Addendum: Scalers Group Additional Features of the Scaler Products Group according to the Master-Firmware Ver-2.33 Release. 1. This version requires Slave Firmware version 1.06 or higher. The version can be seen in the INFO section of the on-screen menu. Contact your Kramer service center if you have any questions. 2. Improved functionality lets you select the PIP source via the RS-232 command. Sending an inappropriate PIP source command (request video PIP source while the main video input is selected; or the same for graphic sources) will not cause the unit to operate erroneously. In such a case, the unit will ignore the command and return the message: “ineffective source”. This option does not apply to the VP-719DS. 3. Added PIP position(s) commands in the RS-232 protocol. These commands let you input the absolute value (from 0 to 36) of the horizontal and vertical positions of the PIP. For details, see the protocol table. This option does not apply to the VP-719DS. 4. Added new output resolution 1280x768. This resolution is marked with an asterisk “*” to attract your attention to the fact that this is not a standard VESA resolution and its parameters vary from manufacturer to manufacturer. Therefore, this resolution must be used with caution. It is also possible to use the parameters of this resolution in combination with the User Defined resolution (see below). There is also an RS-232 command for this resolution. For details, see the protocol table. 5. Added 50 Hz output refresh rate. This is for special cases only. Many of the modern screens and projectors have difficulties working with such a low frequency. 6. In the OSD under UTILITIES>ADVANCED there is new item: “Input Button”. This item defines an action after repeatedly pressing the same input selection button. This item has following options: �� FREEZE/BLANK – this is the current situation (quoting from the user manual: Press again (when the LED illuminates) to freeze the image; the LED flashes. Press once again (when the LED flashes), to display a blank screen; the LED flashes more slowly)). This remains the factory default �� FREEZE – pressing the button toggles between LIVE and FREEZE �� BLANK – pressing the button toggles between LIVE and BLANK �� IGNORE – after selecting the source, the button is ignored The settings also apply to the input buttons on the IR control. 7. Under the Utility>PIP Setting there is new item: “PIP Frame”. This feature allows the enable/disable yellow frame around the PIP through the OSD or the new RS-232 command: L 50AF. The RS-232 command allows PIP frame enable/disable while the PIP is activated. However, before doing it via the OSD you must switch the PIP OFF. While the frame is activated, pressing the UP and DOWN buttons on the front panel and on the IR remote control would toggle through the PIP size settings. This option does not apply to the VP-719DS.

A2 8. Under the Utility>Output Setting>User Mode Setting there is a new option: “Set Current”. This feature lets you apply the parameters of the currently selected output resolution to the User Define output resolution (Utility>Output Setting>Resolution). This set of parameters can be used as a “starting point” to adjust parameters according to the requirements of the signal receiver. The changes to the User Define parameters are applied immediately and require confirmation in the same part of the OSD. 9. In the OSD under UTILITIES>ADVANCED there is new item “User Define Measure”. This feature lets you modify the automatically detected parameters of the input graphic signal and save them in one of 3 sets for further use. The changes are applied in real time and therefore can be monitored directly on the screen. This feature is especially useful in working with non-standard input resolutions. The following parameters can be changed: H Total: Horizontal total H Start: Horizontal active start point H Active: Horizontal active region V Start: Vertical active start point V Active: Vertical active region Ch Pump: Charge Pump current Color: Color Format 10. Under the Utility>PIP Setting>PIP Size, there is a new option: “User Define”. This feature lets you set the size of the PIP to your exact needs. To use this option, select “User Define”, then press the “PIP User Define” bar and set the PIP V-size (0-2551) and H-size (0-2551). This option does not apply to the VP-719DS. 11. By pressing the +, -, UP and DOWN buttons continuously, you can speed up their response. For example, to roughly set the brightness to a higher level, open “Brightness and Contrast”>Brightness, and press and hold the + button. For step-by-step response, press and release these buttons as many times as needed. 12. New firmware supports an updated set of RS-232 protocol commands. These commands are available on our Web site at http://www.kramerelectronics.com 13. Under Geometry>Scale>Aspect Ratio there is a new option: “User Define”. This feature lets you adjust the geometry of the outputted picture. 14. A new refresh rate for HDTV resolutions. This new feature supports the HDTV outputs with 50Hz refresh rate2. 1 255 corresponds to a full screen 2 This option applies to machines that support HDTV resolutions

13 6.2 Understanding the PIP Button Feature The Picture-in-Picture inserter (PIP) is used for the simultaneous display of video and graphic sources, and lets you display: • An inserted video source1 PIP over a graphic source2 display • An inserted graphic source2 PIP over a video source1 display Your Seamless Switcher / Scaler automatically recognizes and displays only the relevant sources, as the following 2 examples illustrate: • Choosing the AV 1 PIP source when the VGA input is selected, will insert the composite video source over the VGA graphic displayed on the screen. You can choose a component, YC 1, YC 2 or AV 2 PIP source3 (instead of the AV 1). You cannot choose VGA 1, VGA 2 or DVI4 • Choosing the VGA 1 PIP source when the AV 1 input is selected, will insert the VGA graphic source over the composite video displayed on the screen. You can choose a DVI PIP source3 (instead of the VGA 1). You cannot choose AV 2, YC 1, YC 2 or component5 6.2.1 Activating the PIP Feature To activate the PIP (which illuminates the PIP LED), do one of the following: • Press the PIP button6 • Switch on the PIP functionality via the OSD Menu (see Figure 35) • Press the PIP key on the infra-red remote control transmitter (see Figure 49) When the Source Prompt is ON (see Figure 41), the PIP is enclosed by an orange frame, and the OSD PIP status appears superimposed over the top right corner of the screen for a few seconds, as Figure 5 illustrates. After a few seconds7, the orange frame and the OSD PIP status automatically disappear8. Activating the PIP subsequently cycles between the PIP with the orange frame and no PIP. 1 That is, composite, s-Video or component 2 That is, DVI or VGA 3 As long as it is connected and switched on. Otherwise, choosing it will display a blank screen 4 As these are graphics sources and you cannot insert a graphics PIP over a graphics source 5 As these are video sources and you cannot insert a video PIP over a video source 6 Item 24 in Figure 1 7 By default, 20 seconds. But you can reset the timeout (from 3 to 60 seconds), see section 7.3.6.6 8 Trying to activate the PIP again while the PIP is still enclosed by an orange frame deactivates the PIP

Understanding the Seamless Switcher / Scaler 14 Figure 5: OSD PIP Status When the Source Prompt is OFF (see Figure 41), activating the PIP toggles between the PIP (with no frame and no OSD PIP status) and no PIP. 6.2.2 PIP Characteristics You can determine the following PIP characteristics: • PIP Source • PIP Size (1/4, 1/9, 1/16, 1/25 or split screen) • Horizontal and Vertical position, placing it anywhere on the screen 6.2.3 Toggling between the PIP and the Screen Source (SWAP) To toggle back and forth between the PIP content and the screen source content, do the following: • Press the SWAP key on the Infra-red remote control transmitter (see Figure 49) The OSD SWAP status appears superimposed over the top right corner of the screen for a few seconds1, as Figure 6 illustrates Figure 6: OSD SWAP Status 1 By default, 20 seconds. But you can reset the timeout (from 3 to 60 seconds), see section 7.3.6.6

15 6.2.4 Resizing the PIP To resize the PIP (1/4, 1/9, 1/16, 1/25 or split screen): • When the Source Prompt is ON and the PIP is enclosed by an orange frame, use the Up and/or Down navigation control keys on the infra-red remote control transmitter (see Figure 49) or the UP and/or DOWN front panel OSD buttons • Use the OSD Menu buttons (see Figure 37) 6.2.5 Moving the Position of the PIP To move the location of the PIP: • When the Source Prompt is OFF, use the four navigation control keys (see Figure 25) on the infra-red remote control transmitter (see Figure 49) • When the Source Prompt is ON and the PIP is enclosed by an orange frame, use the preset position control keys (see Figure 24) on the infra-red remote control transmitter (see Figure 49), to instantly move the position of the PIP window to up to nine preset fixed locations1. When the Source Prompt is OFF, the preset position control keys have no effect 6.3 Locking and Unlocking the Front Panel You can lock the front panel2 and control from the infra-red remote control transmitter to safeguard the settings on the VP-720DS or VP-723DS. To lock the front panel: • Press and hold the MENU front panel OSD button3 or the MENU key on the infra-red remote control transmitter (see Figure 49) for a few seconds, until the Key Lock On OSD status appears superimposed over the top right corner of the screen for a few seconds4, as Figure 7 illustrates Figure 7: Locking / Unlocking the Front Panel 1 For example, to move to the lower right corner of the image, press the button 2 However, operation via RS-232 serial commands (remote controller or PC) is still available 3 Item 23 in Figure 1 4 By default, 20 seconds.
