FCC Notification
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.
This device must be operated as supplied by FreeWave Technologies, Inc.
Any changes or modifications made to the device without the express written
approval of FreeWave Technologies may void the user's authority to operate
the device.
CAUTION: This device has a maximum transmitted output power of 955mW. It is
required that the transmit antenna be kept at least 23 cm away from
nearby persons to satisfy FCC RF exposure requirements.
Note: 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.
♦ Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
♦ Consult the dealer or an experienced radio/TV technician for help.
Note: Whenever any FreeWave Technologies module is placed inside an enclosure a label
must be placed on the outside of that enclosure which includes the module's FCC ID.

A. Transceiver installation steps
To install the DGR and FGR series transceivers, follow the basic steps given below.
1. Mount the transceiver to the flat, stable surface using mounting holes in the corners of the
transceiver. Transceiver models sold under FCC ID KNY-6231812519 are to be installed
professionally in NEMA enclosures.
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. The antenna must be
professionally installed on fixed-mounted permanent outdoor structures for satisfying RF
exposure requirements.
3. Connect a computer to the transceiver’s RS232 port (please refer to the part C 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 set according to the tables given below to satisfy
FCC maximum EIRP requirement. Per FCC regulations, any antenna used with FreeWave
transceivers must either be one of the approved antennas shown below or an antenna with
comparable performance parameters.
FreeWave Technologies offers a variety of
omnidirectional and directional external antennas, with both bracket and magnetic mounts.
The complete list of antennas available from FreeWave Technologies including antenna
gains, antenna manufacturer’s information and antenna’s characteristics is shown below:

Note1. This antenna is approved for the usage with the transceivers, but may not be
available for sale directly from FreeWave Technologies. Contact FreeWave
Technologies for more details.
WARNING: Any antennas placed outdoors must be properly grounded. Use extreme
caution when installing antennas and follow all instructions included with the
antennas.
Table 1 below provides the maximum output power settings for FreeWave transceivers at
given antenna gain (10 dB and 6 dB Yagi antennas are given as an example) and cable loss
combinations. Please note that it is the installer’s responsibility to ensure that the
emission limits are not exceeded.

Follow the steps below to configure the Power Output Level:
Start HyperTerminal or any other terminal emulation program on the computer connected
to the transceiver’s RS232 port (refer to the User Manual for the HyperTerminal setup
instructions).
Invoke the setup menu on the transceiver.
Choose option number “3” from the Main Menu which appeared on the “Hyper Terminal”
window.
Choose option number “5” from the “Radio Modem Parameters” menu followed by the
settings an appropriate RFXmitPower value, which was defined from the previous
transceiver installation procedure.
6. Repeat the steps above for each transceiver in the network.

B. Transceiver Location
Placement of the FreeWave transceiver 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 or
Diagnostics software 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.
C. Board Level Pin Assignments
The board level transceiver uses standard RS232 polarity and voltage levels for all of the RS232
signal lines (DTR, Transmit Data, Receive Data, Carrier Detect, RTS, and Clear to Send).
Pin 1: B+ Power input.
Pin 2: Interrupt (INT) – Input – A 0 volt level on this pin will switch the radio into setup mode.

Note: Pin 1 on the DGRO9 board level transceiver is the pin farthest from the three
LEDs and pin 10 is closest to the LEDs.

D. Power Connection
The DGR and FGR series transceivers can be operated from any well-filtered DC power source,
input voltages vary by model. The power source should be capable of providing at least 0.8
amperes of continuous current. The pin #1 of the 10-pin connector on the transceiver is the
positive lead; pin #4 or pin #6 of this connector should be as a negative lead.
Transceiver is designed to operate in negative ground systems only.
