Support audio only can be used if the video and audio signals routed to an output, come
from separate sources.

If Support audio only is set to:

 ON – The audio signal routed to the output remains active when the video source

(coming from a different input) is deactivated.

 OFF – The audio signal routed to the output is deactivated together with the

deactivation of the video source (coming from a different input).

The adjustment sequence presented here is only an example. You can adjust the output
settings in any other order.

If the video is lost when in the auto switching mode (Priority or Last connected) you can set
the time the device waits before it switches to the next source.

To set the video lost timer (when in auto-switching mode):

1. In the Navigation pane, click Timeout Settings. The Timeout Settings page appears.

VS-88UHDA - Protocol 3000

57

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 VS-88UHDA 8x8 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-88UHDA.

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 the VS-88UHDA. 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.

Kramer Electronics Ltd.

VS-88UHDA - Protocol 3000

58

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 58
 Kramer Protocol 3000 Syntax on page 59
 Protocol 3000 Commands on page 60

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:

Description

Syntax

Set:

#CPEDIDSPsrc_type,src_id,dst_type,dest_bitmapCR

Get: - -

Response

~nn@CPEDIDSPsrc_type,src_id,dst_type,dest_bitmapCR LF

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

EDID Handling Commands

Additional EDID data functions can be performed via a compatible EDID management
application, such as Kramer EDID Designer (see
