DW-1100 Access Point Users Guide

- 1 -

Introduction The DW-1100 (IEEE 802.11b compatible 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. DW-1100 is a highly integrated Access Point designed to combine legacy LANs with wireless LANs. DW-1100 performs all the necessary inter-networking and bridging functions. It receives data from both networks, stores them locally for further processing, installs and maintains connections and transmits the packets to the proper destination. This User Guide describes the steps required for the initial set up of the AP IP address, the AP configuration, and the firmware upgrade procedure. The description includes the implementation of the above steps through both Ethernet and USB. Package Content System Requirement Features Please make sure that you received the following Content:

AP Configuration The DW-1100 AP configuration can be done through the Ethernet port either by using the SNMP Manager application or through the USB port by using the AP Utility Application. In order to configure the DW-1100 AP through the Ethernet Port/Wireless 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/Wireless Port. In order to install the SNMP Manager you need to run the program setup.exe which you will find in the Utilities folder in your CD. Follow the instructions of the set-up program and select the directory where the application will be installed. Finally, a window appears indicating the completion of the installation. Connecting to AP using SNMP 1. On the Start Menu, choose Start -> Programs -> SNMP Manager. 2. File menu: When the application opens, under the File Menu there are the following submenus:

3. Connect to AP - Using this submenu you can directly connect with the Access Point by typing its IP Address in the panel that appears and at the Community field, type "public"

and then press OK (Figure 1). Figure 1 Connecting to Access Point using SNMP Manager 4. In case of a successful connection to the Access Point, the following window appears. Press OK (Figure 2).

(version 1.4) Figure 2 Access Point Found 5. In case of an unsuccessful connection you receive the following message (Figure 3):

Figure 3 Access Point Not Found 6. If the above error message appears, you need to check if the AP is connected to the network. Configuring the AP using SNMP 1. When the connection has been successfully established, you get a message in the left bottom corner indicating, Get Configuration done and on the right bottom corner the IP Address of the connected Access Point. 2. File menu: The file menu contains the following enabled submenus

" Close Connection AP - Terminates the connection with the Access Point.

" Download Changes - When all the desired values of the parameters have been set you are able to download the changes (save the changes) to the Access Point by selecting this submenu.

" Options - Defines the polling interval according to which the SNMP Manager polls the Access point in order to update the statistics and the Associated Stations List. 3. Setup menu: As soon as the connection has been established, you are able to start viewing or setting the Access Point parameters. Under the Setup menu, there are the following submenus:

" Bridge - Under the Bridge submenu, the only option is:

IP Configuration: By choosing this option the window appears. The IP Address and IP Mask can be modified through IP Configuration. If changes are made, you need to Download Changes under the File menu in order to save them. Please refer to Table 1 and Figure 5 Parameters Ethernet Address The MAC Address of the Access Point. Description IP Address IP Mask Unique 48-bit, hard-coded Media Access Control address known as the station identifier. Network-assigned Internet Protocol address of the Access Point. Four sets of three digits that divide a network into sub networks. Table 1 Bridge IP Configuration Parameters

" Wireless LAN - Under this submenu there are the following two options available.

# Privacy Options - By choosing this option you must define the encryption key values of your choice. There are four 5 Hex digit encryption keys available. The key is enabled only if you select it in the Default key option. Enable the WEP option in order to activate WEP encryption for transmissions between the station sand the Access Point. (Figure 6 and Figure 7) Note: The encryption level must be the same on the wireless station and on the access point. All shared keys on the wireless station must be the same as those on the access point with which the client station is associated. Figure 6 SNMP Wireless LAN menu and submenus

# Operational Settings - Using this option, you can either view or modify the Wireless LAN parameters of the Access Point (Figure 4-10). These parameters are described below:

ESSID Channel Fragmentation threshold RTS Threshold Authentication Type It is an ASCII string up to 32 characters and it is used to identify a WLAN that prevents the unintentional merging of two co-located WLANs. The ESSID value must be the same in all stations and Access point in the extended WLAN. Select the ESSID to be used. There are 14 channels available. The channels differ from country to country. Select the channel to be used. The size at which packets will be fragmented. Choose a setting within a range of 256 to 2346 bytes. Minimum packet size to require an RTS (Request To Send). For packets smaller than this threshold, an RTS is not sent and the packet is transmitted directly to the WLAN. This is the option for the RTS Threshold activation. Select Open System, Shared Key, or Both

! Open System: With this setting, any station in the WLAN can associate with an Access Point and receive and transmitted data (null authentication)

! Shared Key: With this setting only stations using a

shared key encryption identified by the Access Point are allowed to associate with it.

! Both: with this setting, stations communicate with the Access Point either with or without data encryption. Preamble Type

(Short/Long) Rate:

Auto Rate Fall Back Preamble is the first sub-field of PPDU, which is the appropriate frame format for transmission to PHY (Physical layer). There are two options, Short Preamble and Long Preamble. The Short Preamble option improves throughput performance. By default, the unit adaptively selects the highest possible rate for transmission. Select the basic rates to be used among the following options 1/2 (Mpbs), 1/2/5.5/11 (Mbps). When this is enabled, the transmission rate is the optimum rate. In case of obstacles or interference, the system will automatically fall back. Regulatory Domain The value of this field is already set and cannot be modified.

" Enable SNMP traps - Using this submenu you can either enable or disable SNMP traps, which are messages displayed in the right bottom corner of the main window indicating that an action related to the AP took place. Permitted messages are:

! Trap Reassociation: This trap message is sent when a Stations reassociation request is received from the AP - Bridge.

! Trap Association: Indicates the reception of an association request packet and

the sender Station's successful association with the Wireless Bridge.

! Trap Disassociation: This trap message is sent when a disassociation notification packet is received from a Station.

! Trap Reset: This trap message is sent when the AP-Bridge resets.

! Trap Setting IP Address with Ping: This trap message is sent when the AP-Bridge IP address is set with the transmission of a ping message.

! Trap Start Up: This trap message is sent when Bridge starts up.

! Trap Failed To Erase Flash: This trap message is sent when Bridge fails to erase flash. 4. Traps menu: Provides information for trap messages

" View Record - You can see additional information for every Trap Message 5. Commands menu: Under this menu there are two submenus.

" Reset Device - You can reset the Access Point. This action takes place after a user makes configuration changes in order to initiate the changes.
