4 Installing in a Rack

This section provides instructions for rack mounting the unit.

Before installing in a rack, be sure that the environment is within the recommended range:

OPERATING TEMPERATURE:	0° to +40°C (32° to 104°F)
STORAGE TEMPERATURE:	-40° to +70°C (-40° to 158°F)
HUMIDITY:	10% to 90%, RHL non-condensing

CAUTION!

When installing on a 19" rack, avoid hazards by taking care that:

1. It is located within the recommended environmental conditions, as the operating ambient temperature of a closed or multi unit rack assembly may exceed the room ambient temperature.
2. Once rack mounted, enough air will still flow around the machine.
3. The machine is placed straight in the correct horizontal position.
4. You do not overload the circuit(s). When connecting the machine to the supply circuit, overloading the circuits might have a detrimental effect on overcurrent protection and supply wiring. Refer to the appropriate nameplate ratings for information. For example, for fuse replacement, see the value printed on the product label.
5. The machine is earthed (grounded) in a reliable way and is connected only to an electricity socket with grounding. Pay particular attention to situations where electricity is supplied indirectly (when the power cord is not plugged directly into the socket in the wall), for example, when using an extension cable or a power strip, and that you use only the power cord that is supplied with the machine.

To rack-mount a machine:

1. Attach both ear brackets to the machine. To do so, remove the screws from each side of the machine (3 on each side), and replace those screws through the ear brackets.

1. Place the ears of the machine against the rack rails, and insert the proper screws (not provided) through each of the four holes in the rack ears.

Note:

• In some models, the front panel may feature built-in rack ears
- Detachable rack ears can be removed for desktop use
• Always mount the machine in the rack before you attach any cables or connect the machine to the power
- If you are using a Kramer rack adapter kit (for a machine that is not 19"), see the Rack Adapters user manual for installation instructions available from our Web site

10 VSM-4x4A RS-232/Ethernet Communication Protocol

The VSM-4x4A 4x4 Seamless AV Matrix Switcher/Multi-Scaler can be operated using the Kramer Protocol 3000 serial commands. The command framing varies according to how you interface with the VSM-4x4A. In the following example, a basic video input switching command that routes a layer 1 video signal to HDBT 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. This command is used for demonstration purposes only and its syntax may vary per device.

• K-Touch Builder (Kramer software):

• K-Config (Kramer configuration software):

Command Syntax

Display Command as ○ Hex ○ Decimal ◎ ASCII

"#ROUTE 1,1,2",0x0D

Set Clear

All the examples provided in this section are based on using the Kramer 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 on the VSM-4x4A. 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 10.1
- General syntax used for Protocol 3000 commands, see Section 10.2
- Protocol 3000 commands available for the VSM-4x4A, see Section 10.3

10.1 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

A string can contain more than one command. Commands are separated by a pipe ( | ) character.

The maximum string length is 64 characters.

• 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 (1). 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.

10.2 Kramer Protocol 3000 Syntax

The Kramer Protocol 3000 syntax uses the following delimiters:

• CR = Carriage return (ASCII 13 = 0x0D)
- L _F = 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)	Body	Delimiter
#	Device_id@	Message	CR

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

Start	Body	Delimiter
#	Command SP Parameter_1,Parameter_2,...	CR

Command String – Formal syntax with command concatenation and addressing:

Start	Address	Body	Delimiter
#	Device_id@	Command_1 Parameter1_1,Parameter1_2,...|Command_2 Parameter2_1,Parameter2_2,...|Command_3 Parameter3_1,Parameter3_2,...|...	CR

• Device Message Format:

Start	Address (optional)	Body	Delimiter
~	Device_id@	Message	CR LF

• Device Long Response – Echoing command:

Start	Address (optional)	Body	Delimiter
~	Device_id@	Command SP [Param1,Param2 ...] result	CR LF
