General information

We recommend studying this manual thoroughly before installing and operating your new device.
Place the decoder in a protected location. The unit must not be exposed to moisture.
NOTE: Some funktions are only available with the latest firmware. Please make sure that your device is programmed with the latest firmware.

mXion PWD

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.

Connectors

The switch is analog and digital functional. Connect consumers to A1 and A2 (see pic). A1 is ideal for ceiling light, A2 for toilet or table lamps. Random control as well as inversion as well as continuous operation is possible, as well as effects.

Product description

The mXion PWD is 2 ch. function decoder.
It is ideal for all factory-lit-cars from LGB® suitable and can the existing electronics replace 1:1. The electronics are in the ground (for RhB cars) or in the toilet (for DB cars like IC, D-Train). The PWD also has a switch as a big puffer, so a trouble free operation is possible.
It is due the high functionality and performance. Due to the small dimensions, the module (also multiple) in locomotives, cars, or buildings will. With its high power output from to 1 Amps per channel it is ideally suited to even larger loards. Furthermore, the module supports a series of lighting and switching effects configured and freely customizable.
It is ideal for passenger cars to suit these to light up and with light effects to be equipped. The two channels can, for example, compartments separately lit. Train closing lamps. In analog mode, both outputs are full functionality also usable. In addition, both outputs can be dimmed.

The following picture shows the PWD installed into a RhB car, so that the old, fault-prone is replaced.
The connection can be screwed or soldered.

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.

Buffer control
A big buffer for several minutes is already integrated and is integrated by the also current is 500 mA, load current up to 2A.

Programming loco adress

Locomotives up to 127 are programmed directly to CV 1. For this, you need CV 29 Bit 5 „off“ (will set automaticly). If larger addresses are used, CV 29 – Bit 5 must be „on“ (automaticly if change CV 17/18). The address is now in CV 17 and CV 18 stored. The address is then like follows (e.g. loco address 3000): 3000 / 256 = 11,72; CV 17 is 192 + 11 = 203. 3000 – (11 x 256) = 184; CV 18 is then 184.

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)
