Gefen products or any devices that use the RS-232 serial control interface.

How It Works

Simply connect the Gefen Wireless RS-232 Extender Sender unit to a computer
(or other RS-232 control device) using the supplied RS-232 serial cable. Connect
the Receiver unit to the device being controlled using another RS-232 cable.
Select the correct baud rate (either 9600 or 19200) on both the Sender unit and
Receiver unit, using the DIP switch bank on the bottom of both units. Connect
the included 5V DC power supplies to both the Sender unit and Receiver unit.
The Gefen Wireless RS-232 Extender will connect a computer wirelessly to the
device attached to the Receiver unit, as if the RS-232 host device were attached

directly to the client.

FCC STATEMENT AND INDUSTRY CANADA STATEMENTS

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

INSTRUCTION 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 modications made to the equipment without the
approval of the manufacturer could void the user’s authority to operate this
equipment.
