4.2 Mounting the antennas
Wi-Fi /Bluetooth planar antenna for the CR3131 device: art� no� EC2118
►When mounting the antennas in vehicles avoid the vicinity of fuel tanks,
vessels with explosives or insufficiently screened electronic components (→ 2
Safety instructions)�
►Position the antennas so that a permanent distance of min� 0�2 m from people
is ensured during operation�
►Do not install the antennas in closed metal constructions such as the driver's
cab�
►Please observe the notes of the antenna manufacturer�
Stable data transmission requires a good antenna signal� In case of
problems change the position of the antennas or the mobile equipment if
necessary�
A loosely tightened antenna connector also causes signal loss�

7.3 Wi-Fi interface
The use as Wi-Fi interface allows wireless transfer of CAN data to other Wi-Fi
capable devices such as PCs, smartphones or tablets on which CAN data can be
recorded and evaluated�
The device can be integrated in the existing network infrastructure (infrastructure
mode)� In the mini access point mode the device can assume the function of
a Wi-Fi router and provide a wireless network for other Wi-Fi capable devices
in the infrastructure mode� The network parameters can then be provided by
CANwireless via DHCP server�
Data is exchanged bidirectionally as soon as the software has established a
connection to the device�
The ifm maintenance tool is used for the configuration via the CAN interface�
7.4 Wi-Fi configuration
The use as Wi-Fi bridge ensures wireless transfer of CAN data between two CAN
bus systems� In this case, two CANwireless devices replace the CAN cable�
To use two devices as Wi-Fi bridge, one device must be configured as slave and
one device as master� The device is configured as slave by the factory�
The ifm maintenance tool can be used for the configuration�
7.4.1 Wi-Fi mini access point mode
Configuration device 1 (master):
In the Wi-Fi bridge mode some of the data entered here is also required for
the configuration of device 2 (slave)�
►Deactivate Bluetooth under "Bluetooth settings"�
►Activate Wi-Fi under "WLAN settings"�
►Select "Mini AP" under "Operating mode"�
►Enter a network name under "SSID"�
►Select the Wi-Fi encryption under "Authentication type" which complies with the
required safety criteria and enter the respective data�

►Transfer the configuration to device 2�
The connection between a configured master and slave device is made
automatically after power-on� Data is exchanged bidirectionally as soon as the
connection between the two devices has been established�
7.5 Bluetooth interface
The use as Bluetooth interface allows wireless transfer of CAN data to other
Bluetooth capable devices such as PCs, smartphones or tablets on which CAN
data can be recorded and evaluated� Data is exchanged bidirectionally as soon as
the software has established a connection to the device�
The ifm maintenance tool is used for the configuration via the CAN interface�
