Establishing a wireless connection

Dräger X-zone 5500 49

4 Establishing a 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 within radio range are

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 65).

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 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 wireless connection

(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.

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
