The Android app is available for download from the Google Play Store. The app for iPhone and iPad can be found in the App Store.

In order to export your data there are some possibilities. In each case, both, your layout as well as your locomotive database, will be exported.

Import for Android:

In the old app under "Settings" first select the menu item "Export". Then tap on the layout you want to transfer to the new app and choose the option "SD-card". Therefore your layout is immediately saved on your device. 
Now open the new app and open the menu item "Layouts". Tap the plus icon at the bottom of the screen and select "Import from SD card". All layouts saved on your device now will be listed. Select the desired layout and choose a name. After tapping "Import" the layout will be transferred. 

Import for iOS:

In the old app under "Settings" first select the menu item "Export". Then tap on the layout you want to transfer to the new app and choose the option "Share (e. g.: new Z21 App)". 
A window will opens with a choice of apps. Tap on the app icon of the new Z21 app. The new app opens and you can choose a name for your imported layout. After setting a name, the layout can   be found immediately in the layout management of the new app. 

Import via e-mail (Android and iOS):

In the old app under "Settings" first select the menu item "Export". Then tap on the layout you want to transfer to the new app and choose the option "E-Mail". 
Your e-mail app opens with your layout attached. Send the e-mail (to yourself). Open the e-mail app on your device and tap the layout in the attachement of the sent e-mail. A window opens that suggests several apps to open the file. Select the new Z21 app. The app opens and you can choose a name for the imported layout. After tapping "Import" or "Import and select" the layout will be transferred. 

No, to operate the Z21 with a smartphone it is not necessary to have a SIM card. The connection between the smartphone/tablet PC and the Z21 is established via WLAN.

The setting option in the Z21 settings goes to the control centre via the stop button, whereas the app settings relate to the Stop button within the app. This means that the stop response can be set separately in both operating options.

Like the first smartphone, the second also communicates with the router: In the "Smartphone settings", "WLAN" section, you will find a list of the routers found, which should include the "Z21 ... wxyz" option. Tap to simply select this router and log on using the documents supplied with the Z21!

Yes, this is possible on a Windows system. The connection is established via the LAN port (network socket) on the computer.

Yes, you also have the option of operating the Z21 using a large selection of handheld controllers and various input devices. See also the overview diagrams in "All connections on the Z21", sections "X-BUS" and "LocoNet-BUS". For wireless controlling you can also use the Z21 WLANMAUS.

To configure the settings and for the firmware update, a connection to the app or to a PC is still required.

System components can be distributed and created in the app in multiple sections. Naturally, in comparison to a tablet, the smartphone is somewhat limited in terms of the smaller display. For large systems, PC control programs such as TrainController, iTrain, Rocrail or ModellStw. are recommended.

Most locomotive data is not stored in the Z21, but are stored in the app. In other words, it is not possible to access the same data using any control unit. On each device, the data must be recompiled (e.g. Z21 multiMAUS) or can be copied from app to app. Only the most important information on each locomotive/turnout is stored on the control centre for track signal generation, such as the format (DCC/Motorola) and the number of possible speed steps. For this reason, some setting options in the app are greyed out in offline mode.

Almost. When you have connected your new digital control centre and the WLAN router provided, you will need to register your smartphone on the Z21 and download the corresponding app via the internet. You can then place the first loco on the main track!

The X-BUS of the Z21 supports the connection of 31 devices.

LocoNet™ and the X-BUS ports on the front of the device are on the same power supply and are each only permitted to be loaded up to 500mA, i.e. in total 1000mA.

Due to the LocoNet™-T design without RAIL_SYNC signal, the operation of LocoNet™-Booster is not possible.

This is not possible as the Z21 means that restrictions such as the number of available characters in the locomotive name or function keys, are a thing of the past. In the new locomotive data records on the Z21 it is possible to create far more information (long names, function keys, image, etc.) than was possible with the Z21 multiMAUS. For this reason, the formats are not compatible.

It is not possible to use interface 10785 on the Z21. The PC connection to the Z21 is made via LAN.

Locomotives with FMZ decoders only will not be able to "understand" the track output signals in DCC or Motorola! Nevertheless, over a number of years, FLEISCHMANN has recently "added two-language" decoders FMZ/DCC to its range: If you have these types of decoder versions, the locomotives can be controlled using DCC !

The apps are designed for operation with the Z21.

No, all you need is a standard, digital model system such as FLEISCHMANN or ROCO.

Due to the vast number of s88 building kits and various "craft projects," galvanic isolation from the LocoNet™ bus and track cannot be guaranteed. For this reason, as a precaution we need to state a categoric "No" in terms of the s88 adapter as well.

The track voltage is only valid during the programming process. 

Short circuits are always possible when operating a model railway. For safety reasons, and to avoid damage, the Z21 detects both short circuits and overloads, and cuts out at currents over 3 A. It is therefore better to limit the number of amperes per booster section.

The Z21 can control up to 29 locomotive functions depending on the control device: Light (F0) and F1 to F28.

The upper limit is 100 locomotives in firmware version V1.24. The corresponding prioritisation of the drive commands ensures a good response from the locomotives.

Yes, the Z21 can produce the RailCom®cut-out . However, the RailCom cut-out can also be deactivated in the app settings or in the Z21 Maintenance Tool should any problems arise with older decoders or boosters.

The Z21 LAN protocol has been available since the start of 2013 and can be found in the Downloads area. No licence is required to use it.

Dimensions of the Z21: 207mm x 146mm x 37mm

Dimensions of the WLAN router: 174mm x 144mm x 30mm

No, because some older Zimo decoders react sensitively to an interruption in the programming process. For this reason, the decoder update has been limited to the more recent models of decoder that are available from Roco and that handle updates reliably.
The decoder update is carried out using the Z21 Maintenance Tool. 

The "small" power pack is more than adequate as the systems are not generally operated continuously at 3 A. In addition, turnouts and other components are switched, leading to short-term current peaks. And these accessory items will certainly consume 0.5 A taken across the market. At 2.6 A of the power pack, the storage capacitors in the Z21 offers the full reserve for this, including across an extended period. In addition, the specified values of the power supply should be regarded "conservatively."

No, for various reasons the Z21 will only be available in combination with the WLAN router. A few of these reasons are outlined below:

• The majority of our customers are not necessarily experienced with WLANs, and we want to make the product easy to set up using Plug&Play.
• Only a small number of customers have a LAN port for their home router located close to their model railway.
• Many customers have set up their model railway outside the secure WLAN range of their home router, meaning the integrated router ensures secure WLAN reception directly on the system. 

In contrast, the z21start is sold without a router in the starter sets. The corresponding, pre-configured WLAN router can be purchased separately as WLAN Package with activation code (10814). 

On the rear of the TP-Link device on the far left is a recessed Reset button that can be pressed using the centre of a ballpoint pen. Instructions on how to use the router again can be found in the Z21 Router Configuration Guide in the downloads area.

All the information on changing the password of the Z21 WLAN can be found in the Z21 Router Configuration Guide in the downloads area.
