The Gefen 16x16 DVI Matrix

Now you can easily combine sixteen cross-platform computers and sixteen digital
displays using the 16x16 DVI Matrix. The 16x16 DVI 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, or through IP Control over a local area
network.

How It Works

The 16x16 DVI Matrix has sixteen DVI inputs and sixteen DVI outputs. 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. Connect the power supply to the
Matrix and connect the power cord to an available wall outlet. The connected
displays will show video according to the selection.

NOTE: This device only supports DVI-D.

OPERATION NOTES

READ THESE NOTES BEFORE INSTALLING OR

OPERATING THE 16X16 DVI MATRIX

• The 16x16 DVI Matrix will not pass HDCP content.

• 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 confi guration features are accessible via the
RS-232 serial communication port. Please see page 14 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.

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 16x16
DVI Matrix.

Routing Sources to Displays

Issuing a routing command is a two step process. The fi rst step will be to select a
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.

RMT-16416IR REMOTE INSTALLATION

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
In-line 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.

RMT-16416IR REMOTE CONFIGURATION

How to Resolve IR Code Confl icts

In the event that IR commands from other remote controls confl ict with the RMT-
16416IR remote control, changing the remote channel will alleviate this issue.
The RMT-16416IR remote contains a set of DIP (Dual In-line Package) switches
for setting the IR channel for the remote.

The DIP Switch bank on the RMT-16416IR is located underneath the battery
cover.

IMPORTANT: The IR channel on the Matrix must match the IR channel on the
remote. Please see page 26 for details.

EDID MANAGEMENT FEATURE

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 confi guration is managed via the RS-232 serial
communications port. See page 14 for more information on the RS-232 serial
communication features.
