Getting Started
Achieving the Best Performance
To achieve the best performance:
2.1
•
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 910 away from moisture, excessive sunlight
and dust
This equipment is to be used only inside a building. It may be
connected only to other equipment that is installed inside a building.
!
2.2
Safety Instructions
Caution:
No operator serviceable parts inside the unit
!
Warning: Use only the Kramer Electronics input power wall
adapter that is provided with the unit.
Warning: Disconnect the power and unplug the unit from the wall
before installing
2.3
Recycling Kramer Products
The Waste Electrical and Electronic Equipment (WEEE) Directive
2002/96/EC aims to reduce the amount of WEEE sent for disposal to
landfill or incineration by requiring it to be collected and recycled. To
comply with the WEEE Directive, Kramer Electronics has made
arrangements with the European Advanced Recycling Network (EARN)
and will cover any costs of treatment, recycling and recovery of waste

The 910 has the following features:
•
Grouped audio controls: volume, balance, bass, mid, treble,
loudness, equalizer, delay, mute, expand and compress
•
Selectable condenser or dynamic mic input with talk over, mix and
override controls
•
•
A 24-character by 2-line LCD display
Memory locations that store up to 4 presets to be recalled and
executed when needed
•
•
A USB port for software upgrades
Flexible control options including the front panel, RS-232 (with
Windows®-based control software included), Ethernet and IR
•
Standard 19” rack mount size of 1U with rack "ears" included
To achieve the best performance:
•
deterioration in signal quality due to poor matching, and elevated
noise levels (often associated with low quality cables).
•
Avoid interference from neighboring electrical appliances that may
adversely influence signal quality and position your Kramer 910
away from moisture, excessive sunlight and dust

KRAMER: SIMPLE CREATIVE TECHNOLOGY
910 Commands in Protocol 3000
Message starting character
'#' – For host command/query
'~' – For machine response
Device address (Optional, for K-NET)

Command chain separator character
When a message string contains more then one command, a pipe ( '|' )
character separates each command.
Spaces between parameters or command terms are ignored.
10.11 Entering Commands
You can directly enter all commands using a terminal with ASCII
communications software, such as HyperTerminal, Hercules, etc. Connect
the terminal to the serial, Ethernet, or USB port on the Kramer device. To
enter CR , press the Enter key.
( LF is also sent but is ignored by command parser).
For commands sent from some non-Kramer controllers like Crestron, some
characters require special coding (such as, /X##). Refer to the controller
manual.
10.12 Command Forms
Some commands have short name syntax in addition to long name syntax to
allow faster typing. The response is always in long syntax.
10.13 Command Chaining
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 once,
at the beginning of the string and at the end.
25
910 Commands in Protocol 3000
Commands in the string do not execute until the closing character is
entered.
A separate response is sent for every command in the chain.
10.14 Maximum String Length
64 characters
10.15 Backward Support
Protocol 2000 is transparently supported by Protocol 3000. You can switch
between protocols using a switch protocol command from either platform.
