CONNECTIONS
Computer/Input 1
The computer port enables you to connect your computer to the projector using a
standard 15-pin D-sub VGA cable.
DVI input/Input 1
The projector supports connection to a DVI (Digital Visual Interface), which enables
you to connect any device with DVI-D (Digital Only) output.
RS-232
The standard RS-232 port enables you to connect the projector to a PC and upgrade
the projector firmware through a PC or control the projector using RS232 com-
mands. See Appendix E for more information about RS232 controls.
Note: The firmware upgrade is located on the CD that came bundled with
the projector. Contact your dealer for information on future upgrades.
Component/ Input 2 & 3
The projector supports two component video devices (Input 2&3). Component video
is typically transmitted in either YPbPr/YCbCr or RGB (Red/Green/Blue) formats.
Component video connections provide the best picture quality and are preferable to
S-Video and Composite Video connections.
Note: The PbPc/YCbCr color model is used for encoding video. Pb/Cb is
the luminosity of the black and white signal. Pb/Cb and Pr/Cr are color
difference signals. Pb/Cb is blue minus Y (B-Y), and Pr/Cr is red minus Y
(R-Y). The Premiere 50HD DLP Projector provides three standard RCA
phono plugs (x 2) to support YPbPc/YCbCr component video output.
S-Video/Input 4
Connect a DVD, VCR, or DTV decoder source device with the S-Video cable to this
socket. S-video separates pictures into chrominance and luminance signals provid-
ing a high quality image that is preferable to a composite video connection.
Composite Video/Input 4
Connect a DVD, VCR, or DTV decoder source device to this socket.
