LGB new to this DCC help?

[craigwrdouglas2]

Oh also is that what the back EMF does ? As I believe 55021 has this back EMF function which it says helps on dirty tracks?

Back EMF is the load compensation system - essentially if you set the speed at 3, then the chip monitors the motor and attempts to keep it going at that speed even if it is going uphill or round twisty track or if the train is heavy. It's very useful for outdoors where the garden has natural gradients.

I assume I just click on his link from your mail.

No, go to the options bar at the top of the page and on the right hand side you will see your name, an envelope, a bell and the search tool. Click on the envelope to open 'direct messages' and then it is like an email. As you start typing the name of the recipient you will get a dropdown list of names and you can click on the one you want. Put in the title then write your text then press send.

is there a way to connect him to this thread to help him see.

Yes, as I have done by putting in his name he will see at his next visit that he has been mentioned and will probably want to know why so will come and take a look.
To see how to put in a member's name see the 'Help required, I give up, please help me' section and there I have put an explanation of 'How to use the @ function' which when used notifies the member that they have been mentioned.

Philip's point about default voltages is important - LGB 55021 has defaults as 5v in line with the parts in the loco.

the Massoth L has default voltages at 18v for these - there are 2 ways to resolve this - 1 lower the voltages through the CVs or 2 replace the 5V parts with their 18V counterparts - i.e. brighter lights or more powerful smoke unit.

M+, M- Motor 'plus' and Motor 'minus'.
T+! T Track 'positive' and Track 'negative'. - But it doesn't matter which way round these two go..

The 55021 decoder (and Massoth equivalent) has pins on the board, so it just plugs-in to the loco. - You would de-solder (or snip-off, close to the board).
Then you 'open' that set of DIP switches. - Dual Inline Package = DIP.

We love our TLA's! - Three Letter Acronyms.

You will probably enjoy the 'buzz' of the Llangollen show, and there is the Llangollen Railway, as well.

I will be there trading (RC Trains) so if you do go, fight your way through the scrum, and say 'hello'.

PhilP.

This great information Phil.
I once took my narrow boat to Llangollen “the black dog” what a laugh.
My whole family were railways my grandfather was a driver at LNER.

If you don’t mind I would love to come and meet you at the show.

I think I will wait on any moves re decoders until we meet.

And yes Acronyms seem to be the bit to learn
But NASA 1968 were the same ..... will tell you a funny story of this when we meet.

Hi Chris and welcome to the funny farm, or forum as we like to call it.
I expect the digital whizzes will help you out but for that connecter plug I had one between a loco & tender which broke off just as yours has. The part is readily available and the fitting is easy, the connecter has teeth which go through the insulation of the wire and make contact with the core - no soldering! I think the wires snap off where they enter the plug due to being constantly flexed, they certainly were on my Nicki & Frank S.

Hi Pugwash I will get the loco back and give it a go. It must be possible... the train dude it’s with isn’t sure may be his age but I fancy giving it a go.

You know what your iPad thought is a really good point. One I hadn’t thought about. But yes without a button you would spend a lot of time looking the screen.
Also given I got a MTS for so little I may as well get going and learn on that for now.
I’m actually really excited to get going as even in analog we got a lot of joy seeing our train potter around the garden. So digital even basic will be a great improvement particularly with carriage lights working better.
So I have a chap who has a decoder 55021 that may be a good start. And although it won’t do sound I can look at that later. It’s £85 not sure if that’s a good price as I couldn’t see any others on line.
Love your screen point that’s made my mind up thanks

£85 for a 55021 - dont do it.

You can get the Massoth equivalent - Massoth Emotion L (8154001) decoder for £62 from Garten Bahn Supplies (Gartenbahn Supplies - Massoth Products) or £75 from P&S Hobbies.

If you get an eMotion L decoder, ask the supplier to lower the light and smoke outputs to 5v for you and to change the Address (from 3) to the number you require (1-22 on the MTS system).

Ok that’s great ….. and to the point of gradients are they best avoided

ah ok well that’s good. Talking of inclines are they best avoided or ok as I have a four inch or 100mm drop from my new tiles to the gravel (pictured below) or I can trestle build the track like in old westerns. Not too bothered as buildings could be lower than the track and a grit ramp up for where the station is to be ?

Also is back EMF that helps if your track is slightly dirty …

Great info Muns …. So the place I buy this will make the alteration prior to sending if requested ? That’s great
Maybe another dumb question does eMotion L have an out put to add sound at a later date or do I park that up for now?
Sounds like a better price definitely
So will ask Dave to put it back together and look at your supply place then find someone a little bit more experienced to put it in.

Wow the Massoth range seems great and very clear.
I will give them a call. Thanks it’s certainly the way to go.
Still not very good on the different power requirements ie : 1.5 v 1.9v etc
I assume it relates to the power your loco needs some being two motor and much bigger.
On DCc the track gives 5v is that right and the decoder allows the right power from this to the motor and cv’s in the loco ?
So spare power left at the track is then used by the other loco or turnout bits you add.

On DCC the track VOLTAGE is between 18-24 volts, which you set on your Central Station.

It is the DCC chip inside the loco that regulates the voltage to the motor, lights and smoke generator....

Ah ok so there is a lot of spare power at the track. So my loco uses 5v ? So when it’s running lights on … there would be 13v spare to use in other places.
