Titan lighting effectsThis page started out with a friend wanting to use the overhead rotating beacon effect, and is intended to walk you through customizing lighting effects. It's not done yet.Programming lighting features / ports / etc.The overall scheme is:There are physical connections, called PORTS, where the voltage can vary and be controlled. They are spread out over the 3 screw terminal connectors.There is a way to map FEATURES to the ports, these CVs are on the PORTS page of CV ManagerThen you can map how these FEATURES are configured, on the FEATURE CONFIG tab of CV Manager. There are lighting features, sound features, etc. We will just talk about lighting features here, there are tabs for:HEADLIGHTSMARS lightsDITCH lightsOHBL (OverHead Beacon Light)Strobe lightsNumber BoardsMarker lightsTruck and Step lightsCab lightsEngine room lightsFirebox lightsThere are further things that can be done to modify the behavior:map features to F buttonsmap features to the direction and movement of the loco.PortsThe 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 , and J3, pay attention to the colors so you are on the right header, this is a common error. (Ask me how I know!) portheaderpin1J1a42J1a93J2a84J2a125J3a16J3a27J3a38J3a49J2a1010J2a1111J3a812J1a8 Map FEATURES to PORTSSo the next step is to map a lighting FEATURE to a port. I have listed the advertised 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 lights1 - front headlight1 - rear headlight1 - cab light1 - number boards4 - 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.The Below mapping is an EXAMPLE portpinsteam featurediesel featureproposed for 4 LED beacon on GP601J1a - 4front headlightfront headlightsame (front headlight)2J1a - 9rear headlightrear headlightsame (rear headlight)3J2a - 8front mars lightfront mars light rotary beacon 14J2a - 12unassignedrear mars light - diesel rotary beacon 25J3a - 1front markersfront left ditch lightsame (left front ditch)6J3a - 2number board lightsfront right ditch lightsame (right front ditch)7J3a - 3rear markersrear left ditch light number boards8J3a - 4unassignedrear right ditch light rotary beacon 39J2a - 10firebox 1 / smoke fanfront overhead beaconsame (smoke fan)10J2a - 11front cab lightrear overhead beaconsame (cab light)11J3a - 8firebox 2unassigned rotary beacon 412J1a - 8rear cab / smoke heaterrear cab / smoke heater same (smoke heater) 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.zzzCV115 = port numberyyy and zzz are feature codedsetting CV115.yyy.zzz to zero disables the featuredisable a feature on a port BEFORE you map a NEW feature to a portremember 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 7.1basically CV115.x.y is what is used where x and y indicate the lighting featuresee the chart on page 411
