1 Introduction Welcome to Kramer Electronics! Since 1981, Kramer Electronics has been providing a world of unique, creative, and affordable solutions to the vast range of problems that confront the video, audio, presentation, and broadcasting professional on a daily basis.
2 Getting Started We recommend that you: • Unpack the equipment carefully and save the original box and packaging materials for possible future shipment • Review the contents of this user manual Use Kramer high performance high resolution cables • i 2.1 Use only the power cord that is supplied with this machine Go to http://www.kramerelectronics.com to check for up-to-date user manuals, application programs, and to check if firmware upgrades are available (where appropriate).
3 Overview The VP-725N is a presentation scaler/switcher with multiple signal format sections. The unit has five independent 4x1 video sections: composite, s-Video (Y/C), component (YUV), computer graphics, and HDMI, plus a single USB input. It also scales any video input up or down to a selectable graphics or HDTV output resolution and provides glitch-free switching between sources through FTB™ (fade-thru-black) switching technology.
• • Multiple color space – RGB or YUV output Embedded audio on the HDMI inputs and outputs The embedded audio feature is not available for the RGB resolutions 1920x1200 and 1920x1080. (It is available for 1080p) • HDMI channel support of up to 2.25Gbps bandwidth per graphic channel Suitable for resolutions up to UXGA at 60Hz, and for all HD resolutions.
• Can be firmware upgraded in the field via the USB port on the front panel • Includes worldwide power supply – 100-240V AC on a standard 19” rack mount size, 3U Rack "ears" included • HDMI channel supports up to 2.25Gbps bandwidth per graphic channel Suitable for resolutions up to UXGA at 60Hz, and for all HD resolutions. Control the VP-725N from the front panel and a user-friendly menu-driven OSD (see Section 7.1), or: 3.1 • From the front panel high contrast LCD Display (see Section 7.
In particular, HDMI: • Provides a simple interface between any audio/video source, such as a settop box, DVD player, or A/V receiver and video monitor, such as a digital flat LCD / plasma television (DTV), over a single lengthy cable SIMPLICITY - With video and multi-channel audio combined into a single cable, the cost, complexity, and confusion of multiple cables currently used in A/V systems is reduced LENGTHY CABLE - HDMI technology has been designed to use standard copper cable construction at up to 15

4 Installing in a Rack This section provides instructions for rack mounting the unit.
5 Connecting the VP-725N Presentation Switcher/Scaler This section describes how to connect the VP-725N. In particular, how to connect the: • VP-725N rear panel (see Section 5.1) • Interlaced and progressive RGBS and RGsB inputs (see Section 5.2) • PC (see Section 5.3) • Ethernet port (see Section 5.4) Using the VP-725N you can select any one of the 21 inputs and scale that input to up to three scaled outputs (at the identical resolution). 5.
Up to four HDMI sources (for example, DVD players) to the HDMI connectors 2. Connect the CV OUT BNC connector, and the UXGA OUT 15-pin HD connector to the respective video inputs on the projector. 3. Connect the HDMI connector to an LCD display. 4. Connect the COMP OUTPUT BNC connectors: G/Y, B/Pb, and R/Pr to the respective component video inputs on the LCD monitor. 5.

Method B (Figure 5)—Connect the RS-232 9-pin D-sub port on the unit via a straight (flat) cable to the null-modem adapter, and connect the null-modem adapter to the RS-232 9-pin D-sub port on the PC. The straight cable usually contains all nine wires for a full connection of the D-sub connector.
4. Select Internet Protocol (TCP/IP) and click the Properties Button (see Figure 6). Figure 6: Local Area Connection Properties Window 5. Select Use the following IP Address, and fill in the details as shown in Figure 7. This IP address is compatible with the factory default IP address of the unit. Figure 7: Internet Protocol (TCP/IP) Properties Window 6. Click OK. 5.4.
6 Operating the VP-725N Presentation Switcher/Scaler The VP-725N includes the following front panel buttons: • A set of 21 INPUT SELECTOR buttons • Video Group and Scaler Mode SELECT buttons • A PIP button • A FREEZE button • A set of 7 OSD buttons: OSD ON, MENU, ENTER, -, +, UP, and DOWN This section describes how to: 6.1 • Switch an input to an output (see Section 6.1) • Use the PIP feature (see Section 6.2) • Lock and unlock the front panel buttons (see Section 6.
6.2 Understanding the PIP Feature The Picture-in-Picture inserter (PIP) (see Section 7.1.2) is used to display video and graphic sources simultaneously.
Move the position of the PIP by: • Using the OSD menu (see Section 7.1) Choose a new PIP source by: • Pressing the "PIP Source" button on the remote control transmitter followed by the button of the desired PIP input • Pressing and holding down the PIP front panel button and then pressing the button of the desired PIP input (while the PIP button is still pressed) 6.
7 Configuring and Controlling the VP-725N This section describes how to configure and control the VP-725N via the: • OSD menu (see Section 7.1) • LCD display (see Section 7.2) • Infrared remote control transmitter (see Section 7.4) You can also control the VP-725N via the Ethernet (see Section 7.3) 7.
7.1.1 The Input Screen Figure 9 defines the Input screen.
7.1.2 The Picture Screen Figure 10 defines the Picture screen.
7.1.3 The Output Screen Figure 11 defines the Output screen.
Output Screen Setting Function Aspect Ratio Set the aspect ratio: Best Fit - The best possible compromise between the input and the output aspect ratios Letterbox Follow Output - Scales the picture to fill the entire output screen Selection/Range Default Follow Output When the input and output aspect ratios are the same, the only available option will be Follow Output. (The HQV considers 16:10 (for example, WUXGA, i.e.
7.1.1 Selecting the Correct Aspect Ratio You can configure the aspect ratio of any output image to fit your application. The VP-725N offers six different aspect ratio settings: Best Fit, Letterbox, Follow Output, Virtual Wide, Follow Input, and Custom. Here is how each of these settings works. BEST FIT – This setting re-sizes the video or graphics input signal to “best fit” the output resolution while maintaining the aspect ratio of the input signal.
7.1.2 The PIP Screen Figure 12 defines the PIP screen. Figure 12: PIP Screen PIP Screen Setting Function On/Off Activate/deactivate the PIP feature: On/Off Default Off When PIP is activated and that input is not connected, the PIP window appears black.
