VP-770 - Overview

3 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 de­interlacing 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 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
up, as well as an optional audio alert

 Port tunneling, bidirectional RS-232 interface – simple control commands

and data can flow in both directions from a controller to the VP-770 via the
Ethernet, allowing status requests and control of the destination unit

If an HDMI signal is HDCP protected, it can only appear on HDMI
and DGKat outputs that are connected to HDCP compliant displays.

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.

i

3.1 HDCP Compliance

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.

6 The OSD Menu

The VP-770 OSD menu lets you set the operation parameters for the:

 Main Window Control
 PIP Window Control
 Entire System Control

The nature of the operation setup appears in the OSD title, as shown in the
example in Section 6.1:

 The title line shows the control mode (Main, PIP or Entire system)
 Level 1 lists the main menu items
 Level 2 includes the second hierarchy level, below level 1
 Level 3 includes the third hierarchy level, below level 2
 Function, is the selectable parameter or numerical value and can appear

either under level 2 or 3

6.1 OSD Menu Operation Example

In the example illustrated below, the Master Connection is set to DGKat (see

Section 6.7).

The table below shows function 632 (from the Protocol in Section 12.2):

 6 in the hundreds, represents “Scale” which is the 6th menu item in the main

menu list

 3 in the tens, represents “Output” which is 3rd in the Scale menu
 2 in the units, represents “Master Connection” which is second in the Output

menu

18

VP-770 - The OSD Menu

The subtitle, below the title line shows
the current level accessed (Scale in this
example)

After selecting Output (which is the
second Level), it appears in the subtitle

Once Master Connection is selected, the

Title changes to “Entire System Control”

indicating that the selection will affect the
entire system. The subtitle shows the
current, Level 3, selection and the menu
list shows the function (DGKat)
Note that SDI is not applicable to the
VP-770 and appears transparent.
If the transparency of the OSD menu is
set to ON this menu item will become
invisible (see Section 6.8)

If the display layout includes a PiP window, you can set the OSD menu to control
the main source window and the PIP window separately (by defining Window
Control).

General characteristics which apply to the entire system (for example, setting the
volume) are changed without needing to shift control (the title line will state: Entire
System Control).

Note that for the HDMI and DP inputs, you can either select the color depth
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.

Setting the EDID on any one of the HDMI inputs affects that
HDMI input immediately (the VP-770 automatically issues a hot­plug) 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
and PiP windows display the same input, you need to set the same input
color space value for both windows

Follow Output (This option is recommended when the HDMI output is
connected to a splitter/switcher) – to activate the HDCP per output according to
the setting of the HDMI acceptor to which it is connected; that is, if the HDMI

acceptor is not HDCP compliant, the VP-770 always outputs without HDCP and
vice versa.
Not that the VP-770 will output a green screen if the output acceptor to which it
is connected is not HDCP compliant, in the case that the video on the Main or
PiP window is HDCP encrypted.

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

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

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-770 offers four different aspect ratio settings: Follow Input, Follow Output, Best
Fit and Letterbox. Here is how each of these settings works.

34

VP-770 - 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 (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

For certain displays, the screen may flicker once for about a second
after activating or changing the luma keying setting.

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.

6.8.1 The Luma Keying Feature

The luma keying feature lets you display the PiP window (the key image) as semi­transparent 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.

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-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.

VP-770 - The OSD Menu

39

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).

8.6 Controlling the VP-770 via the REMOTE Terminal Block

Connector

The REMOTE terminal block connectors include:

 A PIP pin and a G pin which are used for toggling between the Single and

Dual window modes, and for selecting a PiP input

 Nine input pins (defined in the table below) and a G pin for selecting an input

The contact closure remote control pins operate in a similar way to the INPUT
buttons (see Section 8.1). Using the contact closure remote control (also known as
push-to-make momentary contact) you can select any of the inputs. To do so,
momentarily connect the required input pin (1 to 8) on the REMOTE terminal block
connector to the G (Ground) pin of the REMOTE terminal block connector, as

Figure 30 illustrates.

Figure 30: Connecting the Contact Closure Remote Control PINs

VP-770 - Controlling the VP-770

Use the PIP pin to:

 Toggle between the Single window display mode and the Dual window

display mode, by connecting the PIP pin and the G pin for more than 3
seconds

 Select a PIP source

To select a PIP source, connect the PIP pin to the G pin and, within 3 seconds,
momentarily connect an input pin to the G pin. For example, to select the DP PIP
source, connect the PIP pin to the G pin and, within 3 seconds, the 5 pin to the G
pin, as illustrated in Figure 31.

8.7.1 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 IRreceiver to the REMOTE IR 3.5mm connector.

VP-770 - Port Tunneling

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-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.

VP-770 - Port Tunneling

55

55

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.

The VP-770 is now ready to tunnel RS-232 signals via Ethernet port tunneling.

VP-770 - The VP-770 RS-232 Communication Protocol

61

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-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

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.

62

VP-770 - The VP-770 RS-232 Communication 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 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:

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)
Send: Y1631[CR]
Reply: Z16314[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.

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
