2.1 Jumpers
2.1.1 Jumper Options
This section provides instructions on how to configure the motherboard by setting
jumpers, and also outlines the default motherboard settings and options for each
jumper.
2.1.2 Setting Jumper on main board
The motherboard can be configured according to the application requirements with
the setting of jumpers. A jumper is a metal bridge used to close an electrical circuit.
Jumpers typically consist 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” (or turn ON) a
jumper, connect the pins with the clip. To “open” (or turn OFF) a jumper, simply
remove the clip. Some jumpers comprise a set of three pins, labeled 1, 2, and 3. With
these jumpers, simply connect either Pins 1 and 2, or Pins 2 and 3. A pair of needle
nose pliers may be necessary for setting jumpers.
2.1.3 CMOS Mode Selection (JRTCTEST1)
The jumper can erase CMOS data and reset the system BIOS information. This
jumper is typically set with Pins 1 and 2being closed. To reset the CMOS data, set J1
to Pins 2 and 3 as closed for a few seconds before moving the jumper back to Pins 1
and 2 as closed. This procedure resets the CMOS to its default settings.
