HS-873P User’s Manual

To setup the LCD, you need the component below:

1. A panel with LVDS interfaces.

2. An inverter for panel’s backlight power.

3. A LCD cable and an inverter cable.

For the cables, please follow the pin assignm ent of the connector to make a cable, because
every panel has its own pin assignment, so we do not provide a standard cable; please find a
local cable manufacture to make cables.

LCD Installation Guide:

1. Preparing the HS-873P, LCD panel and the backlight inverter.

2. Please check the datasheet of the panel to see the voltage of the panel, and set the
jumper JVLCD to +12V or +5V or +3.3V.

3. You would need a LVDS type cable.

the single board computer is a customized version of the in dustrial standard BIOS for IBM
PC AT-compatible computers. It supports Intel x86 and compatible CPU architecture based
processors and computers. The BIOS provides critical low-level support for the system
central processing, memory and I/O sub-systems.

The BIOS setup program of the single board computer let the customers modif y the basic
configuration setting. The settings are stored in a dedicated battery-backed memory,
NVRAM, retains the information when the power is turned off. If the battery runs out of the
power, then the settings of BIOS will come back to the default setting.

Appendix D <Programming GPIO’s>

The GPIO can be programmed with the MSDOS debug program using simple
IN/OUT commands. The following lines show an example how to do this.

GPIO0...GPIO7 bit0……bit7

-o 2E 87 ;enter configuration

-o 2E 87

-o 2E 2A

-o 2F FD ;enable GPIO function

-o 2E 07

-o 2F 07 ;enable GPIO configuration

-o 2E F0

-o 2F xx ;set GPIO as input/output; set ‘1’ for input,’0’for output

-o 2E F1

-o 2F xx ;if set GPIO’s as output, in this register its value can be set

Optional :

-o 2E F2

-o 2F xx ; Data inversion register ; ‘1’ inverts the current value of the bits ,’0’
leaves them as they are

-o 2E 30

-o 2F 01 ; active GPIO’s
