Section 1 Introduction The AP (IEEE 802.11 HR, 11 Mbps WLAN Access Point) is a long-range, high performance LAN product, which provides Access Point services to a 2,4 GHz RF network and bridges to an Ethernet backbone. The design of this product is based on AT76C510 (bridge-on-a-chip) module, a highly integrated ASIC designed to combine legacy LANs with wireless LANs. AT76C510 performs all the necessary inter-networking and bridging functions.
Introduction – Glueless connection to Intersil PRISMI, PRISMII Direct Sequence Spread Spectrum (DSSS) radio chip set. Able to communicate also with other DSSS radios – Supports 11, 5.
Section 2 The AP Development Board Figure 2-1 shows the Access Point development board. The basic features of this board are outlined below: • Interfaces directly to 10/100 IEEE 802.3 Ethernet networks. • Supports IEEE 802.11b (High data rate) WLAN functions. • Firmware is stored in a flash memory and can be upgraded remotely. • Single 5V 1Amp universal power supply. • Configurable through Ethernet and USB ports. • Power and wireless activity LED indicators.

Section 3 Setting the IP Address of the Access Point The first step in using the AP is to set its IP Address. This procedure can be done either through the Ethernet port by using a combination of Arp/Ping commands and the SNMP Manager, or the USB port by using the DFU utility. 3.1 Using the Ethernet Port In order to set the Access Point IP address you need to know the Access Point MAC address.
Setting the IP Address of the Access Point press OK. Type the IP address in the “IP Configuration” window under the “Setup” menu, “Bridge” submenu. In order to save the configuration select “Download Changes” under the “File” menu. See also the paragraph “Using the SNMP Manager” in the section “Access Point Configuration”. 3.2 Using the USB Port Note: This procedure requires the use of the DFU Configuration Utility which can be used only through the USB port.

Section 4 Access Point Configuration The AP configuration can be done either through the Ethernet port by using the SNMP Manager application, or the USB port by using the DFU Utility. 4.1 Using the Ethernet Port In order to configure the AP through the Ethernet port, you must first install the SNMP Manager application, which is a powerful and reliable tool used for the remote configuration of the Access Point through the Ethernet port. 4.1.
Access Point Configuration Figure 4-1. Connecting to the AP using the SNMP Manager In case of a successful connection to the Access Point, the following window appears (Figure 4-2). Press “OK”. Figure 4-2. Agent found In case of an unsuccessful connection you receive the following message (Figure 4-3): Figure 4-3. Agent not found If the above error message appears, you need to check if the AP has the desired IP Address and is connected to the network.
Access Point Configuration When the connection has successfully been established, you get a message in the right bottom corner indicating “All values retrieved”. If the message “Not all values retrieved” appears, you need to repeat the above procedure (Figure 4-1). As soon as the connection has been established, you are now able to start viewing or setting the Access Point parameters.
Access Point Configuration Figure 4-5. Bridge IP Configuration window You also need to check that the “Access Point” option is enabled under the “Operational Mode” submenu (Figure 4-6).

Access Point Configuration Figure 4-7. SNMP Wireless LAN menu and submenus Phy Params (Figure 4-8): • Channel: Select the channel to be used. There are 14 channels available. • Rate: Select the rate to be used among the following options 1 Mbps, 2 Mbps, 5.5 Mbps and 11 Mbps.
Access Point Configuration Figure 4-8. Wireless Physical Parameters window Privacy Options (Figure 4-9): There are four 5 Hex digit encryption keys available, and you must define the value of the key of your choice. This key is enabled only if the you select it in the “Default key” option. Enable the WEP (ON/OFF) option in order to activate WEP encryption.
Access Point Configuration Figure 4-9. Wireless Privacy Options window Operational Settings (Figure 4-10): • ESSID: Select the ESSID to be used. • Fragmentation: This is the option for the Fragmentation Threshold activation. • RTS Threshold: This is the option for the RTS Threshold activation. • Authentication Type (Open System, Shared Key, Both). • Preamble Type (Short, Long).
Access Point Configuration Figure 4-10. Wireless Operational Settings window Under the “Setup” menu you can either enable or disable SNMP traps, which are messages displayed in the right bottom corner indicating that an action related to the AP Bridge took place, such as: • Trap Reassociation: This trap message is sent when a Station’s reassociation request is received from the AP - Bridge.
Access Point Configuration Finally, the “Info” menu contains “Wireless and Ethernet Statistics”. 4.1.3 How to Uninstall the SNMP Manager In order to uninstall SNMP Manager you must go to the ‘Control Panel” (“Start>Settings->Control Panel”) and press the “Add/Remove Programs” button. Select the application from the list and press the “Add/Remove...” button. Press “Yes” when asked whether you want to remove this program and its components. A window indicating the uninstallation progress appears. 4.
Access Point Configuration Figure 4-12. DFU Utility Bridge Configuration window The current parameters of the Bridge can be retrieved by pressing the “Get” button in the Bridge Configuration dialog. You can update the bridge configuration parameters by setting them first and then selecting the “Set” button. Network Parameters: • Ethernet IP Address: The IP Address of the AP • Ethernet Subnet Mask: The Ethernet station and the Access Point must be on the same subnet.
Access Point Configuration • Preamble Type: Select Short or Long Preamble Type. • Authentication Type: Select Open System or Shared Key Authentication Type. WEP Keys: • WEP Key #1-#4: Set the value of the WEP key. WEP keys must be in HEX and in two bytes per character format e.g. if you want the WEP Key #1 to be 12345, then you must set it as 0102030405. • Default Key: Select which of the four WEP Keys is going to be used. By selecting 0, no WEP encryption will be used.
Section 5 Access Point Firmware Upgrade The AP firmware upgrade can be done either through the Ethernet port by using the TFTP Client Utility, or the USB port by using the DFU Utility. 5.1 Using the Ethernet Port In order to upgrade the firmware of the AP through the Ethernet port, you must first install the TFTP Client Utility, which is a powerful and reliable tool used for the remote firmware upgrade of the Access Point through the Ethernet port. 5.1.
Access Point Firmware Upgrade Figure 5-2. Type the IP address, browse for the file bridge.rom and download The Firmware Download procedure will be completed successfully if a message in the right bottom corner appears indicating “Firmware download has been completed”. If you receive the message “TimedOut”, in the right bottom corner, during the firmware download procedure, you need to check if the Access Point is powered on and if it has a valid IP address.
Access Point Firmware Upgrade Figure 5-3. DFU Configuration Utility Please keep in mind that this process needs some time to complete. When the DFU completes successfully a window appears indicating the status of the download (DFU succeeded, DFU failed). Finally, close the application and unplug the cable.
