4 VS-411UHD - Overview
3 Overview
The VS-411UHD is an automatic switcher for HDMI (up to 4K@60Hz (4:2:0)) and
analog audio signals. The unit 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. It also supports
Kramer’s Step-in over HDMI technology.
The unit can embed analog audio to an HDMI signal and can extract the audio from
either an input HDMI signal or an output Audio Return Channel (ARC) HDMI signal.
The VS-411UHD can output an analog audio source on the HDMI output even
when an HDMI source is not connected and enters sleep mode when no input is
detected.
The VS-411UHD features:
• Maximum data rate 8.91Gbps (2.97Gbps per graphic channel)
• Resolution support for up to 4K@60Hz (4:2:0) UHD
• Supports Kramer Step-In over HDMI technology
• HDTV compatible

4 Connecting the VS-411UHD
Always switch off the power to each device before connecting it to
your VS-411UHD. After connecting your VS-411UHD, 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.
To connect the VS-411UHD as illustrated in the example in Figure 2
:
1. Connect an HDMI source (for example, a laptop) to the INPUT 1 HDMI
connector and connect an analog audio source (for example, an audio
player) to the INPUT 1 3.5 mini-jack connector.
You can also connect a DVD player with a DVI connector, using a DVI-HDMI adapter to
transfer video signals
2. Connect HDMI sources (examples: document camera, Blu-ray player, or PC)
to the INPUT 2, 3, 4 HDMI connectors and connect audio inputs as required
to the INPUT 2, 3, 4 3.5 mini-jack connectors.
3. Connect the OUT HDMI connector to the HDMI acceptor (for example, an
LCD display).
4. Connect the AUDIO OUT terminal block connector to a balanced stereo
audio acceptor (for example, active speakers).
5. Set the AUDIO SELECT DIP-switches (see Section 5.1.2
)
6. Set the MODE/PRESET DIP-switches (see Section 5.1.2)
7. If required, connect a PC and/or controller to the RS-232 terminal block
connector (see Section 4.1
).
8. If required, connect the contact closure terminal block connectors (see
Section 6.2
).
9. Connect the 5V DC power adapter to the power socket and connect the
adapter to the mains electricity (not shown in Figure 2
).

4.1 Connecting a Serial Controller to the VS-411UHD via
RS-232
The VS-411UHD operates at two baud rates – 9600 (default) and 115,200 (see all
communication parameters in Section 9.1
).
To connect a serial controller to the VS-411UHD:
• From the RS-232 9-pin D-sub serial port on the serial controller connect:
• Pin 2 to the TX pin on the VS-411UHD RS-232 terminal block
• Pin 3 to the RX pin on the VS-411UHD RS-232 terminal block
• Pin 5 to the GND pin on the VS-411UHD RS-232 terminal block

4.2 Setting the DIP-Switches
The DIP-switches dictate the behavior of the VS-411UHD. All DIP-switches are off
by default.

1
Audio EDID
Pass audio EDID of sink.
Limit to 2-CH LPCM (effective only
after DIP 3 is set to on (down)).
2 Color EDID Pass deep color parameter of
sink.
Limit to RGB 8bpp (effective only
after DIP 3 is set to on (down)).
3
Lock EDID
Pass EDID of sink.
Lock current display EDID and the
current settings of DIPs 1 and 2 (the
settings of DIPs 1 and 2 cannot be
changed when DIP 3 is locked).
This state also allows copying the
default EDID or an EDID file to the
inputs (if using EDID Designer,
refresh after copying).
4 HDCP Enable HDCP support.
When Off, if the output
supports HDCP, the input
declares HDCP support. It
then handles HDCP on the
output and input actively. If
the output does not support
HDCP then the input does not
support HDCP.
Disable HDCP support.
When On, the device does not
support HDCP on its input, even if
HDCP is detected on the output.
