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

Antenna installation requirements This section describes what settings can be used on the I-Series transceiver if one of the provided by FreeWave Technologies antennas is used. B.1. “Maxrad” MSP24013MB antenna. The gain of this antenna depends on the beamwidth selected during the installation. Below is the table showing the dependency between the selected beamwidth of the antenna and its gain.

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.
