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). Secondly, when configured as
a Station, the 10-BaseT interface affords it a true plug-and-play feature that is
unavailable from any other 802.11b Station radios are based on either a PCMCIA
or a USB interface and require the installation of a driver on the host computer.
This driver-less feature also means that the operation of the radio is OS
(operating system) independent.

When configured as a Station, i.e. ACR-201, the driver-less feature enables
wireless connectivity for any computing devices/systems installed with any OS
(operating system), as long as an Ethernet communication port is available.
Ethernet-equipped workstations in a corporate environment, for example, benefit
greatly from this driver-less feature—the IT workforce has one less driver to
worry when upgrading an OS or when salvaging an OS crash. Special
computing/networking devices, such as printer servers, POS (point of sales)
machines may not even have an easy way of installing a driver for a radio.

When configured as an AP, i.e., ASR-102, AirEZY-2411-BT, offers a no-frill,
seamless way of fitting a wireless network into an existing wired LAN
infrastructure. It does not even require the assignment of an extra IP address.
Existing wired-network resources such as DHCP, VPN, firewall, etc., reach
across the ASR-102 to the client workstations with total transparency. Unlike
many other 802.11b APs on the market, which offer network functions that are
duplicative to the existing network, this AP simply wirelessly collects a group of
workstations or other kinds of computing devices into the existing network—just
like a hub.

AirEZY-2411-BT has a compact form-factor that blends easily into a home/office
environment. It also lends particularly well to portable applications. The
specifications are given on the next page.

A Utility program is needed to pre-configure AirEZY-2411-BT prior to putting the
radio in operation. And the Utility program can be used to monitor the
communication condition once the radio is in operation. Once configured, the
radio runs self-sufficiently without the aid of any driver program in the host
computer connected to the radio. This Utility program therefore is intended to be,
in most cases, just a tool for the network operators. An end user simply plugs the
pre-configured radio into a host computer or a network device equipped with a
RJ-45 receptacle without ever being expose to this Utility program. The Utility
program is simple to install and easy to use through its graphic user interface.
The details are described in Chapter 3.

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 wall outlet or from the USB or the PS2
port of a notebook computer through special adapter cables (call OTC to find out
more about these optional cables), or through a battery pack.

Power can also be supplied to the AirEZY-2411-BT over the Ethernet cable with
the used of an optional dc-extractor box near the radio and an optional dc­injector at the NOC side. This scheme is particularly useful when AirEZY-2411­BT is deployed as Access Point at a location without an installed AC outlet.

Ethernet Connection

When configured as a
Station, , i.e., ACR-201,
the AirEZY-2411-BTcan
be connected to a
computer’s, or a printer­server’s Ethernet port via
the included Straight­through UTP cable.
Please note that, as
dictated by the 802.11
standards, only one MAC
address can be supported
by a Station radio. As a
result, an AirEZY-2441-

BT configured as a
Station will not function
properly when connected to a hub plugged in with multiple
computers/network-devices. So as a rule, straight-through cable is always

used to connect an AirEZY-2411-BT Station to a computer or a network device.

When configured as an Access Point, i.e., ASR-102, the AirEZY-2411-BTcan be
connected to a server computer, a hub, a switch or a router. A straight-through
cable must be used when connecting to the Ethernet port of a server computer, a
cross-over cable, however, must be used when connecting to a hub, a switch or
a router.

Status LEDs

Connect the 10BaseT port (which resembles an over-sized telephone jack) on
the bottom panel of the AirEZY 2411 BT to the 10 BaseT port in the client
computer or computing device using the 3-ft straight-through UTP cable included

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 transmitting RF signal

LINK YELLOW Flickering when communicating over the Ethernet

port; steady-on when Ethernet connection is absent

If the yellow LED stays on continuously, then the Ethernet connection to the host
computer or device is not made. Check your UTP cable and make sure that a
straight-through cable is used for connecting directly to a host. A cross-over UTP
cable is needed if connecting to a hub. If the yellow LED is not lit, and power is
on to the device, then the Ethernet connection between the host computer and
the Wireless Ethernet Adapter is correct. If one cannot communicate, and the
yellow LED is off, you may want to re-position the AirEZY-2411-BT to a different
location for better RF reception. You may also want to check if the unit is
configured with the proper RF channel and security settings by using the Utility
software.

Once the hardware is checked out to work properly with the intended host device
or network equipment, the radio can be secured in the desire location by the pair
of Velcro tabs.

Installing the Utility Software

System Requirements

To use the AirEZY-2411-BT Wireless Ethernet Adapter’s utilities software, your
computer must meet the following minimum requirements:
Windows® 95 (OSR2)/ 98 (SEC)/ME/2000/XP
Ethernet capable computer with RJ-45 port (either built-in or add-on NIC)

Installation

To install the utility program, simply insert the CD-ROM provided and the
installation process will finish with you clicking a few “OK”. The installation copies
the Utility program and its run-time support (components of Visual Basic) onto
the host computer without altering any settings of the host computer..

Notice that the operation of the AirEZY-2411-BT is independent of the Utility
Program. Therefore, it is NOT necessary to install the Utility on the network­device/computer that you plan to install the AirEZY-2411-BT. For example, if you
plan to connect a printer server wirelessly to the network with the AirEZY-2411­BT, you do not need to have the Utility Program installed on the printer server—
you will not be able to! In this example, you configure the AireEZY-2411-BT as a
Station on a PC installed with the Utility Program, disconnect it from the PC, then
connect it to the printer server. While the Utility program must run on a computer
equipped with Microsoft Windows, the radio can operate with computers/devices
of any OS.

Also notice that to configure or monitor the radio with the Utility program, the
computer running the Utility program can be either directly connected to the radio
or connected to the same subnet the radio is connected to.
