FreeWave Technologies I-Series User Manual Addendum Installation Manual V1.0a 1 FreeWave Technologies, Inc. I-Series Radios User Manual Addendum 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 satisfy FCC maximum EIRP requirement depending on the antenna used, antenna cable loss FreeWave I-must be provided by FreeWave Technologies. FreeWave l external antennas, with both bracket and magnetic mounts. The complete list of antennas available from FreeWave characteristics is given in the table below.

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.

FreeWave Technologies I-Series User Manual Addendum Installation Manual V1.0a 7 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.
