INTRODUCTION

Congratulations on your purchase of the 2x4 Switcher for HDMI 1.3. Your complete satisfaction is very important to us.

Gefen

Gefen delivers innovative, progressive computer and electronics add-onsolutions that harness integration, extension, distribution and conversion technologies. Gefen’s reliable,plug-and-playproducts supplementcross-platformcomputer systems, professional audio/video environments and HDTV systems of all sizes withhard-workingsolutions that are easy to implement and simple to operate.

The Gefen 2x4 Switcher for HDMI 1.3

Gefen’s 2x4 Switcher for HDMI 1.3 is equipped with two HDMI inputs and four HDMI outputs. Two inputs accommodate the simultaneous connection of up to two high definition video sources, such as satellite systems and HD DVD players. 3D content can be displayed when connecting a 3DTV and 3D source. Four outputs send the high definition audio/video signals to up to four high definition displays. Switching is done via the IR remote that is provided with the unit.

How It Works

You simply connect all your sources to the Switcher’s inputs. Then connect up to four displays on the output ports. Once the sources, the Switcher and the display(s) are powered and connected, you simply select which source you want to view using the IR remote.

OPERATION NOTES

READ THESE NOTES BEFORE INSTALLING OR

OPERATING THE 2X4 SWITCHER FOR HDMI 1.3

By default, display information from the display connected to HDMI output port 1 is sent back to the source. Therefore, the other display connected to the 2x4 Switcher for HDMI 1.3 must be capable of accepting the timings, resolutions and audio formats of the display that is connected to HDMI output port 1. It is recommended that the display with the lowest native resolution be connected to HDMI output port 1. This is to ensure that a compatible video signal will

be able to be displayed on all connected monitors. There is a generic EDID programmed into the 2x4 Switcher for HDMI 1.3 that can be used instead. See page 11 for more details.

IR REMOTE CONFIGURATION

Setting the IR Remote Channel on the RMT-8IR

In the event that IR commands from other remote controls conflict with the supplied IR Remote Control Unit, changing the remote IR channel will fix this issue. The IR Remote Control Unit has a bank of DIP switches for setting the Remote IR channel.

The DIP Switch bank is located underneath the battery cover.

The IR channel selected on the IR Remote Control unit must match the IR channel assigned to the 2x4 Switcher for HDMI 1.3. For example, if you set both DIP switches on the remote to the down position (IR channel 1), you must set the 2x4 Switcher for HDMI 1.3 to use IR channel 1.

Refer to page 10 on how to change the IR channel on the 2x4 Switcher for HDMI 1.3.

IR CHANNEL CONFIGURATION

Setting The IR Channel

Use the following procedure to set the proper IR channel on the 2x4 Switcher for HDMI 1.3.

1Press and hold the EDID button.

2While holding the EDID button, press and release theReset button. The input LED indicators, on the front panel, will represent the current IR channel for the Switcher: A blinking LED corresponds to DIP switch set to the ON position. An inactive LED corresponds to a DIP switch set to the OFF position.

In the illustration above, the LED for Input 1 is blinking and the LED for Input 2 is inactive. This indicates that the Switcher is set to IR channel 1.

IMPORTANT: The selected IR channel must be the same as the IR channel set on the IR Remote Control Unit (see page 9). Refer to the table below for setting the IR channel.

EDID MANAGEMENT

EDID Mode Selection

1.EXTERNAL MODE:

See page 12 for details on using the External EDID.

2.INTERNAL MODE:

To use this mode, press the EDID button on the rear panel until the frontpanel LED marked “Int” turns bright green. This mode will use a preset EDID, from the factory, that is stored in the Gefen 2x4 Switcher for HDMI 1.3. This pre-programmedstandard EDID data structure is compatible with most A/V display devices. All resolutions and audio formats specified in this EDID will be passed to the source device. See the tables below for a complete listing of the resolutions and audio formats listed in this EDID.

NOTE: All other HDMI devices/displays connected to the output portsMUST be compatible with at least one resolution/audio format specified in this EDID. It is recommended to set, on the source device, a common resolution and audio format shared by all attached devices/displays. This is to ensure a compatible signal is output to all connected devices/displays.

EDID MANAGEMENT

External EDID Management

The 2x4 Switcher for HDMI 1.3 features EDID Management. Before the source can send video or audio signals, the source device reads the EDID (Extended Display Identification Data) from the output devices connected to the Splitter. The EDID contains information about what type of A/V data that the source can send to each output device.

The 2x4 Switcher for HDMI 1.3 distributes a single source to multiple output devices. This involves reading EDID data from more than one device. Management of the EDID data is important to maintain compatibility between all devices.

The following EDID features are copied from Output 1:

Supported Resolutions

3D Support

Audio Features

EDID color features are built based on all attached displays, using the following rules:

Deep Color will be enabled if one or more displays are connected to the Splitter supporting Deep Color.

xvYCC (x.v.Color) is supported if all connected displays support it.

Display Connections:

If a display is not connected to Output 1, then no EDID changes are made, meaning that the previous EDID information will be used. This state will be in effect until a display is connected to Output 1 and the Splitter is powercycled.

EDID is built from Output 1 to the Input. The audio block will be copied from Output 1. EDID-copyingis performed only when the Splitter is reset orpower-cycled.
