channel inputs to channel 1 to channel 16 with 7.5/6 fps per channel.
Also, user can set different 878A chip with different switch. For example, user can set the
chip1 to 1 input only, the chip2 to 3 inputs, the chip3 to 2 inputs, and the chip4 to 4 inputs.
Then, the channel 1 can run at 30/25 fps. The channel 2, 6 and 10 can run at 10/8 fps. The
channel 3 and 7 can run at 15/12.5 fps. The channel 4, 8, 12 and 16 can run at 7.5/6 fps. The
channel 5, 9, 11, 13, 14 and 15 will not accept any video signal with above setting. User can
set the video channel setting to meet the specific application situation.
For the DVS-350 series with Intel ULV Celeron® M 600MHz, user just can run it up to 8 video
inputs at 15/12.5fps.
Note: Above information are the characteristics of Conexant Fusion 878A video chip and
DVS-350 series. The actual frame rate and performance will depend on the video input

Chapter 3 Hardware Installation and Upgrade
3.1 Jumpers and Connectors
The DVS-350 Embedded/Mobile Video System consists of a PC-based computer that is
housed in a aluminum top cover, a metal bottom case with accessed bottom cover and front
with rear metal face plate. The HDD, SDRAM, are accessible by removing the accessed
bottom cover. Any maintenance or hardware upgrades can be easily completed after
removing the top cover, front and rear plates.
Warning!
Do not remove any mechanical parts, such as the top cover, bottom cover and front with rear
face plate until you have verified that no power is flowing within the embedded box computer.
Power must be switched off and the power cord must be unplugged. 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.

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  to allow you to enter the setup

Below is the demo program window. The left side panels are the preview windows of video
inputs. The right side panels are the function parameter settings.
6.3.1 Device
Each device is representative of one Conexant Fusion 878A video capture chip. User can set
different parameters to different 878A chip.
6.3.2 Switch Channels
Set the “Switch Channels” to decide how many input for each 878A video chip. Each 878A
chip can switch to 4 channel video inputs to share 30/25 frame per second. For more
information, please refer to “Chapter 2.2.3 Video Input Connectors” and “ Chapter 7.5.17
DVS300_SetVideoInput”.
6.3.3 Resolution
Set the video capturing resolution. Please refer to “Chapter 7.5.14 DVS300_GetResolution”
and “Chapter 7.5.15 DVS300_SetResolution”.
Notice: For the resolution of VGA or D1, the capture video will have the interlace effect on the
video image. In other words, there will be lines in the capture image especially when the
targeted image is moving. To eliminate this effect, user might need to set the resolution down
to 640x240 and use specific algorisms to compensate the image interlace between the
scanning even field image and odd field image. For CIF/320x240 resolution, there will be no
interlace effect.
6.3.4 Frame Rate
Set the frame rate for video capturing for specific channel. Please refer to “Chapter 7.5.12
DVS300_GetFrameRate” and “Chapter 7.5.13 DVS300_SetFrameRate”.
