Congratulations on your purchase of the 4x1 3GSDI Switcher. Your complete
satisfaction is very important to us.

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.

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.
