Connecting Several Controllers; Combination Of Digital And Non-Digital System Parts; A Change-Over Section Of Track - Roco multiZENTRALEPRO Manuel

5.3 Connecting Several Controllers

It is possible to connect several Lokmaus control units to the "RocoNet" ports of the multiZENTRALE (see
PRO
Chapter 5.1.1).
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.

5.4 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 compli-
cations. 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.
5.4.1 Separator module ROCO 10768 (discontinued by the factory as of 2007)
Digital- und Analogteil Ihrer Anlage müssen Sie an den Übergangsstellen beidseitig isolieren, damit es zwischen den
beiden Systemen keine elektrische Verbindung gibt. Use insulating track joiners ROCO 42611, 61192, Fleischmann
6433 (H0), 9403 (N).
However, the wheels of the vehicles would still cause a short circuit between the digital and the regular traction
current, which could destroy the multiZENTRALE . To prevent this, install the separator module in the supply line
PRO
of the normal drive transformer to the feeder track. It immediately breaks the connection between the normal trans-
former and the feeder track when the separating point between the systems is jumpered. The short circuit detection
therefore does not switch off the multiZENTRALE 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 PRO in order
for it to travel any further.

5.4.2 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. 5 on page 92). 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.
