READ THESE NOTES BEFORE INSTALLING OR
OPERATING THE GEFENPRO 16X16 DVI MATRIX W/ FRONT PANEL PUSH BUTTON
CONTROL
• The 16x16 DVI Matrix w/ Push Button Control does not support HDCP content.
• Make sure that a DVI monitor is powered and connected to one of the DVI outputs on
the 16x16 DVI Matrix w/ Push Button Control before applying power. By default, the
Local EDID is read from the connected monitor and is copied to all 16 DVI inputs once
the Matrix has been turned on. If a monitor is not detected by the Matrix at power-on,
a default (internal) EDID of 640x480 will be used. This functionality can be disabled
using the Secure Local EDID function using RS-232 or IP control.
• There is no internal scaling in the 16x16 DVI Matrix w/ Push Button Control. Each
monitor attached to the Matrix must be able to display the resolutions output by the
source device(s).
For maximum compatibility it is recommended that only one common resolution
be used by each source device.
• Advanced EDID features and IP conguration features are accessible through the
RS-232 serial command set.
• Routing and EDID features can be managed using the built-in IP control feature.
• This matrix supports Dynamic EDID. See page 60 for details.
• The Gefen Firmware Upgrade Tool is a free downloadable application from Gefen that
provides automatic download and installation of rmware upgrades for this product.
See page 76 for more information.
• The Gefen Matrix Switcher Keyboard Controller is a free downloadable application
from Gefen that allows a computer keyboard to be used to switch between sources.
This application uses the Telnet protocol to control any Gefen switcher or matrix that
uses IP control.
Download the application here: http://www.gefen.com/support/download.jsp

How to Resolve IR Code Conicts
In the event that IR commands from other remote controls interfere with the supplied IR
Remote Control unit, changing the IR Remote Control’s IR channel will x the problem.
The IR Remote Control unit has a bank of DIP switches used for setting the IR channel.
The DIP switch bank is located underneath the battery cover.
It is important that the IR channel on the Remote Control unit, matches the IR channel set
on the 16x16 DVI Matrix w/ Push Button Control. For example, if both DIP switches on the
IR Remote Control unit are set to IR channel 0 (both DIP switches down), then the 16x16
DVI Matrix w/ Push Button Control must also be set to IR channel 0. See page 53 on how
to change the IR channel on the 16x16 DVI Matrix w/ Push Button Control.

ROUTING

Routing Inputs to Outputs
The following example illustrates the routing process. An input may be routed to a single
or multiple outputs. Multiple inputs cannot be routed to a single output. For this example,
we will route Input 6 to the following outputs: Output 3, Output 6, Output 7, and Output 9.
1. Press the Set button on the front panel. Pressing the Set button tells the matrix that
we want to perform a routing, masking, or preset operation. The Set button will glow
bright blue, indicating that it has been pressed.
2. The front-panel display will indicate that routing mode is active.
3. First, we need to specify the outputs. Press buttons 3, 6, 7, and 9. The selected
buttons will glow bright blue.
4. Select the desired input (source) button (1 - 16). For this example, we want to route
the source connected to Input 6 to each of the outputs in step 3. Therefore, press
button 6 on the bottom row. The selected input will glow bright blue.
NOTE: Only one input can be routed at a time. If the wrong input
button is accidentally pressed, then continue by pressing the
correct input button. The previous input button will automatically be
deselected.

5. Press the Set button on the front panel, again, to complete the routing operation.
The front panel display will indicate that the routing process has been completed.
6. After a few moments, the selected buttons on the front panel will turn off and the
matrix will return to the standby screen.
Getting the Current Routing Status of an Input
To display the current routing status of an input, press the desired input button on the front
panel of the matrix. Once the input button is pressed, the routed outputs will be displayed.
From our previous routing example, we already know that Input 6 is routed to Output 3, 6,
7, and 9. Let’s use this to illustrate how to retrieve the current routing status of an input.

Cancel button.
Getting the Current Routing Status of an Output
To display the current routing status of an output, press the desired output button on the
front panel of the matrix. Once the output button is pressed, the associated input will be
displayed. We’ll continue with the previous example.
1. Press the button for Output 3 on the matrix.
2. The current routing status for Output 3 will be displayed by the front panel buttons:
3. After a few moments the buttons will automatically turn off.
To immediately dismiss the routing status and return to the standby screen, press the
Cancel button.
One-to-One Routing
When an input-output pair share the same number, it is called “one-to-one” routing.
By default, the 16x16 DVI Matrix w/ Push Button Control is shipped in “one-to-one” mode.
This means that Input 1 is routed to Output 1, Input 2 is routed to Output 2, and so on.

Saving the Current Routing State
The 16x16 DVI Matrix w/ Push Button Control allows routing (and masking) states to be
saved to internal non-volatile memory. Each routing state can be recalled at a later time
(see Recalling a Saved Routing State). Even if the matrix is powered OFF, the presets will
be retained in memory.
We’ll illustrate an example by saving the routing state of Input 6, which we created
on page 13.
1. Press the PreSet button, twice. The PreSet button will glow bright blue, indicating
that it has been pressed. The front-panel display will indicate that the matrix is in
“save preset” mode:
2. Select a preset memory location by pressing any of the rst eight input buttons (1 - 8).
The matrix supports up to eight preset locations. For this example, press the button 1.
3. Press the Set button to store the preset.
