Every time you service the embedded box computer, you should be aware of this. 3.2 Setting jumpers You can configure your DVS-350 to match the needs of your application by setting jumpers. A jumper is the simplest kind of electrical switch. It consists 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” a jumper, you connect the pins with the clip. To “open” a jumper you remove the clip. Sometimes a jumper will have three pins, labeled 1, 2, and 3. In this case, you would connect either pins 1 and 2 or pins 2 and 3.
The jumper settings are schematically depicted in this manual as follows: A pair of needle-nose pliers may be helpful when working with jumpers. If you have any doubts about the best hardware configuration for your application, contact your local distributor or sales representative before you make any changes. 3.3 COM2 RS-485/232 Jumper setting (JP2) The COM2 port located on front metal face plate of DVS-350 unit which can be configured to operate in RS-485 (default setting) or RS-422 mode by setting up the Jumper Pins of JP2 located on internal motherboard of DVS-350 unit.

The unstable power source might cause the shot-down to the system and the data loss.
4CHAPTER Award BIOS Setup
Chapter 4 Award BIOS Setup 4.1 Introduction Award’s BIOS ROM has a built-in setup program that allows users to modify the basic system configuration. This type of information is stored in battery-backed memory (CMOS RAM) so that it retains the setup information when the power is turned off. 4.1.1 CMOS RAM Auto-backup and Restore The CMOS RAM is powered by an onboard button cell battery. When you finish BIOS setup, the data in CMOS RAM will be automatically backed up to Flash ROM. If operation in harsh industrial environments causes a soft error, BIOS will recheck the data in CMOS RAM and automatically restore the original data in Flash ROM to CMOS RAM for booting. Note: If you intend to change the CMOS setting without restoring the previous backup, you have to click on "DEL" within two seconds of the "CMOS checksum error..." display screen message appearing. Then enter the "Setup" screen to modify the data. If the "CMOS checksum error..."message appears again and again, please check to see if you need to replace the battery in your system. 4.2 Entering Setup Turn on the computer and check for the “patch code”. If there is a number assigned to the patch code, it means that the BIOS supports your CPU. If there is no number assigned to the patch code, please contact Advantech’s applications engineer to obtain an up-to-date patch code file. This will ensure that your CPU’s system status is valid. After ensuring that you have a number assigned to the patch code, pressing <Del> to allow you to enter the setup
