INTRODUCTION
Congratulations on your purchase of the Extender for DVI and RS232 Over One
Fiber Optic Cable. 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 Extender for DVI and RS232 Over One Fiber Optic Cable
The Extender for DVI and RS232 over One Fiber Optic cable is a complete
solution allowing DVI and RS-232 to be extended to a monitor, touch-screen
display, or other DVI device up to 1640 feet (500 meters) from the source.
A single strand SC fiber optic cable is used for the long distance extension,
providing excellent protection from background electromagnetic interference
(EMI), preserving both DVI and RS-232 signal integrity. Locking DVI, RS-232,
and power connectors ensure secure connections.
How It Works
The Sender unit is placed near the DVI source and the Receiver unit near the
Display. Connect the supplied DVI cable between the Sender unit and the DVI
source. Connect a second DVI cable between the Receiver unit and the display.
Connect the RS-232 cable from the RS-232 source to the Sender unit. Connect
the RS-232 cable between the Receiver unit and the RS-232 connection on the
display side. Connect a single strand of multi-mode SC-terminated fiber optic
cable between the Sender and Receiver unit. Connect the power supplies to both
the Sender and Reciever unit.

OPERATION NOTES
READ THESE NOTES BEFORE INSTALLING OR
OPERATING THE EXTENDER FOR DVI AND RS232 OVER ONE FIBER
OPTIC CABLE
•
•
When HDCP content is passed-through, DVI can only be extended up to
1000 feet (300 meters).
RS-232 data is bi-directional for direct commands and echo function or
status information. See page 13 for information on RS-232 settings.
IMPORTANT: Before connecting the power supplies to the Sender unit
and the Receiver unit, see page 12 for information on calibrating the
Extender.
•
When changing fiber optic cables, the calibration procedure must be
repeated.

CONNECTING THE EXTENDER FOR DVI AND RS232
OVER ONE FIBER OPTIC CABLE
How to Connect the
Extender for DVI and RS232 Over One Fiber Optic Cable
1. Connect the computer (or other DVI source) to the Sender unit using the
included Locking Dual Link DVI cable.
2. Connect the DVI display to the Receiver unit using a Dual Link DVI cable.
3. Connect an SC-terminated fiber optic cable to the Sender unit. Connect the
opposite end of the fiber cable to the Receiver unit.
4. OPTIONAL: Connect an RS-232 cable from the RS-232 serial port on the
controlling device to the RS-232 port on the Sender unit. Connect another
RS-232 serial cable from the RS-232 port on the Receiver unit to the RS-232
port of the RS-232 device.
IMPORTANT: Before connecting the power supplies to the Sender unit
and the Receiver unit, see page 12 for information on calibrating the
Sender unit and Receiver unit.

DIP SWITCH CONFIGURATION
DIP Switches
On the bottom of the Sender unit and Receiver unit are a bank of four (4) DIP
switches. These DIP switches provide control over EDID, Deep Color, and unit
Calibration.
It may be necessary to remove the strip of tape to expose the DIP switches.
To change the DIP switch settings, move the appropriate DIP switch to its ON or
OFF position using a small pointed object. The DIP switches and their functions
are shown below.
Sender unit
DIP 1 - EDID Mode
•
OFF - Local EDID
When Local EDID mode is used, the EDID will be assembled by copying
all video and audio features of the connected device. Deep Color support
will be manually controlled: If Deep Color is supported by the display(s),
DIP 2 should be set to the ON position (see DIP 2 - Deep Color, below). By
default, the unit is shipped with DIP 1 in the OFF position.
•
ON - Pass-Through EDID
Allows all video and audio features of the connected devices to be passed to
the source device without control over Deep Color.

DIP SWITCH CONFIGURATION
DIP 2 - Deep Color
NOTE: DIP switch 2 is only functional when DIP switch 1 is set to the
OFF position.
•
•
OFF - Enables Deep Color support (12-bit color)
Enables Deep Color support. In Pass-through EDID Mode, setting DIP 2 to
the OFF position has no effect since all EDID information is passed through.
ON - Forces 8-bit Color
Disables Deep Color in the EDID. Deep Color management is only available
when Local EDID is being used.
DIP 3 - Calibration Mode
•
OFF - Enables Calibration Mode
Enables Calibration Mode. Make sure to set DIP switch 3 on both the
Sender unit and Receiver unit when calibrating the Extenders. See page 12
for details.
•
ON - Calibration Mode Lock
Locks the calibration settings. Set DIP switch 3 on both the Sender unit and
Receiver unit to the ON position after the calibration process has completed.
See page 12 for details on the calibration process.

CALIBRATION PROCEDURE
Calibrating the Sender unit and Receiver unit
IMPORTANT: Before beginning the calibration process, make sure that
the Sender unit and Receiver are not powered
1. Make sure DIP switch 3 on both the Sender unit and the Receiver unit are in
the OFF position (see pages 9 and 11).
2. Connect one end of the fiber cable to the Sender unit. Connect the other
end of the fiber cable to the Receiver unit.
3. Connect the 5V DC Locking Power Supplies to the Sender unit and the
Receiver unit. Do not overtighten the locking connectors. Plug the power
cord into an available electrical outlet.
The LED indicators on both the Sender unit and Receiver unit will alternate from
red to green during the calibration process. The calibration process can take up
to 120 seconds to complete.
After the calibration process has finished, the LED indicators on both the Sender
unit and the Receiver unit will turn solid green. Set DIP switch 3 to the ON
position on both the Sender unit and the Receiver unit to lock the calibration set-
tings.
NOTE: If the fiber optic cable is changed, follow steps 1 - 3 to repeat the
calibration procedure.
Troubleshooting
•
•
•
If the Sender unit and Receiver unit did not complete the calibration process,
the indicator LEDs on both Sender unit and Receiver unit will be red. Check
the fiber connections carefully and cycle the power on both the Sender unit
and the Receiver unit and repeat the calibration procedure.
When the indicator LED at one unit is GREEN and the other is RED,
cycle power on the unit with the RED indicator. It is also recommended to
cycle power on both the Sender unit and the Receiver unit to perform a full
calibration.
If the calibration procedure continues to fail, contact Gefen Technical
Support under the Asking For Assistance section at the beginning of this
manual.
