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

Kramer Protocol 3000 Syntax

Protocol 3000 communicates at a data rate of 9,600 baud, no parity, 8 data bits and 1 stop bit.

Host Message Format

Start	Address (optional)	Body	Delimiter
#	Destination_id@	Message	CR

Simple Command

Command string with only one command without addressing:

Start	Body			Delimiter
#	Command	SP	Parameter_1,Parameter_2,...	CR

Command String

Formal syntax with commands concatenation and addressing:

Start	Address	Body	Delimiter
#	Destination_id@	Command_1 Parameter1_1,Parameter1_2,...|Command_2 Parameter2_1,Parameter2_2,...|Command_3 Parameter3_1,Parameter3_2,...|...	CR

Device Message Format

Start	Address (optional)	Body	Delimiter
~	Sender_id@	Message	CR LF

Device Long Response

Echoing command:

Start	Address (optional)	Body					Delimiter
~	Sender_id@	Command SP [Param1,Param2...] result					CR LF

• CR = Carriage return (ASCII 13 = 0x0D)
• LF = Line feed (ASCII 10 = 0x0A)
• SP = Space (ASCII 32 = 0x20)

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.

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.

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.

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.

Maximum String Length

64 characters
