ZS90AB CLASS 90 ZIMO ACTIVEDRIVE SOUNDFILE FOR BACHMANN 90

CV

Designation

Range

Default

Description

1

Short 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

40

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

Manufacturer ID

and factory reset

Read Only

145

= 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

14

This means that bits 1,2 and 3 are turned on.  The loco runs on 28/128 speed steps, DC enabled and RailCom active.

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.

286

overrun sound volume for clank

0 - 255

50

Higher the number louder the clank
