Southern Rail Models – Vlocity DMU Rail Cars
Function Mapping for the Lighting
In November 2014, Southern Rail Models released the V/LINE Vlocity DMU Sets, which includes the 21 Pin MTC socket for fitting a DCC decoder and a factory installed speaker. The model comes with LED headlights, red and white marker lights, ditch lights and interior carriage lights.
When Southern Rail commenced development of this model, they wanted to get the most lighting options available with the current range of DCC decoders on the market. Moving forward, the choice of the 21 Pin Socket was to enable the user to simply plug in a DCC Decoder without the need of any additional wiring or soldering for the lights or sound speakers on the model.
With the growing trend of installing sound into locomotives, the model is delivered sound ready. Being an Australian locomotive, a sound file is not available from any decoder manufacturer off the shelf, so a recording had to be made, and a DCC Solutions Custom Sound Project developed especially for the Vlocity. The only sound decoder at the time that was able to provide a custom sound project was the ESU LokSound V4.0. The DCC Solutions Vlocity sound project has since been upgrade for use with the ESU LokSound 5
With a high detail replica model of the Vlocity produced by Southern Rail, trying to reproduce how the lights operate as per the prototype became difficult, as the current decoders when the model was released simply didn't have enough light outputs. The internal light boards on the Vlocity have been designed for the use with the ESU decoders, allowing for the separate operation of Markers/Ditch Lights, Headlights, and Interior Lights.
While this light setup might not suit everybody, the good news is it can be changed to suit your own personal preferences.
All ESU decoders sold by DCC Solutions are already programmed for lighting and can be setup to suit your requirements.
How to Map the Lights to Function Keys
ESU LokPilot V4.0 (Non-Sound)
If you have purchased an ESU LokPilot V4.0 Decoder, the interior lights will not operate.
This is because AUX4 is not programmed by default to operate.
The function mapping of the ESU decoders is extremely complex. There are 640 CVs with 5120 possible combinations. They are all indexed CVs, which means to change 1 CV will require you to change 3 CVs in succession to complete the change.
For those who have access to the ESU LokProgrammer or use JMRI (Decoder Pro) it is a simple task of ticking checkboxes to active AUX4 onto a function button and writing the changes to the decoder.
But, there are many out there that do their decoder programming via their DCC System Throttle. As there a several DCC Systems on the market, please consult your manual on how to change CV values.
The lights will operate out of the box by default on the ESU LokPilot V4.0 as follows:
LIGHTS OUTPUT FUNCTION
Front Markers/Ditch Lights Front Light F0 or Headlight
Rear Markers/Ditch Lights Rear Light F0 or Headlight
Front Headlight AUX1 F1
Rear Headlight AUX2 F2
Interior Lights AUX4 Not Active
Mapping the Interior Lights on F3
Input these values into 6 CVs in the following important order:
Enter the value of 16 into CV31
Enter the value of 2 into CV32
Enter the value of 32 into CV426
Enter the value of 16 into CV31
Enter the value of 2 into CV32
Enter the value of 32 into CV442
Your interior lights will now operate on/off on F3.
Directional Headlights
The headlights do not operate directionally, only on/off. For those that would like directional headlights.
Input these values into 6 CVs in the following important order:
Enter the value of 16 into CV31
Enter the value of 2 into CV32
Enter the value of 0 into CV378
Enter the value of 16 into CV31
Enter the value of 2 into CV32
Enter the value of 0 into CV394
Your headlights will now operate by turning on F1 and F2, but will turn on/off with direction of travel.
ESU LokSound V4.0
DCC Solutions have pre-programmed the lights to operate correctly. If purchasing a decoder from us, you can specify how you would like the lights to operate, as we have several combinations.
The changes described for the ESU LokPilot V4.0 are not suitable for the ESU LokSound V4.0 Decoder that you may have purchased from your ESU Retailer, as the function mapping CVs will be different.
