Congratulations on your purchase of the HDMI RS-232 Extender. Your complete
satisfaction is very important to us.

HDMI RS-232 Extender
Extending state-of-the-art digital video displays, computer monitors and touch
screens has never been easier. Distances up to 150 feet at 1080p resolution
(300 feet at 1080i resolution) are guaranteed to perform beautifully, giving you a
reliable method of all-digital extension while streamlining your installation cabling
needs.
How It Works
You simply connect the HDMI RS232 Extender sender unit to your HDMI and
RS232 source using the supplied cables. Your RS232 device and the HDMI
display plugs into the HDMI RS-232 Extender’s receiver unit. Two CAT-5 cables
connect the sender and the receiver units to each other allowing for up to 300
feet of extension (300 feet at 1080i resolution or 150 feet of extension at 1080p
resolution). You can use the optional Gefen IR Emitter cable to extend IR signals.
READ THESE NOTES BEFORE INSTALLING OR
OPERATING THE HDMI RS-232 EXTENDER
Use two industry standard CAT-5, CAT-5e or CAT-6 cables to operate the• HDMI RS-232 Extender. Gefen recommends CAT-6 cabling for maximum
performance.
For 1080i video, maximum extension is 300 feet (91 meters).•
For 1080p video, maximum extension is 150 feet (45 meters).•
IR repeater functionality is only from the receiving unit to the sending unit. IR• data cannot be transmitted from the sending unit to the receiving unit.

HDMI RS-232 EXTENDER CONFIGURATION
HOW TO EQUALIZE THE VIDEO SIGNAL
The sender and receiver units both have sets of dip switches located on the
underside of their casings. There is a piece of silver metallic tape that must
be removed to expose these dip switches. Each unit carries a bank of 4 dip
switches. Dip switches 1 and 2 on both the sending and receiving units are used
in this procedure. Dip switches 3 and 4 are not used. By default, all dip switches
on the sending and receiving units should be in the OFF position (Auto EQ On).
To turn off auto equalization, turn dip switch 1 on the receiving unit to the ON
position (Auto EQ off). With this setting please follow the steps below to equalize
the picture.
Insert a small flat head tool into the trim pot on the receiver unit.1.
Turn the trim pot in a clockwise fashion until it comes to a stop. Do not force2. the trim pot beyond this point. Doing so may break the trim pot.
Slowly turn the trim pot counter-clockwise in millimeter increments until the3. image stabilizes and all video noise disappears.
Carefully remove the adjustment tool.4.
NOTE: If your cable run is beyond 130 feet, or the following steps do not produce
any video, it may be necessary to increase the boost from the sending unit. Use
the chart below to increase the boost by changing the sender dip switches. Once
a new boost setting is set, repeat steps 1 through 4 from above.
Sender Dip Switch Settings
Setting Switch 1 Switch 2
No Boost (Default) OFF OFF
Medium Boost OFF ON
High Boost ON OFF
Very Low Boost ON ON
Receiver Dip Switch Settings
Setting Switch 1 Switch 2
Manual EQ ON OFF
Auto EQ (Default) OFF OFF
The HDMI RS-232 Extender has built-in auto equalization that will automatically
tune out any unwanted video noise. This feature is reliable with premium cable
runs up to a maximum of 130 feet. It may be necessary to disable this feature if
there is either no video being displayed on initial start-up, there is video noise
in the image, or the cable run exceeds 130 feet. First, verify that all the proper
connections have been made and that all devices are powered on before
attempting to disable auto equalization.

Gefen has specifically engineered their products to work with the TIA/EIA-568-B
specification. Please adhere to the table below when field terminating cable for
use with Gefen products. Failure to do so may produce unexpected results and
reduced performance.
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
for best results.
Each cable run must be one continuous run from one end to the other. No splices
or use of punch down blocks.
