You cannot alter the output rail volts of a Prodigy DCC system. It is preset with the Express at 13.8 volts at 2.0 Amp and the Advance2 at 14.5v at 3.5Amp

Top speed is CV5. Check the decoders manual for the range of values a particular decoder make may use. Frequently 0 to 63 or 0 to 255
Once CV5 is set, set CV6 to between 1/3 and half of the value of that in CV5. However, I don't believe Hornby TTS decoder have CV5 and CV6 available!

I have a Gaugemaster Prodigy Express and no other means to control a loco. Recently, bought a new Bachmann DCC Ready Warship. I intend to put a TTS decoder in but in the meantime, can I test run the Warship without a DCC chip via the Express to make sure it runs ok? Im not talking running it for 1 ...

<Snip> So what I want to do is use my Electrofrog points that have all been fitted with insulated joiners at the frog into a DC layout, the problem is I am having trouble trying to figure out what rail to fit a switch to, I expect I will need to build a switch board which is no problem but I am con...

Hi Before you start you will need to check on which bus wire feeds which rail. Then once that is determined carry on wiring with the same insulation colours for the rails. So for example if you previously wired Red insulation colour to the Right hand rail you need to ensure your new wiring is Red dr...

I have two Bachmann 20s than run fine with Bachman decoders a heljan 33 with a Bachmann decoder that runs fine and a Dapol 122 with a hattons decoder that runs fine. I have check the track and it’s clean have also used the Locos on a rolling road which creates the same issue. What setting should CV...

5Amp rating is more than enough for most uses.
Unless you're a DCC (Digital) user with a Booster that outputs more than 5Amp.

Me too. 6 pin on a set of leads. That's new! Doesn't seem like anything special? I love the Hornby web sites description of this new decoder.... Hornby is a household name and is famous as the UK's brand leader in the model railway hobby with its high quality 00 gauge (1:76) models and accessories. ...

As stated on the other forum... Of course they won't move as individual locos, you have assignment a Consist address to them, so they both move together. You need to Dissolve or Clear the consist. See page 30 or page 32 of the PowerCab manual depending on what type of Consist you have set up for the...

Has anybody used servos to motorise the Bachman’s cranky thinking with couple of servos I can have rotation Crain an raising an lowering hook. Has anybody done it and any issues I might experience. I have couple of the servo test wheels for control ether than programming like a mega point controlle...

Hi Are they Hornby? AFAIK Hornby only sell 4, 8 & 21 pin fitting decoders. Uncontrolled DCC runaways are normally solved by... A) Turning off DC operation via CV29 by setting its value to 4 less than read i.e. read CV29 as 6 so set it to 2 or 38 set to 34, if you can't read CVs values then just ...

The relays you're mentioning are twin coil latching. Therefore they are suitable. If you wish to ensure the added voltage from the CDU doesn't cause their coils a problem then add a 1K0 1watt resistor to each input. See here... link to item However, I use 12 volt Latching relays wired directly to th...

Hi First check the wiring.... Return wire must be on Seep terminal C. Operation left and right wires from the switch or lever to A and B terminals. Visually check there are no solder whiskers or wire stands able to short between two tabs on the Seep If that all proves correct, remove the problem See...

Try moving the PL26 lever over slower?

Hi all I am trying another form of pick up spreader for another container crane and would like to go down the same route as Heljan using an electromagnet. The question is, can I use a DCC decoder function to operate for on/off? I know I’ll need a good bit of power but unsure where to go next? Iain ...
