your train slows down and starts up smoothly. Be sure to pick a braking
rate value that’s high enough to bring the train to a smooth stop but not
so large that it over runs the length of the braking section and starts up
again! See Step 3, ‘Configuring the Throttle’, for more information.
3. Disable Analog Mode. This prevents Tsunami from taking off at full speed
when it encounters DC power. Analog mode can be disabled two ways.
Program CV 12 (Alternate Power Mode) to 0 or select a proper value for
CV 29 where Analog Mode is off. See Step 2 and Table A for selecting
the proper value for CV 29.
Now, whenever Tsunami encounters a DC powered section of track it will
slow to a stop and wait. Lighting and sound functions will remain on as they
where prior to entering the braking section. When DCC power is restored, the
decoder will accelerate back to its current throttle setting.
Automatic Sound Functions
Tsunami provides the ability to generate several sound functions
automatically. This is especially useful when your controller lacks a sufficient
number of function keys to control all of Tsunami’s sound effects or when
using Tsunami on a (DC powered) where there are no function controls at all!
There are six CVs associated with the Automatic Sound Functions:
CV 193, Automatic Bell On Set Point
CV 194, Automatic Bell Off Set Point
CV 195, Grade Crossing Whistle Sensitivity
CV 196. Brake Squeal Sensitivity
CV 197, Analog Mode Automatic Sound Configuration
CV 198, Digital Mode Automatic Sound Configuration
Automatic Sound Configuration Register
CV 197 selects which automatic sound functions are enabled when the
decoder is operating in analog or DC mode. CV 198 similarly configures the
automated sound functions for DCC operation.
There are five automated sound functions available:
Automatic Whistle Signals - Whenever the locomotive is stopped or started,
Tsunami will produce the correct whistle signal appropriate for the direction of
travel:
One short toot = Stop
Two Medium Toots = Forward
Three Short Toots = Reverse
Automatic Grade Crossing Signal - When enabled, Tsunami will play a grade
crossing signal (two long whistle blasts followed by a short and another long)
triggered by a sudden upward spike in the throttle.
