUtil I went ahead and upgraded to 1.10.16 and connected to the USB port - works fine!  

I still have to keep DDUtil because I share all of the other equipment (tuner, coax switch) with an Icom radio and DDUtil does the protocol translation for them, but nice to have the amp switch on TX Active slice changes now.
