VSM-4x4HFS - Getting Started

Go to http://www.kramerav.com/downloads/VSM-4x4HFS to check for up-
to-date user manuals, application programs, and to check if firmware
upgrades are available (where appropriate).

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

2 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

2.1 Achieving the Best Performance

To achieve 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 neighbouring electrical appliances that may adversely

influence signal quality

 Position your Kramer VSM-4x4HFS away from moisture, excessive sunlight

and dust

Always switch off the power to each device before connecting it to
your VSM-4x4HFS. After connecting your VSM-4x4HFS, connect its
power and then switch on the power to each device.

You do not have to connect all the inputs and outputs, connect only
those that are required.

5 Connecting and Operating the VSM-4x4HFS

The VSM-4x4HFS is a four-in-one-box device. It can operate as a:

 Matrix switcher
 Video wall
 Dual switcher
 Quad switcher

You can select the different operation modes via front panel buttons, the IR remote
control transmitter, the OSD menu or via the Web pages.

This section describes how to connect and operate the VSM-4x4HFS for operating
in each of the four operation modes (see Section 5).

5.1 The Matrix Mode

The VSM-4x4HFS matrix switcher mode is the default operation mode. Any of the
four inputs can be switched to any of the four outputs. Switching is immediate and
seamless.

5.1.1 Connecting the VSM-4x4HFS in the Matrix Operation Mode

To connect the VSM-4x4HFS in the MATRIX mode, as illustrated in the example in

Figure 3, do the following:

1. Connect up to four HDMI sources (for example, laptops and/or Blu-ray disk
players) to the HDMI INPUT connectors (from INPUT 1 to INPUT 4).

10

VSM-4x4HFS - Connecting and Operating the VSM-4x4HFS

2. Connect the four HDMI OUTPUT connectors (from OUTPUT A to OUTPUT
D) to up to four HDMI acceptors (for example, LCD displays and/or
projectors).

3. Connect the power cord (not shown in Figure 3).

4. If required, connect:

 A PC via RS-232, see Section 6.3

The video wall mode lets you display the output on a set of four monitors /
projectors / TV sets that are tiled together in a 2x2 setting to form one large display.
Each output shows one quarter of the image as shown in the example in Figure 4.
In the video wall mode the audio of the selected input is routed to one of the
outputs.

button to simultaneously activate the multiple switches

 Every action requires user confirmation which protects against erroneous

switching

 Execution is delayed until the user confirms the action

Note that if the TAKE button is not pressed within 60 seconds, this action is aborted

10 The VSM-4x4HFS RS-232/Ethernet (UDP)

Communication Protocol

The VSM-4x4HFS can be operated using serial commands from a PC, remote
controller, or touch screen. The unit communicates using the default Kramer
Protocol 3000.

10.1 Protocol 3000

 Kramer Protocol 3000 syntax (see section 10.1.1)
 Kramer Protocol 3000 commands (see section 10.1.2)

10.1.1 Kramer Protocol 3000 Syntax

Protocol 3000 communicates at a data rate of 115200 baud, no parity, 8 data bits
and 1 stop bit.

10.1.1.1 Host Message Format

Simple Command

Command string with only one command without addressing:

Formal syntax with commands concatenation and addressing:

10.1.1.2 Device Message Format

Device Long Response

Echoing command:

CR = Carriage return (ASCII 13 = 0x0D)
LF = Line feed (ASCII 10 = 0x0A)
SP = Space (ASCII 32 = 0x20)

10.1.1.3 Command Terms

Command

A sequence of ASCII letters ('A'-'Z', 'a'-'z' and '-').
Command and parameters must be separated by at least one space.

Parameters
A sequence of alphameric 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.
Note: A string can contain more than one command. Commands are separated by

a pipe ( '|' ) character.

Message starting character
'#' – For host command/query
'~' – For machine response

Device address (Optional, for K-NET)
K-NET Device ID followed by '@'

VSM-4x4HFS - The VSM-4x4HFS RS-232/Ethernet (UDP) Communication Protocol

61

61

Query sign
'?' follows some commands to define a query request.

Message closing character
CR – For host messages; carriage return (ASCII 13)
CRLF – For machine messages; carriage return (ASCII 13) + line-feed (ASCII 10)

Command chain separator character
When a message string contains more than one command, a pipe ( '|' ) character
separates each command.

Spaces between parameters or command terms are ignored.

10.1.1.4 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
or Ethernet 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.

10.1.1.5 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.

10.1.1.6 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.

Commands in the string do not execute until the closing character is entered.
A separate response is sent for every command in the chain.

10.1.1.7 Maximum String Length

64 characters
