three-pin switch, see Fig. 3 2: Location of connectors and principal components on the TOP
side.
The switch positions are explained below:
Fig. 5-2: TFT (XP2) Digital Panel Power Switch
Contacts 1-2 are closed - the digital panel is powered with
+3.3
V voltage.
Contacts 2-3 are closed, - it is powered by +5 V voltage.
Attention!
Be very careful when selecting the TFT panel power voltage! Incorrect power voltage setting
may make the panel inoperative. To define the exact value of the TFT panel power voltage,
please look at the reference information provided by the panel manufacturer or inquire this
information from the dealer, where such panel was bought.
5.3 Restoring Factory CMOS Settings (Clear CMOS)
In case the system fails to be loaded (e.g., because of incorrect BIOS configuration or incorrect
password), the settings saved in the CMOS may be cleared with the help of CMOS Reset (XP9)
switch, see Fig. 3 2: Location of connectors and principal components on the TOP side.
The CMOS Clearing sequence will be as follows:
1. Power off the system.
2. Close the CMOS Reset (XP9) switch with a jumper supplied with the module.
3. Power on the system.
4. Wait till BIOS data to appear on the monitor screen.
5. Power off the system.
6. Open the CMOS Reset (XP9) switch.
7. Power on the system.
8. Further loading will be performed with the factory CMOS settings.
9. Factory parameters will be saved in the Flash memory after the POST is over.
10. Start BIOS Setup if it is necessary to change the CMOS parameters.
