I keep looking for any Idiot's guides to help comprehend CAT, DAX & DDUtil while trying to understand how they fit/work/help in the Flex 6x/SmartSDR world. I finally stumbled across a diagram that started unraveling where DDUtil fits into the puzzle, and it also shed some light on the linkage or pairing of Comm ports that keeps surfacing. This diagram appeared near the end of the KI5SS topic: https://community.flexradio.com/flexradio/topics/smartsdr-for-windows-smartsdr-cat-powersdr-flex-rad...
I tagged on to that thread asking for ideas where to be looking, but since the topic was more targeted to PowerSDR and the Flex1500 radio, I now realize I should start a separate thread to seek help on this in relation to SmartSDR and the Flex 6x radio environment. I'll paste my original inquiry here to try to cast a more appropriate/targeted call for help:
============= My posting added to KI5SS thread ==============
Well, I almost blew over this thread because I thought it was only about power SDR in the earlier radios, and since I have a 6000 series using SmartSDR I thought there wasn't anything in it for me. Luckily I followed it further and see that the drawing by KD7YDW helped me a lot with my confusion about DDUtil and CAT.
I've been trying to follow all of the threads in the community just to get better a understanding as I get closer and closer to implementing a remote station. KD7YDW's drawing has been a big help to bring me around to the understanding that DDutil is just a software application that manages Comm ports in between the various additional support utilities that we use. Now I'm beginning to understand the reason for these parings of Comm ports, such as 3 and 13, 7 and 17, etc. I simply did not understand the what or why for DDUtil.
So, before I move on and start to try to figure out the same stuff about DAX functionality, I have a couple questions I hope someone could help me with.
First, even though his drawing is about PowerSDR, I want to verify that the basic functionality shown applies to SmartSDR as well? Are there any notable exceptions? It certainly was a big help in putting several of the pieces together in my mind.
Second, where is the 'idiot's guide' documentation that I have obviously missed explaining what, why and where for CAT & DDUtil. Because I often need a graphical diagram to understand some of these concepts, I will kick myself if there turns out to be a pre-existing drawing like this somewhere for CAT in SmartSDR. If so, I clearly missed it. (Before anyone flames me, yes I have tried to read the flex documentation for CAT. It's still just escapes me. Hence the desire for the idiots guide.) I realize the DDUtil is not a Flex product so I'm asking if anyone is aware of such an guide for it. I guess I'm also curious why, if such an important product or utility is needed, that it is not from Flex? Or did I miss something here?
I guess while I'm at it I'll also ask if there is something similar in the form of an idiot's guide for DAX? I try to follow all the dialogs on the DAX subject/problems. I've also tried to read the Flex documentation on the subject but it goes right over my head. So, since DAX seems to be such a complex subject, if there is some document & diagram that ties it all together at a high level for DAX too, I sure want to find it.
Thanks for any help or directions any of you can give me. 73
