F2 Brake key
When closing the throttle the loco will coast and decelerate very slowly. To slow the train press F2 and the brakes actually work speeding up how fast the loco slows down just like a real brake control in the cab.

A useful value for CV 6 is ¼ to ½ of the value in CV5
|
1
Default = about 1/3 of top speed
|
Entered value = internal speed step assigned to the cab’s centre speed step (=step 7,14 or 63 according to the number of speed steps selected: 14, 28 or 128)
Bit 4 in CV # 29 has to be 0 or the individual speed table is active

Setting CV 8 to a value of 8 or 0 will return all CVs to the manufacturer’s default settings. Address = 3

|
Long Address
|
0001-9999
|
0
|
The long 5-digit primary address (greater than 127). This address is only active when Bit 5 in CV 29 is on. Otherwise the address entered in CV 1 is active (127 or lower).

Basic Configuration
CV #29 is calculated by adding the value of the individual bits that are to be “ON”:
Values added together to turn Bits “ON”:
Bit 0: 1
Bit 1: 2
Bit 2: 4
Bit 3: 8
Bit 4: 16
Bit 5: 32
Bit 6: not used
Bit 7: not used
|
0 - 128
|
6
This means that bits 1,2 and 3 are turned on. The loco runs on 28/128 speed steps, DC enabled
|
Bit 0 - Train direction:
off = normal, on = reversed
Bit 1 - Number of speed steps:
off = 14, on = 28
Note: 128 speed steps are always active if corresponding DCC packets are received!
Bit 2 - DC operation (analog): *)
off = disabled on = enabled
Bit 3 - RailCom („bidirectional communication“)
off = deactivated on = activated
Bit 4 - Individual speed table:
nff = CVs # 2, 5 and 6 are active.
on = individual speed table is used as set in CVs 67 – 94.
Bit 5 - Decoder address:
off = short address as per CV 1
on = long address as per CV 17+18

The recommended range for use without distortion is 0 – 65. Settings above 65 are available subject to experimentation.

|
Chuff Frequency with virtual sensor for steam sound.
|
0 - 255
|

Active if CV268 value = 0 (Default)
Sets the duration between chuffs; lower settings = more chuffs.

|
Higher the number louder the clank

Warnings
Do not leave wires connections bare if modifying wiring to fit your installation requirements. Always use heatshrink or other insulation. Bare wires kill decoders.
MX645 Stay alive capacitor wires blue and grey. Blue to blue or black +ve (unmarked) side of cap and grey to grey striped –ve (marked -) side. Then insulate with heatshrink. Wrong way round will blow capacitor!
Speaker wires not polarity sensitive but ensure well insulated as short circuits on speaker output will blow the amplifier and this is not covered on the warranty as it isn’t a manufacturing defect but considered as mishandling.
Please be sure you are confident working in your locomotives and have the necessary skills to fit the decoders. If not seek the services of a professional.
Troubeshooter
If decoder appears faulty at any time carry out a project reset setting CV8 to 8. This will restore your decoder to as shipped condition. It will also reset address to 3 again, original sounds will not be lost.
