VP-439 - Getting Started
Go to http://www.kramerav.com/downloads/VP-439 to check for up-to-date
user manuals, application programs, and to check if firmware upgrades are
available (where appropriate).
This equipment is to be used only inside a building. It may only be
connected to other equipment that is installed inside a building.
2 Getting Started
We recommend that you:
Unpack the equipment carefully and save the original box and packaging
materials for possible future shipment
Review the contents of this user manual
2.1 Achieving the Best Performance
To achieve the best performance:
Use only good quality connection cables (we recommend Kramer high-
performance, high-resolution cables) to avoid interference, deterioration in
signal quality due to poor matching, and elevated noise levels (often
associated with low quality cables)
Do not secure the cables in tight bundles or roll the slack into tight coils
Avoid interference from neighboring electrical appliances that may adversely
influence signal quality
Position your Kramer VP-439 away from moisture, excessive sunlight and
dust

VP-439 - Overview
3 Overview
The VP−439 is a high−performance digital scaler for computer graphics video,
composite and HDMI signals, including audio. It up− or down−scales the selected
HDMI, CV or computer graphics video/YPbPr input and outputs it to HDMI.
The audio input source is selectable from Web pages– either from the relevant
analog audio input, or de-embedded from the HDMI input. The audio output can
be delayed for lip-sync compensation, and is available on the analog stereo
output, as well as being embedded onto the HDMI output.
More specifically, the VP-439 features:
HDTV compatibility and scales to resolutions up to 1080p/WUXGA
Clean and quiet auto-switching that searches for valid signal when the input
signal is lost with no video glitches or audible clicks or noises
Automatic detection and selection of the audio source for the HDMI input.
Default selection is HDMI – if this is not present, then the machine uses the
audio from the analog input
Auto-power down if no valid input signal is detected for a period of 2 to 3
minutes, the HDMI output is shut down, and the PC output syncs are disabled
HDCP enabling/disabling
Analog audio inputs for the CV, PC and HDMI inputs
Lip sync delay
An On-Screen Display (OSD) for easy setup and adjustment, accessible via
the front-panel buttons
An OSD INFO screen showing the selected input source, input and output
resolutions, HDCP status, firmware version, etc.
A built-in ProcAmp for convenient adjustment of video parameters, such as
brightness, contrast, color, sharpness and hue
A non-volatile memory that retains the last settings used
Convenient setup and control options – front panel buttons, OSD, Web page

Always switch off the power to each device before connecting it to your
VP-439. After connecting your VP-439, connect its power and then
switch on the power to each device.
4 Connecting the VP-439
To connect the VP-439 as illustrated in the example in Figure 2:
1. Connect an HDMI source (for example, from a Blu-ray player) to the HDMI
IN HDMI connector.
2. Connect a PC graphics and unbalanced stereo audio source (for example,
from a laptop PC) to the PC IN 15-pin HD and 3.5mm mini jack connectors.
3. Connect a composite video and unbalanced stereo audio source (for
example, from a DVD payer) to the CV IN RCA and LEFT/RIGHT RCA
connectors.
4. Connect the HDMI OUTPUT on a DVI-I connector and the LEFT/RIGHT
unbalanced stereo audio on two RCA connectors to an HDMI acceptor (for
example, to a display with speakers).
5. If desired, connect the ETHERNET RJ-45 connector to a control device (for
example, a PC).

Kramer Protocol 3000 commands (see Section 8.2)
Kramer Protocol 3000 detailed commands (See Section 8.3)
8.1 Kramer Protocol 3000 Syntax
Protocol 3000 communicates at a data rate of 9,600 baud, no parity, 8 data bits
and 1 stop bit.
8.1.1 Host Message Format
Simple Command
Command string with only one command without addressing:
Command String
Formal syntax with commands concatenation and addressing:
8.1.2 Device Message Format
Device Long Response
Echoing command:
CR = Carriage return (ASCII 13 = 0x0D)
LF = Line feed (ASCII 10 = 0x0A)
32
VP-439 - The RS-232/Ethernet (UDP) Communication Protocol
SP = Space (ASCII 32 = 0x20)
8.1.3 Command Terms
Command
A sequence of ASCII letters ('A'-'Z', 'a'-'z' and '-').
Command and parameters must be separated by at least one space.
Parameters
A sequence of alphameric ASCII characters ('0'-'9','A'-'Z','a'-'z' and some special
characters for specific commands). Parameters are separated by commas.
Message string
Every command entered as part of a message string begins with a message
starting character and ends with a message closing character.
Note: A string can contain more than one command. Commands are separated by
a pipe ( '|' ) character.
Message starting character
'#' – For host command/query
'~' – For machine response
Device address (Optional, for K-NET)
K-NET Device ID followed by '@'
Query sign
'?' follows some commands to define a query request.
Message closing character
CR – For host messages; carriage return (ASCII 13)
CRLF – For machine messages; carriage return (ASCII 13) + line-feed (ASCII 10)
Command chain separator character
When a message string contains more than one command, a pipe ( '|' ) character
separates each command.
Spaces between parameters or command terms are ignored.
VP-439 - The RS-232/Ethernet (UDP) Communication Protocol
33
33
8.1.4 Entering Commands
You can directly enter all commands using a terminal with ASCII communications
software, such as HyperTerminal, Hercules, etc. Connect the terminal to the serial
or Ethernet port on the Kramer device. To enter CR press the Enter key.
( LF is also sent but is ignored by command parser).
For commands sent from some non-Kramer controllers like Crestron,
some characters require special coding (such as, /X##). Refer to the
controller manual.
8.1.5 Command Forms
Some commands have short name syntax in addition to long name syntax to allow
faster typing. The response is always in long syntax.
8.1.6 Command Chaining
Multiple commands can be chained in the same string. Each command is
delimited by a pipe character ( '|' ). When chaining commands, enter the message
starting character and the message closing character only once, at the
beginning of the string and at the end.
Commands in the string do not execute until the closing character is entered.
A separate response is sent for every command in the chain.
