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

Switch loads between A1-A8 and common + pole.
Use with 3-wire switches the common + pole as the center line.
Not use 3 pole LGB drives!
Also in switch mode (CV29 Bit 7 = 1) it’s possible to use DEC+ as common pole for lanterns e.g.
Not use 3 pole LGB drives!
Up to 4 switches and up to 8 consumers as lamps or engines are controllable!

Product description

The mXion VKW is a strong 4 channel switch decoder he can optional work in loco mode with 8 function outputs.
The four points are also independently of one another and freely addressable.
For this purpose, dimming and time units.
Here are the special features as with the mXion AKW that one integrated 3-way switch is implemented. This controls
3-way switches so that always has a defined direction of the soft takes place and derailments can be eliminated. Fit the switch to „straight“ if using this mode or use  CV 49 Bit 2/3 = 1.
The rear tongue automatically switches on „straight“ when the front is operated.
Switches one the front tongue back again, so also takes the rear tongue again the old direction. If the front tongue is on „branch“ and the rear tongue is now switched and the anterior tongue in the appropriate direction, so that on the one hand there are no derailments of vehicles and on the other hand the operation of the 3-way switch is simplified. So you can use the address for the switch the front tab „branch right“ and with the address for the rear tongue  „straight“ or „branch left“. The other tongue
will automatically so that does not must happen.
Another highlight of the VWK is the setting for decoupling tracks. Here you can create a corresponding function output (A7 to SW1 and A8 to SW2 bound in this mode) CV 49 Bit 0 and automatically with of the switch.
The advantage ist hat the luminous “E” of the LGB® decoupling track as the decouple is active. Now, weather the decouple is still disengaged or coupling.
Ideally, the two modes, complement each other with the mode for defined position. The outputs of the switches switch
automatically to „stop“ or „branch“.
This hast he advantage that signals on red, decoupling tracks to normal and turn switches to „branch“ after the system has been switched on.
So you always have a defined starting position.
TIPP: Use the global switch address in CV200/201 to select all route addresses (SW1-SW4) automatically sequentially. Write the address for SW1 in CV200/201 write CV201 (address byte high) first then CV200 address byte low. According to describe of CV200, SW1-SW4 will be consecutive where SW1 is the address of CV200 and CV201 and SW4 accordingly the address of SW1 + 4.

Contact inputs

The decoder offers the option of the switch outputs via contacts (manual) to be able to switch. The contact inputs are protected against positive voltages and switch to ground (DEC-).
With the contact inputs it is possible div. How to do switching tasks e.g. switching a turnout via track contacts. For example turnouts can be used switched or even direction-dependent be switched that inverse as well with double direction. That means that one train with a solenoid first K1 afterwards K2 of the output is actuated and the switch switches in a corresponding direction. The direction is invertible via CV 117.
Also, the contact inputs provide the possibility this as a limit switch to turn off a feature to use.
Continue to work with the contacts all turnout settings such as the inversion of individual outlets (switching right/left) etc.

Turnout-Routes

The decoder supports the usual turnpike from the central unit or handset to be sent.
As a one-off extra, the decoder supports manual switch routes. That is one can use 2 CVs a separate – independent set addr. for a route.
About another CV can be specified which of the existing points exits to be used for the road. A 4th and last CV gives the switch direction in the process. In total 3 of these assigned to manual routes. The CVs are from CV30 and upper.
Now you can by a separate – from the switch outputs independent address trigger the command that the decoder the before set route switches.
This system is important for control units that do not handle any routes and just with one click a road to go!

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 = 140

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 main track) 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 addresses

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 address

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.
• Program these values into the SW1-SW4 CVs.

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“ (automatically 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) = 189; CV 18 is then 189.

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)
• 22 (function outputs)
• 33 (switch outputs)
