Titan lighting effects

 

This page started out with a friend wanting to use the overhead rotating beacon effect, and it is going to morph into something I'm sure.

I'm just filling it in as we go.

Programming lighting features / ports / etc.

The overall scheme is:

  1. There are physical connections, called PORTS, where the voltage can vary and be controlled.
  2. There is a way to map FEATURES to the ports
  3. There are further things that can be done to modify the behavior.

Ports

The LS Titan has 12 ports and from what I have found they are all programmable, but more later.

The table below indicates which screw terminal number on what header has what port. These are J1, J2, J3

Map FEATURES to PORTS

So the next step is to map a lighting FEATURE to a port. I have listed the default FEATURE mapping, but be aware I have not checked that this is right for every Titan file.

For my friend, I made an inventory of the features he wants:

  • 2 - front ditch lights
  • 1 - front headlight
  • 1 - rear headlight
  • 1 - cab light
  • 1 - number boards
  • 4 - rotating overhead beacon (using 4 LEDs)
  • 2 - possible smoke or mars/gyralite 2nd headlight beam. (1 front 1 rear)

That's 12 ports. Now the loco is a SP GP-60, and he might opt to not have smoke, and that would free up 2 ports. The model has dual headlights, and I have seen prototype locos where one of the headlights is on solid, and the other a mars/gyralite.

Let's map!

Refresher: QSI uses "indexed" CVs, so when you see CV xxx.yyy.zzz in the manual, you use the index registers CV49 and CV50 for the yyy and zzz numbers.

So to map a FEATURE to a PORT, you set CV 115.yyy.zzz

  • CV115 = port number
  • yyy and zzz are feature coded
  • setting CV115.yyy.zzz to zero disables the feature
  • disable a feature on a port BEFORE you map a NEW feature to a port
  • remember that if you program in OPS mode, you must cycle power to the decoder to see the change

 

 

see page 410 in the manual, section 7.1

basically CV115.x.y is what is used where x and y indicate the lighting feature

see the chart on page 411
