Overview  
The Kramer VP-770 is a high quality presentation switcher and scaler. It accepts  
one of eight inputs: a component video on RCA connectors, a DisplayPort (DP)  
signal on a DisplayPort connector, two computer graphics signals on 15-pin HD  
connectors, two composite video signals on RCA connectors, and two HDMI signals  
on HDMI connectors. It scales the video, embeds the audio, and simultaneously  
outputs the signal to an HDMI output, to a computer graphics output and to a  
DGKat TP output, together with a digital audio output and an unbalanced stereo  
audio output.  
COMPONENT VIDEO is also known as Y, Pb, Pr, or Y, Cb, Cr or YUV; compatible with both  
SD and HD component  
The VP-770 Presentation Switcher / Scaler features:  
PixPerfect™ Scaling Technology – Kramer’s precision pixel mapping and  
high quality scaling technology. High-quality 3:2 and 2:2 pull down de-  
interlacing and full up and down scaling of all video input signals  
State-of-the-art video processing technology, with the highest quality de-  
interlacing, noise reduction, and scaling performance for both standard-  
definition and high-definition signals

picture−in−picture, picture−and−picture and split screen capability, or fully  
customizable windows’ size and position control: any source can be inserted  
into or positioned next to any other source and resized as desired  
Ultra Fast Fade-Thru-Black (FTB™) Switching - Video switching transitions  
are clean and ultra-fast. The video fades to black and the new input fades  
from black for smooth, glitch-free switching. The output signal provides  
constant sync so the display never glitches

3.1 HDCP Compliance  
If an HDMI signal is HDCP protected, it can only appear on HDMI  
and DGKat outputs that are connected to HDCP compliant displays.  
i
The VP-770 will not output an HDCP protected source to a display  
that is not HDCP compliant. Instead it will show a black screen.  
In the dual window display 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 black.  
3.2 About the Power Connect™ Feature  
The VP-770 can power the receiver on the DGKat output when the devices are  
within 90m (270ft) of each other. The Power Connect™ feature applies as long as  
the cable can carry power and the distance does not exceed 90m on standard TP  
cable. For longer distances, heavy gauge cable should be used (TP cable is still  
suitable for the video/audio transmission, but not for feeding the power at these  
distances).  
3.3 Using Twisted Pair Cable  
Kramer engineers have developed special twisted pair cables to best match our  
digital twisted pair products; the Kramer: BC-DGKat524 (CAT 5 24 AWG), the  
Kramer: BC-DGKat623 (CAT 6 23 AWG cable), and the Kramer: BC-DGKat7a23  
(CAT 7a 23 AWG cable). These specially built cables significantly outperform  
regular CAT 5 / CAT 6 / CAT 7a cables.

HDCP Mode – to select the HDCP option for the HDMI input: either ON (the  
default) or OFF.  
Setting HDCP mode to Off on the HDMI input allows the source to transmit  
a non-HDCP signal if required (for example, when working with a Mac  
computer).  
EDID Select – to select the native resolution on each input (HDMI, DP and  
VGA inputs) to be read by the video source connected to that input:

to be 8bpp or 12bpp after selecting the native resolution  
Note that when the EDID is set on the inputs, the changes are  
per input and immediate for PC 1, PC 2 and DP inputs.  
i
Setting the EDID on any one of the HDMI inputs affects that  
HDMI input immediately (the VP-770 automatically issues a hot-  
plug) and will affect the other HDMI video source only after a  
hot-plug occurrence on that input.  
For example, if the EDID is selected for HDMI2 it will affect the  
HDMI2 input immediately; the HDMI1 EDID will take effect  
following a hot-plug.  
Color Space – to select the color space for the PC and HDMI inputs: RGB,  
YPbPr or Follow Input  
Note that if the machine is set to the dual display mode, and both the Main

6.7.1  
Selecting the Correct Aspect Ratio  
You can configure the aspect ratio of any output image to fit your application. The  
VP-770 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-770 output  
signal. This may result in some distortion to the input  
signal images  
VP-770 - The OSD Menu  
33  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
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.  
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.  
6.7.2  
Master Connection Settings  
The Master Connection (HDMI, DGKat or PC) is usually set to the main output  
display so that the optimal resolution for that display can be obtained. By setting  
the output resolution to Native, the VP-770 is triggered to read the EDID of the  
main display and change the output resolution value according to the native  
resolution of the display.  
Note that when the output resolution is set to Native:  
If HDMI/DGKat is selected as the Master Connection, and a new display is  
connected to the Master Connection output (hot plug), the VP-770  
automatically reads the EDID of that display and updates the output  
resolution accordingly  
If it is not supported by the selected Master Connection, the system  
searches for the best supported resolution. If the search fails (for example, if  
the master connection is disconnected or EDID is unreadable), the  
resolution will default to XGA

The Luma Keying Feature  
The luma keying feature lets you display the PiP window (the key image) as semi-  
transparent over the main window. This feature can be used to have the PiP  
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 PiP window to the desired size and  
location and then turn luma keying On. The PiP image will show without its  
background.  
The lower the luminance in the PIP window, the more transparent it becomes, thus  
letting the main window image show. The higher the luminance, the less  
transparent it becomes, not letting the main window show through. To use this  
feature we recommend that you set the PIP image as follows: use low-luminance  
colors for the background (the key image portion) and high-luminance colors for the  
logo.  
For certain displays, the screen may flicker once for about a second  
after activating or changing the luma keying setting.  
i
Since luma keying is a volatile parameter, it may reset unexpectedly  
following a change in the setup. So we recommend that you activate it  
after completing the setup.  
When the luma keying feature is On, any change in the setup (either by  
the user or by resetting due to a setup change) may cause the screen to  
flicker once. The luma keying will recover automatically after resetting.

The Emergency Alert System  
The Emergency Alert System (EAS) is a unique, versatile feature for immediate text  
overlaying, with flexible options such as the inclusion of an audio alert siren and the  
choice of displaying an emergency notification via either a text crawler or a text  
window.  
The EAS provides the ability to have a site-wide notification immediately displayed  
when an emergency situation develops that could affect the health and welfare of  
the people attending the site, whether that site is an educational facility, a corporate  
site, a stadium or any other location where large groups of people come together.  
Messages can include specifics about weather (tornadoes, hurricanes, high winds,  
flooding, storms and so on), Amber and Silver alerts, safety and security, and also  
general advisories.  
Emergency alert messages are composed and transmitted using the Common Alert  
Protocol (CAP). CAP is an XML-based application that allows a warning message  
to be consistently disseminated simultaneously over many warning systems to  
many proprietary applications and devices. By using XML, messages can be  
composed, transmitted, and received across a broad range of proprietary AV and  
other devices.  
Generally, CAP format alerts can also trigger secondary functions, such as alert  
tones, horns, buzzers, and sirens. They can be used to switch on AV equipment to  
display alerts. The system also complies with the Emergency Alert System (EAS)  
standard, an official, national warning system in the United States, which works in  
coordination with the Federal Emergency Management Agency (FEMA) and a  
number of US national emergency agencies.  
For more details on CAP, go to https://www.oasis-  
open.org/committees/download.php/6334/oasis-200402-cap-core-  
i
1.0.pdf.  
The VP-770 intercepts XML files over the Ethernet in the CAP format via the  
dedicated EAS port from the alert generator server (for example, a FEMA server or a  
proprietary CAP message generation application) for immediate alert message  
triggering.

Figure 24: XML File Transfer  
The position of the displayed CAP message depends on the severity of the alert.  
Noticeable messages with “Extreme” and “Severe” headers will appear on the  
screen and cover up any other content together with an audio alert siren (in case of  
an Extreme level alert). Messages with lower levels of severity will appear as text  
crawler along the bottom of the image. When an alert is activated, the system (via  
P3K) outputs messages according to the activation mode type (see Section 12.4).  
Figure 25: Emergency Alert System Display  
The Expiration Date field of the CAP XML file determines when the message will  
expire. Note that you can remove the message sooner by pressing/clicking any of the  
buttons on the VP-770 (front panel or remote control buttons, as well as via the Web  
page or protocol commands).

Using the IR Transmitter  
You can use the IR transmitter to control the machine via the built-in IR receiver on  
the front panel or, instead, via an optional external IR receiver (Model:  
C-A35M/IRR-50). The external IR receiver can be located up to 15 meters away  
from the machine. This distance can be extended to up to 60 meters when used  
with three extension cables (Model: C-A35M/A35F-50).  
Before using the external IR receiver, be sure to arrange for your Kramer dealer to  
insert the internal IR connection cable (P/N: 505-70434010-S) with the 3.5mm  
connector that fits into the REMOTE IR opening on the rear panel. Connect the  
external IR receiver to the REMOTE IR 3.5mm connector.

Port Tunneling  
The port tunneling feature lets you send and receive simple RS-232 signals  
between a controller and a serial device via the VP-770 which is connected to the  
Ethernet and outputs via TP cable.  
The example, illustrated in Figure 33, shows a Kramer room controller that is  
connected to the VP-770 via the Ethernet. The DGKAT OUT connector on the  
VP-770 is connected via TP to a DGKAT receiver. This DGKAT receiver connects to  
a display via HDMI and RS-232.  
Figure 33: Port Tunneling  
The room controller sends RS-232 signals over the Ethernet via a dedicated  
Tunneling port to the VP-770. The VP-770 sends these signals via TP to a display  
that is connected to the receiver. This way, control data can flow between the room  
controller and the display device, tunneling through the VP-770.

To setup and activate port tunneling on the VP-770:  
1. Set the dedicated port tunneling Ethernet connection port type and port  
number through which the VP-770 will be passing RS-232 signals.  
By default, the dedicated port settings are TCP, 5050.  
To change these settings see the “Port Tunneling Configuration” in the table  
in Section 12.4.  
2. Set the HDBT UART command (the table in Section 12.4).  
By default, the settings are 9600,8,N,1  
3. Make sure that the VP-770 is connected to Ethernet.

12 The VP-770 RS-232 Communication Protocol  
The Kramer Protocol lets you control the VP-770 from any standard terminal  
software (for example, the Windows® HyperTerminal Application).  
12.1 Using the Communication Protocol  
There are three different methods to control the VP-770 via the RS-232 or the  
Ethernet:  
Protocol commands (via protocol 3000 or Legacy Protocol) mimicking the  
OSD, see Section 12.2  
The button functions mimicking the remote controller buttons (as well as the  
front panel buttons), see Section 12.3  
Protocol 3000 common commands, see Section 12.4  
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.  
i
The protocol 3000 communications protocol uses a data rate of 115200 baud, with  
no parity, 8 data bits, and 1 stop bit.  
The Legacy communication protocol uses a data rate of 9600 baud, with no parity,  
8 data bits and 1 stop bit. CTS mode and XON/XOFF are set to Off.  
Note that if the Protocol is set to Legacy (via the Miscellaneous menu,  
see Section 6.8), some PC applications (for example, K-Upload), as  
i
well as the Web pages may not function properly.  
12.2 Communication Protocol Mimicking OSD  
The audio/video protocol commands defines all the function numbers, their valid  
parameters can be used with protocol 3000 or the Legacy protocol.

12.2.1 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 window control (721) to PiP:  
Send: “#y 0,721,1”  
Reply: “~01@Y 0,721,1 OK”  
Get Command:  
Type in: “Y Control_Type=1,Function”  
Result: “~id=01Y Control_Type=1,Function,Param”  
Get command example: get window control setup (721):  
Send: “#y 1,721”  
Result: “~01@y 1,721,1”  
You can add a last parameter, to be located fourth in SET or third  
in GET, to define a specific window.  
i
For example:  
Set H Sharpness value to 10 on the PiP window (1): “#y 0,510,10,1”  
Get H sharpness of the Main window (0): “#y 1,510,0”  
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, move the PiP window one step to the left  
Send: “#Y 0,141,-,1<CR>”  
Reply: “~01@Y 0,141,-,1 OK”  
For example, in order to increase zoom on the main windows  
Send: “#Y 0,650,+,0<CR>”  
Reply: “~01@Y 0,650,+,0 OK”

12.2.2 Using the Communication Protocol with Legacy Protocol  
Set Command:  
Type in: YControl_TypeFunctionParam[CR]  
Reply: ZControl_TypeFunctionParam[CR][LF]  
Get Command:  
Type in: YControl_TypeFunction[CR]  
Reply: ZControl_TypeFunctionParam[CR][LF]  
When sending a command, a blank character may precede [CR] if desired  
Example:  
Example 1: set brightness value as 32  
Send: Y041032[CR]  
Reply: Z141032[CR][LF]  
Example 2: get current output resolution. (4 = SVGA)  
Send: Y1631[CR]

12.2.3 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 third menu on the OSD is Process (3 in the hundreds). The  
second menu item in Process is Film Mode (2 in the tens), therefore the function  
number for it will be 320 (3rd item on the Main Window Control and the 2nd item in  
the Process submenu (see also Section 6.1). When navigating in the OSD MENU  
you will be able to see the Film Mode valid parameters.  
Note that SDI is not applicable to the VP-770 and appears transparent  
in the OSD. The commands related to SDI in the protocol commands
