VS-211UHD - Overview

3 Overview

The VS-211UHD is an automatic switcher for 4K@60Hz (4:2:0) HDMI and analog audio signals. The unit automatically switches one of two 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-211UHD 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-211UHD features:

 Maximum data rate 8.91Gbps (2.97Gbps per graphic channel)  Resolution support for up to 4K@60Hz (4:2:0) UHD  Support of Kramer Step-In over HDMI technology  HDTV compatible  Active switching – selectable manual or fast auto switching according to last

connected or preset priority

 HDMI, HDCP and DVI compliant  HDMI 1.4 support for Deep Color, 3D, ARC, up to 7.1 uncompressed audio

channels

 HDMI 1 input support for CEC and ARC  HDMI ARC de-embedding from output to balanced stereo audio line out,

uncompressed

 DVI 1.0 supported  Automatic video input detection and selection  Auto-power off when no HDMI input is detected (selectable timeout)  HDCP handling

VS-211UHD - Overview

 EDID configuration options  Default EDID  Contact closure for remote manual switching override  Audio embedding/de-embedding  Analog audio input per port  Firmware upgrade over RS-232, mini-USB  Support for Protocol 3000, EDID Designer, K-Upload via RS-232  Varied control options – front panel buttons, contact closure, IR, RS-232

VS-211UHD - Connecting the VS-211UHD

Always switch off the power to each device before connecting it to your VS-211UHD. After connecting your VS-211UHD, 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.

4 Connecting the VS-211UHD

To connect the VS-211UHD, as illustrated in the example in Figure 2, do the following:

1. Connect HDMI source 1 (for example, a Kramer DIP-31) to the INPUT1 HDMI connector.

2. Connect an unbalanced stereo audio source 1 to the INPUT 1 AUDIO

3.5mm mini jack (not shown in this example).

3. Connect HDMI source 2 (for example, a laptop) to the INPUT 2 HDMI connector.

4. Connect an unbalanced stereo audio source 2 to the INPUT 2 AUDIO

3.5mm mini jack (audio from the PC).

5. Connect the HDMI OUT connector to an HDMI acceptor (for example, a smart TV).

6. Connect the AUDIO OUT terminal block to a balanced stereo audio acceptor (for example, active speakers).

7. If required for remote switching, connect the INPUT SELECT terminal block to contact closure switches.

8. Connect the RS-232 terminal block to a controller (for example, a PC).

9. Connect a power cord to the device and plug it into the mains electricity (not shown in Figure 2).

4.1 Connecting a Serial Controller to the VS-211UHD via RS-232

The VS-211UHD operates at two baud rates – 9600 (default) and 115,200 (see all communication parameters in Section 8).

To connect a serial controller to the VS-211UHD:

 From the RS-232 9-pin D-sub serial port on the serial controller connect:

 Pin 2 to the TX pin on the VS-211UHD RS-232 terminal block  Pin 3 to the RX pin on the VS-211UHD RS-232 terminal block  Pin 5 to the GND pin on the VS-211UHD RS-232 terminal block

Color EDID

Pass deep color parameter of sink

Limit to RGB 8bpp

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 when using EDID Designer. (If using EDID Designer, refresh after copying)

HDCP

Enable HDCP support When On, 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 Off, the device does not

support HDCP on its input, even if HDCP is detected on the output.

Auto Embedding Port 1

If embedded audio is present (HDMI), embedded audio is passed If no embedded audio is present (DVI), the analog audio input is used

Always embed analog audio input 6

5 Operating the VS-211UHD

This section describes how to operate the VS-211UHD.

5.1 Switching – Manual and Auto

Switching can be performed automatically or manually using the front panel buttons, remote control, or control commands. This section describes using the 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 9.3.3.

5.1.1 Manual Switch Mode

In Manual switch mode, the VS-211UHD does not automatically switch to another channel even if an input signal is not detected on the manual input.

To select the Manual switch mode:

1. Press the AUTO button to turn the Auto LED off.

2. Press the IN1 or IN2 button to route this input to the HDMI output. The keys respond as follows:

 Input LED bright: input 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-211UHD automatically switches one of two 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.
