If you are using the front console on the radio, then shut down the radio by pressing and releasing the power button.
If the radio is shut down, then the connection to CAT and DAX is in a disconnected state and will reconnect to the radio once it is powered back up. You can choose to either keep DAX and CAT running on your desktop or not. It really doesn't matter. The will connect to the radio once it is powered up and the radio is communicating over the network.
And both DAX and CAT will close cleanly when you shut down the PC.
Thanks Tim but what if I shut down the radio and it disconnects then the next time when I start the 6400M I do it in standalone mode without the computer on, will it come up directly into a panadapter and receiver slice on the radio screen?
The reason I'm asking is I have now documented 4 startup procedures based on whether I am running standalone, standalone with hdmi monitor cloning flex display, standalone with Dax and Cat connected from the computer and not the smartsdr for windows GUI, and the last one smartsdr for windows running the GUI with DAX and CAT controlling the 6400M over the LAN (no internet).
Maybe I am making it too complicated but I am so trying not to mess up my setups and the way I operate and just trying to totally understand it all.
The separate Global profiles for standalone and smartsdr for windows have really made it easy to go from stand alone to computer controlled and back again and still maintain the look/feel of each platform being able to restore settings for each just by loading a Global profile once the startup had completed.
I know I should not be so picky but I like to keep organized and when I do stuff I like to understand why I'm doing it and what I am causing to happen and not do it just cause someone says do it this way.
Thanks for your patience :-)
