LaisDcc Decoder Manual
We have released new manual V2 at http://laisdcc.com/LaisDcc_Decoders_Manual_V2.pdf
Thank you for purchasing LaisDcc decoders. We are sure that out of the packet, it will do everything you
need and deliver smooth, reliable results with a minimum of fuss because from the very beginning what we
set out to do was to create a versatile, easy to install and simple to adjust range of products that offer
exceptional value and top quality performance when used with any NMRA compatible control system.
Similarly we have done our best to make this manual direct and easy to understand so you will be
encouraged to learn a little about how simple it is to do much more than just set addresses and so be able to
enjoy the process and benefits of getting the best possible performance from your locomotives.
In its initial form, this manual will cover all of the basics, however there are so many special features
available from our decoders that we felt it best to limit this document to things that most modelers can do or
will want to do when they are comfortable with their control system...

General Specifications for LaisDcc decoders:
Power Handling:
All LaisDcc decoders have more than adequate power for any N, TT, HO, OO, On30 or similar modelling
scale. They are also suitable for many S or O scale models when powered with modern low current draw can
or coreless motors.
We set our decoder specifications at "Standards compatible" NMRA track voltages – please be aware that
while US based systems meet this specification all of the time, many EU made controllers will often have
track voltages well in excess of DCC standards recommendations and while our decoders will still perform
reliably and well irrespective of your systems actual output voltage, we do suggest that if it is higher than the
Standards say it should be then a slightly more conservative current draw rating should be assumed.
In general, providing your locomotive draws less than 1 amp consistently with an average train, then you
should use them with confidence. If your locomotive is old with an inefficient motor that draws more than ¾ of
our rated decoder power consistently, then we do suggest that when slipping or under excess load it may

- Page 3 Primary feature listing for LaisDcc decoders: These are the primary features of LaisDcc decoders however it is not intended as a comprehensive listing – for example, we detail here how many light functions there are, but we list the individual abilities of each of our lighting and auxiliary functions in a later section of this manual.
- Page 4 Silent Drive All LaisDcc decoders have high frequency silent drive for quiet, silky smooth running. Brake on DC All LaisDcc decoders support “Brake on DC”. To make it possible to use brake on DC you will need to turn off DC running. This is done by reducing the value already set in CV 29 by 4 (for...
- Page 5 DCC system brand, be either from 1 to 99 or from 1 to 123! (In line with the Standards, LaisDcc decoders will accept any number from 1 to 123 as a short address) This is important information as that means that any number between 100 and 123 can be interpreted as long or short depending on the DCC system brand.
- Page 6 Whilst locomotive manufacturers may not always follow correct color codes they do generally comply with the standards covering the use of “DCC ready” decoder sockets within locomotives, all LaisDcc decoder harnesses and connectors do meet standards, so you can approach their installation with confidence.
- Page 7 Wiring and description of functions and related wire color codes. All of the active (light or smoke etc) functions of LaisDcc Decoders can be remapped to any function button or to deliver a wide range of lighting types – directional or constant light, constant dim or rule 17 dimmable when stopped, flickering fire box, strobe , alternating ditch lights , pulsing dual mars lights , flashing beacons and more.

- Page 9 This is often called “function mapping” but that’s a little geeky so we prefer to call it “function allocation” In cheaper Decoders you have no choice, however all of our LaisDcc Decoder functions are able to be re- allocated to operate with a wide variety of function buttons, adding far more flexibility of use and giving you full control of how you operate.
- Page 10 Web:www.laisdcc.com E-mail:Sales@laisdcc.com Tuning and adjusting the motor control in your LaisDcc Decoder With the loco address set and locomotive tested, it is time to take advantage of the benefits of DCC. To do this we are going to change the way that the decoder tells the motor to run. This done by changing information stored in the decoder.
- Page 11 Try CV3 = 20, CV4 = 24, CV5 = 188, CV6 = 60, CV61 = 1 LaisDcc Back EMF self-adjusts & self-compensates for varying factors so it does not need changing for different motor types... however there are some useful options available for those who want the core BEMF benefits but with control changes to suit their needs.
- Page 12 (2) We need to set CV64 to set the Dimming level. The range for this CV is 0~15. We find the best range to use to dim LEDS is 1~6. We use 3 with our own locomotives. So... For CV 64, enter 3. 2002-2015 ©laisdcc Design in HK, Made in China...
- Page 13 Did you follow that OK> If so, then it is time to take a break & have a Play with Rule 17! LaisDcc decoders include a user editable speed table in 28 steps (the decoder interprets the gaps between each step in 128 mode). This allows you to tailor each individual speed step to achieve your own specific custom acceleration results.
- Page 14 (3) Help - I made a CV mistake. Now it won’t work. No problem! Just do a reset (CV8 to 2) and it will be back to the settings it had when you bought it. If in Doubt – always RESET by entering 2 into CV8 2002-2015 ©laisdcc Design in HK, Made in China...
