The GefenPRO 16x16 DVI Matrix
Simplify the process of routing up to 16 DVI sources to any of 16 DVI monitors
without losing quality or resolution. The GefenPRO 16x16 DVI Matrix provides
a simple, reliable, and highly effective method of streamlining any installation
using multiple sources and outputs, taking the hassle out of managing multiple
connections. Each DVI source is accessible at all times by any monitor using the
front-panel buttons, IR remote unit, built-in RS-232 or using IP control.
How It Works
The GefenPRO 16x16 DVI Matrix has 16 DVI inputs and 16 DVI outputs. Using
the supplied DVI cables, connect 16 sources to the DVI input ports on the
GefenPRO 16x16 DVI Matrix’s input side. Connect the GefenPRO 16x16 DVI
Matrix’s 16 DVI outputs to the monitors. Plug in the power cord and power on the
GefenPRO 16x16 DVI Matrix. The connected monitors will show video according
to the routing selection.
NOTE: The GefenPRO 16x16 DVI Matrix only supports DVI-D. The DVI
connectors on the GefenPRO 16x16 DVI Matrix have all 29 pins.

READ THESE NOTES BEFORE INSTALLING OR
OPERATING THE GEFENPRO 16X16 DVI MATRIX
• The GefenPRO 16x16 DVI Matrix does not support HDCP content.
• Make sure that a DVI monitor is powered and connected to one of the DVI
outputs on the GefenPRO 16x16 DVI Matrix 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 through IP control. See page 21 for more information.
• There is no internal scaling in the GefenPRO 16x16 DVI Matrix. 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 configuration features are accessible
through the RS-232 serial command set.
• Routing and EDID features can be managed using the built-in IP control
feature.
• IMPORTANT: If the unit is installed in a closed or multi-rack assembly, do
not block the ventilation holes of the enclosure.

These buttons are used to select which source is routed to a monitor.
Routing Sources using the Remote Control unit
Issuing a routing command is a two step process. The first step is to select the
monitor (1-16) to which the source will be routed. The second step is to select the
source (1-16).
Example:
Route the source device connected to In 6 to the monitor connected to Out 4.
1. Press button 4 (Out 4) on the IR remote control unit.
2. Press button 6 (In 6) on the IR remote control unit.
The source connected to In 6 will be routed to the monitor connected to Out 4.

IR REMOTE INSTALLATION
Installing the RMT-16416IR 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.
CAUTION: Risk of explosion if battery is replaced by an incorrect type.
Dispose of used batteries according to the instructions.

IR REMOTE CONFIGURATION
How to Resolve IR Code Conflicts
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 fix 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.

compartment of the IR remote showing the
exposed DIP Switch bank between the battery

It is important that the IR channel on the Remote Control unit, matches the
IR channel set on the GefenPRO 16x16 DVI Matrix. For example, if both
DIP switches on the IR Remote Control unit are set to IR channel 0 (both DIP
switches down), then the GefenPRO 16x16 DVI Matrix must also be set to IR
channel 0. See page 25 on how to change the IR channel on the GefenPRO
16x16 DVI Matrix.

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 GefenPRO 16x16 DVI Matrix?
The GefenPRO 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 GefenPRO 16x16 DVI Matrix to provide a single EDID for each
source to read.
What options do I have to manage the EDID in the GefenPRO 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 GefenPRO 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 GefenPRO 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 GefenPRO 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

15
What features are available via the RS-232 serial communications port?
The GefenPRO 16x16 DVI Matrix 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 IR 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 a terminal program.
What pins are used for communication with the GefenPRO 16x16 DVI
Matrix?
Only pins 2 (Receive), 3 (Transmit), and 5 (Ground) are used for communication.
A null-modem adapter should not be used with this product.

RS-232 SERIAL CONTROL COMMANDS
RS-232 Features
RS-232 remote functions are used to control of this product’s features. Features
include input to output routing, EDID storage, EDID management, etc.
Functions Syntax
The syntax for each function is always the same:
#Character as the start flag →Function name →Space ( _ ) as function name
end flag →Parameter 1 →Space ( _ ) →Parameter n →Carriage Return ( \r )
Sample:
#FunctionName_param1_param2_param3_param4...\r
Syntax is NOT case sensitive.
Commands
Simplified syntax was used for command implementation for faster operation with
the device: # character – isn’t needed, the command name is reduced to 1 letter.
The commands are not case-sensitive.
Command Description
RRouting command
SRoutes a single input to all outputs
MReturns the current routing status of matrix
