Setting the Jumpers
Jumper Types
Jumpers or headers are small pins attached to the system board. Covering two pins with a shunt
closes the connection between them. The ATXP-965Q examines these jumpers to determine
specific configuration information. There are two different categories of jumpers on the ATXP-965Q.
A. Two pin jumpers are used for binary selections such as enable, disable. Instructions for this type
of jumper are open, for no shunt over the pins or closed, when the shunt covers the pins.
B. Three or four pin jumpers are used for multiple selections. Instructions for these jumpers will
indicate which two pins to cover. For example: for JPx 2-3 the shunt will be covering pins 2 and 3
leaving pins 1 and 4 exposed.
Pin 1 can be identified by looking to the solder side (The board side with fewer components) of the
PCB (Printed Circuit Board). Pin 1 will have a squared pad. Other pins will have a circular pad. They
are numbered sequentially.
Double row jumpers are numbered alternately, i.e. pin number 2 is in the other row, but in the same
column of pin number 1. Pin number 3 is in the same row of pin 1, but in the next column and so
forth.
