5 Operating the VS-411UHD

This section describes the VS-411UHD setup.

5.1 Switching – Manual and Auto

Switching can be performed automatically or manually using the device’s keypad,

remote control, or control commands. This section describes using the keypad

buttons to select Auto or Manual switch modes. The same procedure can also be

used for controlling switching via the remote control. For information about

switching via control commands, see Section 10.3

5.1.1 The Manual Switching Mode

In the manual mode, the VS-411UHD acts as a regular switcher, switching the input

video and audio signals to the output via the four front panel INPUT buttons.

To select the Manual switch mode:

1. Press the AUTO/MANUAL button to turn the AUTO LED off.

.

2. Press the INPUT1 to INPUT4 button to route this input to the HDMI output.

The keys respond as follows:

• Input LED bright: input active and selected

• Input LED dim: input active and not selected

• Input LED off: input is not active and not selected

5.1.2 Auto Switch Mode

In Auto switch mode, the VS-411UHD automatically switches one of four HDMI

inputs to a predefined or the last connected input whenever the currently active

video signal is interrupted or whenever a higher-priority video signal is detected.

10 VS-411UHD - Operating the VS-411UHD

To select Auto switch mode:

1. Press the AUTO/MAN. button to turn the AUTO LED on.

2. Press the LAST/PRIO. button to select an auto switch mode:

• Last connected (LAST LED on) – The device always switches to a

newly detected active video source. When the device is powered on,

the output switches to the highest priority input

• Priority (LAST LED off) – The device always switches to the highest

priority input source. The default priority is Input 1 then Input 2.

5.1.3 Manual Override Mode

Auto switch mode can be overridden by a manual command, such as pressing an

input button or sending a control command. In such a case, the system switches to

the manually selected source. If this manually selected source is not active, the

system waits a set amount of time (10 seconds, default) and then switches back to

auto mode. Manual override selection is not stored in non-volatile memory.

5.2 Setting the Switching Speed

The VS-411UHD supports setting normal and fast (default) switching speeds.

To set switching speed modes:

1. Disconnect device power.

2. Press and hold one of the following buttons together with the OFF button:

• INPUT 1 button – for setting fast switching speed mode.

• INPUT 2 button – for setting normal switching speed mode.

3. Power the device on.

The device switching speed is modified.

5.3 Muting the Output

• Press the OFF button to mute the audio and video outputs

5.4 Copying the EDID

The EDID is a data structure transmitted by the display that enables the

VS-411UHD to recognize the display connected to the output. The VS-411UHD

acquires and stores the EDID to make reconnection to the display effortless.

When the device is first powered on, it has default EDID loaded. The device

automatically reads and saves the first read EDID. Use DIP-switches 1-3 to set

EDID functionality (see Section 4.2

While copying EDID data, the input port’s HPD function changes from Low to High

which may affect the channel’s auto-switching.

The device automatically recognizes EDID differences between
input and output channels based on parts of the EDID data,
including manufacturer, serial number, and first block check-sum
information. EDID data is not copied if any difference is recognized.

Note: If a corrupted EDID is copied, the device loads the default
EDID on all inputs.

).

5.5 Setting the 5V Output Time Delay

Use DIP-switch 8 to set the delay time. Off (Up) delays 15 seconds, On (Down)

delays 15 minutes. A Protocol 3000 command can modify the delay time.

When there is no signal clock or 5V input on all inputs for the set delay, the device

shuts down the 5V output.

5.6 Setting HDCP Capability

The VS-411UHD supports HDCP communication automatically, by default. When

HDCP is detected in the input signal, it is enabled in the output signal. You can also

disable HDCP support using DIP-switch 4 (see Section 4.2

HDCP support is universal for all inputs.

audio channels.

5.7 Setting Audio Output

The VS-411UHD enables customizing the audio output by embedding audio in

HDMI, de-embedding HDMI ARC from output to the uncompressed balanced stereo

audio line out, or routing the HDMI / analog inputs to the uncompressed balanced

stereo audio line out.

5.7.1 Embedding Audio in HDMI

The VS-411UHD can output audio to the HDMI Out port from the original HDMI

input or the Analog unbalanced 3.5mm audio input, by embedding it in the HDMI

input signal. The VS-411UHD enables setting the audio output separately for each

input using DIP-switches 5 and 6 (see Section 4.2

An Input 1 analog audio signal can only be embedded in the Input 1
HDMI signal.

An Input 2 analog audio signal can only be embedded in the Input 2

5.7.2 Outputting Audio from ARC or Device Inputs

The VS-411UHD can output audio to the balanced stereo Audio Out terminal block

from the following input sources:

).

VS-411UHD - Operating the VS-411UHD

• ARC – In this mode, the device does not enable embedding audio in the

HDMI signal.

• HDMI inputs / Analog unbalanced 3.5mm audio inputs – In this mode, the

balanced stereo Audio Out terminal block and the HDMI Out port both output

audio. The Audio Out terminal block mutes the audio when the input audio

signal is not LPCM.

Use DIP-switch 7 to set output to ARC / device inputs (see Section 4.2

When de-embedding multichannel audio, the device outputs FL
(front left) and FR (front right) channels only and cuts the rest of the

).

13

5.8 Using the Remote Control

You can use the RC-IR3 wireless remote control to control the VS-411UHD via the

built-in IR receiver on the front panel. For more information, see

www.kramerav.com/Product/RC-IR3

5.9 Step-In Support

The VS-411UHD supports programmable step-in functionality when used in

conjunction with compatible step-in devices, such as the SID-X3N and DIP-31

(using an HDMI cable that supports HEC, the HDMI Ethernet Channel).

When ARC mode is enabled, Input 1 step-in mode is disabled. If you require step-in

mode on Input 1, set the audio output to the device inputs (see Section 5.7.2

5.10 Using VCOM on USB

USB can work as a port for virtual com (VCOM). Verify that the USB port on the PC

that connects to the VS-411UHD is configured as a VCOM port. You may need to

install a driver to do this. Use a tool such as Hercules or K-Config to use Protocol

3000 over USB. For more information on using the commands see Section 10

10 Protocol 3000

The VS-411UHD can be operated using the Kramer Protocol 3000 serial

commands. The command framing varies according to how you interface with the

VS-411UHD. 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:

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):

• As a driver in K-Config (Kramer configuration software):

24 VS-411UHD - Protocol 3000

You can enter commands directly using terminal communication software (e.g.,

Hercules) by connecting a PC to the serial port on the VS-411UHD. 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 VS-411UHD, 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

VS-411UHD - Protocol 3000

25

• ~ – 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.

10.2 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 SP Parameter_1,Parameter_2,…

VS-411UHD - Protocol 3000

• Command String – Formal syntax with command concatenation and

addressing:

Command_1 Parameter1_1,Parameter1_2,…|
Command_2 Parameter2_1,Parameter2_2,…|
Command_3

Parameter3_1,Parameter3_2,…|…

• Device Message Format:

• Device Long Response – Echoing command:

Command SP [Param1,Param2 …] result
