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.
