Establishing a wireless connection

4 Establishing a wireless connection
WARNING
!
A maximum of 25 X-zone 5500 devices may be
connected on a wireless network as otherwise it is not
possible to ensure a reliable connection and alarm
forwarding.
CAUTION
!
FCC and IC: This device conforms to the requirements
in accordance with section 15 of the FCC regulations.
The following conditions must be observed for
operation:
The device must not be permitted to generate

harmful interference and
must absorb interference received, even though

this interference could result in operating faults.
Devices to which modifications not explicitly approved
by Dräger have been made are not permitted to be
operated by the user.
The internal/external aerials used with this mobile
transmitter must not be operated in the vicinity of or
together with other aerials or transmitters. Persons
must observe a minimum distance of 20 cm to the
aerials.
This device and the corresponding aerial must not be
permitted to be operated in the vicinity or together with
other aerials or transmitters.
NOTICE
i i
If the devices are in ON mode, they automatically
establish the wireless connection.
Up to 25 devices can be connected on a wireless network via
a wireless connection.
The typical radio range is up to 100 m in industrial
surroundings (environmental factors may affect the range).
The devices can be operated in a chain, star or ring topology.
It is possible to establish an open radio network or independent
radio networks. All devices
automatically connected.

4.1 Open wireless network (standard
configuration)
With an open wireless network, up to 25 X-zone 5500 devices
can be added to or removed from a wireless network number.
4.1.1 Independent radio networks
If independent radio networks are required, different network
numbers need to be assigned for the relevant radio networks
(see chapter on page 64).
Example:
Two independent radio networks each with three X-zone 5500
devices should be created. To do this, the Dräger CC-Vision
PC software should be used to set NET:001 with three Dräger
X-zone 5500 devices and NET:002 for three further X-zone
5500 devices.
4.1.2 Sub-networks:
1
3
1 Sub-network 1
2 Sub-network 2
3 E. g. steel wall, wall, HGV, etc.
Sub-networks are created via an unintentional division of the
open network into two or more radio networks. This can occur
if the user is running two activated X-zone 5500 (with the
same network number). This means that the devices have
permanently interconnected
(communication LED is lit in green). This means that the user
can no longer tell whether or not the wireless connection is
already set up with the devices already installed. To avoid sub-
networks, the X-zone 5500 devices should always be set up
and switched on in succession.
