The Master-And-Slave Principle; Combination Of Digital And Non-Digital System Parts - Roco multiMAUS Manuel

The master-and-slave principle

If a multiMAUS is plugged into the master connection on the amplifier, it automatically becomes the master. This
multiMAUS is then the higher order instance – the central control unit – in the digital system. In order to be able to
use all functions without restrictions, you should only connect one multiMAUS to this connection on the amplifier.
A Lokmaus 2 used as a master severely limits the options for a multiMAUS used as a slave.
Only one device at a time can be connected to the master connection of the amplifier!
All the Lokmaus devices connected to the slave socket on the amplifier or any other devices automatically have the
status of slave. If the master Lokmaus is removed, an immediate emergency stop is triggered.
If a locomotive is already controlled by another mouse connected to the system, the locomotive symbol flashes.
The locomotive can still be taken over by another mouse at any time if either a function is selected or the controller
is activated. However, the speed and direction of travel of the locomotive remain unchanged until the controller on
the mouse taking over the control is activated. The functions activated in the locomotive are displayed by all mice.

Combination of digital and non-digital system parts

All ROCO digital locomotives can be driven on both digital and "normal" direct current systems without any com-
plications. The locomotive decoder automatically detects the type of system it is on. It is therefore simple to use
both types of systems together so that you can still use non-digital locomotives on the direct current section of the
system.
Separator module 10768
The digital and analogue sections of your systems need to be insulated on both sides at the change-over turnout so
that there is no electrical connection between the two systems. For this purpose you can use either the insulating
track connectors 42611, 61192 or saw the track profiles.
The wheels of the vehicles would however still cause a short circuit between the digital and normal current which
could in turn destroy the booster. To prevent this, install the separator module in the supply line of the normal drive
transformer to the feeder track. It immediately breaks the connection between the normal transformer and the
feeder track when the separating point between the systems is jumpered. Thus the short circuit detection does not
switch off the multiMAUS and the train can pass the separating point.
At the change-over from digital to direct current operation the locomotive decoder immediately detects the oper-
ating mode and sets the speed of the locomotive to the respective voltage. The decoder also checks the polarity
of the direct current during the change-over. If it does not match the direction of travel, the train stops with the
programmed braking delay. If the train is to travel on further, you must first set the transformer controller to zero
and start the train again.
The decoder acts in the same way when making the change-over in the opposite direction. It retrieves the digital
information in the digital circuit immediately and continues to travel accordingly. The locomotive decoder also
checks the direction of travel in this case and stops the train with the programmed braking delay if it does not match
the actual direction of the current. You now have to change the direction of the train with the multiMAUS in order
for it to travel any further.
A change-over section of track
The simple switching method using the 10768 separator module described above has one minor disadvantage if
there are several trains in the conventional section of the system:
The entire conventional area is supplied with digital current when the train jumps the separating point. This causes
all normal locomotives to stop and all digital locomotives to retrieve their digital information and behave accord-
ingly at that moment.
You can prevent this unwanted effect using a change-over section of track ( see fig. 4 on page 63). It needs to be
as long as the longest train. It is double-pole insulated on both sides. The change-over section of track is now
monitored and changed accordingly by the separator module when the train passes over the separating point. Drive
operation on the rest of the system remains unaffected.
