Using the new 1.1 is fantastic.
The ability to work different bands and different modes as per slice is great.
I am really getting use to working ssb on slice A   monitoring another band and a third or 4th monitoring digital .

However what I am seeing is any slice other than A  .
 IE:  B  or C  or D  selected and active in DM780 cannot read the frequency (CAT) nor provide the DAX audio channel for transmit   . (Dax is selected  and activated both Xmit/rec. )

Yes I have the Dax control panel active . Yes it works perfectly with using slice A  Transmit/Receive )

Selecting B,C,D slices and activating the Transmit (TX) on that slice  produces no frequency or Audio transmit  information.

This is correct.  CAT is a legacy protocol that was designed to only address VFO A and VFO B for legacy type transceivers.  So SmartCAT only maps Slice A to VFO A and Slice B to VFO B.

I would recommend you contact the HRD folks and ask them about interfacing HRD with the SmartSDR TCP/IP (network) protocol so their application is aware of multiple receivers.  We will be happy to work with them in this endeavor.

I guess I'm getting greedy . Now having 4 slices  To me it was logical to allow any one of that  4 , or 8 in the 6700 to be selected  since the TX select  button is out there and the highlight frequency tune is also.
Will be glad to advise HRD of this multiple receive situation . So I'm guessing that Flex will make this  function possible ??? Not asking for multiple transmit just any slice transmit  .

When we built CAT for the FLEX-6700 we discussed if we should try and extend CAT and write new commands to address new slices in our radio.  This would require the software programs that use CAT to go and write all these new commands also.  In the end, a much cleaner option is for the programs to just issue the commands to the SmartSDR API which is very easy to use.  It also eliminates all the virtual serial port stuff that is such a hassle to setup.  So rather than keep trying to mold CAT into something it is not, we opted to publish the API and offer to help software folks write to the API.

The TX button in the DAX control panel is not what it first seems.  If you are using digital programs on multiple slices, you can just press the TX on all of the DAX channels in the control panel.  When you go to transmit, the selection of what slice is transmitting is made in SmartSDR, not in DAX.  

But if you are using multiple computers for doing digital modes, the TX is interlocked across computers -- so you you select TX on computer A for DAX channel 1 and then go click TX on computer B, it sill uncheck TX on the first computer.  This allows you to monitor a single DAX channel on multiple computers and have a single transmit computer.  If you are using a single computer, you can press TX on all channels you are using in the DAX Control Panel and let SmartSDR figure out which slice is the transmit slice.
