ADDENDUM: Ethernet Cross Cable Wiring Connection

P/N: 2900 - 9999993 A1

This addendum describes the correct wiring for crossover cable connections

and replaces the opening paragraph in the "Connecting the ETHERNET Port

directly to a PC (Crossover Cable)" section in the User Manual as follows:

Connecting the ETHERNET Port directly to a PC (Crossover Cable)

You can connect the Ethernet port of the machine to the Ethernet port on your

PC, via a crossover cable with RJ-45 connectors.

Table 1 and Figure 1 define the color codes for the two existing standard types

of cross cables used in the industry. Table 2 defines how to connect the wires

to the connectors on both ends of the cable.

When manually connecting the ends of a cable, both connectors must follow

the same standard (either EIA /TIA 568A or EIA /TIA 568B).

Overview

3 Overview

The VP-725DS Presentation Switcher / Scaler is designed for a wide variety

of presentation and multimedia applications. It is a true multi-standard video

to graphics scaler and presentation switcher for a wide variety of presentation

and multimedia applications. It consists of a very high quality scaler with many

user-selectable pixel-rates including VGA (640x480), SVGA (800x600), XGA

(1024x768), SXGA (1280x1024) and UXGA (1600x1200); high definition

television HDTV (480p, 720p and 1080i); and several optimum plasma and

LCD rates such as 852x1024i, 1024x1024i, 1366x768, 1365x1024, 1280x720,

720x483, 852x480, 1400x1050, 576P, 720x400, 832x624, 1024x800,

1152x864, 1152x870, 1152x900, 1280x960, 1280x768, 1024x576, as well as

a user definable output mode

In particular, the VP-725DS:

 Offers high quality de-interlacing 3:2/2:2 pull down

 Supports firmware upgrade via RS-232

 Includes non-volatile memory that retains the last setting, after switching

the power off and then on again

 Scales and zooms (to up to 400% of the original size)

 Digitally reprocesses the signal to correct mastering errors, and

regenerates the video at a chosen line and pixel rate format, providing, for

example, native-resolution video for LCD, DLP and Plasma displays

 Facilitates scaling of graphics resolutions to other resolutions

 Incorporates a unique graphics-scaling engine with image enhancement

algorithms, which are built into the firmware

 Is specifically designed to improve video quality by reducing chroma noise

 Includes an OSD (on-screen display) for making the adjustments that can

be located anywhere on the screen, and can be doubled in size. The OSD

can be used to deactivate the source prompt, choose the color of the blank

screen, and choose from three seamless switching transition speeds

 Consists of 5 video groups—composite video, s-Video, component video

(RGB or YPbPr), DVI-D and VGA—and each group has 4 inputs (except

for DVI which has 2 inputs)

1 Recommended for advanced users only – non-standard settings may not be recognized by the display device

2 Accommodates the frame-rate of a converted movie (24 frames per second) to video frequencies (25 frames per second

(PAL); 30 frames per second (NTSC)

KRAMER: SIMPLE CREATIVE TECHNOLOGY

Overview

 Has multi-standard video support; supports VESA standards; HDTV

standards and other popular resolutions on the input. Does not support

HDCP

(High bandwidth Digital Content Protection) on the DVI

 Features two modes of operation: Video Group Mode and Scaler Mode.

These modes function simultaneously and independently (except for DVI:

once a DVI input is selected in the Scaler Mode, that DVI input selection

cannot be changed in the Video Group Mode)

 Video Group Mode selects the input from each group: CV, YC,

Component, VGA, DVI for switching to its local (group) output

 Scaler Mode converts the selected input (one of 18) to the SCALED OUTPUTS

 Includes a front panel lock, as well as a separate OSD lock

 In addition to providing an up- or down- scaled output of the selected (one

of 18) inputs, also functions as 4x1 switchers for each video group (2x1 for

DVI)

 Has ProcAmp

controls for the scaler output

 Lets you freeze the image at any instant

 Lets you select the output colorspace (RGB or YPbPr)

 Has a text overlay feature

for insertion of subtitles, karaoke script, text

banners, and the like, which lets you send text to be displayed on the

scaled output

 Includes a built-in Picture-In-Picture (PIP) inserter

(letting you insert a

video source into a graphics background or vice versa. This PIP image

may be positioned and sized anywhere on the screen, or displayed as 2

images side-by-side (Split-Screen)

The VP-725DS:

 Comes in a rugged, professional 19" 3U rack-mountable metal enclosure

 Uses a universal 100-240VAC automatic power supply

1 A method of security encryption (developed by Intel and Silicon Image)

2 An HDCP source would show up as a very snowy, noisy picture at the output

3 Processing amplification enables adjustment of different video and audio signal parameters

4 The VP725 Text Overlay Application (Text Overlay Sender) for the VP-725DS (and the VP-725DSA) can be downloaded
