CONNECTING AND OPERATING

THE GEFENTOOLBOX 4X1 SWITCHER FOR HDMI

How to Connect the GefenToolBox 4x1 Switcher for HDMI

1. Use HDMI cables (provided) to connect the source device(s) to the HDMI
input port(s) of the GefenToolBox 4x1 Switcher for HDMI.

2. Use additional user-supplied HDMI cables to connect an HDMI-compliant
display to the output port on the GefenToolBox 4x1 Switcher for HDMI.

3. Connect the included 5V DC power supply to the power receptacle on the

How to Operate the GefenToolBox 4x1 Switcher for HDMI

The top panel of the GefenToolBox 4x1 Switcher for HDMI contains a set of LED
indicators, displaying which input (source) is being routed to the output (display).
This allows for easy management and viewing of the input and output routing
state.

There is a single row of LED indicators on the front panel. To the left of the LED
indicator is a push button labeled “Input”. The numbers along the top of each
LED represents the currently selected Input (source): 1, 2, 3, or 4.

Example 1: Route Input (source) 2 to the Output

1. Ensure that an HDMI cable is connected from the source to HDMI In 2
and an HDMI cable is connected from the display to the Output port on the
Switcher.

2. Press the Input Select button until the LED under column 2 glows blue. If
the LED does not immediately appear under column 2, continue depressing
the Input Select button until the LED under column 2 is enabled (Fig 1.1).

Fig 1.1

3. Once the LED under column 2 is enabled, a picture will be displayed on the
display connected to the HDMI Output on the Switcher.

Automatic Switching

The GefenToolBox 4x1 Switcher for HDMI features Automatic Switching. When
a connected source is powered ON, the GefenToolBox 4x1 Switcher for HDMI
will automatically switch to that input. If the same device is powered-down, the
GefenToolBox 4x1 Switcher for HDMI will revert to the (original) active source.
The Switcher will always change to the last source device that was powered ON.

Automatic Switching can be enabled or disabled through RS-232. See page 14
for the command syntax.

NOTE: The IR Remote Control unit, RS-232, and the front-panel buttons will
always allow manual switching of source devices, even if Automatic Switching is
enabled.

IR REMOTE CONTROL UNIT DESCRIPTION

1 LED Button Press Indicator

This LED will activate momentarily upon each button press. This visual
indicator is to inform the user that a command has been sent by the IR
remote control.

2 Display and Source Selection Buttons

These buttons will be used to send display and source selections to the
GefenToolBox 4x1 Switcher for HDMI.

Routing Sources to Displays

Issuing a routing command is a simple process. There are a total of 4 buttons on
the RMT-4IR. The individual buttons represent the Inputs that are available for
the Output.

For example, to route the source connected to HDMI In 2 to the display, press
button 2 on the RMT-4IR.

IR REMOTE CONTROL UNIT INSTALLATION

Installing the IR Remote Control Battery

1. Remove the battery cover on the back of the IR Remote Control unit.

2. Insert the included battery into the open battery slot. The positive (+) side of

the battery should be facing up.

3. Replace the battery cover.
The Remote Control unit ships with two batteries. One battery is required for

operation and the other battery is a spare.

IR REMOTE CONTROL UNIT CONFIGURATION

Resolving IR Code Confl icts

In the event that IR commands from other remote controls confl ict with the
supplied IR remote control unit, changing the remote channel will alleviate this
issue. The IR remote control unit has a bank of DIP switches for setting the
remote IR channel.

The DIP Switch bank on the IR remote control unit is located underneath the
battery cover.

DIP Switches

It is important that the IR channel selected on the remote, match the IR channel
on the GefenToolBox 4x1 Switcher for HDMI for proper operation. For example,
if you set both DIP switches on the remote to the down position (toward the “1”
and “2”), IR channel 0, you must set the GefenToolBox 4x1 Switcher for HDMI to
use IR channel 0.

retraction of cables at the HDMI connectors.

For installation on a drywall surface, use a #6 drywall screw. It is recommended
when installing on a drywall surface that studs be used to secure the Switcher
