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).

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

IR REMOTE CONTROL UNIT INSTALLATION

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

IR REMOTE CONTROL UNIT CONFIGURATION
Resolving IR Code Conflicts
In the event that IR commands from other remote controls conflict 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.
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.

WALL MOUNTING INSTRUCTIONS
The GefenToolBox 4x1 Switcher for HDMI should be mounted vertically in
a wall or cabinet with wood/drywall screws as shown in the diagram above.
There should be an inch or two of clearance between the edges of the unit and
any walls or vertical surfaces to allow for enough clearance for insertion and
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
should undue stress be applied when connecting and disconnecting HDMI
cables.
