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. 

 

Standards 

LaisDcc decoders are designed to comply with NMRA and MOROP standards and compatibility, 

and will work well and reliably with all standards compliant control systems 

 

Addressing  

You may choose any number between 1 and 9999. If your controller supports “aliasing” you 

can of course also allocate a name to your locomotive. If you choose to use a short address 

enter only the number itself – there is no need to add any zeros before a short number. 

 

Because we know that many of our decoders will be used by new or inexperienced modelers 

we have limited “short address” changes to the programming track, as entry level controllers 

are not always easy to use and often lack reliable “Program on the main” abilities. 

 

Adjustment   

All programming with the exception of short addresses can be set either on the main or on the 

programming track. Many adjustments to decoder settings can even be done while the loco is 

running on your layout. 

 

Motor Control  

LaisDcc decoders support adjustment of motor control parameters that may be required 

 

to set-up starting, acceleration characteristics and momentum. Speed tables are supported. 

 

 

Wire length:

  All our decoders are with 150mm wire length, if it’s too long for your loco/train, you can easy to cut to 

match with your loco. We do hope our decoders can meet all fans’ requirements, and the fans do not need to 

extend the wires

 

by themselves. Because we have been reported that a lot of fans that used a lot of other 

decoders from other brands before and had to extend the wires frequently, most of the time for steam locos.
