FCC Statement
INSTRUCTIONS TO THE USER
This equipment has been tested and found to comply with the limits for a class B digital
device, pursuant to part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This
equipment generates, uses and can radiate radio frequency energy and if not installed
and used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the user
is encouraged to try to correct the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna
• Increase the separation between the equipment and Receiver unit
• Connect the equipment into an outlet on a circuit different from that to which the
Receiver unit is connected
• Consult the dealer or an experienced radio/TV technician for help.
In order to maintain compliance with FCC regulations, shielded cables must be used with
this equipment. Operation with non-approved equipment or unshielded cables is likely to
result in interference to radio and TV reception. The user is cautioned that changes and
modications made to the equipment without the approval of the manufacturer could void
the user’s authority to operate this equipment.
This device complies with part 15 of the FCC Rules. Operation is
subject to the following two conditions: (1) This device may not cause
harmful interference, and (2) this device must accept any interference
received, including interference that may cause undesired operation

Applicant’s Name: Gefen, LLC
Manufacturer’s Trade Name: Gefen
Model / IC ID Numbers:
EXT-WRS232R (IC:9057A-EXTWRS232R)
EXT-WRS232S (IC:9057A-EXTWRS232S)
The wireless radio of this device complies with IC RSS-210 Industry Canada. Operation is
subject to the following two conditions: (1) this device may not cause interference,and (2)
this device must accept any interference, including interference that may cause undesired
operation of the device.
To reduce potential radio interference to other users, the antenna type and its gain should
be so chosen that the equivalent isotropically radiated power (EIRP) is not more than that
required for successful communication.
This device has been designed to operate with the antennas provided, and having a
maximum gain of 2.5 dBi. Antennas not included with this product or having a gain greater
than 2.5 dBi are strictly prohibited for use with this device. The required antenna impedance
is 50 Ohms.

Operating Notes
Important Operating Information
• The Wireless RS232 Extender is capable of operating at a baud rate of either 9600
or 19200. See Setting the Baud Rate for details on setting the correct baud rate for
the RS-232 device.
• The metal housing is immune to EMI interference and the external antenna is capable
of extending RS-232 control up to 100 feet (30 meters) through 8 brick walls. Multiple
Sender units can also operate simultaneously, allowing greater exibility in a wireless
RS-232 solution. See the Conguration section ror details on setting up a wireless
RS-232 network.
• Although the Sender unit can be used without external power, the RS-232 protocol
does not outline specic guidelines for sending power to another RS-232 device.
In most cases, only a small amount of power can be extracted (~10mA) from the DTR
(Data Terminal Ready) and RTS (Ready To Send) lines. This is only suitable for lower
power devices (e.g. mouse devices). If there is not enough available power, the LED
stays in the OFF state.
• After changing DIP switch settings on a Sender and/or Receiver, disconnect the
power and RS-232 cables from each unit, then reconnect them. Failure to do so may
prevent the changes from taking effect or may result in erratic behavior.
