Congratulations on your purchase of the 16x16 DVI Matrix. 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 16x16 DVI Matrix
Now you can easily combine sixteen cross-platform computers and sixteen digital
displays using the 16x16 DVI Crosspoint Matrix. The Matrix provides a simple,
reliable and highly effective method of routing multiple computer workstations.
Each computer is capable of displaying video on any one of the 16 monitors.
There are 4 methods of controlling the Matrix - by using the front panel buttons,
the IR remote, a built-in RS-232 interface, and IP control over a local area
network.
How It Works
The 16x16 Crosspoint Matrix has sixteen DVI inputs and sixteen DVI outputs.
Using the supplied DVI cables, connect your sixteen computers to the DVI input
ports on the Matrix’s input side. Connect the Matrix’s sixteen DVI outputs to
the displays. Plug in the power cord and power on the Matrix. The connected
displays will show video according to the selection.
Note: This device only supports DVI-D.
INTRODUCTION

READ THESE NOTES BEFORE INSTALLING OR
OPERATING THE 16X16 DVI MATRIX
• The 16x16 DVI Matrix is not HDCP compliant
• There is a LOCAL EDID storage bank for each of the 16 DVI inputs. By
default, the EDID from the display connected to DVI Output 1 will be copied
to all 16 banks for use by each source device upon powering of the unit.
Please ensure that a display is powered and connected to the first output
port before applying power to the 16x16 DVI Matrix. If a display is not
detected, an internal default EDID (640x480) will be used. This feature can
be disabled by using the Secure Local EDID function via the RS-232 serial
controls. Please see page 17 for more information.
• There is no internal scaling in the 16x16 DVI Matrix. All of the attached
monitors must be able to display the resolutions output by the source
devices. For maximum compatibility it is recommended that only one
compatible/common resolution be used by all of the source devices.
• Advanced EDID features and IP configuration features are accessible via the
RS-232 serial communications. Please see page 13 for more information.
• Routing and EDID features can be accessed via a web browser using the IP
control feature built into the 16x16 DVI Matrix

the display (1-16) which a source will be routed to in the next step. Once the display
has been entered, the source can then be selected. Select the source (1-16) which
will be routed to the display selected in the previous step. For example, to route the
source connected to input 6 to the display connected to output 4 the input steps
would be the following:
1 Press button 4 (display) on the RMT-16416IR remote control.
2 Press button 6 (source) on the RMT-16416IR remote control.
3 The source will immediately be routed to the display.

To use the RMT-16416IR remote, remove the battery cover on the back of the
remote to reveal the battery compartment. Insert the included battery into the open
battery slot. The positive (+) side should be facing up. Ensure that both DIP (Dual
Inline Package) switches are in the OFF position. Replace the battery cover. The
remote ships with 2 batteries. One battery is needed for operation and the other
battery is complimentary.

How to Resolve IR Code Conflicts
In the event that IR commands from other remote controls conflict with the
supplied RMT-16416IR remote control, changing the remote channel will alleviate
this issue. The RMT-16416IR remote control and the 16x16 DVI Matrix both have
banks of DIP (Dual Inline Package) Switches for configuring the remote channel
that both units use to communicate. These settings must exactly match each
other for proper operation.
The DIP Switch bank on the RMT-16416IR is located underneath the battery
cover. DIP Switch bank for the 16x16 DVI Matrix is located on the back panel of
the unit. One DIP switch bank (8-switch) is provided and adjustment of remote
control frequencies and other switch behavior are managed by this switch .
Switches 1 and 2 on the RMT-16416IR directly correspond to DIP Switches 1 and
2 on the 16x16 DVI Matrix. Only switches 1 and 2 (of 8 in that bank) are used for
IR Code settings.

RMT-16416IR CODE CONFIGURATION

EDID. What is it and what is it used for?
Under normal circumstances, a source device (digital and analog) will require
information about a connected device/display to assess what resolutions
and features are available. The source can then tailor its output to send
only resolutions and features that are compatible with the attached device/
display. This information is called EDID (Extended Display Information Data)
and a source device can only accept and read one EDID from a connected
device/display. Likewise, the source an only output one resolution for use by a
connected device/display.
Why is EDID so important with the 16x16 DVI Matrix?
The 16x16 DVI Matrix is a complex piece of technology that replicates and
switches between multiple inputs and outputs. Each connected source device will
require one EDID to read. EDID management is carefully handled by the 16x16
DVI Matrix to provide a single EDID for each source to read.
What options do I have to manage the EDID in the 16x16 DVI Matrix?
First, it is important to note that each source device can only output one video/
audio signal type. This includes resolutions and timings. When multiple devices/
displays are used, such as with the 16x16 DVI Matrix, it is important to use
devices/displays that have similar or compatible resolutions and features. This
will ensure that the single video/audio signal produced by the source device is
accepted by all of the connected output devices/displays.
The user has the option, through utilization of the RS-232 serial interface, to
choose how the unit will manage the EDID from multiple DVI devices/displays.
Therefore the user has some control over the resolutions and features that
the source devices will output. The 16x16 DVI Matrix has a LOCAL EDID
management mode that will control how the EDID information is handled.
How do I change EDID modes in the 16x16 DVI Matrix?
EDID modes and IP configuration is managed via the RS-232 serial
communications port. See page 13 for more information on the RS-232 serial
communication features.
EDID MANAGEMENT FEATURE

What features are available via the RS-232 serial communications port?
The 16x16 DVI Matrix 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 outputs without the RMT-16416IR remote
control.
• Managing the EDID bank and EDID that is loaded into the LOCAL EDID.
• Upload new EDID’s to the EDID bank or directly to the LOCAL EDID
location.
• Manage IP settings.
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 and used by using any
Windows PC with the Hyperterminal program.
What pins are used for communication with the 16x16 DVI Matrix 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.
