Step 5: Connect the power

Connect AC power to the rear of the VP-774A, switch on its power and then switch on the power on each device.

Step 6: Set operation parameters via OSD menu

Enter the OSD menu via the MENU button on the front panel or the IR remote control transmitter. Select a menu item and set parameters as required. Sub-menus include: Input, Audio, Process, Picture, Enhance, Scale and Misc

Note: By default the output resolution is set to Native, the VP-774A 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 you cannot see any images, verify that the display, TV, or projector is in good working order and is connected to the VP-774A. If you still don't see an image, press and hold the RESET TO XGA/720P button for 2 seconds to reset the output to XGA or 720p resolution.

3 Overview

The Kramer VP-774A is a high quality presentation switcher and scaler. It accepts one of nine inputs: an SDI signal on a BNC connector, a DisplayPort (DP) signal on a DisplayPort connector, one composite video signal on an RCA connector, two computer graphics signals on 15-pin HD connectors, and four HDMI signals on HDMI connectors. It scales the video, embeds the audio, and simultaneously outputs the signal as follows: to two HDMI outputs, to an SDI output and to an HDBaseT TP output, together with a digital audio output and a balanced stereo audio output.

The VP-774A 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
• 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-774A via the Ethernet, allowing status requests and control of the destination unit

Control your VP-774A:

• Directly, via the front panel push buttons
• By RS-232 serial commands transmitted by a touch screen system, PC, or other serial controller
• Remotely, from the infrared remote control transmitter
  • Via the Ethernet (optionally via the Web pages)

The VP-774A is housed in a 19" 1U rack mountable enclosure, with rack "ears" included, and is fed from a 100-240 VAC universal switching power supply.

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-774A 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-UNIKat (CAT 6A U/FTP cable) significantly outperforms regular CAT 5 / CAT 6 cables.

We strongly recommend that you use shielded twisted pair cable.

4 Installing in a Rack

This section provides instructions for rack mounting the unit.

Before installing in a rack, be sure that the environment is within the recommended range:

OPERATING TEMPERATURE:	0° to +40°C (32° to 104°F)
STORAGE TEMPERATURE:	-40° to +70°C (-40° to 158°F)
HUMIDITY:	10% to 90%, RHL non-condensing

CAUTION!

When installing on a 19" rack, avoid hazards by taking care that:

1. It is located within the recommended environmental conditions, as the operating ambient temperature of a closed or multi unit rack assembly may exceed the room ambient temperature.
2. Once rack mounted, enough air will still flow around the machine.
3. The machine is placed straight in the correct horizontal position.
4. You do not overload the circuit(s). When connecting the machine to the supply circuit, overloading the circuits might have a detrimental effect on overcurrent protection and supply wiring. Refer to the appropriate nameplate ratings for information. For example, for fuse replacement, see the value printed on the product label.
5. The machine is earthed (grounded) in a reliable way and is connected only to an electricity socket with grounding. Pay particular attention to situations where electricity is supplied indirectly (when the power cord is not plugged directly into the socket in the wall), for example, when using an extension cable or a power strip, and that you use only the power cord that is supplied with the machine.

To rack-mount a machine:

1. Attach both ear brackets to the machine. To do so, remove the screws from each side of the machine (3 on each side), and replace those screws through the ear brackets.

Technical line drawing of a mechanical bracket assembly with bolts and mounting holes (no text or symbols)

1. Place the ears of the machine against the rack rails, and insert the proper screws (not provided) through each of the four holes in the rack ears.

Note:

• In some models, the front panel may feature built-in rack ears
- Detachable rack ears can be removed for desktop use
• Always mount the machine in the rack before you attach any cables or connect the machine to the power
- If you are using a Kramer rack adapter kit (for a machine that is not 19"), see the Rack Adapters user manual for installation instructions available from our Web site

5 Connecting the VP-774A

Always switch off the power to each device before connecting it to your VP-774A. After connecting your VP-774A, connect its power and then switch on the power to each device.

6 The OSD Menu

The VP-774A 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 HDMI2 (see Section 6.7).

The table below shows function 632 (from the Protocol in Section 13.2):

• 6 in the hundreds, represents "Scale" which is the 6^th menu item in the main menu list
• 3 in the tens, represents "Output" which is 3^rd in the Scale menu
• 2 in the units, represents "Master Connection" which is second in the Output menu

Level 1	Level 2	Level 3	Level 4 (Function)	Range	Function
Scale (6) Output (3) Master Connection (2)			HDMI1 0 632
			HDMI2	1
			HDBT	2
			SDI	3

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 (HDMI2)

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, see Section 6.8).

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:

• A selected parameter that turns gray becomes valid immediately. You can press Enter at this point to save these parameter changes to the memory immediately (the screen will display "Saving Data" for a split second).
  • In any case, exiting the menu saves the parameter to the memory
• Data is saved per window and per input (to a dedicated input + window memory), as applicable

The control buttons let you control the VP-774A via the OSD menu. Press the:

- MENU (or ◀) button to enter the menu, exit the menu, and when in the OSD menu, move to the previous level and change menu settings in the OSD screen.

Changes are immediate

The default timeout is set to 30 seconds and can be changed (see Section 6.8)

- ENTER (or ▷) button to access sub-menu items

- Arrow buttons to move through the OSD menu

- Up or down arrows to change settings

Note that when exiting the menu, all the changes are automatically saved to the non-volatile memory.

The default OSD timeout for auto exit is set to 30 seconds and can be changed (see Section 6.8).

6.1.1 OSD Control Icons

The following three icons: M, P, and E are included to indicate when functionality applies to the Main window, the PiP Window or the entire system:

• M for Main Window Control
• P for PiP window Control
• E for Entire System Control

Figure 20: Set the Output Volume Level

6.3.1 SDI Channeling

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 Embedder/De-embedder, or the Kramer 6809HD HD/SD-SDI AES Embedder).

Within the two connected groups, one channel can be activated and the remaining three channels are bypassed. The acceptor device will input the channels as follows: the active channel is input as Group A, CH1; the bypassed channel in the same group is input as Group A, CH2; the two remaining bypassed channels are input as Group B CH1 and CH2.

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 audio acceptor:

• The group B active CH2 signal is input as Group A, CH1
• The group B bypassed CH1 signal is input as Group A CH2
• The group A bypassed CH1 signal is input as Group B CH1
• The Group A bypassed CH2 signal is input as Group B CH2

If a different channel within the connected groups is activated, the remaining three channels will be automatically routed to bypass.

If a channel in a disconnected group is activated, the system will automatically rearrange the groups and channel assignments to keep two groups connected and two others disconnected.

6.3.1.1 Bypassed Channels

Select Bypass channels to set the bypassed channels to mute to cutoff the bypassed audio channels or to Unmute to let them pass through:

	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-774A 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

Black-and-white exterior view of a grand palace with symmetrical gardens and central fountain (no visible text or signage)

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-774A 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.

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, 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-774A 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-774A 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

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.

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.oasis-open.org/committees/download.php/6334/oasis-200402-cap-core-1.0.pdf.

The VP-774A 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.

    B --> C["Dedicated EAS Ethernet Port VP-774AMP"]
    C --> D["Computer monitor with network icon"]

Figure 30: 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 (see Section 13.4).

Figure 31: 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-774A (front panel or remote control buttons, as well as via the Web page or protocol commands).

To setup and activate the alert system on the VP-774A:

1. Set the dedicated EAS Ethernet connection port type and port number through which the VP-774A 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-774A is connected to Ethernet.
3. Make sure that Alert System in the Miscellaneous menu is set to On (see Section 6.8).

The VP-774A 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 command (see Section 9.8).

7 The Display Modes

The VP-774A can function in the single window display mode (the factory default setup) or the dual window display mode.

7.1 The Single Window Display Mode

The single window mode shows one window on the screen. The window size can be customized, and its parameters modified via the OSD menu.

7.1.1 Activating the Single Window Mode

Set the VP-774A to the single window display mode in any of the following ways:

• Press and hold (for 3 seconds) the illuminated front panel PIP button until the button no longer illuminates
• Access the OSD menu, select INPUT>Display Mode, and then choose Single Window
• Access the Web pages (see Section 8.3)
• Press the PIP window on the remote control transmitter (see Section 8.4)

7.2 The Dual Window Display Mode

The VP-774A dual window mode feature lets you show two images on one screen: the main window and the PiP window. 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 dual window mode appears in the following preset PiP configurations:

Picture-in-Picture, with a smaller PiP window superimposed over a full main window image

- Last Connected mode to immediately switch to the latest valid input signal connected (for HDMI and DP inputs only) Note that in case the last connected valid input signal is disconnected, the VP-774A will switch to the previous last-connected valid-input signal, and then to the input before that and so on until the last disconnected inputs, and then a “No Signal” screen will appear

Figure 49: The Routing & Scaling Page – Auto Switching Window (Main Tab)

Figure 50: The Routing & Scaling Page – selecting the Inputs to Scan (PiP Tab)

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 (9) to the highest (1). For example, if PC 1 and HDMI 2 have a valid signal and auto switching is enabled, the VP-774A will scan through the inputs and select the HDMI 2 which is higher in the priority list (see Figure 49). Once the signal is no longer valid on HDMI 2, the VP-774A 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 51. In this example, CV is moved up in the priority list to be scanned for a valid input after HDMI 1.

The port tunneling feature lets you send and receive simple RS-232 signals between a controller and a serial device via the VP-774A which is connected to the Ethernet and outputs via TP cable.

The example, illustrated in Figure 96, shows a Kramer room controller that is connected to the VP-774A via the Ethernet. The HDBT OUT connector on the VP-774A is connected via TP to an HDBT receiver. This HDBT receiver connects to a display via HDMI and RS-232.

Figure 96: Port Tunneling

The room controller sends RS-232 signals over the Ethernet via a dedicated Tunneling port to the VP-774A. The VP-774A 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-774A.

To setup and activate port tunneling on the VP-774A:

1. Set the dedicated port tunneling Ethernet connection port type and port number through which the VP-774A 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 9.6.3).
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-774A is connected to Ethernet.

The VP-774A is now ready to tunnel RS-232 signals via Ethernet port tunneling.

11 Flash Memory Upgrade

You can upgrade the VP-774A via the Kramer K-UPLOAD software. Two types of upgrade files are available for upgrade: video core and audio/graphics (*.fct) and peripherals (*.kfw).

Note that when uploading files via K-UPLOAD, you must close the embedded Web pages.

The latest firmware version, the Flash Memory Upgrade user guide, as well as the latest version of K-UPLOAD and installation instructions can be downloaded from the Kramer Web site at www.kramerav.com/downloads/

Note that if the Protocol is set to Legacy (via the Miscellaneous menu, see Section 6.8), the Web pages may not function properly.

13 The VP-774A RS-232 Communication Protocol

The Kramer Protocol lets you control the VP-774A 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-774A via the 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.

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"

13.2.2 Using the Communication Protocol with Legacy Protocol

Set Command:

Type in: Y■Control_Type■Function■Param[CR]

Reply: Z■Control_Type■Function■Param[CR][LF]

Get Command:

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]

13.2.3 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 ( 3^rd item on the Main Window Control and the 2^nd 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:

1st Level	2nd Level	3rd Level	4th Level	Range	Func.	Note
