P/N: 2900-0070144 A1
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.

Addendum: Scalers Group
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 (0-255
1
) and H-size (0-255
1
). 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 rate
2
.
1 255 corresponds to a full screen
2 This option applies to machines that support HDTV resolutions

7.2 Controlling the Seamless Switcher / Scaler
You can control the Seamless Switcher / Scaler via:
• The front panel OSD control buttons (see section 7.3)
• The infra-red remote control transmitter (see section 7.3.8)
• RS-232 remote control
7.3 Operating via the OSD MENU Screen
The OSD superimposes a menu on the screen from which you can control your
the VP-719DS, using the MENU, ENTER, -, +, UP and DOWN front panel
OSD buttons.
Pressing the MENU front panel OSD button or the MENU key on the
infra-red remote control transmitter (see Figure 42) displays the first OSD
screen, the “Menu screen” (see Figure 8), which displays six interactive
icons3(defined in Figure 9).
After initially pressing the MENU front panel OSD button or the MENU key
on the infra-red remote control transmitter, each subsequent press moves to
the previous level in the OSD screen (Esc.).
1 By default, 20 seconds. But you can reset the timeout (from 3 to 60 seconds), see section 7.3.6.5
2 Adjusting the output resolution results in a corresponding adjustment to the size of the OSD status window
3 Each icon represents a Level 1 function. In addition to Level 1, the OSD structure includes Level 2 (a subset of level 1),
Level 3 (a subset of level 2), Level 4 (a subset of level 3) and Range
