1.9 Jumper Settings
This section provides instructions on how to configure your card by
setting jumpers. It also includes the card's default settings and your
options for each jumper.
1.9.1 How to set jumpers
You configure your card to match the needs of your application by
setting jumpers. A jumper is the simplest kind of electric switch. 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. To “close” a
jumper you connect the pins with the clip. To “open” a jumper you
remove the clip. Sometimes a jumper consists of a set of three pins,
labeled 1, 2 and 3. In this case you connect either pins 1 and 2, or 2 and 3.
A pair of needle-nose pliers may be useful when setting jumpers.
1.9.2 CPU core frequency (J5)
You must configure your PCA-6175 CPU card to the frequency of your
Intel Pentium
®
II processor by setting jumper J5. The PCA-6175 is
equpped to use Pentium processors with speeds of 233, 266, 300 and
333 MHz. Configure your PCA-6175 as follows:
