Enable Quiet Mode

You can enable quiet mode and set the quiet mode time-out period with CV 113 (Quiet Mode
Time-Out Period). When CV 113 is set to a non-zero value, all sound effects will automatically
turn off after the time-out period elapses when the throttle is set to zero and all functions are off.
Entering values from 0 to 255 into CV 113 will set the time-out period from 1 seconds to 255
seconds. Use the equation below to calculate the quiet mode time-out period:

Time-Out Period = CV 113 × 1 sec.

Not included in software releases prior to version 1.2

The steam generator effect is included with all software revisions but the auxiliary HEP generator effect

is not included in software releases prior to version 1.2. CV 144 default values vary by software release.

Configuring Automatic Sounds

With corresponding automatic sound CVs, you can
configure auto-effects for DCC and analog mode
operation. Auto-sound CVs can help compensate for
lack of function control in analog mode. This is most
useful in DCC mode if you have limited function control.
You can enable automatic effects if you’re unable to
activate them with function keys.

Enabling Automatic Sound Effects

CV 197 (Analog Mode Auto-Sound Enable) is used for
enabling automatic sound for analog mode, and CV 198
(DCC Mode Auto-Sound Enable) is used for enabling automatic sound for DCC mode. The CV
values and sound effects for both registers are identical, e.g., the value for enabling the auto-
bell in analog mode is the same as the auto-bell value for DCC.

Table J shows values for CVs 197 and 198 used to enable
automatic effects. For each auto-sound effect you want to
enable, add the CV values together and program the sum
into CV 197 for analog mode, or into CV 198 for DCC mode.

Enable the Auto-Bell

In addition to CVs 197 and 198, you will need to set CVs 193 (Auto-Bell On Set Point) and 194
(Auto-Bell On Time) to configure the auto-bell sound effect. CV 193 is used to determine the
speed step at which the bell sound effect will be automatically turned on and CV 194 (Auto-Bell
On Time) is used to adjust the duration in seconds that elapses before the bell sound effect will
be automatically turned off. CV 193 may be programmed with values from 1 to 127 to set the
auto-bell speed step from 1 to 127, i.e., each value corresponds to a speed step (1 = speed-
step 1; 2 = speed-step 2; 108 = speed-step 108, etc.). Then program CV 194 to determine when
the bell will stop ringing. Program a value from 1 to 255 into CV 194 to set the duration from 1 to
255 seconds.

Enable the Auto-Brake

You can adjust the auto-brake sensitivity with CV 196 (Brake Sensitivity). In DCC mode, the
decoder interprets this as the rate of throttle decrease. In analog mode, the decoder interprets it
as the rate of voltage decrease. Value

s from 1 to 255 determine the brake sound effect’s

sensitivity. A value of 1 will activate the brake in response to decreases of 0.10 speed
steps/second. A value of 255 will activate the brake in response to decreases of 25.5 speed
steps/second:

CV Value = Speed Steps/Second ÷ 10

We suggest using trial and error when determining the auto-brake sensitivity. In other words,
program CV 196 with higher and lower values and then increase and decrease the throttle
setting until the auto-brake is activated according to your preferences. A value of 0 will trigger
the brakes whenever the locomotive is decelerating.

Note: The best results when using the Auto-Brake feature will occur with some momentum
programed in CV 3 Baseline Acceleration Rate and CV 4 Baseline Deceleration Rate

Modifying Automatic Sound Effects

Sound control CVs additionally allow you to modify automatic sound effects, such as the coach
door slams that occur after the conductor’s “all aboard!” announcement, the release rate of the
poppet valve, the clickety-clack rate, and the various Fireman Ed tasks that occur when the
locomotive is stopped.

Adjust the Coach Door Count

Enter a value from 0 to 15 into CV 195 (Coach Door Count)
to adjust the random number of coach door slams that occur
with the all aboard/coach doors function. Turn on the all
aboard/coach doors function while the locomotive is
stopped to activate the conductor’s “all aboard!”
announcement, followed by the random number of coach
doors slams determined by the value of CV 195.

Adjust the Poppet Valve Release Rate

Enter a value from 1 to 255 into CV 200 (Poppet
Valve Release Rate) to adjust the frequency of
each “pop!” of the poppet valve from the fastest
rate to the slowest rate. The poppet valve releases
more frequently in humid environments and less
frequently in arid environments. CV 200 is set to a
value of 25 by default.

Customize the Clickety-Clack

Follow the steps below to adjust clickety-clack CVs:

1. Ensure CV 31 (CV Index 1) is set to a value of 16.

2. Enter a value of 3 into CV 32 (CV Index 2) to select Indexed CV Page 3 as the active

indexed CV page, and enable access to clickety-clack CVs.

3. Refer to the following information when accessing CV 3.257 and CV 3.258 from your

command station to customize the clickety-clack sound effect.

You can set the number of axles per truck and
number of trucks per car with CV 3.257 (Clickety-
Clack Rate) to adjust the clickety-clack rate
according to the specifics of your model. This
allows you customize the clickety-clack sound
effect to simulate various prototypes.

For example, a bobber caboose has one truck with two axles, whereas some passenger cars
have two trucks with three axles. To simulate a bobber caboose, enter a value of 1 into CV
3.257. For a passenger car, enter a value of 6 into CV 3.257.

CV 3.258 (Clickety-Clack Sound Scalar) allows
you to fine-tune the frequency of clickety-clack and
flat spots sound effects by setting the proportion
between speed step and scale speed. Scale speed
is calculated in feet per second (ft./s). Higher
values allow faster scale speeds and increase the
clickety-clack frequency, and lower values allow

CV 195: Coach Door Count

0 = 0 door slams
1 = 1 door slam

5 = 5 door slams (default)

128 = 1ft/s (default)

slower scale speeds and reduce the clickety-clack frequency.
Enter a value from 1 to 255 into CV 3.258 to adjust the scale speed from 0.01ft/s to 2ft/s. A
value of 0 will disable the clickety-clack sound effects. You can also use the equation below to
calculate scale speed:

Scale Speed (ft./s) = (Speed Step × CV 3.258) ÷ 100

Adjust Fireman Ed Event Probability

Fireman Ed keeps busy when the
locomotive is stopped by performing tasks,
such as refueling the engine, tightening
various nuts and bolts with his wrench,
squirting his pneumatic oiler, turning on the
air conditioner, and occasionally using the
bathroom (he always remembers to flush).
A new fireman Ed task occurs every 10-30
seconds after the locomotive has been
stopped for two minutes and the general
service function (F18 by default) is turned
off.

You can use CVs 201-208 (Fireman Ed Probability CVs) to adjust the frequency of each
Fireman Ed task scheduled to occur while the locomotive is stopped. Entering values from 0 to
255 into CVs 201-208 will adjust the probability for the associated tasks from 0% to 100%. Refer
to Table H to view each event probability CV and corresponding default values.

Example: Adjusting Fireman Ed Event Probability

Every 10-30 seconds, Fireman Ed might open and close the cab door, refuel the engine, tighten
nuts and bolts with his wrench, use his pneumatic oiler, flush the toilet, or turn on the AC. Follow
the steps below to configure Fireman Ed probability CVs:

1. To allow Fireman Ed to enter and exit the cab when the locomotive is stopped, enter a

value of 100 into CV 201.

2. You can simulate refueling the engine at the appropriate times with the fuel loading

function (F17 by default). To prevent Fireman Ed from disrupting fueling schedules,
enter a value of 0 into CV 202 to disable the automatic fuel loading sound effect
(default).

3. To allow Fireman Ed to tighten nuts and bolts on the locomotive periodically, enter a

value of 64 into CV 203.

4. To allow Fireman Ed to use his pneumatic oiler at the same rate as his wrench, enter a

value of 64 into CV 204.

5. You can turn on the radio to hear cab chatter with the cab chatter function (F22 by

default). To disable the automatic Fireman Ed cab chatter sound effect, enter a value of
0 into CV 205.

6. To allow Fireman Ed to use the bathroom after a grueling 12-hour shift, enter a value of

25 into CV 206.

7. To allow the air conditioner to turn on often enough to keep the crew from overheating,

enter a value of 150 into CV 207.

8. To allow relay clicks to occur regularly, enter a value of 100 into CV 208.
