Overall Functional Description
The
VX-5000ci system
consists of the
PFP Controller
and the
VX-5000ci Projector
. This system 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 (or similar) 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 VX-5000ci Projector. The Composite, S-Video and
Component (non-progressive) signals are sent through the PFP Controller's 10-bit decoder, de-inter-
laced, 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 VX-5000ci's image, including typical 'front-panel controls' as well as color
temperature and other image-quality controls.
