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.

The included RMT-4IR remote control is used to switch between inputs on the 4x1
3GSDI Switcher. Only one input can be selected at a time and this input is then
output to the connected SDI output device.
Example: Switch to the 3G-SDI source connected to In 3.
Point the Remote at the 4x1 3GSDI Switcher and press button 3 on the IR
Remote Control Unit.

IR REMOTE DESCRIPTION

IR REMOTE CONFIGURATION

Setting the IR Remote Channel on the RMT-4IR
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 IR
channel.
The DIP Switch bank on the IR Remote Control Unit is located underneath the
battery cover.

Left: Picture of the opened rear battery
compartment of the RMT-4IR remote showing
the exposed DIP Switch bank between the
battery chambers.
The IR channel selected on the IR Remote Control Unit must match the IR
channel assigned to the 4x1 3GSDI Switcher. For example, if you set both DIP
switches on the remote to the down position (IR channel 1), you must set the 4x1
3GSDI Switcher to use IR channel 1.
See page 9 on how to change the IR channel on the 4x1 3GSDI Switcher.

DIP SWITCHES
4x1 3GSDI Switcher Configuration
On the bottom of the unit, there is a bank of four (4) DIP switches. Each DIP
switch performs a different function.
DIP 1 - Termination Mode
ON - 100ΩTermination
• Adds a 100Ωtermination on the RS-485 line. This DIP switch should only be
used when RS-485 is enabled and if the line is to be terminated, usually on
the last device in the chain.
OFF (default) - No Termination
• For normal use and when using the RS-232 protocol.
DIP 2 - RS-232 / RS-485 Protocol
ON - RS-485
• Sets the product to use the RS-485 serial protocol. DIP switch 1 should be
set to the ON position. Refer to DIP switch 1 information, above.
OFF - RS-232
• Sets the product to use the RS-232 serial protocol.
DIP 3 / DIP 4 - IR Channel
• The IR channel assigned to the IR Remote Control must match the IR
channel assigned to the 4x1 3GSDI Switcher. The factory setting (default)
for DIP 3 and DIP 4 are in the OFF position. See page 8 for setting the IR
channel on the IR Remote Control Unit.
