VP-774 – Overview
7
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-774 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.
The products described in this user manual are HDBaseT certified.
We strongly recommend that you use shielded twisted pair cable.

3.1 HDCP Compliance
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 consumer home environment as
a digital home 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.
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.

SDI channeling includes four groups with two stereo channels each. Two of the
groups are always connected and the other two disconnected. You can select (via
the OSD) one of the eight SDI embedded stereo audio channels, together with
three bypassed channels, to be routed to the input of a connected machine with
SDI audio channels (for example, the Kramer 6810HDXL SDI/HD−SDI/3G Audio

In the example illustrated in Figure 21, channels C and D are disconnected and
channels A and B are connected (CH1 and CH2 in group A are bypassed, CH1 in
group B is bypassed and CH2 in group B is active).
These channels are input to the Kramer 6810HDXL, processed and output to an

signal images
i
i
6.7.1 Selecting the Correct Aspect Ratio
You can configure the aspect ratio of any output image to fit your application. The
VP-774 offers four different aspect ratio settings: Follow Input, Follow Output, Best
Fit and Letterbox. Here is how each of these settings works.
38
VP-774 - The OSD Menu
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 (HDMI1, HDMI2, HDBT or SDI) 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-774 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:
Selecting SDI as the Master Connection results in an output resolution of
720p @60
If SDI is selected as the Master Connection, hot plugging the HDMI/HDBT
output will not change the output resolution
If HDMI/HDBT is selected as the Master Connection, and a new display is
connected to the Master Connection output (hot plug), the VP-774
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

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

6.8.1 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.

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.
The VP-774 intercepts XML files over the Ethernet in the CAP format via the

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 (see Section 12.4).

VP-774 - Controlling the VP-774
8.4.1 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 IRreceiver to the REMOTE IR 3.5mm connector.
VP-774 - Port Tunneling
57
57
9 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-774 which is connected to the
Ethernet and outputs via TP cable.
The example, illustrated in Figure 37, shows a Kramer room controller that is
connected to the VP-774 via the Ethernet. The HDBT OUT connector on the VP-774
is connected via TP to an HDBT receiver. This HDBT receiver connects to a display
via HDMI and RS-232.
Figure 37: Port Tunneling
The room controller sends RS-232 signals over the Ethernet via a dedicated
Tunneling port to the VP-774. The VP-774 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-774.
58
VP-774 - Port Tunneling
To setup and activate port tunneling on the VP-774:
1. Set the dedicated port tunneling Ethernet connection port type and port
number through which the VP-774 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-774 is connected to Ethernet.
The VP-774 is now ready to tunnel RS-232 signals via Ethernet port tunneling.

VP-774 - The VP-774 RS-232 Communication Protocol
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.
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.

12 The VP-774 RS-232 Communication Protocol
The Kramer Protocol lets you control the VP-774 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-774 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
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.
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.

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”
i
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”
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 window
Send: “#Y 0,650,+,0<CR>”
Reply: “~01@Y 0,650,+,0 OK”

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]
Reply: Z16314[CR][LF]
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. The following table defines
the protocol commands:

Note; In case 8bpp is selected, set the color depth bit accordingly.
The color depth bit is the MSB of PM.EDID_SEL (which represents the resolution).
For example, when selecting 1600x900@60 at:
8bpp, PM.EDID_SEL = 86h=134 dec
12bpp, PM.EDID_SEL = 6h=6 dec
