DIP-31 - Principles of Operation

11

In both last connected and priority modes, manually selecting an
input (using the remote input selection switches or any of the above
methods) overrides automatic selection.

6 Principles of Operation

The DIP-31 selects video and audio inputs based on the rules described below.

6.1 Input Selection

The video mode selection is set by the DIP-switches (see Section 8.1) to either of
the following modes:

 Manual
 Auto—Last connected or priority mode

In manual mode switching occurs whether or not there is a live signal present on
the input. You select manually select an input using any of the following methods:

 Front panel buttons
 Remote input selection switches
 RS-232 control
 Web pages

In auto mode, the switching selection is performed based on either last connected
or priority input.

In last connected mode, if the signal on the current input is lost, the DIP-31
automatically selects the last connected input, (the delay depending on the
configurable signal-lost timeout).

In priority mode, when the input sync signal is lost for any reason, the input with a
live signal and next in priority is selected automatically, (the delay depending on the
configurable signal-lost timeout). This priority is configurable; the default setting is
HDMI 1  HDMI 2  PC.

12

DIP-31 - Principles of Operation

Analog audio is not output when there is no display connected. If a
display is connected analog audio is output even in the absence of a
video signal.

6.2 Signal Loss and Unplugged Cable Timeouts

In both last connected and priority modes, when the input signal sync is lost (but the
cable is not removed) there is a default delay (ten seconds for video, not applicable
to the PC input, and five seconds for analog audio) before another input is
automatically selected. When an input cable is removed, there is a delay before
automatic switching takes place.

Both timeouts are configurable, (see Section 8.1).

6.3 Audio Signal Control

The Option DIP-switches 3 and 4 (see Section 8.1) control the manner in which
audio is handled.

The following table describes which audio signal is embedded in the output.

When there is an audio signal but no video signal the output is a black video pattern
in conjunction with the analog audio signal.

DIP-31 - Principles of Operation

13

6.4 VGA Phase Shift

To minimize phase on the input VGA signal, the VGA sampling phase can be
shifted using the following methods:

 A long press on the PC IN select button on the front panel.

Each long press steps the phase shift up one step, starting from 0 and going to

31. When set to 31, another long press steps the shift to 0

 A remote, contact-closure switch connected to pins 1 and G of the Remote

terminal block.
Each long press steps the phase shift up one step, starting from 0 and going to

31. When set to 31, another long press steps the shift to 0

 Using the Web pages, (see Section 0)
 Protocol 3000 commands over RS-232 (see Section 12)

14

DIP-31 - Operating the DIP-31

DIP-31 - Protocol 3000

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

12 Protocol 3000

The DIP-31 Automatic Video Switcher can be operated using the Kramer
Protocol 3000 serial commands. The command framing varies according to how
you interface with the DIP-31. 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):

DIP-31 - Protocol 3000

41

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 DIP-31. 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 12.1
 General syntax used for Protocol 3000 commands, see Section 12.2
 Protocol 3000 commands available for the DIP-31, see Section 12.3

12.1 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.

42

DIP-31 - 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.

12.2 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:

 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:

#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 (usually output): 0 (input), 1 (output), 2 (default EDID)
src_id – for input source: 1 (HDMI In 1), 2 (HDMI In 2), 3 (PC In), for output source: 1 (HDMI Out), for

default EDID source: 0 (default EDID)

dst_type – EDID destination type (usually input): 0 (input), 1 (output), 2 (default EDID)
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 3 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 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 PC In inputs:
“#CPEDID 2,0,0,0x5”,0x0D

12.3.7 EDID Handling Commands

Additional EDID data functions can be performed via the DIP-31 web pages or a
compatible EDID management application, such as Kramer EDID Designer (see
