Programming the LS-DEC Notes
This is paraphrasing the official instructions which I found confusing, partially by the English and partially by the sequence.
Before you start...
- From version 4 the Light-Signal Decoder contains a third Jumper (J3) which has to be inserted for programming the unit.
- The LS-DEC modules can control four 2,3 or 4 aspect signals. With the module positioned with
track power on the left and transformer power on the right:
- The signal addressing order goes Bottom Left, Top Left, Top Right, Bottom Right.
- Each uses one address for two aspect signals.
- Each uses two addresses for three or four aspect signals.
- If using feathers, only one signal per side can be used.
- The base address you use for either side must be divisible by 4 plus 1. e.g.
961 (960 which is divisible by 4, plus 1)
Address Signal 961 & 962 Bottom Left 963 & 964 Top Left 965 & 966 Top Right 967 & 968 Bottom Right - The assigning of digital addresses has to be done for each module separately. (A module is left side or right side)
- When programming, using the above example, you can use any of the four addresses on whichever side you are programming. e.g. For the left side (first side) you can use 961 to 964 and for the right side (second side) you can use 965 to 968
The programming 2, 3 or 4 aspect (without feathers)...
- Power off and insert jumper J3
- Power on and set your hand controller points address to any of the left hand addresses and ensure that the selection is minus and NOT plus.
- Repeat with the right had address ensuring the selection is minus and NOT plus.
- Press S1 and two LEDs on the left will flash at a 1.5 second intervals.
- Select the first address and press the plus key. This sets all the left hand side addresses and the LEDs flash slightly faster
- Press S1 and two LEDs on the right will flash at a 1.5 second intervals.
- Select the second address and press the plus key. This sets all the right hand side addresses and the LEDs flash slightly faster
- Press S1 again to store the settings.
- Power off and remove the jumper to protect the addressing.
Test and ensure all is correct.
The errors I originally made were getting the correct address and ensuring, when you program the address, you use the plus key. If you use the minus key you program the signals with feathers (see original documentation if this is what you require).
