Overview
The Kramer VP-773A is a high quality presentation switcher and scaler. It accepts
one of eight inputs: a DisplayPort (DP) signal on a DisplayPort connector, one
composite video signal on an RCA connector, two computer graphics signals on 15pin HD connectors, and four HDMI signals on HDMI connectors. It scales the video,
embeds the audio, and simultaneously outputs the signal to two HDMI outputs and
to an HDBaseT TP output, together with a digital audio output and a balanced
stereo audio output.
The VP-773A 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 deinterlacing, noise reduction, and scaling performance for both standarddefinition and high-definition signals



K-IIT XL™ Picture-in-Picture Image Insertion Technology - Ultra stable
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



An emergency alert system that can have a national or campus-wide
notification immediately displayed when an emergency situation develops, by
means of automatic text overlaying, either via a crawler or a full screen cover

VP-773A - Overview

3.1

HDCP Compliance
If an HDMI signal is HDCP protected, it can only appear on HDMI and
HDBaseT outputs that are connected to HDCP compliant displays.
The VP-773A will not output an HDCP protected source to a display that
is not HDCP compliant. Instead it will show a green 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 green.

3.2

About HDBaseT™ Technology
HDBaseT™ is an advanced all-in-one connectivity technology (supported by the
HDBaseT Alliance). It is particularly suitable in the ProAV – and also the home –
environment as a digital networking alternative, where it enables you to replace
numerous cables and connectors by a single LAN cable used to transmit, for
example, uncompressed full high-definition video, audio, IR, as well as various
control signals.
The products described in this user manual are HDBaseT certified.

3.3

Using Twisted Pair Cable
Kramer engineers have developed special twisted pair cables to best match our
digital twisted pair products; BC−HDKat6a (CAT 6 23 AWG cable) significantly
outperforms regular CAT 5 / CAT 6 cables.
We strongly recommend that you use shielded twisted pair cable.

Note that any change in the output resolution will cancel the zoom setting.

6.7.1

Selecting the Correct Aspect Ratio
You can configure the aspect ratio of any output image to fit your application. The
VP-773A 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-773A output
signal. This may result in some distortion to the input
signal images

VP-773A - The OSD Menu

33

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. When not using a 4:3
monitor, this mode is identical to Best Fit.

6.7.2

Master Connection Settings
The Master Connection (HDMI1, HDMI2 or HDBT) 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-773A is triggered to read the
EDID of the main display and change the output resolution value according to the
native resolution of the display.
If HDMI/HDBT is selected as the Master Connection, and a new display is
connected to the Master Connection output (hot plug), the VP-773A 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 is an easy-to-use method of compositing two video
sources into a single image. By setting up a “key” image or clip on a black
background, it can be merged – or overlaid – onto the primary video. The key
image is transparent in the areas of its dark background, resulting in a picture which
looks as if the key image is cut out and pasted over the primary image. This useful
function of combining images from two different sources is suitable for many
applications, such as sub-titling, labeling, advertising or logo insertion.
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 it is recommended to 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.
We recommend that you activate luma keying 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.

6.8.2

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.oasisopen.org/committees/download.php/6334/oasis-200402-cap-core1.0.pdf.
The VP-773A 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.

38

VP-773A - The OSD Menu

Figure 26: 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 a 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 (Section 13.4).

Figure 27: 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-773A (front panel or remote control buttons, as well as via the Web
page or protocol commands).

VP-773A - The OSD Menu

39

To setup and activate the alert system on the VP-773A:
1. Set the dedicated EAS Ethernet connection port type and port number
through which the VP-773A will be listening, as a client, to intercept alerts.
By default, the dedicated EAS port settings are TCP, 5005. To change these
setting see the “Emergency Alert Configuration” in the table in Section 13.4.
2. Make sure that the VP-773A is connected to Ethernet.
3. Make sure that Alert System in the Miscellaneous menu is set to On (see
Section 6.8).
The VP-773A is now ready to receive any alert and display it.
Note that you can use the Emergency Alert System Web page to connect to an EAS
server and create a local message (see Section 9.8).

When Scan mode is activated, the system scans the inputs from the highest to the
lowest priority in search of a valid input signal for each the Main and PiP windows.
The priority is ordered from the lowest input number (8) to the highest (1). For
example, if PC 1 and HDMI 2 have a valid signal and auto switching is enabled, the
VP-773A will scan through the inputs and select the HDMI 2 which is higher in the
priority list (see Figure 45). Once the signal is no longer valid on HDMI 2, the
VP-773A will scan for the next highest-priority valid signal.
Note that you can Check/uncheck the box next to an input to include/exclude it from
the input scan list.
You can change the priority order as well by dragging an input button and dropping
it in a new location, as illustrated in the example in Figure 47. In this example, CV is
moved up in the priority list to be scanned for a valid input after HDMI 1.

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-773A which is connected to the
Ethernet and outputs via TP cable.
The example, illustrated in Figure 92, shows a Kramer room controller that is
connected to the VP-773A via the Ethernet. The HDBT OUT connector on the
VP-773A is connected via TP to an HDBT receiver. This HDBT receiver connects to a
display via HDMI and RS-232.

Figure 92: Port Tunneling

The room controller sends RS-232 signals over the Ethernet via a dedicated
Tunneling port to the VP-773A. The VP-773A 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-773A.

VP-773A - Port Tunneling

91

To setup and activate port tunneling on the VP-773A:
1. Set the dedicated port tunneling Ethernet connection port type and port
number through which the VP-773A 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 13.4 or via the embedded Web pages (see Section 9.7).
2. Set the HDBT UART command (the table in Section 13.4).
By default, the settings are 9600,8,N,1
3. Make sure that the VP-773A is connected to Ethernet.
The VP-773A is now ready to tunnel RS-232 signals via Ethernet port tunneling.

VP-773A - Technical Specifications

The VP-773A RS-232 Communication
Protocol
The Kramer Protocol lets you control the VP-773A from any standard terminal
software (for example, the Windows® HyperTerminal Application).

13.1

Using the Communication Protocol
There are three different methods to control the VP-773A RS-232 or the Ethernet:


Protocol commands (via protocol 3000 or Legacy Protocol) mimicking the
OSD, see Section 13.2



The button functions mimicking the remote controller buttons (as well as the
front panel buttons), see Section 13.3



Protocol 3000 common commands, see Section 13.4
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.
Commands that are specific for the Web pages, appear in the relevant
Web page section, see the Audio Settings protocol commands in
Section 9.6.3.

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 well
as the Web pages may not function properly.

13.2

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.

VP-773A - The VP-773A RS-232 Communication Protocol

13.2.1

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.
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”
Reply: “~01@Y 0,141,-,1 OK”
For example, in order to increase zoom on the main window
Send: “#Y 0,650,+,0”
Reply: “~01@Y 0,650,+,0 OK”

Reply: ZControl_TypeFunctionParam[CR][LF]
Get Command:
Type in: YControl_TypeFunction[CR]
Reply: ZControl_TypeFunctionParam[CR][LF]
When sending a command, a blank character may precede [CR] if desired

Example:
Example 1: set brightness value as 32
Send: Y041032[CR]
Reply: Z141032[CR][LF]
Example 2: get current output resolution. (4 = SVGA)

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. The following table defines
the protocol commands:

Note that the color depth bit is the MSB of PM.EDID_SEL (which represents the resolution).
In case 8bpp is selected, set the color depth bit accordingly.
For example, when selecting 1600x900@60 at 8bpp, PM.EDID_SEL = 86h=134 dec;
and when selecting it at 12bpp, PM.EDID_SEL = 6h=6 dec
Also note that the modeline bit is bit 6 of PM.EDID_SEL (which represents the resolution). In
case single modeline is selected, set the modeline bit accordingly.
For example, when selecting 1600x900@60 in Single modeline (12bpp), PM.EDID_SEL =
46h=70 dec; and when selecting it in Multiple modelines (12bpp) , PM.EDID_SEL = 6h=6
