Congratulations on your purchase of the 4x1 3G-SDI 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 3G-SDI Switcher
The Gefen 4x1 3G-SDI 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 3G-SDI Switcher 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 3G-SDI Switcher. A single 3G-SDI output connects on the output side. Power
is applied to the 4x1 3G-SDI 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 3G-SDI
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 3G-SDI Switcher. The currently selected input will be indicated by an active
LED.
4 3G-SDI Inputs 1-4
These inputs ports can accept (up to four) 3G-SDI, HD-SDI or SDI capable
devices. The selected input source is sent to the single output and is
selectable using the included RMT-4IR remote control or via the RS-232 serial
communication port.
5 3G-SDI Output
This output will accept a single 3G-SDI, HD-SDI or SDI output device.
6 RS-232 Serial Communications Port
This port is used to control input source swithcing on the 4x1 3G-SDI Switcher.
Please see page 9 for complete details on the serial communication features
that are used on this product.
7 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 3G-SDI Switcher
1. Connect up to four 3G-SDI, HD-SDI or SDI source devices to the 4x1
3G-SDI Switcher’s inputs using user supplied cables.
2. Connect a single 3G-SDI, HD-SDI or SDI capable device to the 4x1 3G-SDI
Switcher’s outputs using a user supplied cable.
3. Connect the included 5V DC power supply between the 4x1 3G-SDI
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 3G-SDI Switcher
The source input is selectable by using either the included RMT-4IR remote
control or the integrated RS-232 serial communication port.
Please see page 7 for RMT-4IR remote control operation.
Please see page 9 for RS-232 serial communication control operations.

The included RMT-4IR remote control is used to switch between inputs on the 4x1
3G-SDI Switcher. Only one input can be selected at a time and this input is then
output to the connected SDI output device.

RMT-4IR REMOTE DESCRIPTION

Why would I need to change the remote channel?
In some instances, the 4x1 3G-SDI Switcher may use IR codes that conflict with
other IR remote control devices. The unit may switch inputs when another brand IR
remote control is used or the RMT-4IR may cause other brand IR controlled devices
to behave unexpectedly.
I am experiencing the issues listed above. What do I do?
In these cases it is recommended to change the IR channel that the RMT-4IR
remote control and the 4x1 3G-SDI Switcher use. The IR channel is configured
independently on the RMT-4IR remote control and the 4x1 3G-SDI Switcher but the
channel selection must match on both units for proper operation.
How Do I change the Remote Channel?
There are service DIP switches on both the RMT-4IR remote control and the 4x1
3G-SDI Switcher for channel configuration. Please use the diagram below to locate
and change the IR channel to one that is not the default. Remember that the IR
channel must match on both the unit and remote control for successful operation.

The IR channel DIP switches for the 4x1 3G-SDI Switcher are located on an 4 bank DIP switch on the
underside of the unit. Locate DIP switches 1 and 2 (DIP switches 3 and 4 are not used) and make the
desired channel adjustments.

What features are available via the RS-232 serial communications port?
The 4x1 3G-SDI Switcher can accept commands through the RS-232 serial
communications port located on the rear panel. The current RS-232 control
features are:
• Switching/routing of inputs to the outputs without the RMT-4IR remote
control.
How do I use these features?
These features were initially intended for utilization by custom installers in
automated setups. However, these features can be tested by using any Windows
PC with the Hyperterminal program.
What pins are used for communication with the 4x1 3G-SDI Switcher?
Only pins 2 (Receive), 3 (Transmit), and 5 (Ground) are used for communication.
A null-modem adapter should not be used with this product.
