Chapter 1 Introduction ACR-201-G is an 802.11g compliant radio with a 100-BaseT interface that acts as a Wireless Adapter. What separates the ACR-201-G from many other 802.11g-compliant radios is that its 100-BaseT interface affords a true plug-and-play feature that is unavailable from any other 802.11g Station radios that are based on either a PCMCIA or a USB interface and require the installation of a driver on the host device.
ACR-201-G Radio Key Features Plug & Play — o No driver on the host device is required for radio operation o Radio operation is independent of the operating system on computer or any connecting device (Windows 98/2000/ME/XP, MAC, Linux, Unix, embedded, etc.), as long as the device has a properly supported Ethernet port. Industry standard IEEE 802.
Chapter 2 Installation Safety Statements Use only the power supply adaptor provided with this product or the manufacturer's authorized replacement power supply. Connect the power cord to a properly grounded electrical outlet that is near the product and easily accessible. Refer service or rep airs, other than those described documentation, to a professional service person.
Steady ON, when Ethernet connection is not present.
If the yellow LED stays on continuously, then the Ethernet connection to the Ethernet port is not made. Check your UTP cable and make sure that a straightthrough cable is used for connecting it to a host and that a crossover cable is used for connecting it to a hub or switch. If one cannot communicate, and the yellow LED is off, you may want to re-position the ACR-201-G to a different location for better RF reception.
System Requirements for Web-based Utility program A Web-based Configuration Utility is a built-in program of the Wireless Adapter for changing the configuration settings of the Adapter. For using the ACR-201-G Web-based Configuration Utility, your computer must meet the following requirements: (1) A Web browser must be installed on the computer. The supported Web browsers include Internet Explorer 5.0 and above, Netscape 6.0 and above, and Mozilla 1.0 and above. JavaScript for the browser must be enabled.
Chapter 3 Web-Based Utility Software Use the Web-Based Utility Program Once the ACR-201-G is properly powered up and connected to a computer running a Web browser on the same IP subnet, the Web-based Utility is ready for use. To access the web utility, open a Web browser and enter http:// followed by the current IP address of the ACR-201-G in the location field, for instance http:// 169.254.98.
the browser would retrieve new web pages instead of displaying the cached web pages. Basic Information The “Info” page (Figure 1) is the default home page for the built-in web server. You can click on the “Info” tab to access this page. There are three subsections in this web page: Access Point Information, Bridge Information, and Available Access Points.
1. Access Point Information: This section displays the information of the wireless connectivity status of ACR201-G. Each field is described below. State The connection status of the wireless port Wireless Network Name (SSID) Shows the SSID of the AP. To change, see “Wireless Configuration” Tab “Wireless Network Name (SSID)”. Channel Shows the channel the AP is operating on. To change channel, see “Wireless Configuration” Tab “Channel”.
Intersil Firmware Version Shows the version info of the Intersil firmware. Ubicom Firmware Version Shows the version info of the Ubicom firmware. 3. Available Access Points This field displays the available access points detected by the ACR-201-G Bridge. Wireless Under this selection, you can configure the basic 802.11g access point settings. Any new settings will not take effect until the access point is rebooted.
digits into each key box. A hex digit is either a number from 0 to 9 or a letter from A to F. Leaving a key box blank implies a key of all zeros. Figure 3.
This check box allows users to enable or disable WEP feature. While WEP is disabled, all the other fields on this “Encryption” page are disabled too. A set of four keys needs to be created in the default-key scheme. Default WEP Key to Use Select the key to be used as the default key. Data transmissions are always encrypted using the default key. The other keys can only be used to decrypt received data. Deny unencrypted data: Check this field when the WEP is enabled to deny unencrypted data.
that no frames are ever fragmented. The valid range of fragmentation threshold is 256 to 2346, and only even numbers are allowed. Figure 4.
Transmitted wireless packets larger than this size will use the RTS/CTS protocol to (a) maintain performance in noisy wireless networks and (b) prevent hidden nodes from degrading performance. To minimize the potential packet collision associated with hidden nodes in a wireless network, IEEE 802.11 standard has the option to complete a “Request to Send (RTS)” and “Clear to Send (CTS)” two-frame exchange prior to sending the real data. This reduces the throughput of the real data.
2. IP Settings: IP Address Mode Select 'DHCP' to get the IP settings from a DHCP server on your network. Select 'Static' to use the IP settings specified on this page. Default IP address Type in the IP address of your Access Point. Allows the user to set a static IP address to the Wireless Adapter. This IP address is only used for accessing the built-in Web server. In order to access the Web server, the computer must use an IP address on the same subnet of the Wireless Adapter.
Figure 5.
3. Security User Name This is the user name that you must type when logging in to these web pages. Administrator Password This is the password that you must type when logging in to these web pages. You must enter the same password into both boxes, for confirmation. The built-in Web server will verify the login name and password before giving access to the hosted pages. Each time the user name or password is changed, the Web server will prompt the user for the new user name and password. 4.
Chapter 4 Troubleshooting No Page Displayed When Accessing the Web-based Utility This is either because the radio is extremely busy on the RF side or because the Ethernet connection is problematic. Try hitting the “Refresh” or “Reload” button of the web browser a few times. If the same message persists, it is unlikely that the problem is caused by a busy radio. Check your Ethernet connection. Make sure you use at least a legitimate CAT-3 cable, but preferably a CAT-5.
• Make sure that the UTP cable connecting the radio and the host device meets at least the CAT-3 standard and has a straight-through connection, not a crossover. • Make sure that the ACR-201-G is not connected to a hub with multiple computers/devices plugged in. • Make sure that the IP address of the host computer/device is properly set up for the network. • Make sure that the host computer/device has initiated some packet traffic since the radio was turned on.
• Reseat the ACR-201-G radio to a location where the interference is minimized; in general, increase the distance between the wireless devices and the device causing the radio interference. • Avoid using 2.4GHz cordless phone in the vicinity of the radio • Keep the computer with the ACR-201-G radio away from the microwave oven and large metal objects. • Consult the dealer or an experienced radio technician for help.
