Ampro Corporation 5001451A manual Jumper Summary, Jumper Group Function Default

Jumper Summary

Ampro installs option jumpers in default positions so that in most cases the Little Board P6d module requires no special jumpering for standard AT operation. You can connect the power and peripherals and operate it immediately.

Jumper-pin arrays are designated W1, W2, and so forth. Jumper pins are spaced 2 mm apart. A square solder pad identifies pin 1 of each jumper array. Table 2-2is a summary of jumper use. Factory settings are shown in the Default column. Some jumpers are set at the factory to configure options that are not user-settable. These are indicated in the table. Do not change these settings.
