Configuring Lighting Outputs

Tsunami2 provides up to six lighting outputs (depending on
the board format). Lighting output control CVs allow you to
enable Hyperlight effects, Grade-Crossing Logic, phase offset,
and LED Compensation Mode for each lighting output,
determine lighting output direction, adjust the flash rate of
flashing Hyperlight effects, and set lighting output brightness
levels.

Enabling Hyperlight Effects and Features

You can use CVs 49-54 to enable Hyperlight lighting effects
and features for the headlight, backup light, and FX3-FX6
lighting outputs. This section details each Hyperlight effect
and feature and shows you how to customize lighting outputs
to fit your operating preferences.

On/Off Output

The on/off lighting effect provides on/off control for
the corresponding function. Use this effect when
the function output is being utilized to drive
external electronics such as a low power relay to
control a smoke generator or a servo motor.

Dimmable On/Off Headlight

The output set to the dimmable headlight will be
reduced to the brightness setting in CV 63 when
you turn on the dimmer function (F7 by default).

Mars Light

The Mars light warning beacon follows the famous
figure-eight sweep pattern and oscillates more
rapidly than the Gyralite.

Pyle-National Gyralite

The Pyle-National Gyralite is similar to the Mars
Light, but oscillates in a circular or elliptical pattern.

Oscillating Headlight

The dual-oscillating headlight generates two
beams that follow each other in a tight, circular
sweep pattern.

Single-Flash Strobes 1 and 2

The xenon single-flash strobe 1 effect flashes once
during each flash rate timing cycle. The xenon
single-flash strobe 2 flashes once during each flash
rate timing cycle, but at a slightly faster rate.

This effect allows you to mimic warning lights found
on many Amtrak locomotives as well as remote control operated (or “RCO”) locomotives.

Double-Flash Strobe

The xenon double-flash strobe effect emits two rapid flashes of light during each flash rate
timing cycle. CV 59 is used to modify the flash rate timing cycle.

Western-Cullen D312 Rotary Beacon

The Western-Cullen D312 Rotary Beacon effect follows a revolving reflector and bulb assembly
flash-pattern.

Prime Stratolite

The Stratolite is made up of four individual lamps arranged in a circular pattern. The Stratolite
flashes in a clockwise direction in a mechanical “stepped” fashion, unlike the smooth motion of
the rotary beacon.

Ditch Lights Type I and II

Ditch lights type I and II flash together by default. When Grade-Crossing Logic is enabled, ditch
light I assumes

a steady “on” state before and after the crossing hold timer countdown.

Conversely, ditch light II will remain off before and after the crossing hold timer countdown. To
configure alternating ditch lights, set one lighting output to ditch light I or II and enable Grade-
Crossing Logic, and then set a second lighting output to the same ditch light and enable Grade-
Crossing Logic and phase offset.

Flashing Rear End Device (FRED)

The FRED effect is a flashing red taillight that indicates the rear of the train.

Engine Exhaust Flicker

This effect produces a random flicker whose intensity increases with locomotive speed. This
effect is best used by placing a red/orange LED in the exhaust stack. As the locomotive
increases speed, it will glow brighter, imitating an increase in sparks and exhaust gases.

Dyno-Light

In a diesel locomotive, the lights will fade on and fade off to simulate the heating and cooling of
the bulb filaments.

Auto-Dim Forward and Reverse

The auto-dim forward effect will automatically dim lighting outputs to the dimmer level in CV 63
when in the forward direction, and the auto-dim reverse effect will automatically dim lighting
outputs to the dimmer level in CV 63 when in the reverse direction.

Brake Light

The brake light effect is dimmed to the brightness setting in CV 63 when active. The brake light
brightness level will be automatically set to 100% when you turn on the independent or train
brake function (F11 by default).

On/Off Brightness 1 and 2

On/Off Brightness effects 1 and 2 allow you to independently adjust the level of up to 2 lighting
outputs. You can accurately recreate low brilliance lighting effects on your model such as class
lights, lit number boards or marker lamps. The on/off brightness 1 and 2 effects will set lighting
outputs to the brightness levels of CVs 61 and 62, respectively.

Emergency Gyralite

The emergency Gyralite follows the same oscillating sweep pattern as the Gyralite, and will
automatically disable all active lighting effects.

Basic Programming

Tsunami2 Diesel User’s Guide

Phase Offset

Add a value of 32 to the value of flashing Hyperlight effects to set the corresponding lighting
output to Phase B from Phase A. Flashing effects set to Phase B will flash opposite of flashing
effects set to Phase A, i.e., Phase A turns off when Phase B turns on, and Phase A turns on
when Phase B turns off.

Grade-Crossing Logic

Grade-Crossing Logic allows you to set up lighting functions, the bell, and airhorn to
automatically simulate encountering grade crossings. Add a value of 64 to enable Grade-
Crossing Logic. Turning on the long airhorn function (F2 by default) or the grade-crossing signal
function (F9 by default) will start the crossing hold timer countdown and allow lighting effects to
assume a flashing state. Shown in Table F, flashing Hyperlight effects will return to an on or off
state after the countdown ends. Practice activating Grade-Crossing Logic as your locomotive
approaches a grade crossing. You can adjust the crossing hold timer countdown from 0 to 15
seconds by entering a value from 0 to 15 into CV 60 (Grade-Crossing Hold Time).

To allow the bell to ring during the crossing hold timer countdown, enable the grade-crossing
bell feature in CV 122 (Bell Select)

. Refer to “Configuring Sound Effects” for more information

about the grade-crossing bell.

Refer to Table F located below for a list of Hyperlight effects commonly configured with Grade
Crossing Logic (including alternating ditch lights) and corresponding CV values. The state of the
effect while the Grade Crossing Logic hold timer is not active is also listed.

LED Compensation Mode

The brightness of an incandescent bulb is determined by voltage, whereas an LED

’s brightness

is determined by current. LED Compensation Mode alters the method of sending current to the
LED to balance the LED and incandescent brightness levels. Add a value of 128 to enable LED
Compensation Mode for the corresponding lighting output.

Note: Enabling LED Compensation Mode will not change the output voltage. Resistors may still
be necessary depending on the board format and drive voltage of the LED.

Adjusting Lighting Output Settings

After configuring Hyperlight effects and features with CVs 49-54, adjust CV 57 (Forward
Direction Enable), CV 58 (Reverse Direction Enable), CV 59 (Hyperlight Flash Rate), CV 61
(Brightness Register 1), CV 62 (Brightness Register 2), CV 63 (Dimmer Level), and CV 64
(Master Brightness Register) to customize lighting output direction, the Hyperlight flash rate, and
brightness levels.

Enable Lighting Output Direction

CV 57 determines the lighting outputs active in the forward
direction, and CV 58 determines lighting outputs active in the
reverse direction. Table G shows values used to enable
lighting outputs for the forward and reverse directions. To
enable lighting outputs for the forward direction, add the
values of your preferred lighting outputs and enter the sum
into CV 57. To enable lighting outputs for the reverse
direction, add the values of your preferred lighting outputs
and enter the sum into CV 58.

The headlight is disabled in the reverse direction and the backup light is disabled for the forward
direction by default, i.e., CV 57 is set to 61 by default and CV 58 is set to 62 by default.

Set the Hyperlight Flash Rate

Adjust the flash rate of flashing Hyperlight effects from the fastest setting to the slowest setting
by entering a value from 0 to 15 into CV 59.

Adjust Brightness Registers 1 and 2

Adjust the brightness level of lighting outputs set to the on/off brightness 1 effect from 0% to
100% by entering a value from 0 to 255 into CV 61. Adjust the brightness level of lighting
outputs set to the on/off brightness 2 effect from 0% to 100% by entering a value from 0 to 255
into CV 62.

Adjust the Dimmer Level

Adjust the brightness level of the dimmer function (F7 by default) from 0% to 100% by entering
a value from 0 to 255 into CV 63. The dimmer level is set to 60% brightness by default.

Adjust the Master Brightness Level

Adjust the brightness level of all lighting outputs from 0% to 100% by entering a value from 0 to
255 into CV 64. CV 64 adjusts the brightness levels of lighting outputs set to on/off brightness 1
or on/off brightness 2 from the brightness levels of CV 61 and CV 62, respectively. This does
not eliminate the need for resistors. Due to the nature of certain lighting effects, values below
100 may diminish its overall effectiveness.
