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.
Achieving 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 neighbouring electrical appliances that may adversely influence
signal quality.
Position your Kramer VP-428H2 away from moisture, excessive sunlight and dust.

Overview
Congratulations on purchasing your Kramer VP-428H2 4K HDBT Transmitter/Scaler.
VP-428H2 is an HDBaseT 4K transmitter/scaler with HDMI, DP and VGA inputs. VP-428H2
supports HDBT tunneling of Ethernet, bidirectional RS-232 and IR signals, as well as PoE to
provide power to the HDBaseT receiver. It receives the selected AV signal, up-scales,
down-scales or bypasses the video, according to the settings selected by the user, and
converts it for sending via HDBaseT, together with the tunneled data and PoE.
VP-428H2 is housed in a compact, Kramer MegaTOOL™ enclosure which can be mounted
side by side in a 19-inch rack using the RK-T2B rack adapter.
VP-428H2 provides exceptional quality, advanced and user-friendly operation, and flexible
control.
Functionality
Supports scaling to / from all input and output resolutions.
Works with any HDBT receiver (supports 4K without the need for a specialized receiver).
Upscales to all popular 4K resolutions (to 4K60 4:2:0 max).
Downscales from 4K60 4:4:4 to all resolutions.
Automatically downscales 6G 4K color space to 4:2:0.
4K resolution bypass option, supporting HDR.
HDBT tunnelling of RS-232, IR and Ethernet.

VP-428H2 - Protocol 3000
18
The framing of the command varies according to the terminal communication software.
.
All the examples provided in this section are based on using the K-Config software.
Protocol 3000
The VP-428H2 4K HDBT Transmitter/Scaler can be operated using the Kramer
Protocol 3000 serial commands. The command framing varies according to how you interface
with the VP-428H2.
Generally, 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):
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 your device. 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.
Page 21
Kramer Electronics Ltd.
VP-428H2 - Protocol 3000
19
A string can contain more than one command. Commands are separated by a pipe (|)
character.
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.
For more information about Protocol 3000 commands, see:
Understanding Protocol 3000 on page 19.
Kramer Protocol 3000 Syntax on page 20.
Protocol 3000 Commands on page 21.
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.
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.

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:
Host Message Format:
Simple Command – Command string with only one command without addressing:
Command String – Formal syntax with command concatenation and addressing:
Device Message Format:
Device Long Response – Echoing command:

pending – button LED flashing
The Step-in master uses this command to get the actual status and identify if the device is in pending Stepin request.
In reply to the Step-in request, the Step-in master updates the button status by sending set to activate and
configures the Step-in action. Other Step-in clients are set to mute.

After execution, response is sent to the com port from which the Set /Get was received
After execution, response is sent to all com ports if VID-RES was set by any other external control
device (button press, device menu and similar)
Notes
1. The “Set” command is only applicable when stage = 1 (Output)
2. The “Set” command with is_native = 1 (On), sets the native resolution on the selected output
(resolution index sent = 0). The device sends as an answer the actual VIC ID of native resolution.
3. The “Get” command with is_native = 1 (On) returns the native resolution VIC;
when is_native = 1 (Off), it returns the current resolution
