Chapter 2—Installation

2.8. Sources

The projector accommodates a wide range of formats from standard composite video to a multitude of computer graphics standard. It is critical to set up the projector’s source files to accommodate this range. Key parameters are the horizontal and vertical scan rates, interlaced or non-interlaced scanning, and plus/minus sync levels. The projector can handle up to 20 sources in one channel. The correct projector source file is matched and automatically selected for the source being received by the projector.

2.8.1.Types of Standard Composite Signals

There are a number of different standards for composite video.

These standards differ in relation to parameters such as signal timing and the encoding scheme for the "video" information.

Table 2.0-6 Standard Composite Signals

Signal	Description
NTSC 3.58/4.43	The most common for US consumer television.
PAL and	Standards used in Europe and Asia.
SECAM
RS-170	Closed circuit monochrome.

NOTE: The HJT Model 100 Projector can display NTSC, PAL,

SECAM and RS170 video only through the Quad Standard

Decoder Module (with Line Doubler) VIC option, or via an

External Scan Converter/Line Doubler or Quadrupler.

2.8.2.Red, Green and Blue Analog Signals

The most common input is separate red, green and blue (RGB) analog signals. The sync signals for RGB analog sources can be separate horizontal and vertical, composite (horizontal and vertical combined) or included with the green analog signal (sync on green).

2.8.2.1.Signal Inputs

The projector allows the source(s) to be connected directly to the projector via appropriate connecting cables. Signal input jacks are located on the projector’s rear panel (see Figure 2.0-9 Standard RGBHV and Optional HDTV Input Connections on page 2-10).

Connect the appropriate source inputs to the appropriate jacks on the rear panel of the projector. RGBHV is the standard input that is supplied with the projector. Other VIC options are available (refer to list on page 1-4).

NOTE: Connect composite sync (H/V) to the H input on the rear panel.

If using an Extron switcher, connect it to either Port A or Port B. A switcher can be connected to either port but only one (1) switcher can be used. The switcher must be selected under
