Hook-Up

Install your device in compliance with the connecting diagrams in this manual. The device is protected against shorts and excessive loads. However, in case of a connection error e.g. a short this safety feature can’t work and the device will be destroyed subsequently. Make sure that there is no short circuit caused by the mounting screws or metal.
NOTE: Please note the CV basic settings in the delivery state.

Product description

The mXion USD is a very small but powerful 6 ch. switch decoder for universal use.

He offers various programmable functions like flashing, pairwise flashing and over
16 other effects (18 in total). This includes simulations such as TV, Neon, Petroleum, Welding, US lights and much more. The effects are great for street lamps, even entire streets, houses and much more and also with the SDF combined!

The special thing about this decoder is that integrated SDF. With this system (known from our FSD decoder) you can now stationary
the 6 channel use for chases (14 integrated), fun fair (2x integrated), lively house, construction site and much more ideal for funfairs, buildings and so on.

The 6 turnout addresses can be independently programm and do not need each other be following. In addition to the usual CV programming also supports the module a programming switch to quickly get the addresses to be able to change.

The module supports DCC and Motorola, so this decoder can be used universally.

Fairy mode
Another special feature of the decoder is the SDF and thus the fair, running lights and site feature. This is described in CV19 set. Switched via F1 (CV21). So owns the decoder 15 chases with various patterns, construction site running lights, speed cameras and much more. On top of that
2 finished fairground events integr. (15/16).

Programming lock

To prevent accidental programming to prevent CV 15/16 one programming lock. Only if CV 15 = CV 16 is a programming possible. Changing CV 16 changes automatically also CV 15.
With CV 7 = 16 can the programming lock reset.

STANDARD VALUE CV 15/16 = 245

Programming options

This decoder supports the following programming types: bitwise, POM and CV read & write and register-mode.

There will be no extra load for programming.

In POM (programming on maintrack) the programming lock is also supported. The decoder can also be on the main track programmed without the other decoder to be influenced. Thus, when programming the decoder can not be removed.

NOTE: To use POM without others decoder must affect your digital center POM to specific decoder adresses

Programming binary values

Some CV’s (e.g. 29) consist of so-called binary values. The means that several settings in a value. Each function has a bit position and a value. For
programming such a CV must have all the significances can be added. A disabled function has always the value 0.

EXAMPLE: You want 28 drive steps and long loco address. To do this, you must set the value in CV 29 2 + 32 = 34 programmed.

Programming switch adress
Switch addresses consist of 2 values.
For addresses < 256 the value can be directly in address low. The high address is 0. If the address is > 255 this is as follows (for example address 2000):
2000 / 256 = 7,81, address high is 7
2000 – (7 x 256) = 208, address low is then 208.

About the programming button:
Change the position of the slider during operation, the point output 1 will alternate in 1 sec. clocking.

Switch on the desired control unit on the control unit switch address, then output 1 will alternate faster (0,5 sec). In order to the address has been accepted correctly and all 3 outputs are numbered.

You can now put the slider back on the switch the original state. The protocol can not be changed during operation become!

Reset functions
The decoder can be reset via CV 7. Various areas can be used for this purpose. Write with the following values:

• 11 (basic functions)
• 16 (programming lock CV 15/16)
• 33 (function outputs)
