Ok, AIUI it's a) a data-packet format; and b) a (short) list of addresses where the decoder searches for information (such as speed range.) The decoder itself uses software (firmware) to decode the data, etc. So the standard is a protocol, technically speaking. If I understand the term correctly. And how likely is that?) :-))
I think it used to be all the HP range of calculators used RPN. But these days, most of them are now algebraic with one or two using RPN. I've got one of the latest RPN ones - the HP33s - and it can be switched to algebraic operation if required. I started with an HP25 way back in the mid 70s.
IIRC, one of Clive Sinclair's early scientific calculators used RPN as well.

I don't know what the episode numbers are, but last Sunday's was a bit weak. Not an alien or supernatural event in sight :-(
I'll never trust the fairies at the bottom of the garden again though now!
As can any command station since programming of CVs, in service mode at least, has nothing to do with the address.
To program in ops mode (on the main) you do need to know the address and that address has to be supported by the command station.

Astrac?
Thanks. Ah but thats was an earlier quibble, we're not sure if thats a feature of the system or if its cos the decoders werent set for 2 digit addresses. So far no ones has answered that question so the jury is still out.

If it was from IBM it would be an architecture, but we play trains so can accept protocol (and many other things).
This may be where the elite really scores, plug into computer, write bit of software to provide a user interface and there we are. Really cost effective at the price and can fall back on system on its own when wanted.
Of course this depends on how programming goes !

So why aren't the marketing wizz-kids at Margate explaining fully and clearly all about this system they've put together?
John.
You expect Marketing to understand the technology???? John me boy, you must have had a tot too many of the good stuff. :-)

No I didn't Wolf, and that's precisely why there is so much dis-information going around.
I hope 'dis-information' is a word and explains my meaning; I'm certain there is no deliberate mis-information.
John.
It is a word over here, and it means "information designed to mislead". Sometimes that includes lying. It's also used to refer to propaganda put out by Them, as compared Us, who never deliberately mislead anybody. Or so we say.
"Misinformation" does the job you want, I think.
That's the one!

I didn't mean you but other posters in this particular thread not grasping how it all works not that I know the nitty grit details of timings and packet structures etc.
I'm working towards that! I really need to lay some track first.

All that's really required is the understanding of how the DCC 'black boxes' go together, and enough money to buy sufficient of them, oh, and the ability to fit them or get them fitted, and the ability and knowledge to set them up, and ...
Knowing how the black boxes actually work doesn't add to the system... unless you're linking them to a PC or ...
Regards, Greg.P.
Yes but how can we look good if the ill informed dont contribute ?
Simon
Of course it can, the manufacturer will give enough details so they can sell as many boxes as possible with the minimum cost. That means they may find it easier to ignore certain things that can be done to keep things simple. Of course some less ethical suppliers may try to sell you an overspecified system.
One useful tip for the set up/ install is do have a look at the instructions.
