VP-772 - Overview
3.1 HDCP Compliance for HDMI inputs
If an HDMI signal is HDCP protected, it can only appear on HDMI
outputs that are connected to HDCP compliant displays.
The VP-772 will not output a picture on an HDMI display that is not
HDCP compliant; instead it will show a green screen.
In the PiP mode (see Section 7.2), even if only one of the inputs is HDCP
protected, and is output to a non-compliant display, it will affect the
entire screen and turn it green.
When using a VGA output display, the screen will turn black.

5 Connecting the VP-772
Always switch off the power to each device before connecting it to
your VP-772. After connecting your VP-772, connect its power and
then switch on the power to each device.
You do not have to connect all the inputs and outputs, connect only
those that are required.
To connect the VP-772, as illustrated in the example in Figure 3, do the following:
1. Connect up to eight sources (for example, a PC, BluRay Disk Player,
Composite DVD player and so on) to the DVI INPUT connectors, according
to the Input OSD setup, see Section 6.2.
Use the ADC-DMA/5BF-1 and AD-DM/GF adapters provided with the package when
connecting a YUV, VGA or CV input, as required
2. Connect the audio input signals to the AUDIO IN terminal block connectors,
as required, see Section 5.2 (not shown in Figure 3).
3. Connect the PREVIEW OUT DVI connector to a DVI acceptor (for example,
an LCD display).
4. Connect the PROGRAM OUT DVI connector to a DVI acceptor (for
example, a projector).
Note that when high output resolutions (such as 4k2k@30) we
recommend that you use a DVI to HDMI cable (for example, the
Kramer C-HM/DM 6’ or 10’).
For lower resolutions you can connect the HDMI connector on a
device to the DVI connector on the VP-772 via a HDMI-DVI adapter
5. Connect the AUDIO OUT 1 and OUT 2 Terminal Block connectors to up to
two balanced analog audio acceptors, see Section 5.2 (not shown
in Figure 3).
6. If required, you can connect a PC and/or controller to the:
RS-232 terminal block (see Section 8.2.1)
Ethernet connector (see Section 8.2.2

6.4.1 Selecting the Correct Aspect Ratio
You can configure the aspect ratio of any output image to fit your application. The
VP-772 offers four different aspect ratio settings: Follow Input, Follow Output, Best
Fit and Letterbox. Here is how each of these settings works.
FOLLOW INPUT – The aspect ratio and resolution of the
input video or graphics signal are both preserved (no
scaling). For example, a composite video image with a 4:3
aspect ratio will appear with the same aspect ratio on a
1080p (16:9) output image, surrounded by black bars
FOLLOW OUTPUT – The aspect ratio and resolution
of the input signal is re-sized to precisely match the
aspect ratio and resolution of the VP-772 output
signal. This may result in some distortion to the input
signal images
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.
For example, a composite video signal (4:3 aspect
ratio) will “best fit” to the top and bottom of a
widescreen output image, resulting in black pillars on
either side.
Page 27
22
VP-772 - The OSD Menu
LETTERBOX – This setting compresses the top and
bottom edges of the input signal, but fills the width of
the screen. For example, to preserve a widescreen
film image on a 4:3 display. When not using a 4:3
resolution, this mode is identical to Best Fit

6.5.1 The Luma Keying Feature
The luma keying feature lets you display the Preview window (the key image) as
semi-transparent over the Program window. This feature can be used to have the
Preview window display a static or dynamic logo, for example, which will appear on
a transparent background.
To apply the luma keying feature, first set the Preview window to the desired size
and location and then turn luma keying On. The Preview image will show without its
background.
The lower the luminance in the Preview window, the more transparent it becomes,
thus letting the Program window image show. The higher the luminance, the less
transparent it becomes, not letting the Program window show through. To use this
feature it is recommended to set the Preview image as follows: use low-luminance
colors for the background (the key image portion) and high-luminance colors for the
logo.

VP-772 - The Layout
7 The Layout
The VP-772 can function in two modes, the:
Transition mode
Overlay (Picture in Picture) mode
The operation modes are set by selecting the display Mode via the Layout menu
(see Section 6.3).
7.1 The Transition Mode
In the transition mode you can setup the input, view it via the preview output and
then switch it to the PROGRAM output.
The VP-772 has two outputs: a PREVIEW output, and a PROGRAM output. Each
of these outputs functions independently. An input is routed to the PROGRAM
OUTPUT by pressing that PROGRAM INPUT front panel button. In the same way
pressing a PREVIEW INPUT front panel button will route that input to the
PREVIEW OUTPUT.
Use the PREVIEW output to:
See how the scaled output looks before displaying live during a presentation
Harmonize the transition to the PROGRAM output after determining the look
and feel when in the PREVIEW output
Use the OSD menu to make adjustments and choose the settings
When in the transition mode, you can set the speed of the transition, and determine
the type and direction of the transition via the OSD menu (see, Section 6.3).
For example, select Cut for an instantaneous transition from the PREVIEW output
to the PROGRAM output or select Chessboard for a chessboard transition effect
and check Swap to interchange the preview with the program.
To switch the inputs in the transition mode via the OSD menu, you need to set the
audio signal, define the effects and select the input:
Page 30

VP-772 - The Layout
7.2 The Overlay Mode
In the Overlay mode both outputs are identical and can display a single image
(single window display mode), two images one over the other or two images side by
side (dual window display mode).
A selected Program input appears as the main image in a dual window display
mode (such as PiP) or as the only image in a single window display mode.
A selected Preview input will appear as the PiP window in the dual window display
mode and will not appear at all in the single window display mode.
The overlay settings item in the Layout menu (see Section 6.3) lets you set a Single
Window, Picture in Picture (PiP), Picture + Picture (PoP) or Split images. For
example, you can show a live video window on top of a graphic background, or
show two images on screen of the same input channel. The PiP window appears
even if no input signals are connected. In this case the PiP window appears in dark
gray and the main window appears in light gray.
The preset PiP configurations are available:
Picture-in-Picture, with a smaller PiP
window superimposed over a full main
window image
Picture + Picture, where both images
appear side-by-side and the aspect
ratios of both images are maintained
Page 32
VP-772 - The Layout

VP-772 - The VP-772 RS-232 Communication Protocol
11 The VP-772 RS-232 Communication
Protocol
The Kramer Protocol lets you control the VP-772 from any standard terminal
software (for example, the Windows® HyperTerminal Application).
11.1 Using the Communication Protocol
There are three different methods to control the VP-772 RS-232 or the Ethernet:
Protocol commands mimicking the OSD, see Section 11.2
The button functions mimicking the remote controller buttons (as well as the
front panel buttons), see Section 11.3
Protocol 3000 common commands, see Section 11.4
All three tables together include all the protocol commands, but they are
not identical and do not always include the same information. Some of
the data may appear in one or two of the tables but not in the third table
and vice versa.
The protocol 3000 communications protocol uses a data rate of 115200 baud, with
no parity, 8 data bits, and 1 stop bit.
11.2 Communication Protocol: Mimicking OSD
The audio/video protocol commands define all the function numbers, their valid
parameters can be used with protocol 3000.
11.2.1 Using the Communication Protocol with Protocol 3000
(the “Y” Command)
Set Command:
Type in: “Y Control_Type=0,Function,Param”
Reply: “~id=01Y Control_Type=0,Function,Param OK”
Set command example: set HDCP mode for input 1 (113) to “On”
Page 54
VP-772 - The VP-772 RS-232 Communication Protocol
49
49
Get Command:
Type in: “Y Control_Type=1,Function”
Result: “~id=01Y Control_Type=1,Function,Param”
Get command example: get HDCP mode for input 1 (113):
Send: “#y 1,113”
Result: “~01@y 1,113,1”
You can add a last parameter, to be located fourth in SET or third in GET,
to define a specific window.
For example:
Set H Sharpness value to 10 on the Program window (1): “#y 0,343,10, 1”
Get H sharpness of the Main window (0): “#y 1,343,0”
The “Y” command also supports the value increment/decrement of any command
using the ‘+’ or ‘-‘ signs as the third parameter of the “Y” command.
For example, in order to decrease the volume on input 1 (116)
Send: “#Y 0,116,-,1<CR>”
Reply: “~01@Y 0,116,-,1 OK”
Note that if the value after the decrease is out of range, the reply will show an error
such as:”~01@Y ERR -03”

11.2.2 Protocol Table: Mimicking OSD
You can associate a function number to its description and valid parameters
intuitively by navigating the OSD menu according to the following logic:
A function number is directly related to its location in the OSD menu.
For example, the second menu on the OSD is Layout (2 in the hundreds). The third
menu item in Layout is Overlay Settings (2 in the tens), therefore the function
number for it will be 230 (2nd item on the Main menu and the 3rd item in the Layout
submenu (see also Section 6.1). When navigating in the OSD MENU you will be
able to see the Overlay Settings valid parameters.
Page 55
50
VP-772 - The VP-772 RS-232 Communication Protocol
Note that for the Inputs, menu levels 3, 4 and 5 are valid for each input
from 1 to 8. For example, Type (3rd level) item is 111 for Input 1 and 121
for Input 2, and so on. In order not to repeat the Inputs menu for each
input, the function list will have an x denoting the input number from 1 to 8.
For example the Type item will have 1x1 as the function number x being
from 1 to 8.
The following table shows the Program function numbering.
Note that some items that appear in red on the OSD menu seem missing
in the table below. These items will be enabled in future firmware and will
be described in detail.

The Program and the Preview menus are identical therefore one table is
shown for both. The only difference would be in the function number:
Program functions start with a 3 and Preview functions start with a 4.
For example, Aspect ratio is 321 for the Program aspect ratio and 421 for
the Preview aspect ratio.
