A. Transceiver installation steps
To install the FGR-HT 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-820181531119 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 Diagnostic 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 configuration.
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. (RF Xmit
Power. Menu 3 > Option 5, when using HyperTerminal for radio setup.)
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
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 is shown below:

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 FGR-HT FreeWave
transceivers at given antenna gain (10 dB and 6 dB Yagi antennas are given as an example)
and cable loss combinations.
NOTE: It is the installer’s responsibility to ensure that the emission limits are not
exceeded.
Table 2 below shows how the RFXmitPower settings on the radio correspond to the EIRP of
the transceiver-cable-antenna combination for the 10 dB Yagi antenna at different cable loss
values.
Shaded area indicates combinations where EIRP limitations exceed FCC regulations
and RF Xmit Power must be reduced.

Table 3 below is similar to the Table 2, but shows the information for the 6 dB Yagi antenna.
Follow the steps below to configure the Power Output Level:
9Start HyperTerminal or equivalent emulation program on the computer connected to the
transceiver’s Diagnostic port. (Refer to the FGR User Manual for the HyperTerminal
setup instructions). EZConfig may also be used to configure the FGR-HT transceiver.
(Refer to the EZConfig user manual for further use of the software.)
9Invoke the setup menu on the transceiver.
9Choose option number “3” from the Main Menu which appeared on the “Hyper Terminal”
window.
9Choose option number “5” from the “Radio Modem Parameters” menu followed by the
appropriate RFXmitPower value, as defined from the previous tables.
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 5 dB for omni-directional and 10 dB for directional
antenna;
•overall system EIRP does not exceed 36 dBm.
WARNING: Any antenna other than listed in this section needs to be approved by
FreeWave Technologies before its use 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.
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 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.
C. Board Level Pin Assignments
The board level transceiver uses standard TTL polarity and voltage levels for all of the signal lines
(Data Terminal Ready, Transmit Data, Receive Data, Carrier Detect, Request to Send, and Clear
to Send).
Pin Signal Assignment Color on ACS3610xx
cable
1 Input B+ input Red
2 Input Interrupt (temporarily ground to invoke
menu) Brown
3 Input Data Terminal Ready (DTR) Orange
4 Ground Black
5 Output Transmit Data (TXD) Yellow
6 Ground Black
7 Input Receive Data (RXD) Green
8 Output Carrier Detect (DCD) Blue
9 Input Request to Send (RTS) Violet (purple)
10 Output Clear to Send (CTS) Gray
Note: Pin 1 on most all of the FreeWave board level transceiver is the pin farthest
from the three LED’s and pin 10 is closest to the LED’s. The exception to this
rule is the “Mini” footprint where pin 1 is closest to the center of the board
(near the RF connector) and pin 10 is toward the corner of the board.
Diagnostic ports:
The FGR-HT will use 1 of 2 Diagnostic cables to configure the radio. The board level Transceiver
will use FreeWave part number ASC2009DC for the serial communication to the Diagnostic port.

Note: Photos are representative of FGR-HT devices.
D. Power Connection
The FGR-HT 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 1.2 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.
