3. Software Installation The CD ROM contains a set up file setup exe which will launch an install shield This install shield will install the Cypress Demo Software onto the PC properly NOTE The software will only work under Win 2000 or XP It will not work under Win 95 98 or NT 2 2 Hardware Installation Make sure that the cross cable that is delivered with the system is used to connect the PC and evaluation kit When the software is installed properly the demo kits power supply can be switched on By default the board is configured not to use a DHCP server The default IP settings for the system are IP address 192 168 2 10 Netmask 255 255 255 0 Gateway 192 168 2 254 When you change the IP settings of the PC to make sure it is connected to the same subnet http 192 168 2 10 gives you a configuration status page The system can be used on a standard network environment or standalone with a cross cable to a PC default Important note If you power on the system and connect it using the cross cable to the PC but you are unable to get to the status page http 192 168 2 10 on the PC please contact your network administrator to make sure your PC is in the same subnet After the power is switched on or the reset button is pushed it takes approximately 10 sec before the FPGA is configured The reset button is the little white button on the side of the demo kit NOTE 1 Verify if there is communication between the board and the
