7. THE SECA 360° WIRELESS NETWORK

7.1 Introduction
This device is equipped with a wireless module. The
wireless module allows measured results to be trans-
mitted wirelessly for analysis and documentation. Data
can be transmitted to the following devices:
• seca wireless printer
• PC with seca USB wireless adapter

seca wireless groups The seca 360° wireless network operates with wire-
less groups. A wireless group is a virtual group of trans-
mitters and receivers. If you wish to operate several
transmitters and receivers of the same type, up to 3
wireless groups (0, 1, 2) can be set up.

66 •
 English

Setting up several wireless groups ensures the reliable

transmission of measured values with the correct
address when using more than one examination room
each with similar equipment.
The maximum distance between transmitters and
receivers is approx. 10 metres. This range may be
0 reduced under certain local conditions, e.g. thickness
and type of wall partitions.
1
The following combination of devices is possible for
each wireless group:
• 1 baby scale
• 1 personal scale
• 1 length measuring rod
• 1 seca wireless printer
• 1 PC with seca USB wireless adapter

Channels Within each wireless group, the devices communicate

with each other via three channels (C1, C2, C3). This
ensures reliable, troublefree data transmission.
When you set up a wireless group with this scale, the
device will suggest three channels guaranteeing opti-
mum data transmission. We recommend accepting the
channel numbers suggested.
C1
C2
C3 You can also select the channel numbers (0 to 99)
manually - for example if you want to set up more than
0 one wireless group.
The channels must be sufficiently far apart to ensure
trouble-free data transmission. We recommend a
spacing of at least 30 between channel numbers. Each
channel number may only be used for one channel.
Example configuration: channel numbers when setting
up 3 wireless groups within one surgery:
• wireless group 0: C1=_0, C2=30, C3=60
• wireless group 1: C1=10, C2=40, C3=70
• wireless group 2: C1=20, C2=50, C3=80

The seca 360° wireless network • 67

 Detecting devices If you wish to set up a wireless group with the scale, it
will search for other active devices from the seca 360°
wireless system. The devices detected are shown as
modules in the display on the scale (e.g. “MO 3”). The
meaning of the numbers is as follows:
• 1: personal scale
• 2: length measuring rod
• 3: wireless printer
• 4: PC with seca USB wireless adapter
• 7: baby scale
• 5, 6 and 8-12: reserved for system expansion
