INTRODUCTION

Congratulations on your purchase of the 16x16 3GSDI 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 3GSDI Matrix

Now you can easily combine sixteen cross-platform computers and sixteen digital
displays using the 16x16 3GSDI Matrix. The Matrix provides a simple, reliable
and highly effective method of routing multiple computer workstations. Each
3GSDI source is capable of displaying video on any one of 16 3GSDI displays.
The Matrix can be controlled by using either the buttons on the front panel, the
built-in RS-232 interface, or the included IR remote.

How It Works

The 16x16 3GSDI Matrix has sixteen (16) inputs and sixteen (16) outputs.
Connect up to sixteen (16) 3GSDI sources to the 3GSDI input ports. Connect up
to sixteen (16) 3GSDI outputs to the displays. Plug in the power cord and power
on the Matrix. The connected displays will show video according to the selection.

OPERATION NOTES

READ THESE NOTES BEFORE INSTALLING OR

OPERATING THE 16X16 3GSDI MATRIX

• There is no internal scaling in the 16x16 3GSDI 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.

• Routing features can be accessed using RS-232 or using IP control.

• IMPORTANT: If the unit is installed in a closed or multi-rack assembly, do

not block the ventilation holes of the enclosure.

1 Activity Indicator

This LED will be activated momentarily each time a button is pressed.

2 Display and Source Selection Buttons (1 - 16)

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 fi rst 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.

Battery Slot

CAUTION: Risk of explosion if battery is replaced by an incorrect type.

Dispose of used batteries according to the instructions.

14

IR REMOTE CONFIGURATION

How to Resolve IR Code Confl icts

In the event that IR commands from other remote controls interfere with the
supplied IR Remote Control unit, changing the IR channel on the IR Remote
Control unit will fi 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.

Remote Channel 0:
Default

1 2

Remote Channel 2:

Exposed DIP Switch
bank between the
battery chambers.

Remote Channel 1:

1 2

Remote Channel 3:

1 21 2

It is important that the IR channel on the Remote Control unit, matches the IR
channel set on the 16x16 3GSDI 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 3GSDI Matrix must also be set to IR channel 0. See page 22 on
how to change the IR channel on the 16x16 3GSDI Matrix.

RS-232 SERIAL INTERFACE

What features are available via the RS-232 serial communications port?

The 16x16 3GSDI 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 RMT-16416IR remote
control.

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-based PC with a terminal program.

What pins are used for communication with the 16x16 3GSDI 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.

IP CONTROL

The GefenPRO 16x16 3GSDI Matrix supports IP-based control using an
integrated Web interface. To access this feature, an IP address, subnet, gateway,

and port number need to be set on the 16x16 3GSDI Matrix (Default IP:

192.168.0.70 Subnet: 255.255.255.0 Gateway: 192.168.0.1 Port: 80). Consult

the network administrator to obtain the proper IP address and settings for this
product to properly communicate on the network.

The IP control setting can be confi gured via the RS-232 control interface. Once
this has been accomplished, access to the Web Interface is possible. Simply type
the IP address that was assigned to the product in a web browser to access the

View Matrix Status page.

View Matrix Status

The Main Page will display the current status and can also be used to create

routes.

To create a new route, follow the steps below:

1. Select which outputs will display the source by clicking on each check box.

2. Select the radio button of the input that will be routed to each output.

3. Click the SWITCH button to update the new routing confi guration.

This page will automatically refresh every minute. However, at anytime the
“Refresh” button can be pressed to refresh the status of the Matrix.

25

IP CONTROL

Masking

The Masking page is used to hide an output from displaying any video. From

this page, all outputs can be set to “Active” or “Mask”. When an output is set to
“Active”, it will function normally. When an output is set to “Mask”, it will not output
any video. To set the “Active” or “Mask” mode, follow the steps below.

1. Select either “Active” or “Mask” for any number of desired outputs.

2. Press the “Submit” button to initiate the change(s).

After this command is complete the user will be returned to the Main Page.

This page will automatically refresh every minute, however, at anytime the
“Refresh” button can be pressed to refresh the status of the matrix.

NOTE: All masked outputs will become active if the unit is power-cycled.

26

IP CONTROL

IP Confi guration

The IP Confi guration page is used to set the IP settings that will be used to

access the Web interface. The following items can be confi gured from this menu.

• IP Address (Default: 192.168.0.70)

• Subnet (Default: 255.255.255.0)

• Gateway (192.168.0.1)

• Port (Default: 80)

•

•

To change these settings follow the steps below.

1. Enter the desired network information into the fi elds provided.

2. Press the “Save” button to initiate the change(s).

Note: After this command is complete the user will be returned to the View
Matrix Status page. Settings made on this page will not take effect until the

unit is restarted. Disconnect the power from the unit and reconnect power for
changes to take effect.

At anytime, the “Reset” button can be pressed to return the IP settings to their
defaults.
