Basic 3-Head Signal Decoder


The CESM signal controller board is custom built to control many different signal configurations.

New in all units shipped from now on are a strip of female headers to mate with our new sigDoc bases.

As a companion to our signals, we designed an innovative low-cost decoder, costing a third of comparable decoders, that offers the following advantages:

  • Adjustable color blending using CV values in the decoder to achieve proper color blending. No more mixing Red and Green to get an incorrect shade of yellow!
  • Prototypical vane movements and fading can be replicated simply by changing CV values in our decoder!
  • Compatibility with both common anode AND common cathode LED's if you want to use out controller board for your own signals!
  • Nine individual outputs on the controller board control up to three of our searchlight signals... It also works with RGY searchlights, standard 2-, 3-, and 4-element signal heads, color position/position signals, and more, all easily configurable through simply changing CV values.
  • Programming is easy - you don't need to connect the decoder to a programming track, simply install the included jumper and program on the main!
  • Integrated, low current draw, power supply allows easy installation - connect the decoder to your signal leads, plug in your track power, and start programming!
  • On-board current limiting resistors allow easy wiring.

The board comes stock with the required 560 ohm current limiting resistors; please contact us if you need 0 ohm resistors for your application and we'll throw some in so you can switch them out.

We will continue to expand more capability as time goes on, and firmware upgrades will be available from time to time that will make the boards better and better. You will be able to program the upgrades yourself with an ISP programmer.

Instructions are available in the support section of our website.
