A. Transceiver installation steps
To install the FGR2 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- 42182112519 are to be installed
professionally in NEMA enclosures.
2. Install the antenna and connect the antenna feed-line to the transceiver. If installing a
directional antenna, preset the antenna’s direction appropriately. The antenna must be
professionally installed on a fixed-mounted permanent outdoor structure for satisfying RF
exposure requirements.
3. Connect the serial port of 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. However, there is one parameter that must be
considered for a new installation – the transceiver’s power output setting. Transceiver
output power level must be set according to the tables given below to satisfy the 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
approved by FreeWave Technologies with comparable performance parameters. FreeWave
Technologies offers a variety of Omni-directional 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 are shown below:

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, as shown on the “Hyper Terminal”
window.
Choose option number “5” from the “Radio Modem Parameters” menu followed by the
settings an appropriate RFXmitPower value, as defined above. The RFXmitPower setting
may vary from site to site due to differing antennas and/or cable type or length.
6. Repeat the steps above for each transceiver in the network.
NOTE. Please, be advised that antennas other than listed in this section can potentially be used
with the transceiver provided that:
• these antennas are of a similar type to the listed above;
• antenna gain does not exceed 5dB for Omni-directional and 11dBi for directional antenna;
• overall system EIRP does not exceed 36dBm.
WARNING: Any antenna other than listed in this section needs to be approved by
FreeWave Technologies before it is used to assure that the transceiver in combination
with the new antenna meets FCC requirements.
B. Transceiver Location
Placement of the FreeWave transceiver is likely to have a significant impact on its performance.
With regard to FreeWave transceivers generally, 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 Omni-directional
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.

5 Output TXD (Transmit Data)
6 Ground
7 Input RXD (Receive Data)
8 Output CD (Carrier Detect)
9 Input RTS (Redy to Send)
10 Output CTS (Clear to Send)
Note: Pin 1 board level transceiver is the pin farthest from the three LEDs and pin 10 is closest to
the LEDs.
D. Power Connection
The FGR2 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.
