  • Page 17: Setting Jumpers

    2.5 Setting Jumpers You may configure your card to match the needs of your application by setting jumpers. A jumper is a metal bridge used to close an electric cir- cuit. It consists of two metal pins and a small metal clip (often protected by a plastic cover) that slides over the pins to connect them.

  • Page 18: Clear Cmos (J1)

    2.6 Clear CMOS (J1) Warning! To avoid damaging the computer, always turn off the power supply before setting “Clear CMOS.” Before turning on the power supply, set the jumper back to “3.0 V Battery On.” This jumper is used to erase CMOS data and reset system BIOS informa- tion.
