Special CV for programming beyond CV99 on old system PLUS decoder LOCK/UNLOCK feature.

For Roco Lokmaus users and any other systems which can only address CVs up to 99. Set bits 0 or 1 to address CVs over 99. Not necessary on most DCC systems.

CV53=66: programming and feedback off (LOCK decoder from accidental re-programming.set to 77 to UNLOCK)

CV53=77: programming and feedback on (UNLOCK decoder for programming. after setting to 66 previously)

CV53=0: 0-99 programmed CV value i.e. CV actually programmed is the one requested

CV53=1: 100+ programmed CV value i.e. with CV53=1, any other CV programming goes to the CV+100, so CV8 would actually be sent to CV108 etc.

CV53=2: 200+ programmed CV value

Bit 0 (1) - OFF = 8 functions, ON = 14 functions (MAN-bit) refers to F0-F12, btw CV33-CV46 free assignment.

Bit 1 (2) - ZIMO train number impulse on / off

Bit 2 (4) - strong / normal / weak switched with F1, effective only when CV110 is active, and dimmable via CV54

Bit 3 (8) - strong / normal / weak switched with F2, effective only when CV110 is active, and dimmable via CV54CV137

Bit 4 (16) - ZIMO speed contrl - dependent train control 0 = off 1 = on

Bit 5 (32) - Start sequence (Sound Slots 21-23) is played before motor starts to spin - useful for diesel engines in particular as a rev-up sound before phsyically setting off. Beware of using this feature though, as it actually stops the 'standstill' background noise whilst the start-up sound is being played, which can sound a bit odd unless you mix/blend the standstill sound into the start-up sound!

Bit 6 (64) - Set ON if you want to control additional functions using F4 - press twice for F5, 3x for F6, 4x for F7 (useful if your controller does not have access to many functions directly)

Bit 7 (128) - 32kHz frequency motor control from software version 41, factory Bit7 = 0 16kHz

Bit 0 (1) - Direction: OFF=normal; ON=inverted

Bit 1 (2) - Speed steps: OFF=14/27; ON=28/128

Bit 2 (4) - Operating mode: OFF=digital only; ON=DC and Digital

Bit 3 (8) - not used

Bit 4 (16) - Speed curve: OFF=default speed curve using CVs 2, 5 & 6; ON=free speed curve using CVs 67-94.

Bit 5 (32) - Address selection: OFF=1-127 (uses CV1); ON=128-10240 (uses CV17+18)

Bit 6 (64) - not used

Bit 7 (128) - not used

Activated with CV29 bit 4 is set.

Default values: 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99, 108, 117, 126, 135, 144, 153, 162, 171, 180, 189, 198, 207, 216, 225, 234, 243, 252

Shunting mode may be switched on/off via appropriate function mapping - see CT extended function mapping document for more information

Only active if bit0-bit2 set

Bit 0 (1) - effects of CV3 and CV4 are disabled when shunting mode activated

Bit 1 (2) - maximum speed is halved

Bit 2 (4) - reverse is 65% of maximum speed (regardless of shunting mode) - applies from SW Version 40 or later

Bit 3 (8) - brakes with diode 4:1 is active - see also CV 162

Bit 4 (16) - brakes without diode

Bit 5 (32) - not used, must always be 0

Bit 6 (64) - means that the "Rangierfunktion" acts as a command button that is, that the automatic train control system (brake or diode and HLU) - (equivalent to the MAN key = manual)

Bit 7 (128) - short burst of idling, returning to normal speed

A combination of 33-46 and 163-176 provides full mapping of all the SL51-4's 8 function outputs and sound effects, as well as shunting mode and main running sounds. You really need to calculate the values for both ranges of CVs at the same time to map the functions properly.

Output 0 (white wire)

0 - No effect

1 - Flashing

2 - Flash-pull

3 - Single pulse strobe

4 - Double Flashing strobe

5 - Headlight (brightness between maximum and PWM value in CV 114)

6 - Ditch light left (brightness between maximum and PWM value in CV 114)

7 - Ditch light right (brightness between maximum and PWM value in the CV 114)

8 - Rotary beacon (brightness between maximum and PWM value in the CV 114)

9 - Gyralite (brightness between maximum and PWM value in the CV 114) - can also be used for firebox glow

10 - Mars light

11 - Soft-start

12 - Brake sparks (short flash activated only when the loco comes to a stop)

For output when forward only, add 64 to the above value e.g. 1 + 64 = 65 flashing on Forward only. For output when in reverse only, add 128 to the above value e.g. 1 + 128 = 129 flashing on Reverse only. If neither 64 nor 128 is added, it is assumed that the effect should be active for both forwards and reverse.

CVs 155 -161 provide the same effects for each of the other function outputs.

CV49=0 gives 4 cylinder steam engine

Bit 0 (1) - set if you use a Reed switch for wheel synchronising for steam engines - see also CV133=number of Reed Contacts - pulses per stroke e.g. CV133=1 means 1 stroke/pulse

Bit 1 (2) - set for Diesel or Electric loco - uses the AUTO slots - recommended approach for diesel/electric

Set both Bits 0 & 1 (value 3) for diesel and electric sounds that use Sound Slots 00 to 11 (must all be filled with sounds) - this is deprecated by the use of the AUTO sound slots (also known as Slots 1000-3000), so is not recommended.

Bit 2 (4) gives 2 cylinder steam

Bit 3 (8) gives 3 cylinder steam

Bit 4 (16) - no steam strokes during downhill/deceleration (only idle sound)

Bit 5 (32) - evaluate the LGB pulse from F1

Bit 6 (64) - play no sound between stand-still and running e.g. whistle (Slots 21-23 and Slots 24-26)

Bit 7 (128) - no sound between running and stand-still e.g. brakes (Slots 27-29 and Slots 30-32)

Values depend upon software version:

Old versions have range 0-3 only (0 gives no sound, 3 gives maximum volume). Newer versions have range 0-63 (63 being maximum). Expect that future versions may range from 0-255.

Volume & Repetitions for sound effect 8

or

Strong time (CV39 or older)

From SW version 40 onwards CV 129 has this meaning:

Volume & Repetitions for sound effect 8 (Slots 72-76): bits 0-1 specify volume; bits 2-4 for number of repetitions of middle sound (Slot 74); bits 5-7 define number of repetitions of sound effect overall. If the 'Alternate' sounds are activated, this applies to sound effect 16 instead (Slots 112-116)

Note that it is not possible to individually control the volume or looping of sound effects 9-16 (Slots 77-116) - they take on the settings for the equivalent effect in sounds 1-8.

Prior to SW version 40, CV 129 had the following meaning: Strong time: time that the acceleration chuffs sounds (Slots 0-3) continue after strong acceleration (0.5 seconds units).

Stroke speed at Step 1 (LOW byte in CV133, HIGH byte in CV134): time between two steam strokes at speed step 1 in seconds.

This can be a large number, so is defined using 2 CVs (133 and 134 with the LOW byte in CV133 and HIGH byte in CV134).

Calculated via the formula: K = 1476 / time (1476 is a constant always used for this calculation by the decoder)

Example 1: K=153 gives approximately 9.6 sec between chuffs

Example 2: if 20 seconds wanted between chuffs, so K = 1476 / 20 = 73.8 rounded to 74 gives CV133 = 74, CV134 = 0

Example 3: if 3 seconds wanted between chuffs, so K = 1476 / 3 = 492. Since K > 256 we need to use 2 bytes, so split low byte and high byte: 492 / 256 = 1.927875 thus CV134 = 1 (rounded down), CV133 = remainder i.e. 492 - (256 * 1) = 236

If the corresponding sound function is activated, it will first play its 1st and 2nd Slots. After that, Slot 3 is repeated until the feature is turned off. After requesting off, it plays closing 4th and 5th Slots.

Bit 0 (1) - for looping of Sound 1 (Slots 37-41)

Bit 1 (2) - for looping of Sound 2 (Slots 42-46)

Bit 2 (4) - for looping of Sound 3 (Slots 47-51)

Bit 3 (8) - for looping of Sound 4 (Slots 52-56)

Bit 4 (16) - for looping of Sound 5 (Slots 57-61)

Bit 5 (32) - for looping of Sound 6 (Slots 62-66)

Bit 6 (64) - for looping of Sound 7 (Slots 67-71)

Looping for Sound effects 8-16 cannot be configured - they are not looping.
