Section 1 About GL2411AP-0A Access Point

Introduction

The GL2411AP-0A (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. It receives data from both networks, stores them locally for further processing, installs and

maintains connections and transmits the packets to the proper destination. Furthermore, AT76C510 interfaces

three more modules, the Ethernet PHY, the wireless PHY and the RAM modules, for allowing compact

system implementation and flexibility for supporting almost all the possible physical interfaces.

1-1 Features

–Glueless connection to Intersil PRISMI, PRISMII Direct Sequence Spread Spectrum (DSSS) radio chip

set. Able to communicate also with other DSSS radios

–Supports 11 Mbps rates with automatic fallback to 5.5, 2 and 1 Mbps

–WEP encryption/decryption is accomplished on the fly

–Ethernet MAC supports MII interface and 10/100Mbit speeds

–Hardware modules for Packet Filtering and statistics gathering

–Glueless SRAM, Flash interface for data buffering and program storage, supporting up to 16 MB of

memory

–Integrated 2 x 6K x 32 bit internal SRAM modules for fast 32-bit program execution and temporary

storage of data

–Supports 3V supply

–128-pin PQFP, TQFP

–JTAG Boundary Scan (IEEE 1149.1) test access port for board-level production test

1-2 Firmware functionality

The firmware functionality of the bridge supports:

1. Distributed Coordination Function (DCF )

CSMA/CA

Backoff procedure

NAV management

ACK procedure

Retransmission of unacknowledged frames

2. RTS/CTS handshake

3. Duplicate detection and recovery

4. Fragmentation and Reassembly

5. Beacon generation

6. Probe response

7. Wired Equivalent Privacy Algorithm (WEP)

8. Authentication Algorithm (Open System, Shared Key)

1-3 Applications

The Serial of LAN products offer a fast, reliable, cost-effective solution, allowing clients to wirelessly

access the network in applications such as following:

1. Remote access to corporate network information

E-mail, file transfer and terminal emulation

2. Difficult-to-wire environments

Historical or old buildings, asbestos installations, and open area where wiring is difficult to employ

3. Frequently changing environments

Retailers, manufacturers and banks who frequently rearrange the workplace and change location

4. Temporary LANs for special projects or peak time

Trade shows, exhibitions and construction sites need temporary setup for a short time period. Retailers,

airlines and shipping companies need additional workstations for a peak period. Auditors require

workgroups at customer sites.

5. Access to database for mobile workers

Doctors, nurses, retailers, white-collar workers need access to database while being mobile in the hospital,

retail store or office campus.

6. SOHO (Small Office and Home Office) users

SOHO users need easy and quick installation of a small computer network.

Section 2 Hardware Installation

2-1 Equipment Requirement

Installation of GL2411AP-0A requires:

1.An A/C power outlet (100~240V,50~60Hz) which will supply the power for the GL2411AP-0A Access

Point

2.A 10/100 Base-T (UTP) Ethernet cable drop (RJ-45 connector)

2-2 GL2411AP-0A Hardware Installation

Please follow these procedures while setting up the hardware:

1. Site Selection

Choose a proper place for your GL2411AP-0A.

In general, the best location to place your GL2411AP-0A is the center of your wireless coverage, with line

of sight to all your mobile stations.

2. Adjust the direction of the Antenna

Adjust the direction of the antenna placement to improve the GL2411AP-0A’s performance. Try to place

the antenna in the position which can best cover its BSS. Normally, the higher you place the antenna, the

better the performance will be. The character of diversity enhances the receiving sensitivity.

3. Connect the Ethernet Cable

GL2411AP-0A can be connected to the 10/100 Base-T Ethernet network. Connect your UTP Ethernet cable

to the RJ-45 connector of the GL2411AP-0A AP and connect the other side of UTP Ethernet cable to a hub.

4. Connect the Power Cable

Connect the power adapter cable to the DC5V Power Socket of the GL2411AP-0A. ONLY use the power

adapter supplied with the GL2411AP-0A. Otherwise, the product may be damaged.

2-3 Software Limitation

1. DFU Software

Operation System:

Chinese Windows 98/2000/ME, English Windows 98/2000/ME

2. SNMP Software

Operation System:

English Windows 98/NT/ME

Section 3 How to Configure GL2411AP-0A Access Point

The GL2411AP-0A can be configured by DFU utility for only Windows®98. You need plug the USB

cable with the GL2411AP-0A and the USB slot of the PC to run DFU.exe for configuring the GL2411AP-0A

and setting the setup.

3-1 Installation GL2411AP-0A AP by USB cable For Windows 98

1. Because the utility is only for Windows®98 at this moment, you must boot your PC into Windows®98.

2. Run DFUzip.exe in GL2411AP-0A Access Point driver and utility disk to decompress the files into

C:\DFU.

3. Ensure you have followed the procedure as described in the previous section to finish hardware installation.

4. Plug the two sides of the USB cable into the USB slots of GL2411AP-0A and your PC.

5. Windows®98 will automatically detect the GL2411AP-0A and prompt you to install the necessary driver.

Click “Next” to begin the installation.

6. Select “Search for the best driver…” and click “Next”.

7. Select “Specify a location” and click “Browse”. On the windows information dialog, double-click the

“C:\DFU” folder icon from the list and Windows® 98 will automatically enter the path. Then click “Next”.

8. Windows®98 will then acknowledge that it has found the appropriate driver and click "Next".

9. Windows®98 will install the driver. As the driver files are being copied to the appropriate location, you

will be prompted to insert the Windows®98 CD.

NOTE: You must insert the Windows 98®CD as the driver installation requires special files that will not be

available even if you have stored a copy of Windows® 98 source on your hard drive.

10. After Windows®98 has finished installing the appropriate files, click “Finish”.

11. From the Control Panel, double-click the “System” icon.

12. From the “Properties” menu, please select the “Device Manager” tab. And check that the “BRIDGE

DFU DEVICE” device works fine.
