Jumper Description
JP1
LVDS BKLT, LVDS VDD, VIO PCI
JP2
Serial Termination, USB Host, LTE USB Selection
JP3
Serial Termination and PCI Power Disable
Input Voltage Selection: JP1
The baseboard accommodates an Input voltage selection Jumper,
JP1
, which enables input voltage signal
sources to be selected and configured. Settings for Low-Voltage Differential Signaling Back Light (LVDS
BKLT), Low-Voltage Differential Signaling Virtual Device Driver (LVDS VDD), can be configured. It can also
be used to set the voltage supplied to VIO power pins for PC/104 cards.
NOTE
: VIO voltage is used on most cards to supply the I/O Voltage for all PCI signals.
The following table describes Jumper Block
JP1
pinouts for LVDS BKLT, LVDS VDD, their designated
functions and VIO PCI voltage settings. The text in bold and italics mark the default configuration on
JP1
.
