GefenPRO
In the realm of video distribution, certain features are invaluable in a commercial or
broadcast environment. Accommodations such as a build-in power supply and at black
rack-mount enclosures set GefenPRO apart from our traditional products. Complex
distribution units allow for professional DVI, 3G-SDI, and HDMI signals to be routed and
converted easily and seamlessly, while being backed up by a renowned and dependable
technical support team. Gefen invites you to explore the GefenPRO product line and hopes
that you nd the solution that ts your needs.
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, Telnet, 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.
INTRODUCTION
NOTE: The GefenPRO 16x16 DVI Matrix only supports DVI-D.
The DVI connectors on the GefenPRO 16x16 DVI Matrix have
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 / enabled
by using the #lock_edid command through RS-232, Telnet, UDP, or using the Web
interface. See page 19 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 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.
• 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 60 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
OPERATION NOTES
IMPORTANT: If the unit is installed in a closed or multi-rack

IR REMOTE CONTROL
Installing the Battery
The Remote Control unit ships with two batteries. One battery is required for operation and
the other battery is a spare.
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.
Setting the IR Channel
The IR channel on the IR Remote Control must match the IR channel used by the DVI
16x16 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 16x16 DVI Matrix must also be set to IR
channel 0. See page 37 for information on how to change the IR channel on the DVI 16x16
Matrix.

RS-232 / IP CONTROL
IP Conguration
The 16x16 DVI Matrix supports IP-based control using Telnet, UDP, or the built-in
Web-based GUI. To set up IP control, the network settings for the 32x32 Modular Matrix
must be congured via RS-232. The default network settings for the matrix are as follows:
IP Address: 192.168.1.72
Subnet: 255.255.255.0
Gateway: 192.168.1.254
HTTP Port: 80
Telnet Port: 23
1. Connect an RS-232 cable from the PC to the 16x16 DVI Matrix. Also make sure that
an Ethernet cable is connected between the matrix and the network.
2. Launch a terminal emulation program (e.g. HyperTerminal) and use the RS-232
settings listed on page 37.
3. Set the IP address for the matrix using the #sipadd command (see page 27
for details).
4. Set the subnet mask using the #snetmask command (see page 27 for details).
5. Set the gateway (router) IP address using the #sgateway command
(see page 26 for details).
6. Set the Telnet listening port using the #set_tcp_term_port command
(see page 24 for details).
7. Set the HTTP listening port using the #set_http_port command
(see page 23 for details).
8. Power-cycle the matrix to reboot and complete all IP setting changes.
9. Type the IP address that was specied in step 3, in a web browser to access
the Web GUI or use the same IP address to Telnet to the matrix.
UDP Conguration
1. Set the UDP remote IP address for the matrix using the #set_udp_rip command
(see page 25 for details).
2. Set the UDP listening port for the matrix using the #set_udp_port command (see
page 24 for details).
3. Set the UDP remote port for the matrix using the #set_udp_rport command (see
page 25 for details).
NOTE: Depending upon the network, all related IP, Telnet, and
UDP settings will need to be assigned. Consult your network
administrator to obtain the proper settings.
