R8249 loco decoder or R8245 Sapphire deoder

but most people opt for the basic one. If you want excellent motor control

or many features then people tend to look beyond Hornby decoders.

if you search the forum there is some discussion on the pros and cons of the 8245. see also the downloadable leaflet.

it is much more configurable than the 8249 and has a higher current capacity.

some of the extra features are:-
1. programmable

speed curve
2. "fuel" consumable
3. lighting effects
4. automated running (4 "events" definable)

In total there are about 100CVs (yes 100!). The 8249 has more like 10.

If you use decoder pro then I have written a decoder definition to

allow gui-based programming and storage of the CV settings. NB it takes approx 15-30 minutes to read all CVs!

The 8249 is fine for all basic ops. the 8245 seems very powerful (in both senses). It is also physically bigger.

as to your question....

I use a mix of 8245 and 8249. the 8249 is probably more than I need.

Ian,
something worth trying if you get jerks and stutters is to set the back emf cutout to 1.

I had problems with a Class20 running jerkily with and 8249. When I put an 8245 in it the jerking was worse. I thought that I must have fouled the mechanism

(jammed not the other one:-)).

after a bit of research I changed the back-emf cutout and it runs beautifully.

Hi Greg
Thanks for the reply, the 8249 can't change cv2 that is why I tried the tsv decoder

and I must say the L1 now runs extreemly smoothly, I never tried the 8245 as it is quite big and was concerned it would not fit.
Ian.

no but I've spoken to people who sell both etc. The cheaper one sells around 10:1 which makes sense

given it is half the cost.

The Sapphire is quite expensive given it's lack of fine motor control. I moved to another brand to achieve smooth running on an old loco.

Anyone able to tell me what I'd need to do to add sound to my Pendolino set that the kids just bought me. It states DCC Ready but being a complete novice I haven't really got my head around the DCC stuff apart from it operates great and sounds good too. I have only been bitten by the bug since xmas and already buying track from ebay in the hope of building something good..

Scribbler99....welcome to the forum with your 1st post.

.

Your question is completely unrelated to the original thread. The last post prior to yours was in 2011, so it is well out of date by now anyway.

.

You would be much better served if you started your OWN thread in the Hornby DCC forum section with a 'Topic Title' something like "How do I add sound to a Pendolino".

.

Click the great big blue button at the top of the page entiltled "Add New Topic". Then make sure you put a proper title in the title box similar to the one I suggested, and also make sure that the 'Hornby DCC' forum is selected in the pull down menu box.

.

You might want to consider modifying your question as it contradicts itself. There are two lines in it, that seem to be at odds with each other. Either it has got sound or it hasn't.

.

"tell me what I'd need to do to add sound to my Pendolino set"

"apart from it operates great and sounds good too"

Chris is of course perfectly correct about its being best to add a new topic in the DCC forum, but to start answering your question:

 

For a start, DCC Ready means the loco is ready to have a DCC decoder fitted to run on DCC, but currently there is no decoder fitted and it runs on DC only.  So until you fit a decoder, any decoder sound or otherwise, and get a DCC controller, you won't be able to have any sound.

 

To find out more about DCC, start by reading the DCC section on this website, and once you have your head around that, then Google Brian Lambert and go to his excellent website and its DCC sections in particular.

 

Once you've done both of those, come back and start new threads for any particular questions you still have.

The thing to remember here is that Scribbler has a Pendolino, any sound unit will need a fairly specific 'soundscape' if it is to be realistic. The cheaper motion detection sound units tend to come in two basic flavours 'Steam Chuff' and 'Diesel Rumble'. To get a Pendolino 'soundscape' one would probably need to resort to a full blown Loksound type decoder from a specialist sound decoder supplier, this of course would not be a cheap upgrade.

.

More than happy to be proven wrong, as at the time of writing I haven't actually researched what Pendolino 'soundscapes' may be available from the various sound unit suppliers.
