2.1 Connection of Additional Control Devices
You will probably prefer to control your Z21 Digital System from your smartphone or tablet PC. But if you want to share control with others or do not have your smartphone at hand, you can also connect your current multiMAUS or local mouse control devices to the X Bus sockets of the Z21 Digital Centre.
Each of these control devices can interface with all locos and digital components. This allows controlling at any time locos controlled by other devices by selecting any function of the corresponding loco or the loco controller from your Z21 mobile app.
2.2 Compatibility with ROCO and Fleischmann Components
The Z21 Digital Centre can be connected without problem to all ROCO and Fleischmann digital devices, based on the ROCONet or the X Bus protocol. These include:
▶ multiMAUS, Lokmaus 2 and Lokmaus R3 (Art. No. 10760, 10790, 10860 and 10792)
▶ Keyboard (Art. No. 10770) and RouteControl (Art. No. 10772)
▶ ROCO booster (not RailCom© compatible, Art. No. 10762 and 10765)
▶ For further information on compatibility, see online www.Z21.eu.
2.3 Power Supply for the Z21 Digital Centre
As a power supply for the Z21 Digital Centre, please use exclusively the supplied AC adaptor (Art. No. 10851). Positively do not use a wound-core transformer!
With the Z21 Digital System, you can modify the voltage applied to your system at any time by software.
For this purpose, change to the menu “Z21 Settings” in the Z21 mobile app. Always make sure to stay in 11 to 23 V range. Typical voltage ranges are from 14 to 18 V (for the gauges H0 and TT) and approx.12 V (for the gauge N).
Maksimal kirish hajmitage for the Z21 Digital System is 24 V. The maximum track voltage is always 1 V below the input voltage.
The Z21 Digital Centre is designed for loads of up to 3.2 A. If frequent power cuts occur in the system due to overloads, please install a booster (see Page 46).
Eslatma: To find out the current power consumption of your system, check the menu point “Power Centre” in the “Z21 Settings” menu of the Z21 mobile app.
Ogohlantirish: Positively do not connect the Z21 Digital Centre to ROCO amplifiers Art. Nos. 10761 and 10764! Use these components only on electrically separate layout parts connected only by transition tracks.
Eslatma: How to compute the power consumption of an H0 system:
▶ Stationary locos with light: approx. 100 mA
▶ Travelling locos depending on size and load: 300 – 600 mA
▶ Illuminated coaches: approx. 30 mA per minibulb (expect considerable fluctuations!)
▶ Digital coupling or smoke generator: approx. 100 mA
▶ Digital switch drive or switch decoder: approx. 500 mA as reserve
Eslatma: Easy programming of your loco decoder
▶ Place loco onto programming track
▶ Start the Z21 mobile app
▶ Switch to programming mode
▶ Enter the new parameters
▶ Ready!
2.4 Operation of Digital Locomotives
The Z21 Digital System is suitable for the control of all locomotives using ROCO loco decoders or any DCC-compatible decoders. Your Z21 Digital System can administer up to 9,999 loco decoders. The preconfi guration by the factory of all ROCO and Fleischmann locos is decoder address 3. If you use several locos on your system simultaneously, you need to assign a separate decoder address to each one.
With the Z21 Digital System, this is very simple: put the locomotive as the only loco onto the programming track. Select the locomotive on Z21 mobile app and give it a name and decoder address not yet assigned in the programming mode. That’s it!
All magnetic items (switches, decoupling tracks, signal decoders) equipped with a digital decoder can be programmed and controlled with the Z21 mobile app just as easily.
2.5 Upgrading of Analogue Locomotives
Locomotives and components without decoder cannot be used in the Z21 Digital System.
Due to the entirely different voltage supply, the use of a non-decoder loco results in a highly irritating high-frequency noise. In addition, there is a risk that the motors will be damaged.
However, many analogue models can be refitted with loco decoders and so made suitable for use on your Z21 layout. With locomotives with a free slot and an operational digital interface, this is very simple and easy because as a rule, the decoder merely needs to be plugged into a free socket.
2.6 Resetting the Z21 Digital Centre
If your digital system no longer operates flawlessly, please reset your Z21 Digital Centre to the factory setting as follows:
▶ Press the stop key on the front of the unit.
▶ Keep the key depressed for 5 seconds. The LED light starts flashing in purple.
This shows the Z21 Digital Centre has been reset to the factory setting. If the digital system still does not operate flawlessly, contact your dealer.
2.7 Update of Z21 Digital Centre
When your smartphone or tablet PC is connected to the Internet, you can search for apps and the Z21 firmware in the “Updates” section of software updates at the AppStore and Google Play.
Eslatma: You can have your locomotives converted in a professional workshop.
For a list of recommended suppliers, see www.ROCO.cc/en/service-partner.
Ogohlantirish: Locomotives and components without decoder cannot be used on the Z21 Digital System.
Eslatma: The firmware of your Zimo loco decoder can be updated very conveniently via the programming track. For this purpose, simply drive the respective locomotive to the programming track. In the Z21 mobile app, switch to programming mode and select the menu item “Decoder Update.
Ogohlantirish: Only one loco can be read out and/or programmed at the same time.
Eslatma: When setting the length of the programming track, take the longer tenders of steam locomotives into account!
2.8 Programming and Read-Out Track
As long as you wish to program one single loco decoder, you can program it directly on the main track. For this purpose, simply mark the loco in the Z21 mobile app, switch to programming mode and change the desired parameters.
If you want to read the decoder settings or do not know the decoder adress anymore, we recommend the use of a separate programming track.
You can use any partial section of your layout as a programming track – simply isolate it on both ends with insulated rail connectors (Art. Nos. 42611, 61192, 6433 or 9403) or separator rails and then connect it to a power supply element (Art. No. 61190) at the “Prog Track” socket of the Digital Centre.
To program a loco, simply drive it to the corresponding track section. Then change your Z21 mobile app to programming mode (for details, see www.z21.eu). The Z21 Digital Centre now switches the track automatically into programming and read mode.
You can now read the decoder data of the locomotive in the Z21 mobile app via RailCom© and set new CV values for the locomotive. For details, also see www.z21.eu.
2.9 Feedback at Programming and Main Track
If power consumption exceeds 2.5 A, the section is overloaded and must be divided.
Ogohlantirish: The booster and the Z21 Digital Centre must not be operated with the same transformer or AC adaptor!
Make sure that at the change-over turnouts, the tracks have the same polarity to avoid shortcircuits when driving over the separating turnouts. Make sure that powered tracks have no capacitors.
Driving with a Booster
When your system turns off frequently without a loco or coach having derailed or in the absence of a wiring error, as a rule this suggests an overload due too many power consumers. In this case, a booster (Art. No. 10765) which supplies extra power to the layout via an extra transformer (Art. No. 10718, 10725 or 10850) will help.
O'rnatish oddiy:
▶ Subdivide your system into two supply sections having approximately the same power consumption. Separate the tracks on both sides using insulated rail connectors (Art. No. 42611, 61192, 6433 or 9403) or separator tracks.
▶ Attach a power supply element to the new supply section (e.g. geoLine Art. No. 61190) or another separator track and connect it to the “Track Out” socket of the booster.
▶ Now connect the booster to its transformer.
▶ Connect the “Booster In” socket on the booster with the “B Bus” socket of the Z21 Digital Centre. Use the dedicated cable supplied with the booster for this purpose. A detailed cabling diagram is found on Page 47.
You can connect up to three more boosters to the “Booster Out” socket of the booster when necessary. If more than four boosters are needed for your layout, a brake generator (Art. No. 10779) must be connected in place of the fourth booster. Up to four more boosters can then be connected to the “Booster Out” socket.
Note: To make sure that the loop module responds quickly enough, the sensitivity must be set prior to operation using the potentiometer visible at the side. Observe operating instructions.
Loops in Digital Operation
Every DC railway enthusiast knows the following problem: if after a loop, the left rail profi le meets the right one, a shortcircuit occurs without the appropriate wiring.
With our loop modules (Art. No. 10767 or 10769), this switching problem in digital operation is elegantly taken care of: simply separate the loop on both sides on two poles and insulate the rest using insulated connectors (Art. No. 42611, 61192, 6433 or 9403) electrically from the remainder of the layout (see Page 49). The separated layout portion within the loop must be longer than the longest train which is to drive through the loop. The power to the loop is supplied by the loop module which is connected either to the track outside the loop or to the Z21 Digital Centre.
And this is how the loop module works: as soon as a train enters the loop regardless of the direction, shortcircuit detection occurs in the module. The polarity in the loop is automatically changed before the shortcircuit detection of the Digital Centre is aware of it or before the trains slows down. The polarity reversal is repeated when the train leaves the loop. Thus, the train can pass through a loop without stopping or operator aralashuv.
