v25 v26 38 38 Please note that you may have additional connections to the WARP boards, beyond those identified above. If, for example, you have recently worked through the exercise titled [http://warp.rice.edu/trac/wiki/Exercises/FPGABoardIntro INTRODUCTION TO THE WARP FPGA BOARD], then you may have a serial cable and a USB cable connected between your WARP boards and their corresponding computers. 39 39 40 The user DIP switches on one WARP kit should be set to the binary value 0000. The user DIP switches on the other WARP kitshould be set to the value 0001.40 The user DIP switches on one WARP node should be set to the binary value 0000. The user DIP switches on the other WARP node should be set to the value 0001. 41 41 42 42 [[Image(OFDMReferenceDesign/Files:setup_05a.jpg)]] 43 43 44 When power is applied to the WARP nodes, the value on the each board's 7-segment display (the onecloser to the user DIP switches) should reflect these settings -- either "0" or "1".44 When power is applied to the WARP nodes, the value on the each board's 7-segment display (the display closer to the user DIP switches) should reflect these settings -- either "0" or "1". 45 45 46 The compact flash configuration DIP switches permit the selection of different FPGA programs from a selection of programs stored on a compact flash card. If you are configuring the FPGA boards using a compact flash card (instead of from a USB connection), then the configuration switches must be set to the correct value for the desired program. In general, demo applications will be delivered on a compact flash card at location 0, so set the configuration DIP switches to the value 0000. DEPENDING UPON YOUR BOARD REVISION, THE SILKSCREEN NEAR THE CONFIGURATION DIP SWITCHES MAY INCORRECTLY SPECIFY THE DIRECTION FOR SWITCH VALUES 0 AND 1! The value 0000 is achieved when all switches are pushed away from the nearest board edge.46 The compact flash configuration DIP switches permit the selection of different FPGA programs from a selection of programs stored on a compact flash card.

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".71 Once the first FPGA board has been configured, the compact flash card may be removed for use in configuring of the other board.
