Installing in a Rack
This section provides instructions for rack mounting the VS-44UHDA. Before installing in a
rack, verify that the environment is within the recommended range:
• Operation 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.
When installing on a 19" rack, avoid hazards by taking care that:
•
It is located within recommended environmental conditions. Operating ambient
temperature of a closed or multi-unit rack assembly may exceed ambient room
temperature.
•
Once rack mounted, there is enough air still flow around the VS-44UHDA.
•
The VS-44UHDA is placed upright in the correct horizontal position.
•
You do not overload the circuit(s). When connecting the VS-44UHDA to the supply
circuit, overloading the circuits may 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.
•
The VS-44UHDA is earthed (grounded) and connected only to an electricity socket with
grounding. Pay particular attention when electricity is supplied indirectly (for example,
when the power cord is not plugged directly into the wall socket but to an extension
cable or power strip). Use only the supplied power cord.
To rack-mount the VS-44UHDA:
1. Attach both ear brackets to the VS-44UHDA:
Remove the screws from each side of the
VS-44UHDA (3 on each side), and replace them
through the ear brackets.
2. Place the ears of the VS-44UHDA against the rack
rails and insert the appropriate screws (not provided)
through each of the four holes in the rack ears.
Some models, may feature built-in rack ears:
•

Protocol 3000
The VS-44UHDA 4x4 UHD Matrix Switcher can be operated using the Kramer Protocol 3000
serial commands. The command framing varies according to how you interface with the
VS-44UHDA.
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:
The framing of the command varies according to the terminal communication software.
.
• K-Touch Builder (Kramer software):
• K-Config (Kramer configuration software):
All the examples provided in this section are based on using the K-Config 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-44UHDA. 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.
VS-44UHDA - Protocol 3000

Kramer Electronics Ltd.
For more information about Protocol 3000 commands, see:
• Understanding Protocol 3000 on page 56
• Kramer Protocol 3000 Syntax on page 57
• Protocol 3000 Commands on page 58
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.
A string can contain more than one command. Commands are separated by a pipe (|)
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.
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.
VS-44UHDA - Protocol 3000
56
Kramer Electronics Ltd.
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:
Start
#
Address
(optional)
Device_id@
Body
Delimiter
Message
CR
• Simple Command – Command string with only one command without addressing:

to the input EEPROM
Get:
Response
~nn@CPEDIDSPsrc_type,src_id,dst_type,dest_bitmapCR LF
Set:
Parameters
src_type – EDID source type (usually output): 0 (Input), 1 (Output), 2 (Default EDID)
src_id – for input source: 1 (Input), for output source: 0 (Default EDID source), 1 (Output 1), 2 (Output 2)
dst_type – EDID destination type (usually input): 0 (input)
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 8 bit, for example bitmap 0x81 means the
inputs 1 and 8 are loaded with the new EDID.
K-Config Example
Copy the EDID data from the Output 1 (EDID source) to the Input:
“#CPEDID 1,1,0,0x1”,0x0D
Copy the EDID data from the default EDID source to the Input:
“#CPEDID 2,0,0,0x1”,0x0D
