v21 v22 3 3 [[Image(OFDMReferenceDesign/Files:esd_warning.jpg)]] 4 4 5 By default, this project creates a custom wireless Ethernet link between two computers, each attached to a WARP kit (FPGA board + clock board + radio board). Each computer is unaware that a wireless link is present, and simply communicates with its neighbor using a standard wired connection. The WARP boards are "inserted" between the two computers to provide a transparent wireless bridge. The following diagram gives a simple overview of the configuration used forthis example.5 By default, this project creates a custom wireless Ethernet link between two computers, each attached to a WARP kit (FPGA board + clock board + radio board).

In this scenario, the computers must have their IP addresses hard-coded. Furthermore, the two computers must reside within the same subnet. The following addresses and subnet masks are just one example of acceptable settings for this demo: 53 53 54 - COMPUTER 1 IP ADDRESS = 192.168. 0.16,55 - COMPUTER 2 IP ADDRESS = 192.168. 0.17,54 - COMPUTER 1 IP ADDRESS = 192.168.1.16, 55 - COMPUTER 2 IP ADDRESS = 192.168.1.17, 56 56 57 57 - COMPUTER 1 SUBNET MASK = 255.255.255.0, … … 65 65 66 66 Switch the Master Power Switch for each FPGA board to the ON state. 67 Configure the FPGA boards using either 1) a compact flash card containing the demo program, or 2) a USB cable connected between the FPGA board and a computer running the Xilinx iMPACT software application. The laboratory exercise titled [http://warp.rice.edu/trac/wiki/Exercises/FPGABoardIntro INTRODUCTION TO THE WARP FPGA BOARD] provides a brief introduction to the iMPACT software application, including required cable connections. For configuration using a compact flash card, simply insert and the card from the appropriate slot on each FPGA board.67 Configure the FPGA boards using either 1) a compact flash card containing the demo program, or 2) a USB cable connected between the FPGA board and a computer running the Xilinx iMPACT software application.

Before removing it, however, verify proper configuration by examining the board's 7-segment LEDs. The one closer to the user DIP switches should display the value programmed into the switches -- either "0" or "1". 69 72 70 73
