Figure 3: Connecting to the VP-731 Rear Panel 12 VP-731 - Connecting the VP-731
5.1 Connecting a PC You can connect to the unit via a crossed RS-232 connection, using for example, a PC. A crossed cable or null-modem is required as shown in method A and B respectively. If a shielded cable is used, connect the shield to pin 5. Method A (Figure 4)—Connect the RS-232 9-pin D-sub port on the unit via a crossed cable (only pin 2 to pin 3, pin 3 to pin 2, and pin 5 to pin 5 need be connected) to the RS-232 9-pin D-sub port on the PC. Note: There is no need to connect any other pins.

6 Presentation Switcher / Scaler Buttons The VP-731 includes the following front panel buttons: 6.1 • Nine INPUT selector buttons • A PIP button • BLANK and FREEZE buttons • Six OSD navigation buttons • A RESET TO XGA/720p button • A PANEL LOCK button Switching an Input Each INPUT SELECTOR button can be used to select the source. When selected, the button illuminates. You can switch seamlessly between each input that is connected to a source by pressing the appropriate INPUT SELECTOR button.
6.2 The PIP Button Feature The Picture-in-Picture inserter (PIP) uses K-IIT XL™ image insertion technology to present video and graphic sources simultaneously so that you can display: • An inserted video source PIP over a graphic source background • An inserted graphic source PIP over a video source background VIDEO SOURCE – can be composite or s-Video GRAPHIC SOURCE – can be HDMI, UXGA or component For example, you can show a live video window on top of a graphic background and vice versa.
6.2.2 Selecting the PIP Source To easily select the PIP source, press and hold the PIP front panel button while pressing the input button of the required PIP source. For example, to select PC 2 as the graphic PIP source over a video background, press the PIP front panel button while pressing the PC 2 front panel button. To select the PIP source using the IR remote controller, press the desired PIP source on the remote controller.
To replace a PIP source in the same category (for example, changing the PIP source from HDMI 2 to HDMI 1), press the required PIP Source on the remote control transmitter and the PIP display will change accordingly. i 6.2.3 When attempting to select a PIP source of the same category as the background source (for example, video on video, which is not compliant with the table on Page 19), a message is displayed, “Unavailable Operation”.

6.4 The Infrared Remote Control Transmitter You can control the VP-731 remotely from the infrared remote control transmitter which is powered by two AAA size 1.5V DC batteries. The IR remote control transmitter has a range of up to 15 meters and delivers instantaneous results i The front panel UNIVERSAL INPUT selector buttons IN 1 and IN 2 are named Input 1 and Input 2, respectively, on the IR remote control transmitter.
7 Configuring the VP-731 via the OSD MENU Screens The VP-731 uses an on-screen display (OSD) menu for system configuration. The menu appears as an overlay over any images that are output from the VP-731. There are eight sub-menus that are used to configure the VP-731. You can activate and navigate these menus from the front panel buttons, or from the IR remote control.
