Congratulations on your purchase of the 4x1 3GSDI Switcher. Your complete

satisfaction is very important to us.

Gefen

Gefen delivers innovative, progressive computer and electronics add-on solutions

that harness integration, extension, distribution and conversion technologies.

Gefen’s reliable, plug-and-play products supplement cross-platform computer

systems, professional audio/video environments and HDTV systems of all sizes

with hard-working solutions that are easy to implement and simple to operate.

The Gefen 4x1 3GSDI Switcher

The Gefen 4x1 3GSDI Switcher allows any one of four high-bandwidth 3G-SDI,

HD-SDI or SDI sources to be switched to a single output without a switching

delay or loss of signal quality. Ideal for cutting equipment costs in the studio by

enabling shared signal routing, this product supports source resolutions up to

1080p and has convenient switching methods.

How It Works

Up to four 3G-SDI sources connect to BNC input jacks on one side of the Gefen

4x1 3GSDI Switcher. A single 3G-SDI output connects on the output side. Power

is applied to the 4x1 3GSDI Switcher and a vibrant video picture is transmitted

to the output device. Any 3G-SDI input source is selectable via the included

IR remote control or a selector button on the front panel of the 4x1 3GSDI

Switcher. Selection of sources may also be performed by using the RS-232

communications port.

1 IR (Infrared) Receiver

This receiver will accept command for switching between input devices using

the included RMT-4IR remote control. Line of sight must be preserved between

the remote and unit for proper operation.

2 Power LED Indicator

This LED will become active once the included 5V DC power supply is properly

connected between the unit and an open wall power socket.

3 Selected Input LED Indicator

There is a 4 LED array to indicate which source is currently selected on the 4x1

3GSDI Switcher. The currently selected input will be indicated by an active LED.

4 3G-SDI Input Source Selector Button

Pressing this button will manually switch between as many as four SDI sources

connected on the rear of the Switcher. The inputs ports (item 5 below) can

accept (up to four) 3G-SDI, HD-SDI or SDI capable devices. The selected

input source is sent to the single output. Selection of input sources may also

be accomplished using the included RMT-4IR remote control or via the RS-232

serial communication port.

5 3G-SDI Inputs 1-4

These inputs ports can accept BNC connections from (up to four) 3G-SDI, HD-

SDI or SDI capable devices.

6 3G-SDI Output

This output will accept a single 3G-SDI, HD-SDI or SDI output device with a

standard BNC connector.

7 RS-232 Serial Communications Port

This port is used to control input source swithcing on the 4x1 3GSDI Switcher.

Please see page 10 for complete details on the serial communication features

that are used on this product.

8 5V DC Power Receptacle

This receptacle will require power from the included 5V DC power supply for

proper operation. Connect the included power supply between this port and an

open wall power socket.

How to Connect the 4x1 3GSDI Switcher

1. Connect up to four 3G-SDI, HD-SDI or SDI source devices to the 4x1 3GSDI

Switcher’s inputs using user supplied cables.

2. Connect a single 3G-SDI, HD-SDI or SDI capable device to the 4x1 3GSDI

Switcher’s outputs using a user supplied cable.

3. Connect the included 5V DC power supply between the 4x1 3GSDI

Switcher’s power receptacle and an open wall power socket.

4. Initialize (power on) the output device ﬁrst and the source devices second.

How to Operate the 4x1 3GSDI Switcher

The source input is selectable by using either the included RMT-4IR remote

control or the integrated RS-232 serial communication port. The LED indicators

on the front panel indicate the currently selected input. If the selected input has

no source connected, the LED will be red. If the selected input is connected to a

source, the LED will be green.

Please see page 7 for IR Remote Control Unit operation.

Please see page 10 for RS-232 serial communication control operations.
