Installation Manual
The FreeWave Technologies 2.4 GHz I-Series transceivers operate in substantially the same
manner as the 900 MHz DGRO9 radio transceiver module. They may be operated in Point-to-
Point, Multipoint, and Repeater modes.
The one difference is that all I-Series transceivers must be installed professionally.
-Series transceiver installation steps
To install the I Series transceiver, follow the basic steps given below.
1. Mount the transceiver to the flat, stable surface using mounting holes in the corners of the
transceiver.
2. Install the antenna and connect the antenna feedline to the transceiver. If you are installing a
directional antenna, preset the antenna’s direction appropriately.
3. Connect a computer to the transceiver’s RS232 port (please, refer to the part D of this
addendum for more information about the transceiver’s pin assignment). This computer will
be used to set the radio’s configurations.
4. Install the power for the radio.
5. Set the radio configuration according to the system topology and data terminal equipment
requirements. Default transceiver settings allow user to do a quick installation without major
changes in transceiver’s configuration. But there is one parameter that must be considered
for a new installation transceiver’s power output settings.
Transceiver output power level must be

Per FCC regulations maximum permissible EIRP of the communication devices in the 2.4
GHz frequency band is limited differently depending on the communication system
configuration (Point-to-Point or Point-to-Multipoint). Therefore, please be advised that it is
installer responsibility to ensure that the I-Series transceivers installed according to
the guidelines listed below depending on the system configuration. It is also installer’s
responsibility to assure that the emission limits are not exceeded.
WARNING: Any antennas placed outdoors must be properly grounded. Use extreme
caution when installing antennas and follow all instructions included with the
antennas.
The output power of the I-Series radio transceivers can be adjusted by changing “RFXmit
Power” settings on the radio. Table below shows correlation between the “RFXmit Power”
settings and output power of the transceiver.

Required “RFXmit Power” settings for each of the antennas provided by FreeWave are given
in the next section of this document. To configure the Power Output Level from the
transceiver follow the steps below:
ü Start “Hyper Terminal” program on the computer connected to the transceiver’s RS232
port (refer to the User Manual for the “Hyper Terminal” setup instructions).
ü Press setup switch on the I-Series transceiver.
ü Choose option number “3” from the Main Menu which appeared on the “Hyper Terminal”
window.

C. Transceiver Location
Placement of your I-Series FreeWave unit is likely to have a significant impact on its
performance. In general the rule of thumb with FreeWave is that the higher the placement of the
antenna the better the communication link - height is everything! In practice you should also
place the transceiver away from computers, telephones, answering machines, and other similar
equipment. To improve the data link, FreeWave Technologies offers directional and
omnidirectional antennas with cable lengths ranging from 3 to 200 feet.
When using an external antenna, placement of that antenna is critical to a solid data link. Other
antennas in close proximity are a potential source of interference; use the Radio Statistics to help
identify potential problems. It is also possible that slight adjustments in antenna placement (as
little as 2 feet) will solve noise problems. In extreme cases, such as when the transceiver is
located close to Pager or Cellular Telephone transmission towers, FreeWave offers a band pass
filter to reduce the out of band noise.
The I-Series does not provide protection against water or environmental hazards, and will fade
when placed in direct sunlight. For outdoor applications I-Series may not be used. Please,
contact FreeWave Technologies for more information in this respect.

E. Power Connection
The I-Series transceiver can be operated from any well-filtered 9.5-30 VDC power source. The
power source should be capable of providing at least 0.6 amperes of continuous current.
Transceiver is designed to operate in negative ground systems only
