How do I set CV121 to 64? anyone know? It sets the horn to maximum loud.
Could you provide a few more details? What type of system (Digitrax/NCE/Prodigy etc.), what type (brand + model#) of decoder…
Are you sure that the values don’t run from 0 to 63? It might be a six bit binary number.
Have fun
Step 1 - Re-acquaint yourself with the procedures for programming CV’s in your DCC system’s manual. Should be no more than about five steps.
Step 2 - Re-acquaint yourself with the range of values programmable into the CV in question for the decoder you own.
Step 3 - Following the first manual’s instructions, programme the value to fall within the range stipulated in the second manual.
(This is not meant to be a sarcastic reply, but is precisely the method to use in all cases. The only fly in the ointment might be that your decoder doesn’t like the way your DCC system talks to it, so you may need a programming booster and/or a specific programming track. That is why the others would like more information so that they can say, "That particular set-up needs A,B, and C).
I hope you get it working quickly…these barriers sometimes get in the way of real fun. Been there. [:I]

Doug,
On units like the BLIs, the sound adjustment can also be done manually by prying up the water hatch on the back end of the tender by rotating the know CW or CCW. Probably easier and faster than going through the menus on the throttle.

Its a Lok Sound decoder in a N Kato Mikado. I have a Bachmann DCC (probably outa luck, but could I do it on some other system then run it on mine?) The decoder sounds great btw and I AM IMPRESSED! Just wish the horn was louder.
If you mean the EZ-Command, there is currently no way to programme CV’s with that system. I think you can change addresses, but you can’t alter sound levels, set CV’s 2-4 for start voltage, acceleration, and momentum respectively. For me, that was the single biggest show stopper about the system.
Out of luck with the Bachmann system, you can’t program anything other than the address with that system. You will need to take it to a friend or hobby shop that has other DCC systems and program on one of them.

Ok the hobby shop has a Digitrax. Anyone tell me how to do it so I know what Im doing when I take it in?
Binary is 8 bits long:
00000000 = 0
11111111 = 255
Now the first bit is 128 therefore
10000000 = 128
The second bit is 64
01000000 = 64
if 11000000 = 192 by adding 128+64.
Then the third bit is 32.
00100000 = 32
if 11100000 = 128+64+32 = 224
the rest of the numbers down:
16, 8, 4, 2, 1
Thus the total in bits added 11111111 = 255
Of course you can have a 6 bit number but because you need to have two zeros somewhere you are going to have a group of possible 6 bit NUMBERS.
Time to upgrade to a more advanced system.
Well the manual said to set CV121 to 64 so that is what I want to do. I also want to check the current value of CV121 first.
Step 1 - place loco on track and power up the Digitrax.
Step 2 - acquire the loco by dialing its current address on the appropriate number pad or dial.
Step 3 - Enter programming in Ops Mode. Dial in the CV(s) you wish to programme and then assign the value you desire. Press enter. Exit programming.
Step 4 - Remove the loco to your layout.
I gather that you’re trying to make the horn sound considerably louder than the prime mover (engine) sound. I just did this last night.
Since the Lok-Sound decoder, as shipped, comes with the horn set to full volume (CV121 set to 64), you need to turn down the volume on the “auxiliary sounds”. I ended up programming CV123 to around 35 or so to turn down the prime mover sound to get the difference I wanted. I turned the bell (CV122) down to about 45, as well.
I found it easiest to do this in Ops mode programming, so that I could hear the results immediately. Hopefully the hobby shop’s DCC system is set up so that you can use it hands-on, or at the very least it’s where you can be there to decide whether a specific setting is sastisfactory to you.
If this is a loksound unit like my Reading T1 Unit, turn down all sounds to between 30-45 (Especially the Aux sound) and beef the horn.
That one tidbit saved me from having to reprogram the engine despite the incorrect horn.
Keep writing each CV and the value you program into the engine and why into a small notebook. That way you understand how your engine is configured.
The horns on the Loksound decoders is always too soft (a side effect of not using a capacitor). You are out of luck, I am afraid.
