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

3.1 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.

Following the self-test the current switching configuration is displayed, an example
of which is shown below. The top row indicates the output port and the bottom row
indicates which input port is switched to the output port displayed directly above it.
An input port showing 0 (zero) indicates that the output port has no input switched
to it.

VS-44DT - Protocol 3000

The framing of the command varies according to the terminal
communication software.

11 Protocol 3000

The VS-44DT can be operated using the Kramer Protocol 3000 serial commands.
The command framing varies according to how you interface with the VS-44DT. For
example, a basic video input switching command that routes a layer 1 video signal
to HDMI out 1 from HDMI input 2 (ROUTE 1,1,2), is entered as follows:

 Terminal communication software, such as Hercules:

 K-Touch Builder (Kramer software):

VS-44DT - Protocol 3000

45

45

All the examples provided in this section are based on using the
K-Config software.

 K-Config (Kramer configuration software):

You can enter commands directly using terminal communication software (e.g.,
Hercules) by connecting a PC to the serial or Ethernet port on the VS-44DT. To
enter CR press the Enter key (LF is also sent but is ignored by the command
parser).

Commands sent from various non-Kramer controllers (e.g., Crestron) may require
special coding for some characters (such as, /X##). For more information, refer to
your controller’s documentation.

For more information about:

 Using Protocol 3000 commands, see Section 11.1
 General syntax used for Protocol 3000 commands, see Section 11.2
 Protocol 3000 commands available for the VS-44DT, see Section 11.3

11.1 Understanding Protocol 3000

Protocol 3000 commands are structured according to the following:

 Command – A sequence of ASCII letters (A-Z, a-z and -). A command

and its parameters must be separated by at least one space.

 Parameters – A sequence of alphanumeric 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.

46

VS-44DT - Protocol 3000

A string can contain more than one command. Commands are
separated by a pipe (|) character.

The maximum string length is 64 characters.

Spaces between parameters or command terms are ignored.
Commands in the string do not execute until the closing character is
entered. A separate response is sent for every command in the
chain.

 Message starting character:

 # – For host command/query
 ~ – For device response

 Device address – K-NET Device ID followed by @ (optional, K-NET only)
 Query sign – ? follows some commands to define a query request
 Message closing character:

 CR – Carriage return for host messages (ASCII 13)
 CR LF – Carriage return for device messages (ASCII 13) and line-feed

(ASCII 10)

 Command chain separator character – 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 at the beginning and end of the string.

11.2 Kramer Protocol 3000 Syntax

The Kramer Protocol 3000 syntax uses the following delimiters:

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

Some commands have short name syntax in addition to long name syntax to
enable faster typing. The response is always in long syntax.

The Protocol 3000 syntax is in the following format:

Description

Syntax

Set:

the input EEPROM

#CPEDIDSP src_type,src_id,dst_type,
dest_bitmapCR

Get: - -

Response

~nn @CPEDID SPsrc_type,src_id,dst_type,dest_bitmap CR LF

Parameters

src_type – EDID source type: IN=0, OUT=1, default EDID=2
src_id – IN=1~4, OUT=1~4
dst_type –input=0
dest_bitmap – bitmap representing destination IDs. Format: XXXX…X, where X is hex digit. The binary

form of every hex digit represents corresponding destinations. Setting ‘1’ indicates that EDID data is
copied to this destination. Setting ‘0’ indicates that EDID data is not copied to this destination.

Response Triggers

Response is sent to the com port from which the Set was received (before execution)

Notes

Destination bitmap size depends on device properties (for 64 inputs it is a 64-bit word)
Example: bitmap 0x0013 means inputs 1, 2 and 5 are loaded with the new EDID.
In this device, if the destination type is input (0), the bitmap size is 4 bits, for example bitmap 0x5 means

inputs 1 and 3 are loaded with the new EDID.

K-Config Example

Copy the EDID data from the HDMI Out 1 output (EDID source) to the HDMI In 1 input:

“#CPEDID 1,1,0,0x1”,0x0D

Copy the EDID data from the default EDID source to HDMI In 1 and HDMI In 2:
“#CPEDID 2,0,0,0x3”,0x0D

11.4.3 EDID Handling Commands

Additional EDID data functions can be performed via the VS-44DT web pages or a
compatible EDID management application, such as Kramer EDID Designer (see

Response

~nn @NET-DHCP SPmode CR LF

Parameters

mode – 0 (do not use DHCP. Use the IP address set by the factory or the NET-IP command), 1 (try to
use DHCP. If unavailable, use the IP address set by the factory or the NET-IP command)

Notes

Connecting Ethernet to devices with DHCP may take more time in some networks
To connect with a randomly assigned IP by DHCP, specify the device DNS name (if available) using the
NAME command. You can also get an assigned IP by direct connection to USB or RS-232 protocol port if
available
Consult your network administrator for correct settings
