New to DCC - First hitch - help anyone?

Me too :-( Only a few references to the 2mm email enquiry address on our website, and I get loads of spam. The other not-publicised email addresses stay clean.

The email goes through my ISP's email filter (98% effective), then mailwasher (usually gets the 2%), then Eudora set to only fetch 3k of message without user intervention (to avoid me making mistakes).

So far, its keeping me clean.

Please enlighten me as to which CV selects between 14 and 28/128 speed steps in a decoder.

I think you are confused with bit 1 of CV29. This controls whether bit

4 of a speed/direction packet is directional lighting control or an extra speed bit. i.e., the selection by CV is between 14 and 28 speed steps, not 14 and 28/128. If the decoder is set for 14 step and the command station sends packets for 28 step then you get strange effects with the directional lighting.

Decoders either support or don't support 128 speed steps, it's not enabled by CV. The packets sent by the command station (advanced operations packets) are completely different to 14 or 28 step.

Which idiot decided to call it 128 step, anyway? To be consistent with the naming of 14 and 28 step it's actually 126 step mode, the other two being stop and emergency stop.

regulations on

The act of removing the suppression compponents yourself is *not* an offence under the EMC regulations. The regulations make no reference as to whether telling someone to remove suppression components is an offence, I suspect not unless blackmail or some other form of coercion were involved. In general, if you tell someone to commit an offence, and they go and do it, are you liable?

Causing interference or selling things which cause interference *is* an offence. Fitting decoders in the course of a business and removing the suppression components could be committing an offence if the result causes interference.

Can you point to hard evidence of this? I'm interested as I don't believe it to be the case. I believe most decoder designs rely on the motor being isolated from the track by the decoder circuitry (not specific suppression circuits). There may still be some emission from the motor, but less than the DC case where there's a direct connection between the motor and the track which acts as a large aerial for transmitting interference.

I have no idea, but my comments explained what I had effectively been told by the manufacturer.

CV29 selects between 14 and 28/128 speed steps. It also selects several other things as well - Direction of normal travel, Analogue conversion, Speed table and 2-digit or 4-digit addressing.

A good manual will explain in simple terms how CV29 works and how to set it to do what you want. At least the EasyDCC Manual does.

Once you've decided what you want, CV29 is easily set to that value - at least it is with EasyDCC.

With the Lenz Set100, you can use the Programming on Main (PoM) function to set each bit of CV29 individually without having to work out a value for the whole CV29.

several

conversion,

I'm probably being a little pedantic, but CV29 does *not* select between 14 and 28/128 speed steps.

As I said in my previous mail, bit 1 of CV29 has some bearing on speed step mode but determines whether the decoder expects 14 or 28 speed steps in basic speed direction packets. It has nothing to do with 128 speed step packets which are a completely different format and can be neither enabled nor disable by any standard CV. The decoder will respond to 128 speed step packets regardless of the setting of CV29 bit

With EasyDCC you have the option of setting CV29 bit by bit or as a complete value.

Setting the complete value is faster and easier than bit by bit as the EasyDCC Manual has a table in it to tell you what the value of CV29 should be for the options you want..
