Overall Functional Description
The DR-300c system consists of the PFP Controller and the DR-300c Projector. This sys-
tem is unique in the way it is controlled; the control center for this system is located within the
PFP Controller. The PFP Controller tells the Projector to turn on or off, controls its brightness,
contrast, color temperature and more. All of this is accomplished by Runco's unique ComLink,
which is the transfer of information between the PFP Controller and the Projector via their
ComLink ports on a CAT5 cable with RJ-11 ends. Therefore, only the PFP Controller's remote
control is necessary to control all aspects of this system.
Besides being the system's control center, the PFP Controller is also a high-quality scaler,
which outputs all signals in the native resolution of the DR-300c Projector. The Composite, S-
video and Component (non-progressive) signals are sent through the PFP Controller's 10-bit
decoder, de-interlaced, then scaled to the native resolution of the Projector. In the case of
HDTV or progressive DVD signals, these are input to the RGB/Component port.
In the next chapter, the menu system will be described in detail. There are many adjustments
available to perfect the DR-300c's image, including typical 'front-panel controls' as well as
color temperature and other image-quality controls.
