Programming the CV29
The CV29 is used for the setup of the decoder. It defines the behaviour of the decoder according to the
facilities of the central unit and to your wishes. The CV29 sets up the following features:
q
the sense of driving
q
the speed step mode
q
the automatical recognition of the DC operation (by this way you can use DC to stop the loco in front
of a red semaphore)
The valid values for the CV29 are at most of the locos:
0
sense of driving: normal
speed step mode14
digital only
1
sense of driving: inverted
speed step mode14
digital only
2
sense of driving: normal
speed step mode28
digital only
3
sense of driving: inverted
speed step mode28
digital only
4
sense of driving: normal
speed step mode14
digital and DC
5
sense of driving: inverted
speed step mode14
digital and DC
6
sense of driving:
normal
speed step mode
28
digital and DC (default)
7
sense of driving: inverted
speed step mode28
digital and DC
Professional Programming Procedure
Press the button ‘P’ for at least 8 seconds (this time can be changed by the menu C5 see page 28). You
enter the professional programming mode. The display shows ‘EP’ and both points of the display flash
simultaneously. Release ‘P’ and changes to indicates ‘01’ for the CV01 the first memory of the decoder.
If you want to program a different CV then you select this CV using the ‘up’ and ‘down’ buttons e.g. the
CV04 to program the deceleration delay. The range of CVs you can program by the Lokmaus®2 is from
01 to 99 with values from 00 to 99.
Press ‘F1’ to confirm your selection and read the decoder or ‘F4’ to confirm and write it.
If you press ‘F1’ the display shows ‘FS’ to indicated the reading procedure and after that it shows you the
result.
IMPORTANT:
The actual amplifier 10761 is not able to read out the decoder, therefore you get an er-
ror-message in the display of the Lokmaus®2. For the future ROCO plans to develop a device that is
more powerful and supports to read the decoder. If you use the Lokmaus®2 together with a LZ100 and
LV101 by Lenz then you can read out the loco decoder already today.
If you select ‘F4’ to write the decoder then you must indicate the value you want to program by the but-
tons ‘up’ and ‘down’. By principle all values from 00 to 99 are programmable, but most of the decoders
only support a smaller range of values. ROCO decoder e.g. accept for the deceleration a range from 01
to 31. In this example you indicate 10 for the deceleration.
Pressing the button ‘P’ you start the programming procedure and the value is written into the decoder.
This procedure takes some time. The display shows ‘FP’ to indicate this procedure. After that the Lok-
maus ®2 returns to the selection of the CV and you can select the next CV in order to program it. At any
time during the programming menu you can cancel the procedure by pressing the ‘STOP’ button and
quit the menu without reading or writing the decoder.
The time you have to press the button ‘P’ to enter this programming mode can be defined by the menu
C5 and in the same menu it can be deactivated – so it can’t be used unintentionally by children – see on
page 28.
Programming Modes
There exist some different methods to transmit the programming information to the decoder: the ad-
dress-only-mode, the register-mode, the paged-mode and the direct-mode (direct CV-programming).
The
address-only-mode
can only determin the address of a loco. It was designed for very simple deco-
ders, that don’t support other features.
The
register-mode
(physical register mode) is the oldest method to transmit the programming informa-
tion to the decoder. The programming information are transmitted as commands for the loco addresses
120 to 127 and are accepted as programming information by every loco after a reset (therefor you
should not use the addresses 120 to 127 to control a loco). The selected address defines which kind of
information (which memory of the decoder) is accessed. So you have a maximum of eight memories
