You can program the following registers:
Register Function
CV1 Loco address
CV2 Starting voltage
voltage for speed setting 1 - if loco starts only at a
higher speed setting, increase value.
CV3 Acceleration (1 = fast, 255 = slow)
CV4 Braking (1 = fast, 255 = slow)
CV5 Max. voltage
Voltage for highest speed step - if a lower top speed is
desired, decrease value.
CV5 after input of CV6 (when programming with older
55015) function value for CV to be programmed
CV6 CV to be programmed (when programming with older
55015)
CV29 NMRA configuration
Bit programming
Bit 1: direction, 0 = normal, 1 = reversed [0]
Bit 2: speed steps, 0 = 14 (LGB), 2 = 28 [0]
Bit 3: analog operation, 0 = not possible, 4 = possible [4]
Bit 4: not used [0]
Bit 5: speed steps, 0 = factory-programmed,
16 = user-programmed [0]
Bit 6: address area, 0 = 0-127 (LGB), 32 = 128-10039 [0]
To program, add the values for the individual Bits and
program the resulting function value.
Hint: To program a loco to reversed direction of travel
(for example, F7 A-B-A combination), program
function value 5.
Attention! Loco addresses 128-10039 and 28 speed
steps cannot be used with LGB MTS).
CV49 Voltage for function terminal F1
(depends on loco model, do not change, as functions
can be affected or destroyed)
CV50 Voltage for lighting terminals (see CV49)
CV51 Command for function terminal F1
0 = lighting button 9
1 = button 1 (buttons 2-8 not used)
9 = button 1 (buttons 2-8 used as well)
10 = button 2
11 = button 3
12 = button 4
13 = button 5
14 = button 6
15 = button 7
16 = button 8
64 = lighting button 9 (on only when loco is reversing)
65 = button 1 (on only when loco is reversing)

Bit programming
Bit 1: hand-off function, 0 = off, 1 = on [0]
Bit 2: MTS Back-EMF, 0 = off, 2 = on [2]
Bit 3: analog Back-EMF, 0 = off, 4 = on [0]
Bit 4: not used [0]
Bit 5: 0 = F1 constant, 16 = F1 flashing [0]
Bit 6: 0 = F2 constant, 32 = F2 flashing [0]
Bit 7: sound function (0 or 64) [0]
Bit 8: sound function (0 or 128) [0]
To program, add the values for the individual Bits and
program the resulting function value. The values for
Bits 5-8 vary between locos. The values for your loco
can be read using the 55045 MTS PC Decoder
Programming Module.
Hand-off function on: When operating with 55015, you
can adjust direction and speed for two seconds after
selecting a moving loco without causing the loco to stop.
Reset factory pre-set values for CVs

Voltage for function terminal F2
(depends on loco model, do not change, as functions
can be affected or destroyed)
Command for function terminal F2 (see CV51)
Pause time (analog operation)
(0.5 seconds x function value)
When the polarity of the analog track voltage is
reversed, the loco waits for the programmed time
period, then accelerates in the new direction
Back-EMF: Max. adjustment factor
Specifies the max. increase or decrease of voltage
applied during each time interval (programmed in CV61)
1 = small steps, 255 = large steps
The factory pre-set values of CV60 and CV61 are
optimized for LGB motors.
Back-EMF: Adjustment frequency
Specifies how often per second the motor voltage is
adjusted - accordingly, the loco will react to curves and
grades immediately or with a short delay
0 = immediate adjustment, 255 = maximum delay
Back-EMF: Max. Adjustment
Limits the total adjustment in motor voltage. If there is a very large
