4.12.8 Video Input
As described above, the onboard VGA controller C&T69000 is capable to handle a 16-Bit wide video
input data stream, generated by the video input chip from PHILIPS SAA7111A. This chip communicates
with a kind of I
2
C bus to the PCI VGA chip.
Up to three analog inputs can be connected to the SAA7111A with the actual software. The three input
channels are VIN1, VIN2 and VIN3. All of them are composite video input sources (CVBS). Each input
signal you will find at the connector J25, splitted with the VGA output signals. Most of used video cam-
eras are supplyed by +12V input voltage.
Connect the camera to the video input
You have to connect both cables of the video camera with one of the three input channels at J25.

Software drivers
There isn’t a need of a special driver for video input support. You will find a demo-software for Windows
’95 on the DIGITAL LOGIC CD.
With this program we can support only Windows ’95 with resolution of 640x480 and 800x600. Other
resolutions or OS are not supported at this time.
After starting the tool, there isn’t any video input picture on the screen first. Choose the right input
channel number in the menu context to enable the video mode.
Please read the readme- file on our cd to get more detailed information and the way how to proceed.
