The Master - Slave system
In the new ROCO Lokmaus®2 digital system every Lokmaus®2 can be the Master (central unit). A Lok-
maus®2 plugged to the ‘master’ connector of the amplifier automatically becomes the master. The mas-
ter coordinates the complete system and generates the track-signal. In any case
only one Lokmaus®2
can be connected to this plug. Any Lokmaus®2 or other devices that are plugged to the ‘slave’ input of
the amplifier automatically become slaves. By the range of addresses here can be plugged up to 30 de-
vices. But due to the power consumption of the devices e.g. only 10 mice can be plugged.
If the master Lokmaus®2 is unplugged the system stops (because there is no more the track signal) and
the layout isn’t fed with current. The system looses all information and the smart search list is canceled.
The slave Lokmaus®2 may be unplugged during the session as often as you like without any interrupt of
the system or loss of information.
Function that are only available at the ‘Master Lokmaus®2’
Any Lokmaus®2 can be master or slave. Any setup you make at the individual Lokmaus®2 is stored but
at some setups only the stored information of the master is valid:
q
the smart search addresses (the smart search list) is stored here
q
the number of speed steps of the locos is memorized here
q
the master stores the position of the switches for the turnout keyboard 10770
The result is that you should remember which of your Lokmaus®2 is master and which are slaves. If you
exchange master and slave the setup of master and slave could be different. The three setups listed
above can be done at any mouse and are saved at any mouse but only the setup of the mas-
ter-Lokmaus®2 takes effect. The setup inside the slave Lokmaus®2 is not valid, but stays memrized
and takes effect if that Lokmaus®2 becomes the master. By that way you can store different setups (e.g.
different speed-steps for locos) insinde different Lokmaus®2.
Setting up the speed steps (14, 28 or 128 speed steps)
You can set up the speed step mode of the Lokmaus®2 in two ways. The first defines the used speed
steps valid for all locomotives – that means e. g. all locos run with 28 speed steps. The second defines
the speed steps different for each loco – e.g. loco 04 runs with 28 speed step, loco 17 with 128 and loco
98 only with 14. The factory default setting is 28 speed steps for all locomotives (this setting is restored
by the system-reset using C7). This setup is done by the menu C6 (see page 29).You can define the ge-
neral mode to 14 speed steps if there occur problems using the 28 speed steps mode.
The speed steps for the control of an individual locomotive can be changed in the running system very
easyly:
Select that loco and turn the knob to zero (middle position). Push the ‘P’ button and keep it pressed. Now
press additionally the arrow button ‘up’ or ‘down’. The display shows you the actual valid setting. One
bar means 14 speed steps, two bars 28 speed steps and three bars indicate 128 speed steps. If you
prees the button ‘up’ a second time the number of speed steps is raised, if you press ‘down’ it is lowered.
The new actual setting is shown in the display. The Lokmaus®2 memorizes this setting even at the end
of the session or in case of an interruption of the power supply (only inside the master Lokmaus®2!).
If you only want to control the setting of the speed steps of a loco the knob doesn’t have to be in the posi-
tion zero but then it can’t be changed.
IMPORTANT:
It is recommended that you also change the setting of the decoder accordingly to the set-
tings of the Lokmaus! Most decoders are set to the right speed step mode by a programmation of the
CV29 (see page 25). How to do this you find in the decoder’s or locomotive’s manual. If you don’t find in-
formation there please contact the decoder’s manufacturer. For the ROCO decoders you find a list of
features and settings at page 34.
If the settings of the Lokmaus®2 and the loco decoder don’t match the headlights do not work correctly-
or not at all or the loco doesn’t move. By a wrong setting the loco decoder
cannot be damaged!
IMPORTANT:
Remember that there are loco decoders that don’t support all speed step settings (e.g.
the old ROCO loco decoders only support 14 speed steps). At a setting to 128 speed steps such a loco
doesn’t run at all and if the speed mode is set to 28 steps the light flickers if the loco accelerates or dece-
lerates bat cannot be controlled by the Lokmaus®2.
