Introduction

Welcome to Kramer Electronics! Since 1981, Kramer Electronics has been providing a world
of unique, creative, and affordable solutions to the vast range of problems that confront the
video, audio, presentation, and broadcasting professional on a daily basis. In recent years, we
have redesigned and upgraded most of our line, making the best even better!

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.

Go to www.kramerav.com/downloads/DSP-1 to check for up-to-date user manuals,
application programs, and to check if firmware upgrades are available (where appropriate).

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 neighboring electrical appliances that may adversely influence

signal quality.

• Position your Kramer DSP‑1 away from moisture, excessive sunlight and dust.

This equipment is to be used only inside a building. It may only be connected to other
equipment that is installed inside a building.

Safety Instructions

Caution: There are no operator serviceable parts inside the unit.
Warning: Use only the Kramer Electronics power supply that is provided with the unit.
Warning: Disconnect the power and unplug the unit from the wall before installing.

Connecting DSP‑1

Always switch off the power to each device before connecting it to your DSP‑1. After
connecting your DSP‑1, connect its power and then switch on the power to each device.

Figure 2: Connecting to the DSP‑1 Rear Panel

To connect DSP‑1 as illustrated in Figure 2:

1. Connect an unbalanced stereo audio source (for example, an MP3) to the IN 1 3.5mm
mini jack .

2. Connect a balanced stereo source (for example, from a PC) to the IN 2 5-pin terminal
block connector .

3. Connect the LINE OUT 5-pin terminal block connector to a balanced stereo audio
acceptor (for example, active speakers).
Connect the left speaker to the “L+” and the “L-” terminal block connectors, and the right
speaker to the “R+” and the “R-” terminal block connectors.

Do not ground the speakers.

4. If required, connect to:

▪ A PC or serial controller via the RS-232 3-pin terminal block .
▪ A PC via the ETHERNET RJ-45 port .

5. Connect the 5V DC power connector to the power adapter and plug it to the mains
electricity.
We recommend that you use only the power adapter that is supplied with this machine.

Connecting to DSP‑1 via RS-232

You can connect to the DSP‑1 via an RS-232 connection to the RS-232 port using, for
example, a PC.

Connect the RS-232 terminal block on the rear panel of the DSP‑1 to a PC/controller, as
follows (see Figure 3):

• TX pin to Pin 2.

• RX pin to Pin 3.

• GND pin to Pin 5.

DSP‑1 – Protocol 3000

Protocol 3000

The DSP‑1 Digital Sound Processor can be operated using the Kramer Protocol 3000 serial
commands. The command framing varies according to how you interface with the DSP‑1.

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, depending 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.

Kramer Electronics Ltd.

DSP‑1 – Protocol 3000

22

For more information about Protocol 3000 commands, see:

• Understanding Protocol 3000 on page 22.

• Kramer Protocol 3000 Syntax on page 23.

• Protocol 3000 Commands on page 24.

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.

Kramer Electronics Ltd.

DSP‑1 – Protocol 3000

23

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)

• Simple Command – Command string with only one command without addressing:
