1 Chapter 1 INTRODUCTION AirEZY-2411-BT is an 802. 11b compliant, or WiFi, radio with a 10-BaseT interface. Two features separate AirEZY- 2411-BT from many other 802.11b-compliant radios. Firstly, this 802.11b-compliant (WiFi) radio can be configured as either a Station (ACR-201) or an AP (ASR-102).
2 AirEZY-2411-BT (ASR- 102/ACR-201) WiFi Radio Specifications Model AirEZY-24 11-BT Standard 802.11 and 802 .11b Host Interf ace Ethernet, 802.3, RJ-45 receptacle Frequency 2.
3 Chapter 2 INSTALLATION Installing the Hardware Power This radio is capable of pulling power from either an AC adapter (supplied with the standard purchase) that plugs into a wa ll outlet or from the.
4 in the shipment. Power on the AirEZY 2411 BT, the LEDs on the front panel should exhibit the following patterns: LED Color Light Blinking Pattern ON RED Steady on RX GREEN Steady on TX RED on, when .
5 Three installation examples are shown below. Optional Hardware Radio with externally mount ed antenna (ASR-102E/ACR-201E) Power over Ethernet: DC-injector and dc-extractor 9V adapter if up to 120-ft.
6 Installing the Utility Software System Requirements To use the AirEZY-2411-BT Wireless Ethernet Adapter’s utilit ies software, your computer must meet the follo wing minimum requirements: Windows.
7 Chapter 3 UTILITY SOFTWARE Use the Utility Program Once the radio is properly turned on an d connected either directly to the computer running t he Utility program or to a port on the same subnet, the Utility is ready for use.
8 Configure AirEZY-2411-BT as an Access Point (ASR-102) By checking the “Change Role to AP” (r ed-arrowed in screen-shot #3), most parameter fields become undimmed and modifiable, as se en in screen-shot #3 .
9 Each field on this “Access Point” sub-tab is explained below. Device Name: Allows the user to enter a use r- defined name for the radio. Up to 32 bytes can be used. MAC: Displays the MAC address of the radio when it is configured as an AP. This filed cannot be modified.
10 exactly the same SSID as the SSID entered in this sub-tab. The tightest level of network access control is implemented in Level 3, [Hide SSID, Match SSID, Use Allowed List] , add one additional cri.
11 system” mode. When the “shared key” option is chosen, the “Encryption” tab of the Utility program must be properly filled out. Fragmentation Threshold: In the presence of hostile RF envir.
12 Configure AirEZY-2411-BT as a Station (ACR-201) Click on the “Station” sub-tab to display the “Station” page if the “Access Point” page is on top after clicking the “Configuration” tab. Similar to the case of configuring the radio for AP, checking the “Change Role to Station” undims the page and makes most fields modifiable.
13 PS Mode: Power Saving can be enabled only w hen “Infrastructure” is select ed for the “Network Type”. Channel: This field is modifiable only when the “Ad hoc” type is selected for “Network Type”. The Station automatically scans for the right channel to join when operated in the “Infrastructure” m ode.
14 applied to other Wi-Fi radios, however, may re sult in very different keys. For this reason, clicking the Apply button after entering the pass-phrase will caus e the 4 sets of keys being temporarily displayed under “Manual Entry” as if they were entered manually.
15 of the default keys for transmitting its data. When Use Dynamic WEP Key is checked, only 3 default keys are available for selection (Screen Shot #11).
16 transmitted data packets. “Signal Strength” directly measures the amount of RF energy received relative to a “maximum” expected for the best condition.
17 Notice also that in this manual mode th roughputs in Bits/Sec are not calculated due the imprecise timing. Uninstall the Utility Software If you need to uninstall the Utility softwar e for any reason, complete the following steps: 1. Close all programs that are currently running.
18 Chapter 4 TROUBLESHOOTING Blank Pages Appear When Open the Utility Program This is either because the radio is extr emely busy on the RF side or because the Ethernet connection is problematic. Try to hit the Refresh button a few times. If the blank-page condition persists, it is unlik ely that t he problem is caused by a busy radio.
19 • Make sure that the MAC address of the Station in question is properly entered into the “Allowed Station List” of the AP if enhanced security level 3, [Hide SSID, Match SSID, Use Allowed List] , is chosen. • Make sure that the Station in ques tion has exactly the same SSID as the AP if enhanced security level 2 or 3 is chosen.
20 • Make sure that the radio is not surrounded by many strongly reflecting (metallic) surfaces. With multiple refl ecting surfaces between the radio in question and the target radio, a severe “ multi-path ” problem may introduce high bit error rate despite a strong “Signal Strength”.
