4K Ultra HD 4x2 Matrix for HDMI

Operating Notes

EDID contains the A/V capabilities of a display device in regards to video resolutions and audio formats supported. This information is used by the source device to determine the format of the A/V signal on the outputs. The GefenToolBox 4K Ultra
HD 4x2 Matrix for HDMI incorporates advanced EDID management to ensure
compatibility with all sources and display devices.
The GefenToolBox 4K Ultra HD 4x2 Matrix for HDMI can detect the presence of Deep
Color (12-bit signal) automatically and will disable Deep Color EDID features across
all other outputs if any connected device or display is not capable of processing Deep Color. This automatic behavior ensures compatibility among all output devices in a mixed-device environment. This feature cannot be disabled.
When powering the GefenToolBox 4K Ultra HD 4x2 Matrix for HDMI or if the EDID mode is changed, the matrix will undergo a momentary initialization sequence. This is normal operation and may take a few seconds.
The best way to operate and congure this unit is to use the built-in Web interface, which can be accessed by entering the IP address of the matrix into the address bar of
any Web browser. See the section RS-232 and IP Conguration for more information
about this feature.

Routing Basics

Determining the Current Routing State

On the bottom-left portion of the matrix, there are two rows of four LED indicators. The top row of LED indicators displays the routing state of Out 1. The bottom row displays the routing state of Out 2. A row of numbers (1 - 4) is printed above the two rows of LED indicators. Each LED indicator represents an input (In 1 - In 4) on the matrix. The LED
indicator for the currently selected input will glow bright green.
LED indicates that In 1 is routed to Out 1
LED indicates that In 3 is routed to Out 2

Routing Basics

Routing Inputs to Outputs

To the left of each row of LED indicators, there are two push-buttons labeled Out 1
and Out 2. To change the routing state of an output, press and release the button of the desired output to advance to the next input.
In the example below, the source connected to In 3 is currently routed to Out 2.
To route In 4 to Out 2, press and release the Out 2 button.
In 3 is routed to Out 2
Out 2 is now set to In 4Button for Out 2
To route the source connected to Out 1 to another input, consecutively press and release the Out 1 button until the desired input is selected.
When an output is routed to input 4, pressing and releasing the button will return the output to input 1.

Using the IR Remote Control

The included IR remote control unit can also be used to switch between each input. There are two columns of four buttons each on the IR remote.
1. Point the included IR remote control unit at the IR sensor on the top panel. If an IR extender is being used, then both IR sensors will be used to receive IR signals.
Buttons 1 - 4 control the routing for Out 1 (In 1 - In 4) and buttons 5 - 8 control the routing for Out 2 (In 1 - In 4).
2. Press the desired button on the IR remote control to select the output and input to be routed.

Switching Modes

FAST SWITCHING TECHNOLOGY

What is Fast Switching Technology?

Fast Switching Technology (FST) is a Gefen software implementation for HDMI products. FST was created to improve the lengthy HDMI authentication process, based on the HDMI and HDCP specications.
FST provides quicker audio/video source switching and greatly improves the overall audio/
video system behavior and performance when more than one HDTV display is used in the system setup.
FST allows connecting / disconnecting or turning ON / OFF of HDTV displays without
having these activities affect other Hi-Def sources routed to any other HDTV display in the same system.

Fast Mode vs Slow Mode

Use fast switching mode to improve performance when connecting / disconnecting Hi-Def sources, and powering ON / OFF HDTV displays.
Use slow mode when the source does not support multiple devices. When set to slow
switching mode, the 4K Ultra HD 4x2 Matrix for HDMI will follow the standard authentication process, based on the HDMI and HDCP specications.

Selecting the FST Mode

1. Press and release the FST button, using a paper clip or other pointed object,
to toggle between Fast and Slow modes.
2. The LED indicator will display the current FST mode.
Press the FST button to
switch the FST mode

Audio Modes

The 4K Ultra HD 4x2 Matrix for HDMI provides the capability to switch between 2-channel
and multichannel audio output.
Use this audio mode when all displays (and/or other sink devices) support only 2-channel LPCM audio.
1. Press and release the Audio button, using a paper clip or other pointed object, to toggle between 2-channel and multichannel audio modes.
2. The LED indicator will display the current audio mode.
Supported audio formats
NOTE: In order for the audio channel mode to be selected, the EDID switch must be set to the Int position. If the EDID switch is set to the Ext position, then the Audio switch will have no effect
on the audio output signal. See Setting the EDID Mode for more information on using the EDID.

Press the Audio button to switch the audio mode

NOTE: When the Audio Mode is set the 2CH, the internal EDID will restrict the audio output to 2-channel LPCM, regardless of the audio
input format.

Operating the 1:8 Splitter for HDMI 4K x 2K

EDID Modes

The 4K Ultra HD 4x2 Matrix for HDMI features EDID Management. Before the source can send video and/or audio to the display (sink), the source reads the EDID (Extended Display Identication Data) from the display (sink) devices connected to the splitter. The EDID
contains information about what type of audio/video data that the source can send to each
output device. The splitter can use either the downstream EDID (from the display/sink) or the built-in internal EDID.

Available Modes

Internal EDID
Use this EDID mode if problems are encountered when using the external EDID. The built-in internal EDID provides the source device with a “generic” EDID which can be used by all display (sink) devices. The use of the internal EDID also provides
control of the audio output format.
External EDID
When set to Ext mode, EDID data will be fetched from each display (or other sink
device) that is connected to the outputs of the matrix. Once this information is gathered, the matrix “builds” an EDID based on the highest video and audio formats
that are supported by both sink devices. This EDID is then transmitted to each source device.
Custom EDID
When set to Custom mode, the matrix will use a customized EDID conguration
selected by the user. For example, each input can be individually set to different EDID modes to suit the needs of each input.

Selecting the EDID Mode

1. Press and release the EDID button, using a paper clip or other pointed object,
to toggle between internal, external, and custom EDID modes.
2. The LED indicator will display the current EDID mode.
See Table 2.1, on the next page, for specications on the internal EDID.
