3 Configuration
There are different ways of configuring the EPAs for operation:
Easy Config (“MODE” button)
Typical operating modes, such as direct connection of two EPAs as a “wireless Ethernet ca-
ble”, can be directly activated via the “MODE” button on the EPA without the need for a PC.
A detailed description can be found in Section 3.1 “Easy Config (“MODE” button)” on
page 3-1.
Web-based management (WBM)
To use all the important options, the device has a web-based management using a web
browser. This means that the current operating state can simply be displayed without the
use of special software or the device can be configured.
For parameter description, please refer to Section “Web-based management” on page 4-1.
AT commands
All the EPA parameters can be modified or transmitted to the EPA in an automated manner,
for example from a program of a controller. For development or testing purposes, AT com-
mands can also be transmitted to the EPA via the web-based management using the web
browser.
The AT command reference can be found, for example, in the web-based management ap-
plication under the “Help” menu item.
3.1 Easy Config (“MODE” button)

3.1.1 Using the “MODE” button
1. Switch on the device and wait for the Link Quality LEDs to light up and go out again.
Then press and release the “MODE” button.
Step 1 must be carried out within 5 seconds after switching on the device.
2. Press the “MODE” button repeatedly to cycle through the Easy Config modes until the
desired mode is indicated by the A-B-C-D LEDs.
Mode 2 is the first mode. Only suitable LED combinations are shown.
3. Press and hold the “MODE” button for at least two seconds, then release the button.
This will confirm the selected mode and restart the device.
Step 3 must be carried out within 20 seconds after step 2. Otherwise the device will exit
Easy Config setup and return to the previous settings.
3.1.2 Easy Config modes
Modes 5 ... 8 are used for defining the operating mode of the network (WLAN/Bluetooth,
with or without optimization for PROFINET operation). Set the device which will later act as
an Access Point/NAP to the desired mode.
Configure the clients for mode 4. The Access Point or NAP then configures the devices in
mode 4, matching the selected operating mode. As soon as a device is configured as a cli-
ent, the device is restarted.

Configuration
108452_en_02 PHOENIX CONTACT 3-17
The Access Point scans for configurable devices for 120 s (the scan can be canceled by
switching it off and on). The device is then also restarted. The connection is established au-
tomatically.
Figure 3-2 “Easy Config” web page
The Access Point retains the configured IP address. The clients/PANU are assigned the IP
addresses in ascending order or - if not possible - in descending order.
Example: Based on the factory settings, the AP/NAP IP address is 192.168.0.254. The IP
addresses 192.168.0.253, 252, … are then assigned to the clients.
If the AP has previously been configured to 192.168.3.50, it will retain this address.
192.168.3.51, 52, … are then assigned to the clients/PANU.
A WLAN connection is established on channel 6. The channel can also be changed subse-
quently using the Access Point web interface.
The connection is layer 2-transparent and thus also suitable for PROFINET.
If several radio sets are used within a common backbone network, configuration via Easy
Config may lead to the double assignment of IP addresses. This is due to the fact that
each radio set starts with 192.168.0.254. In this case, assign unique addresses before-
hand or subsequently using the web interface.
For functionally safe communication, refer to the information in Section “Safety-related
communication (PROFISafe/SafetyBridge)” on page 4-15.

4 Web-based management
4.1 General
The web-based management is accessed by pointing a web browser to the EPA IP address.
The default IP address is 192.168.0.254. The computer accessing the web-based manage-
ment must be in the same IP subnet as the wireless bridge.
Figure 4-1 “System Overview” web page
The web-based management is designed for the current versions of Internet Explorer,
Chrome, Firefox and Safari. Other browsers may not support the full functionality of the
web-based management.
All changes are activated using the “Safe and Reboot” button. The button will only be ac-
tive if parameters have been changed. This also applies to changes made to the device
on other web pages during this session. Selecting another menu item within the configu-
ration pages does not discard the changes that have been made to the configuration.
However, unsaved changes will be lost when closing the connection without pressing the
“Safe and Reboot” button.
Using the “Cancel All Changes” button, all settings that have not yet been saved via “Safe
and Reboot” will be discarded.
