Im using a LokPilot XL4 (without a lokprogrammer or software). I am struggling to make sense of the instructions from ESU on function mapping tables and how the conditions block etc work together. I have no problem programming the CV's one by one for the limited uses Im using this chip for, but haven't proceeded much further than these tables.

I know its cumbersome, but at this moment after finishing wiring im getting into mapping servo parameters, and all the brightness and output functions of the decoder lights and smoke units. Any help would be lovely. Im missing I think a key piece in how the CV mapping works.

ESU isn't open for about another week to answer questions so Im trying to put together a missing piece to make sense of assigning the function outputs to buttons. Ive managed to setup functions 1+2 and changed brightnesses and pulses and such, just nothing further.


Cheers!

All I can recommend is that you study the manual and the examples provided until it "clicks". One key to recognize is that each CV from 257 through 511 is used to read or write multiple program settings. That is why CVs 257 through 511 repeat in the first screen shot you've attached which is the Function Mapping Table. The meaning of the setting you read or write depends on the value you program into the "index CVs" which are CVs 31 and 32.

The decoder can recognize up to 32 different combinations of input configurations that will result in some combination of real output, logical output, and/or virtual function. These are the "32 mapping lines" to which the ESU manual refers. The decoder steps through the 32 mapping lines "...several 100 times per second." to check if the input block conditions are met. The decoder will perform the output functions in the line if the input block conditions are true. The decoder then steps to and checks the input conditions in the next mapping line in the table. Note that not all mapping lines need to be programmed. If a particular line's input block CVs all contain zeros, the input condition is never met and the decoder goes on to check the next line in the table. The bullet points on page 51 of the manual explain this.

Hi - I'm an LGB Dealer and Authorized Service Center and also install DCC Sound Decoders into LGB locomotives for customers: ESU; Massoth; Soundtraxx; LGB; Marklin; Phoenix; Piko. The ESU decoders are very complex and a challenge to configure so it's best to use a ESU LokProgrammer to do so. The mapping process is very easy then and you can assign an AUX to the specific F Key you want to use for the device, including assignment to the F0 Headlight and F0 Taillight function. There may be a way to use multiple CVs to program a device but some things like installing a Massoth Pulsed Smoke Unit onto the ESU LokSound 5XL sound decoders I use would be impossible without using the LokProgrammer. I sell them here in the States for $145.
