Adjusting functions on Loksound V4- Aux1 & 2

[Guest eddie reffin]

Hi all

 

I have one of my class 37s fitted with a V4 with Legomanbiffo WD sounds. Currently I have independent tail lights on AUX 1 and 2 (F19 and 20) and they are set to fade (they were originally allocated to the cab lights. 

My question is, what do I have to do to change the fade function and keep them constant? Ideally I would like to move them to F4and F5 but not essential, the main thing is to stop the fade. Is it a case of adjusting a CV and if so which one and what value should it be? 

 

TIA

Do you have a computer connected to your DCC system.  If so, its going to be a LOT easier with the computer.  Either JMRI, or, if you happen to already own a LokProgrammer, ESU's own software. 

 

Fading.   Page 63 of ESU's English language manual for the V4.  

First, set CV31 and CV32 to zero.  (Always check what values of CV31/32 are needed before doing anything around functions or sounds in an ESU V4 decoder). 

Next, the fade is one of numerous "modes" available on each function output.  To remove it, the mode becomes zero.  So, for Aux1 this is CV275   and Aux2 is CV283,  set both to zero to clear the fade. 

 

To move functions around gets very complicated, there are multiple solutions to this change (at a guess several hundred solutions!).  

Pages 50 to 60 of manual.   And either a computer to aid you, or a large piece of paper to keep copious notes.   

You need to determine the mapping line used for FnKey19 and FnKey20,  which are probably lines 25 and 26 (intelligent guesswork on my part, as most sound projects don't change the default mapping lines). 

For each line, read across the table on Page52, noting the Index CV32 value, the CV for Control CV A (contains the FnKey1),  Control CV B (contains FnKey2), control CV F (Contains FnKey's 19 and 20). 

Set the index CV's CV31=16 and CV32=tableValue .

At this point, I'd read back the control CV F for each line and work out if it is showing this as FnKey19 and 20 respectively.   And, then I'd go further over the table to read back the outputs in CV K, and confirm that CV is showing that Aux1 and Aux2 are on that line. 

Knowing we're on the right line, its possible to change add the keys FnKey1 to CV A on Line 25, and FnKey2 to CV B on Line26, and optionally remove the keys 19 and 20 from their respective lines. 

Reset the index CV's CV31 and CV32 back to zero when finished.

Hi Nigel,

 

Thanks for the quick reply. Yes, I have a laptop connected to my Lenz LI-USB which has a CV editor. I'll give the first part a try first and stop the fade. Moving the functions isn't as vital but will sit down after the festivities and have a play. 

 

Cheers

Good luck with doing it manually! A doddle using a Lokprogrammer and a few mouse clicks.....the original auto switching pre set for the cab lights will also require cancelling else tail lights will go off when loco moves and back on again when it stops.....

 

Merry Xmas

I agree that manual is hard work.  

Given that Eddie owns a Lenz computer interface, his cheapest option will be JMRI, which offers a user interface which is very similar to that on the LokProgrammer for moving functions around in a LokSound/LokPilot V4.   So, achieves the same result without spending over £100.
