Get one of these.  You'll never be sorry you did.

There are reports of decoder with Keep-Alives programming problems using a BLI-1020 Address Changer.  Not aware of a workaround.

No disrespect to you Hunt. You're usually spot on. But a locomotive will have a hard time pulling itself up a 25% grade let alone anything else.

. . .

jward,

You having trouble remembering who wrote what and/or misreading what I wrote.

I used 25% in the example just to keep the math simple

"Example, if a 16 oz. locomotive will climb a 25% grade --  multiply 16oz. x 0.25=4oz. drawbar pull on level track."

Drawbar pull

One way to calculate  a locomotive drawbar pull.

Multiply the engine weight, in ounces, by the maximum grade which it will climb, expressed as a decimal.

Example, if a 16 oz. locomotive will climb a 25% grade --  multiply 16oz. x 0.25=4oz. drawbar pull on level track.

One thing is wrong with that equation, because it's old.  It says model railroad cars won't roll down a 2% grade.  

. . .

Trainman203,  NO it does not say a railroad cars won't roll down a 2% grade.

A digital fish scale that reads in ounces should show how much pull a loco has before wheel slip. A more basic rule is pulling power is equal to 25% of the loco's weight. The kicker being, how much do the cars weigh and how free rolling are they that it will be pulling?

If you want to go crazy with the math involved, this is from an old MR comment:

Caveats
If you believe you are mathematically challenged... consider stop reading now.
Make notes... I will delete this post in a few days.
Following uses information based on testing by others and my own testing. Your results may vary depending on the controlling factors of your test environment.
1 inch of elevation to flat run of 100 inches of track = 1.0% (0.01) grade.

Rolling Resistance
Rolling resistance for real railroads is about 0.2%, for model railroads it is more like 2.0% i.e. a model railroad car will roll down a 2% grade on its own. This factor must be taken into consideration when calculating tonnage ratings.
Curve Resistance
Another factor is curve resistance, which is .04% per degree of curve for the real railroads and about the same for model RRs. The big difference is model RR curves are much sharper and this resistance is a very big factor. It is equivalent to around a 30%/R where R = curve radius in inches. An 18-inch radius curve will produce about 1.7% additional resistance. Most mountain model RRs are all curves, so compensating for them usually isn't worth the time, but if you have to cheat on the ruling grade, do it on tangent track.
Locomotive Traction
An all-metal wheel model locomotive will have about a 20% adhesion factor just like the real ones. This means 20% of the locomotive weight can be turned into pulling force (locomotive weight * 20% = estimated Drawbar pull).
So how many 4-ounce cars will a 12-ounce loco pull up a 3% grade with 18" radius curves?
The equation 12 * 0.20 = ((4*N)+12) * (.03 + .02+ .017)
where 0.03 is the grade, 0.02 is the rolling resistance, and 0.017 is the curve resistance (see above)
Answer: N = 6 cars (5.955)
Use actual drawbar pull figure in place of L*E
L*E is a way to estimate drawbar pull
More accurate equation
L*E = (C*N*(G+E+R))+(L*(G+R))
L is Locomotive weight in ozs.
E is Rolling resistance factor of 0.02
C is Car weight in ozs..
N is Number of cars
G is % track grade
R is curve resistance determined by 0.3/r where r is curve radius in inches
12*0.20=(4*N*(0.03+0.02+0.017)) +(12*(0.03+0.017))
N= 7 cars (6.851)

Since pictures are not hosted on this site, pictures need to be hosted on a separate site and often they then have an expiration date.  Best bet is to PM the circuit poster and he can send it to you in an email, or repost a new link on the site here.

If it will not work using just NCE Power Cab,  it will not work using JMRI

The usual suspect is wiring.

Using the Power Cab without JMRI in circuit

Start with motor wiring,

Remove locomotive shell. Locate, pull off and reseat one at a time the black plastic clip holding in place each of the two wires connecting the motor to the circuit board. Be sure the bare end of the wire is in good contact with the solder pad on the circuit board and remains in contact during replacement of the clip.

Reset decoder and test before replacing the shell.

Reset the decoder
Resetting the sound decoder CVs to their factory default value is a two-step procedure.

   1)  Program 8 to CV 8
   2)  Cycle power to the decoder by turning power to the track off and back on.

After about six-seconds upon restoring power the headlight will blink 16 times indicating that the CVs were successfully reset. However, if sound or light come on immediately upon restoring power, the decoder did not successfully reset. Repeat the two-step procedure.

Per my tech notes ---- Air compressor sound is one of the sound files  not  loaded in the Sound Value decoder for that locomotive per Bachmann specifications.

An aside,

Notwithstanding what you may read,  the Dynamis Pro Box does not have a PC interface.

The 40 locomotive roster database is in the Dynamis Command Station and is available to each handheld handset.

Short answer – No

The DCS-51 OpsMode SW7 can be set to 'Blast Mode' for programming sound decoders that require more current than a regular decoder. See the DCS-51 instruction manual for the 'how to' information.

Len

The  Digitrax KB33 article is a better source  for how to use Digitrax Zephyr Blast Mode Programming

Caveat - Before using Blast Mode Programming one should read all of KB33 very carefully, slowly and more than once. Many miss several things. An example: Track power must be ON during Blast Mode Programming.

I have not tried Blast Mode Programming with a TCS WOWSound decoder equipped with a Keep-Alive device.

The Bach-man,
Request you have the necessary electronics people take a look at this thread, conduct engineering level testing and comment.

I do not believe using the 1K Ohm resistor is the reason the address was set.  This is an example of anecdotal evidence that likely will become the basis of what is misinformation.

To reliable program the TCS WOWSound decoder factory installed in the ACS-64 using DCS51 -Digitrax Zephyr Xtra requires a SoundTraxx PTB-100 Programming Track Booster or the like.
