APPLICATION GLOBAL
Purpose of this interface is to take RGB signals from a computer and to display them on a large screen
projector, while keeping the image on the monitor intact.
As IBM and Apple computers need monitor identification for soft and hardware configuration purposes,
emulation of these identification bits is provided in case no monitor is connected.
In case a monitor is connected, the identification bits of the monitor are fed to the computer.
To obtain the best performing images on the large screen-projecting device, active loop-trough is used
for the monitor output.
RGB signals from the computer are automatically terminated to 75 Ohm, while sync signals, which are
TTL signals are terminated with a 22K pull-up resistor.

FRONT SIDE OF THE INTERFACE:
- DD15 input connector, labeled TO COMPUTER
With the provided DD15/DD15 cable any GA type Computer can be connected.
With an optional cable Apple Mac computers can be connected to the interface.
- 3 LEDs indicating the sync signals received from the computer. For GA (S GA, XGA) type
computers the H and led should light up. For Mac Computers composite might also, or only light up.
- ID bit selector.
This switch allows emulating a typical IBM or MAC Monitor. IBM and MAC computers need to know which
type of monitor is connected. In case no monitor ID bits are detected, no image is sent to the RGB
outputs resulting in no image on your projector.
In case Monitor identification is present, the software limits the selection options for output resolution.
This results in a safety situation for the monitor. The image will always be in its lock range, and will
always be  readable.
When a monitor is connected to the interface, the monitor ID bits are sent to the computer. In this case
the rotary switch is disabled, and the green LED ID enabled will stop glowing.
- Power indicator.
When the mains is connected this LED will indicate the power supply of the unit is up and running.
