Description
1
Sort Address
1 - 127
3
Active when Bit 5 in CV29 = 0
2
Start Volts
1 - 252
1
Value at speed step 1. Only applies if Bit 4 of CV29 = 0 otherwise the individual speed table is active.
3
Acceleration
0 - 255
30
Multiplied by 0.9 equals time in seconds from stop to full speed.
Influenced by sound project.
4
Braking
0 - 255
100
Multiplied by 0.9 equals time in seconds from full speed to stop.
Influenced by sound project.
5
Top Volts
0 - 252
1
Level applied to the highest speed step in use. Value 0 and 1 = max. Bit 4 in CV # 29 has to be 0 or the individual speed table is active.
6
Mid Volts
1
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
8

= ZIMO
Setting CV 8 to a value of 8 or 0 will return all CVs to the manufacturer’s default settings. Address = 3
17 & 18
Long Address
128 - 10239
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).
29
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 - 63
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
266
Volume
0 -255
65
The recommended range for use without distortion is 0 – 65. Settings above 65 are available subject to experimentation.
267
Chuff Frequency with virtual sensor for steam sound.
0 - 255
70
Active if CV268 value = 0 (Default)
Sets the duration between chuffs; lower settings = more chuffs.
268
overrun sound volume for clank
0 - 255
50
Higher the number louder the clank
Warnings
Fit 21 pin decoders yellow component side upwards
Do not leave wires connections bare if modifying wiring to fit your installation requirements. Always use heatshrink insulation. Bare wires kill decoders.
Stay alive capacitor wires blue and grey. Blue to blue or black +ve (unmarked) side of cap and grey to grey –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 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.
The idea of Digitrains was conceived over the dinner table and grew very slowly as doubts calmed missionary zeal. We finally took the plunge in January 2005 and are fortunate to be dealers for some of the best and most user friendly DCC equipment available.
