Don't know the innards of Marks' loco, but I do recall that on some of my Mallets there was a bank of 4 DIP switches relating to sound. (They were under the steam dome) Switch 1 determined if digital or analog mode was in use, so if set incorrectly this may inhibit sounds now the loco is using DCC. Im afraid it's too hot for me to get "Mr Brown" out at the moment but once the weather cools down I'll do some testing to see if/how the whistle works.

Best wishes
Phil

Another stupid suggestion, have you got the 6 way cable in correctly as this powers the lights & sound.

Did you enable serial commands, Jon?
Doh doh doh. What CV is that Phil, not the dreaded CV 29? If so what value please? Also looking at the CV list that the Chips were at it looks like CV51 for Lighting should be 0 rather than the 1 it is at the moment.

CV 49 bit '1' - so decimal value of '1'

May need to set bit '3' (decimal 8) as well


Default value for CV 49 is 2


CV 51 would need to be '0' for operation with the 'light key'..
So by default F1 key would turn the front light on/off.
Set to '0' will be by light key ONLY.
Set to '128' will be forward only, controlled by light key.
CV 52 '64' for on in reverse.
128 for CV 51 and 64 for CV 52 are the defaults..

Function output 1 would normally be used for controlling smoke, so CV 54 would be set for '7' quite often. - F7 to control smoke.

Phil, according to the LGB documentation for the 55021 chip, CV49 controls the voltage to the lights and can be between 1 and 32 (the documentation lists 3 values - 32 for locos with decoder interface, 5 for 5V lights and 26 for 19V lights). Also, doc states CV54 is used to control Hand-off function/Back EMF with values between 0 and 3.

So I guess these CVs (49 and 54) can be used for alternative purposes? Is there any documentation on this other than the LGB manual? Would be handy to know.

Cheers
Phil

Thanks both Phil’s. May need to get Mark back to me to play around a little with the CV Values offered. That by the looks of things may be a solution for Lights, any clues about the Horn?
