Basic Programming
LED Compensation Mode - SoundTraxx Lighting Decoder’s Hyperlight
effects can be used with either incandescent bulbs or LEDs. However,
because of their differences in brightness characteristics, some lighting
effects will appear less life-like when initially set up with an LED. To correct
this, the LED compensation mode should be enabled which will improve the
contrast of the lighting effect by automatically adjusting the function output
level to correct for the different brightness characteristics of an LED.
To set the Hyperlight configuration CVs, proceed as follows:
1. First find the CV value in Table G on the next page for the desired
lighting effect and operating mode.
2. If you wish to enable Rule 17 Mode, add 64 to the table value shown,
otherwise, proceed to Step 3.
3. If you’re using incandescent bulbs, skip to Step 4. If you are using
LEDs, enable the LED Compensation Mode by adding 128 to the sum
computed in Step 2.
4. Program the sum computed in Step 3 into the CV corresponding to the
appropriate function output. Use CV 49 to set the headlight, CV 50 for
the backup light.
Setting the LED Brightness
CVs 55 and 56 set the overall brightness of the lighting outputs. This can be
helpful to decide how bright you want your marker lamps, coal stove flickering
fire, or rear end marker lights for your car. It can also be helpful to make
the charge on the capacitor last longer. The capacitor will stay charged for
around 30 seconds when you have the decoder set to the default of 100%
brightness, but if you lower this to 50% the capacitor will stay charged for
over 90 seconds. This can be helpful for analog operation where you may
have short station stops, and want the lights to stay lit while stopped at the
station.
CV 55 adjusts the F0 (f and r) outputs while CV 56 adjusts the FX5 and FX6
outputs. The number entered into CV 55 or 56 will be the overall percentage
of brightness. For example a value of 50 would make the lights half as bright
as the default, which is 100. A value of 100-255 will set the output to 100%
brightness while a value of 0 will disable the output.
Setting the Flash Rate and Hold Time
CV 59 is used to adjust the flash rate of the Hyperlight effect and has a range
of 0-15 with 15 being the slowest flash rate. When the Grade Crossing Logic
feature is enabled, CV 60 is used to adjust the length of time (in seconds)
an effect will remain active after the whistle key is released. CV 60 can be
programmed with any value between 0 and 15.
Example, Mars Light with Grade Crossing Logic
In this example, we will configure the headlight output for use with an
incandescent bulb as a Mars Light with Grade Crossing Logic enabled.
Following the steps outlined above, we proceed as follows:
