The Gefen DVI RS232 Extender over CAT5 with Ethernet
The DVI RS232 Extender over CAT-5 with Ethernet extends any DVI source to
a monitor, touch screen display, or other digital signage application placed at a
distance up to 330 feet (100 meters) using one CAT-5 cable. This product also
extends Ethernet and RS-232 using the same CAT-5 cable extension, allowing
access to control 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 moni-
tor or digital signage display with a DVI cable (not supplied). Use one CAT-5
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. 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 EXTENDER OVER CAT5 WITH
ETHERNET
• CAT-5 or CAT-6 cables should not exceed 330 feet (100 meters).
• Shielded (STP) CAT-5 or CAT-6 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 Extender over CAT5 with Ethernet 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 AND OPERATING
THE DVI RS232 EXTENDER OVER CAT5 WITH ETHERNET
How to Connect the DVI RS232 Extender over CAT5 with Ethernet
1. Connect the DVI source to the Sender Unit using the provided DVI cable.
Connect the DVI monitor to the Receiver Unit using a 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-6 cable.
3. Connect the Ethernet output port on the Receiver Unit to the remote device/
router with a CAT-5e or CAT-6 cable.
4. Connect a CAT-5e or CAT-6 cable between the Link port on the Sender Unit
and the Link port on the Receiver Unit.
NOTE: If terminating network cables in the field, please adhere to the TIA/
EIA568B specification (please see page 12).
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 to an available electrical outlet.
6. Power on the DVI monitor and the DVI source.

DIP SWITCHES
DIP Switch Location
On the bottom of the DVI RS232 Extender over CAT5 with Ethernet Receiver unit
there are four (4) DIP switches.
The DIP switches allow advanced EDID management of the DVI RS232
Extender over CAT5 with Ethernet 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
DIP 1 - EDID Mode
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* - Hot-Plug Detect
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 (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.

11
DIP SWITCH CONFIGURATION
DIP 3* - Supports DVI Connections
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 - RS-232 Mode
ON - Enable Field Upgrade Mode
• Allows the firmware to be upgraded on the Receiver Unit. In this mode, the
RS-232 portion of the extender will not function.
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.

CAT-5, CAT-5e, and CAT-6 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.
