The Gefen DVI RS232 ELR Extender
The DVI RS232 ELR Extender extends any DVI source to a monitor, touch
screen display, or other digital signage device placed at a distance up to 330 feet
(100 meters) using one CAT-5e cable. This product also extends Ethernet and
RS-232 using the same CAT-5e cable, allowing access and control of devices
using RS-232.
How It Works
Place the Sender unit next to the DVI input source. Use the included DVI cable to
connect the source to the Sender unit. Connect the Receiver unit to the monitor or
digital signage display with a DVI cable (not supplied). Use one CAT-5e cable, up
to 330 feet (100 meters), to connect the Sender unit to the Receiver unit. Connect
an RS-232 serial cable from the RS-232 port on the Sender unit to the RS-232
control device. Use another RS-232 cable to connect the RS-232 port on the
Receiver unit to the RS-232 device. Connect the Ethernet ports on both the
Sender unit and the Receiver unit to any computer source and extended Ethernet
device.

OPERATION NOTES
PLEASE READ THESE NOTES BEFORE INSTALLING OR
OPERATING THE DVI RS232 ELR EXTENDER
• CAT-5e or CAT-6a cables should not exceed 330 feet (100 meters).
• Shielded (STP) CAT-5e or CAT-6a is recommended. However, un-shielded
(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 DVI RS232 ELR Extender 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.

CONNECTING
THE DVI RS232 ELR EXTENDER
How to Connect the DVI RS232 ELR Extender
1. Connect the DVI source to the Sender unit using the provided DVI cable.
Connect the DVI monitor to the Receiver unit using another DVI cable.
2. Connect an Ethernet cable from the device/router to the Ethernet input port
on the Sender unit with a CAT-5e or CAT-6a cable.
3. Connect the Ethernet output port on the Receiver unit to the remote device/
router with a CAT-5e or CAT-6a cable.
4. Connect a CAT-5e or CAT-6a cable between the Link port on the Sender unit
and the Link port on the Receiver unit.
NOTE: If terminating network cables in the eld, please adhere to the TIA/
EIA568B specication (please see page 13).
5. Connect the 5V DC locking power supplies to the Sender unit and Receiver
unit. Do not overtighten the locking connectors. Plug the two (2) power
supplies into an available electrical outlet.

DIP SWITCHES
DIP Switch Location
On the bottom of the DVI RS232 ELR Extender Receiver unit there are four (4)
DIP switches. The Sender unit has two DIP switches.
The DIP switches allow advanced EDID management of the DVI RS232 ELR
Extender which may be necessary when using different brands of hardware. The
DIP switches allow control over the EDID, HPD (Hot Plug Detect), and RS-232
modes.

DIP SWITCH CONFIGURATION
Sender Unit
DIP 1 - ON
ON (default) - Disable
• Power is always on.
OFF - Enable
• Power is enabled only if the DVI source is connected and active. If the DVI
source enters standby mode then both the Sender Unit and Receiver Unit
will enter Green Mode. In Green Mode, both the Sender and Receiver Unit
will each consume less than 1 W of power.
DIP 2 - OFF
ON - Enable Field Upgrade Mode
• Allows the rmware to be upgraded on the Sender Unit. Both DIP switches
(1 and 2) on the Sender unit must be set to the ON position to perform a
rmware upgrade. If DIP switch 2 is in the ON position, RS-232 cannot be
extended.
OFF (default) - RS-232 Pass-through
• Use when extending RS-232 between the Sender Unit and the Receiver
Unit. DIP switch 4 must be set to the OFF position for normal operation of
the DVI RS232 Extender over CAT5 with Ethernet.

11
DIP SWITCH CONFIGURATION
Receiver Unit
DIP 1 - OFF
ON - External EDID Mode
• DDC and HPD are passed through. Both the connection status and the full
video capabilities of the monitor. The HPD status will also be detected by
the source device.
OFF (default) - Internal 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.
DIP 2* - OFF
ON - HPD Pass-Through
• HPD follows upstream HPD towards the source. The HPD signal will reect
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 (default) - 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 con-
necting / reconnecting source or display), set this DIP switch to the OFF
position.
*DIP switch is only functional when DIP switch 1 is set to OFF.

12
DIP SWITCH CONFIGURATION
Receiver Unit
DIP 3* - ON
ON (default)
• If a DVI connection is used, set DIP 3 to the ON position. DVI is supported
by disabling HDCP pass-through.
OFF
• If HDMI is connected, set DIP 3 in the OFF position.
*DIP switch is only functional when DIP switch 1 is set to OFF.
DIP 4 - ON
OFF - Enable Green Mode
• When DIP switch 1 is set to the OFF position, the Receiver unit is powered
only when 5V is present on the HDMI / DVI cable. Automatic Power Mode
consumes less than 1 Watt of power.
ON - Disable Green Mode
• If DIP switch 1 is set to the ON position, then the Receiver unit is placed in
Power Always Mode. In this mode, the Receiver unit is always powered.
IMPORTANT: The Green Mode feature on the Receiver unit is
not implemented on hardware versions prior to 9502. Check the
hardware version, printed on the bottom of the Receiver unit. For
example, the sample image below indicates hardware version
9401 which does not have the Green Mode feature.

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