For this card ATMEL currently provides Device Drivers for MS Windows ® 98/2000, and Windows ® Me. ATMEL also provides tools for the configuration and firmware upgrade of the cards. These tools, as well as the installation procedure for the MS Windows 98/2000, and Windows Me operating systems are described in this document. To install the adapter and operate under an operating system two pieces of software are needed. The first one is the driver, which provides the necessary mechanisms to the operating system in order to use the adapter as any other networking adapter. The driver communicates with the firmware using exchange of commands (Set MIB, Get MIB, Scan, Sync, etc.). The other piece of software needed is the code written on the MAC chip, which is responsible for the interface with the driver, and for the implementation of the IEEE 802.11b functions. 1.1 Package Contents Please make sure that your received the following with your AT76C503A-Evaluation Kit: • Two (2) Fast-VNET USB (A) cards • Two USB Cables • Two antennas • User Guide • Firmware, Drivers, and Software Tools CD 1.2 System Requirements • Operating System: MS Windows 98/2000, Windows Me with Service Pack 4 or later • Desktop PC or notebook PC with CD-ROM drive 1.3 AT76C503A Features AT76C503A based Fast-VNET adapters offer compliance with the IEEE 802.11b specification. This feature allows them to communicate with wireless devices from other manufacturers that support the standard. Among the features of the AT76C503A WLAN MAC controller are the following: – Wireless interface following the IEEE 802.11b standard supporting DSSS 2.4 GHz wireless PHY – Wireless LAN MAC Unit with ARM7TDMI RISC processor – Integrated 128-byte transmit and 128-byte receive FIFOs, for wireless MAC layer functions – 16-bit PCMCIA bus interface – Glueless SRAM interface for all MAC operations, supporting up to 16 MB of external memory – Integrated 6Kx32 bit internal SRAM, used for fast program code execution and temporary storage of data – Glueless Flash memory interface, supporting up to 16 MB on non volatile memory for permanent storage of program code – Enciphering/deciphering of wireless data by the implementation of the WEP algorithm – Supports 11, 5.5, 2, and 1 Mbps rates 1.4 Firmware Features The IEEE 802.11b firmware implementation for the AT76C503A-EK supports: – Distributed Coordination Function CSMA/CA Backoff Procedure NAV Management ACK Procedure Retransmission of unacknowledged frames – RTS/CTS Handshake – Duplicate Detection and Recovery – Beacon Generation (ad-hoc mode) – Probe Response (ad-hoc mode) – Fragmentation and Reassembly – Wired Equivalent Privacy Algorithm (WEP-40 bits, 128 bits) – Auto Rate Fallback – TSF synchronization – Short Preamble 1.5 Driver Features The drivers for the AT76C502-EK support: – Roaming – Preferred AP – Dynamic configuration – Site Survey – Preamble Type detection – Firmware Upgrade – Authentication Algorithm (Open System, Shared Key) Section 2 Installation Overview This is a quick step by step guide on how to install your Fast-VNET USB (A) adapter. Please follow the steps described below and refer to the appropriate sections for further details: • Power on the computer (laptop). • Please make sure that you don’t insert your USB (A) adapter yet. • Install the drivers and application: Insert the given Installation CD into your CD-Rom drive. Select the Utilities & Drivers folder. Locate the executable file “setup.exe” and double click it. Follow the installation…
