Zimo MX645

[MarkAllen]

Evening all. I want to hard wire my zimo mx645 decoders from digitrains, so that I have independent control of all the lights individually. I love the new brake function and would like to keep that as is along with horns and other sound functions. I want to be able to select which headlight is on regardless of direction and individual switch tail lights on or off depending on weather it’s attached to a train or not. So using the wires already on the decoder (yellow, white, green and brown) can I then assign these functions to F keys I don’t use regularly such as the reserved F23-26.

I have a lenz lzv100 with lh90 which I’m happy in using to change cv’s individually.

Hope this makes sense and thanks in advance.

You can map the FOs to be forward or reverse or both, and you can map them to any Fn button you want.

You need section 3.17 of the manual which is misleadingly labelled Swiss mapping.

Do not be put off by the word Swiss, this mapping method allows considerable flexibility over which function button drives which physical outputs.

Have a look at this thread which explains the basis of (Swiss) mapping.

Thanks both, I shall have a good read and see what I can achieve.

So I’ve had a good read and as far as I can workout Swiss mapping is also direction dependant, so by mapping various bits you can turn tail lights off when connected to a train but if you then push that train the headlight will come on in the direction the loco travels. Watching videos of 50’s at Waterloo it was sometimes common practise to arrive with a train, uncouple then when tha train departs the loco would reverse with the headlight still on, effectily going the wrong way. I know it may not be by the book but I wish to emulate this. Swiss mapping seems not to be what I’m trying to achieve, or am I missing something.

I’ve managed to disable F0 so now no lights come on regardless but I don’t seem to be able to reassign to F23-26. I’ve used cv 423-328 but nothing. So I’m getting more and more confused.

Any pointers please?

Mark,

 

You can get any function output to operate in either direction, Swiss mapping is exactly what you need. In fact it is not possible to map to the high F keys without SM.

 

Tell me the project and version number you have, and the F key you wish to operate each set of lights and I'll give you the correct CVs to make it happen.

 

Best regards,

Thanks for that Paul. So it’s your latest class 50 active speed lock on zimo mx645r but I’ve wired no 1 cab headlight to the white wire, no 1 cab read red to yellow wire, no 2 cab headlight to green wire and no 2 cab read red to brown wire. I want no 1 headlight on F23, no 1 red F24, no2 headlight F25 and no 2 red F 26 as all these are reserved on your current project. Hope that makes sense.

Mark,

 

Sorry, had to go out.

 

To avoid F key 0 operating any lights:

 

CV33 = 0

CV34 = 0

 

To put the lights on the F keys you require, use Swiss Mapping as follows:

 

CV430 = 23

CV432 = 14

CV434 = 14

 

 

CV436 = 24

CV438 = 15

CV440 = 15

 

 

CV442 = 25

CV444 = 1

CV446 = 1

 

 

CV448 = 26

CV450 = 2

CV452 = 2

 

That should give you what you wish. Compare with the posting I refered to earlier and you should be able to see the logic. (The one anomaly is the numbering os FOf and FOr as 14 and 15 respectively).

 

Best regards,

 

Paul

No worries at all. Fantastic that’s perfect. Had to do a hard reset to undo all my faffing but all well now. Brilliant thank you. And as for your sounds they’re just awesome. Just got to mill the chassis now to fit some EM2 speakers in and it really will be a thundering 50. Four sound projects down sixteen to go.

Thanks again
