9 Chapter 2 2. General Concepts 2.1 Configuration Methods The Wireless Bridge supports four main methods for setting and configuring the module: Smart mode - Use the buttons and LED s on the Wireless Bridge to automatically set up the most common use cases. Web interface - An online WEB interface with the most common settings for the Wireless Bridge. AT commands - Connect to the Wireless Bridge over Ethernet using TCP, or directly on Layer 2 and use a terminal such as Hyperterminal to issue AT commands. This method is mainly for more advanced settings and use cases and is not described in this document. All commands available in the web interface and much more are supported throught the use of AT commands. The SNMP protocol - This will not be used or described in this document. 2.2 Using the SMART Configuration Mode If the Mode button is pressed within 5 seconds from power up, the Wireless Bridge will enter SMART configuration mode. The LED s above the button (A, B, C, and D) will show the mode currently selected. When the required mode is selected, it must be confirmed by holding in the Mode button for two seconds. This will cause the LED s to start flashing during the operation of the selected mode.

10 General Concepts 6 There are currently 9 different modes available: Mode Description LEDs A B C D 1 Configuration mode A 2 Reset to factory defaults. This will reset the entire configuration to B factory defaults. 3 Reset IP settings to factory defaults. This will only reset the IP settings A + B to factory defaults. 4 Wait for Automatic configuration (LED C ). C 5 Initiate Automatic configuration (LED A and C ). A + C 6 Initiate Automatic configuration with Profinet optimizations (LED B and C ). 7 Initiate Automatic configuration to a connectblue WNP (Wireless Network Platform) (LED A, B, and C ). 8 Initiate Automatic configuration with EDR (LED D ). D B + C A + B + C 9 Initiate Automatic configuration with Profinet optimizations and A + D EDR (LED A and LED D ) 10 Reserved for future use. B + D 11 Reserved for future use. A + B + D 12 Reserved for future use. C + D 13 Reserved for future use. A + C + D 14 Reserved for future use. B + C + D 15 Reserved for future use. A + B + C + D Configuration mode can be used to easily access the Ethernet Port Adapter (EPA) if the PC is using DHCP, without having to change the PC s IP settings. This mode should only be used when the PC is connected directly to the EPA, and not if the EPA is connected to a network using a DHCP server. Enable this mode, then connect the Ethernet cable to the computer. The EPA will then use the factory IP settings ( / ) and the configuration interfaces will be enabled (if disabled earlier). The DHCP server will stay enabled until the EPA is rebooted Using the WEB Configuration Interface By default, the EPA has the following static IP settings; IP address: Sub net mask: Default gateway: To access the EPA via the Web-based configuration interface, the computer must be set up in the same network, e.g. IP address: and sub net mask: Open a web browser and enter in the address bar. The most common configuration parameters needed to setup a connection are listed here. If the Wireless Bridge is in factory default, there is no need to log in before configuring the device.

11 General Concepts 7 An example of the web interface is shown below: Reset to Factory Defaults It is possible to reset to factory settings in 3 different ways. Enter and confirm SMART mode 2 Issue AT&F Hold in the mode button while the Wireless Bridge is starting. Note: Check that the Ethernet cable is disconnected, and that any firmware update program has been stopped.

12 Chapter 3 3. Bluetooth Profiles and the Wireless Bridge For Ethernet access using Bluetooth, the Bluetooth Personal Area Network (PAN) profile is used. In this profile, there are two important roles: PANU - Pan User Role. This is the standard client role used when a Bluetooth device is connected to an Ethernet device. Two PANU devices may connect to each other. Several PANU devices may connect to a Bluetooth Access Point supporting the NAP role (see below). NAP - Network Access Point Role. This is a device connected to a network, supporting multiple devices using the PANU role. A maximum of seven simultaneous connections are possible (due to limitations of Bluetooth). NAP is the role normally used by a Bluetooth Access Point. Note: The Wireless Bridge only supports one connection in the NAP role.

13 Chapter 4 4. Supported Use Cases 4.1 Two Wireless Bridges Connected as an Ethernet Bridge Overview This use case describes two Wireless bridges connected as bridge between tow Ethernet segments. Both Wireless Bridges support several Ethernet devices and transfer data between the two Ethernet segments Set Up the Use Case. This use case can be set up using the SMART button. This is used to transfer data between two Ethernet segments: 1.
