This section explains the context of the CEREC Radio Device by
describing the main function and identifying the system components.
5.1 CEREC system
The CEREC system consists of a mobile acquisition unit and a stationary
milling unit.
The acquisition unit generates the restoration data which is transmitted to
the milling unit.
The acquisition unit establishes a TCP/IP connection with the milling unit
for the data transmission.
An Ethernet infrastructure is required for this.
This can be implemented by standard, wired LAN infrastructure, a WLAN,
or the CEREC Radio Device system as described in this document.

5.3 Main function
The objective of the CEREC Radio Device is to obtain a reliable, wireless
data connection between a stationary milling unit and a mobile acquisition
unit. The wireless network that is created can then be used to transmit
time-dependent data.
For the acquisition units and milling units there is no difference between
the CEREC Radio Device and a local wired network (LAN); the
connection is completely transparent.

5.4 Network unit
The CEREC Radio Device enables the setting up of a range of wireless
network units that together create a wireless network. The number of
network units in one network is limited to three. These network units
implement a proprietary Sirona protocol specially developed to comply
with time-dependent transmission requirements for CEREC Radio
Device applications.
The basic functionality of a network unit is to convert incoming Ethernet
data into a number of packages for wireless data transmission and to
forward these to one or more neighboring network units (and vice versa).
This functionality is comparable to an Ethernet network switch. As such,
this network can be used as a wireless network (WLAN) and is completely
transparent for Ethernet communication.
Using this functionality, a link between two network units can support the
data communication between an acquisition unit and milling unit.
A network unit can have three different roles:
● Directly connected to a milling unit using a network cable and
powered by the supplied mains adapter.
● Built into an acquisition unit where it is directly connected to the
integrated PC via a network cable and powered via the USB 3.0
connection of the PC.
● Connected to LAN infrastructure, i.e. to a hub or switch and powered
through the mains adapter.

båÖäáëÜ
A schematic representation of a network unit is shown below.
As can be seen in the image, the network unit has four connection points:
●Antenna
The network unit has two antennas that are screwed on during
production. These antennas must not be removed or replaced with
different antennas.
●Micro-B USB
For power the network unit has a standard Micro-B USB port. A
standard 5V power adapter supplied in the package can be plugged
into this port. However, any standard USB 3.0 connection can be
used to power the network unit. The network unit integrated in the
CEREC mobile acquisition unit is powered through this port.
●RJ-45
The network unit has an RJ45 interface to which the standard
network cable (CAT5) can be connected. The network unit can be
connected to any other Ethernet communication device through this
interface. To establish a connection with the LAN infrastructure, you
can alternatively connect it to an Ethernet connection component
such as a hub or switch.

6Networking
This section describes the network function of the CEREC Radio Device.
Below you will find a list of the sections:
● CEREC Radio Device network overview
● Creating a network
● Network creation failures
● Extending the network
● Reset to factory defaults
● Network unit states
● Radio characteristics
6.1 CEREC Radio Device network overview
The network units in the CEREC Radio Device network create a so-called
peer-to-peer mesh network. This means that there is not a master or
slave as with Bluetooth, nor a central controlling access point for the
control as with WLANs.
As such there is no distinction between a network unit connected to a
milling unit, one that is built into an acquisition unit, or one that is
connected to LAN infrastructure: any network unit belonging to the same
network (see “Creating a network [ → 18]”) can communicate with all other
network units in this network that are in range. This is also applicable
when they are out of range of all other network units, making establishing
network connections very flexible.
The wireless network operates in the 2.4GHz band which is available
worldwide for license-free operation. It therefore needs to be able to
communicate with other wireless networks such as WLAN or Bluetooth
networks. The network accomplishes this by avoiding congested
channels wherever possible. However, the network is not completely
immune to interferences caused by other wireless technologies. The
result of these interferences can be a reduced range and drops in
performance. The network technology therefore offers several easy
mechanisms with which a network can be extended to achieve better
coverage (see “Extending the network [ → 20]”).
The network can also easily be extended and the coverage increased,
using LAN cables or even an existing LAN infrastructure (see “Increasing
the range [ → 30]”).
6.2 Creating a network
Network units that come out of the box have never been part of a network.
To allow for several networks of different owners to operate side-by-side
or in the same area, new network units must first create a network. This
is described in the following section.

Sirona Dental Systems GmbH 6Networking
Operating Instructions CEREC Radio Device 6.3Network creation failures
båÖäáëÜ
6.2.1 Creation
To create a new network with a number of new network units the following
steps must be completed:
1. Bring all network units together in one room.
2. Power-up all network units within one minute.
3. Wait approximately one minute after the last network unit was
powered-up.
4. Check that all the network units are connected, indicated by the green
LED (see “LED displays [ → 11]”).
When completed, all network units will belong to a single network, which
can be operated as an independent network, and can communicate with
each other. The network created in this way is unique worldwide. See
“Network creation failures [ → 19]” should a problem arise.
6.2.2 Isolated network unit
A unique network is only created when two or more network units are
present. In case of an isolated network unit, no network is created until
another network unit is within range.
6.2.3 Permanent network
When a network unit has been added to a network, the network ID is
stored permanently. When network units are switched off and back on
again, they re-establish a connection with the network.
6.2.4 Installation
After the network has been set up, the network units can be switched off
and placed at their designated locations (to connect them to the milling
units, for example).
Since the network creation is permanent, the network units remain part of
the network even after switching off and switching back on again. This
applies even if they are placed outside of range of other network units, for
example in case of an isolated milling unit in a separate room.
6.2.5 Maximum size
A network can comprise up to three network units. Larger networks are
not possible.
6.3 Network creation failures
The following section describes potential issues which could arise when
creating a new network and offers solutions for each scenario.
6.3.1 Isolated network unit
When a single network unit is powered-up too late, it may not be part of
the network. This can be identified if the LED does not turn green.
This situation is the same as when a new network unit is added to an
existing network. This is described in “Extending the network [ → 20]”.

6.4Extending the network Operating Instructions CEREC Radio Device
6.3.2 Multiple networks created
When more than one network unit is powered-up too late, these network
units could form their own network.
Initially this will not be clear because all network units will indicate that
connections to other network units have been established with a green
LED (see “LED displays [ → 11]”).
One way of checking this is to connect a PC with a fixed IP address to
each network unit and try to ping the PCs from another PC. Another way
is to switch-off all but one network unit. Then complete the following steps
for each additional network unit:
1. Switch a network unit on.
2. Wait until the orange LED goes out.
3. The LED lights up green and the network unit belongs to the network.
4. Go to the next network unit.
If a network unit is not connected, the orange LED lights up constantly.
When this occurs the network unit must be reset to factory defaults (see
“Resetting to factory defaults [ → 22]”) and then added to the network by
switching one of the other network units off and back on again (see
“Extending the network [ → 20]”).
6.4 Extending the network
Additional new network units can be added to an existing network. This
section explains how this is done.
6.4.1 Adding a new network unit
New network units can be added to an existing network. However, to
prevent any network unit from becoming part of the network, the user
must complete four simple but specific steps:
1. Place the new network units next to a network unit belonging to the
network.
2. Switch-on the new network units.
3. Within one minute, switch the existing network unit off and then back
on again.
4. After one minute the new network units will become part of the
network.
