An adapter cable IDC10 to Sub-D HD15 female for CRT Monitors and several cable
adapters for a direct connection of the display are available.

1.23 Video Input Port

The CT69000 has a digital video input port that may be used for overlaying a picture on
the screen. The data of the video input port is directly transferred to the video output and is
therefore not accessible by other application programs. The video input port cannot be
used as a frame grabber device. The signals of the video input port are located on the
video input port connector. Because the signals on this connector are routed directly to the
pins of the CT69000 the user may have to build his own hardware around to connect a
video device like a camera.
The video input port is located on the bottom side marked as VIDEO CON in the drawing.
The video input port is not available on all board models, but only on the model that in-
cludes all peripheral functions (TV-OUT, Sound, Ethernet, Graphics Controller).

1.24 TV-OUT

The TV-OUT option offers the possibility to connect directly a TV. The VGA-Signals (RGB)
is converted on board to a BAS signal (COMP) and a S-VHS signal (LUMA and CRMA).
The signals are located on a 12-pin IDC header (1,27 mm).
TV-OUT can be used together with a CRT Monitor or stand-alone. For proper timing of the
TV signals the currently used VGA mode must be changed to PAL or NTSC timing by a
VGA BIOS call via software interrupt 10h, function 5F19h (examples in assembler):
For PAL timing:
Because the setting will be lost if the VGA mode changes, this must be executed when-
ever the VGA mode changes. To come back to normal VGA timing the software interrupt
looks like this:

the on board power supply. This 3,3 Volt must be not used
to supply connected displays with high power consump-
tion.
