LED Status

Constant blue - Normal operation

Lit in green - Programming mode

Flashing green - Decoder update

Flashing blue - STOP

Flashing red - Short circuit

Sniffer BUS

Driving and switching by using your existing legacy DCC digital command station (output voltage of 16 V or higher required).

 

At any time you can take over the loco with another throttle (or App) connected to the Z21®.

 

The direction of communication is always from the legacy command station → into the Z21®.

 

Booster BUS

10789 - Z21® -CDE Booster Adapter

10-15 Booster with CDE interface

10765 - Digital Booster 

Up to 3.2 A per booster
With five and over, you need the brake generator 10779

63320, 63340

Occupancy detector (2-rail tracks)

 

Following modules must be connected with LocoNet-B interface -> adapter necessary:

  • LocoNet Booster
  • BDL168, RX4
    Occupancy detector using transponding

 

Following modules are not compatible with full bridge power circuits and must not be connected to Z21® or Digitrax command stations:

  • MARCo
  • 63330, 63350
  • 68720, 68730

The L-BUS also permits connection via a multiZENTRALEpro to the multiMAUSpro

2. L-BUS enables the connection to multiMAUSpro via multiZENTRALEpro

 

Z21® FW V1.24 or higher with Z21® as LocoNet master

 

 

FW V1.09 (LocoNet slave)

 

 

Connect to EXT. 

The multiZENTRALEpro is the LocoNet slave and is powered by ther Z21® (12 VDC).

So do not use any power supply for the multiZENTRALEpro!

Connect the tracks with the LocoNet master.

FW V1.09 (LocoNet slave)

LocoNet master

The multiZENTRALEpro is the LocoNet slave and must be connected with the LocoNet master by using the white cable (136100) solely.

 

In this case the multiZENTRALEpro must be powered by its own AC adapter. 

4. With Z21® FW V1.22 or higher, the Z21® can be configured as LocoNet slave by using the Z21® Maintenance Tool 

Control the locos of your TWIN-CENTER/Intellibox by using the Z21® App, MULTIMAUS® etc...

This digital command station is the LocoNet master. In this use case, the Z21® is used as gateway between the TWIN-CENTER/Intellibox and all the Z21®-throttles or Z21® Apps.

It is now possible to control your layout not only with the TWIN-CENTER/Intellibox and its LocoNet throttles, but also with the Z21® App on the smartphone/tablet and MULTIMAUS® at the same time.

 

In order to avoid that the Z21® and the existing LocoNet master both provide the supply voltage at the same time, the supply voltage must be isolated on the L-BUS-connector (pin1 and pin6) at the Z21®.

In order to do so, please solely use the white "Z21® LocoNet Slave cable" with the spare part number 136100. 

Please ask your local dealer or find it online here

Using the wrong cable can damage the digital control unit!

R-BUS
