Why GefenToolBox?
The GefenToolBox line offers portable and easy-to-install solutions for common
A/V system integration setups using DVI and HDMI connectivity. GefenToolBox
products are wall-mountable and small in size. GefenToolBox products are easily
transported in the field and are ready for immediate and simple installations in
working environments. These products come finished in a glossy color to blend in
with either a white wall or black cabinet.
The GefenToolBox DVIKVM Extra Long Range Extender
The DVIKVM ELR extender extends any DVI, Ethernet, RS-232, and USB source
from a computer to a monitor, touch screen display, or other digital signage appli-
cation over a distance up to 330 feet (100 meters) using two Cat-5 cables.
USB 2.0 data rates up to 480 Mbps are supported in addition to backward-com-
patibility with USB 1.1. The Receiver Unit allows the connections of up to two (2)
USB devices, providing access to printers, scanners, cameras, external storage
media, digital signage, and automated control systems.
This product uses Gefen ELR technology, allowing DVI, Ethernet, and RS-232
signals to travel along the same Cat-5 cable, reducing cabling costs and provid-
ing easier installation. A second Cat-5 cable is used for USB extension.
How It Works
Place the DVIKVM ELR Sender Unit next to the DVI source. Use the included
DVI cable to connect the computer or other DVI source to the Sender Unit. Use
the supplied USB cable to connect the USB host (source) device to the USB port
on the Sender Unit. Connect the Receiver Unit to the monitor or digital signage
display with a DVI cable. Connect the USB devices to the Receiver Unit. Use two
Cat-5 cables, up to 330 feet (100 meters), to connect the Sender Unit to the
Receiver Unit. Connect the included locking power supplies to the Sender Unit
and Receiver Unit, and then connect both power cords to available electrical
outlets.

OPERATION NOTES
PLEASE READ THESE NOTES BEFORE INSTALLING OR
OPERATING THE DVIKVM EXTRA LONG RANGE EXTENDER
• CAT-5 or CAT-6 cables should not exceed 330 feet (100 meters).

(UTP) CAT-5 or CAT-6 is acceptable.
NOTE: The shielded cable has an advantage by providing immunity to
Electromagnetic Interference (EMI), cell phones and A/C motors.
• The GefenToolBox DVIKVM Extra Long Range Extender Over One CAT5
features the ability to generate compatible EDID and Hot Plug signals when
working with different brands of source devices and monitors.
• This product does not support HDCP content with DVI.

Sender Unit
The Gefen DVIKVM Extra Long Range Extender contains DIP switches on the
bottom of the Sender Unit. Each DIP switch performs a different function.
DIP Switch 1 - Power Management (Default = ON)
• OFF - Enable Green Mode
Sender and Receiver Units are ON only when the DVI source is active. If the
DVI source enters sleep mode then both the Sender and Receiver Units will
enter Standby (“Green”) Mode.
• ON - Disable Green Mode
Sender and Receiver Units are always ON. This is the default position.
DIP Switch 2 - RS-232 Mode (Default = OFF)
• OFF - Pass-through Mode
Pass-through mode for RS-232. This is default position.
• ON - Firmware Upgrade Mode
Firmware Upgrade mode (See page 12 for instructions). If DIP switch 2 is in
the ON position, RS-232 cannot be extended.
DIP SWITCH CONFIGURATION
Two DIP switches located on
the bottom of the Sender Unit.

10
DIP SWITCH CONFIGURATION
Receiver Unit
The Gefen DVIKVM Extra Long Range Extender contains four (4) DIP switches
on the bottom of the Receiver Unit. Each DIP switch performs a different
function.
DIP Switch 1 - EDID Mode (Default = OFF)
• ON - Pass-Through Mode
DDC and HPD are passed through. Both the connection status and the full
video capabilities of the monitor are used by the source device.
• OFF - Local EDID Mode
Local EDID is used instead of the EDID from the display device. EDID
features newer than HDMI 1.3 are removed when the display is read. This
provides a general EDID which is compatible with more displays.
Four DIP switches located on the
bottom of the Receiver Unit.

DIP SWITCH CONFIGURATION
11
DIP Switch 2 - Hot Plug Detect (Default = OFF)*
• ON - HPD Pass-Through
HPD follows upstream HPD towards the source. The HPD signal will reflect
the connection status between the display device and the source device. If
the source or monitor is temporarily disconnected then reconnected, there
will be a delay of 20 - 30 seconds before the content is restored to the
monitor.
• OFF - HPD Always High
The HPD signal remains high regardless of the downstream HPD state.
If the source or monitor does not properly handle HPD (no picture after
connecting / reconnecting source or display), set this DIP switch to the OFF
position.
DIP Switch 3 - Supports DVI Connections (Default = ON)*
• ON - Disable HDCP
If a DVI connection is used, set DIP 3 to the ON position. DVI is supported
by disabling HDCP pass-through.
• OFF - Enable HDCP
If an HDMI device is connected, set DIP 3 in the OFF position.
DIP Switch 4 - RS-232 Mode (Default = OFF)
• ON - Enable Field Upgrade Mode
Allows the firmware to be updated on the Receiver Unit. If DIP switch 4 is
in the ON position, RS-232 cannot be extended. See page 12 for details on
upgrading the firmware.
• OFF - Pass-through Mode
When extending RS-232 between the Sender Unit and the Receiver Unit,
DIP switch 4 must be set to the OFF position.
*DIP switch is only operational when using Local EDID (DIP 1 = OFF).

FIRMWARE UPDATE
Updating the Firmware
1. Connect an RS-232 cable from the computer to the Sender Unit.
2. Set DIP switch 2 to the ON position.
3. Connect the 5V DC locking power supply to the Sender Unit.
4. Go to the directory where the firmware files are stored.
5. Double-click the .BAT file. A screen similar to the following will appear:
Found sink on port 4
Autodetect platform: full sink

NETWORK CABLE WIRING DIAGRAM
CAT-5, CAT-5e, and CAT-6 cabling comes in stranded and solid core types.
Gefen recommends using solid core cabling.
It is recommended to use one continuous run from one end to the other. In some
cases, connecting through a patch might not work.

14
WALL MOUNTING INSTRUCTIONS
The GefenToolBox DVIKVM ELR Sender and Receiver may be mounted
vertically in a wall or cabinet with wood/drywall screws as shown in the diagram
above. There should be an inch or two of clearance between the edges of the
unit and any walls or vertical surfaces to allow for enough clearance for insertion
and retraction of cables at the DVI and RS-232 connectors.
For installation on a drywall surface, use a #6 drywall screw. It is recommended
when installing on a drywall surface that studs be used to secure the Splitter
should undue stress be applied when connecting and disconnecting HDMI
cables.
