Transceiver Installation Overview
Transceiver Installation Overview
To successfully install a transceiver, follow the basic steps listed below.
1. Determine the best location for the transceiver.
2. Install the ground rod.
3. Install the NEMA 4 enclosure
4. Mount the transceiver and power supply into the enclosure.
5. Route data cables to the end device.
6. Connect power and configure the transceiver.
7. Install the antenna.
8. Connect a surge suppressor between the external antenna cable and interior cable connected to
the transceiver's RF connector..
9. Waterproof all external connections.
Choosing a Location for the Transceiver
Placement of the FreeWave transceiver is likely to have a significant impact on its performance. The key to
the overall robustness of the RF link is the height of the antenna. 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. In general, FreeWave units with a
higher antenna placement will have a better communications link. In practice, the transceiver should be
placed away from computers, telephones, answering machines, and other similar devices. FreeWave
Technologies, Inc. offers directional and Omni directional antennas with cable lengths ranging from 3 to
200 feet.
The Show Radio Statistics page is found in option 4 in the main terminal menu or in the Diagnostic information
in Tool Suite. An adjustment as little as 2 feet in antenna placement may resolve some noise issues.
Installing the NEMA Enclosure
The NEMA enclosure selected for the installation site should be a NEMA-4 rated enclosure. NEMA 4
enclosures are gasketed and the door is clamped for maximum sealing. NEMA 4 enclosures are available in
sizes from small wall mounts to two-door floor mount models. The selection depends on the requirements of
the particular installation and the amount of equipment to be placed inside.
Follow the installation instructions provided with the NEMA enclosure, ensuring that no holes are drilled on the
top of the enclosure. Holes on the top of the enclosure can allow moisture and other elements into the
enclosure. Ensure holes on the sides and bottom are waterproofed.
Mounting the Transceiver in the NEMA Enclosure
FreeWave transceivers have several mounting options including metal plates, din rail clips, and brackets.
When mounting any transceiver, ensure that it is mounted to a flat, stable surface using the mounting bracket
or the mounting holes in the corners of board-level transceivers.
LIG0002AC Rev G
2.4 GHz Wireless Data Transceivers
Warning! Do not use Velcro to mount the transceiver. Attaching and detaching Velcro
pieces creates an electro-static discharge that may damage the transceiver's circuitry,
or other electronic devices nearby. Mounting a transceiver to a metal surface may
result in an electrical short across the transceiver. Removing Velcro also creates
stress points on board-level transceivers with a great potential to damage the solder
points.
Ruggedized Gannet Enclosure Din Rail Mounting Instructions (MBRKDIN-N)
The FreeWave MBRK-DIN-N Din Rail Mounting Bracket Kit is available to mount transceivers in the dark
gray ruggedized Gannet enclosure. The mounting kit ships with the following hardware:
1 - Din rail mount
2 - 6-32 x 1/4 inch truss head screws
Depending on the din rail setup, it may be helpful to note the transceiver's serial number and any other
information needed from the transceiver's label. The transceiver snaps out of the mount if you require access
to the label information at a later time.
1. Slide the din rail mount over the rear of the
enclosure, ensuring the din rail mount is correctly
oriented so the cut outs for the feet match up with
the feet on the transceiver.
2. Align the holes on the din rail mount with those on
the transceiver. Secure the transceiver to the din
rail mount using the truss head screws provided.
3. Attach the transceiver in its din rail mount to the din
rail.
The din rail mount is designed to allow the
transceiver to be fitted with the LEDs facing to the
left or the right. The only difference is the location of
the release catch either at the top or at the bottom.
To remove the assembly from the din rail mount, insert a small screwdriver into the leverage point on the end
of the release catch and push down lightly approximately 0.25 inches (12.70 mm). The clamp releases and the
assembly can be lifted off.

2. Attach the standoffs to the front side (non-flat side) of the transceiver with four screws.
3. Align standoffs with the bracket holes and secure with the other four screws.
Powering the Transceiver
To provide power to the transceiver, connect it to a power supply that meets the specifications outlined in the
product's data sheet and the product's user manual.
For any application where the transceiver is used in a UL-controlled environment, the power supply must be a
Class 2 power source. Use a dedicated power supply line.
Important: GX-C, GX-CE, and GX-T transceivers are UL approved for use between
+6.0 to +30.0 VDC. However, for guaranteed performance, FreeWave recommends
using between +7.5 to +30.0 VDC to power the transceiver.
If the power supply line runs outside the enclosure, use electrostatic discharge (ESD) protectors to protect the
transceiver from electric shock, and transient voltage suppressors (TVS) to protect from an over-voltage
LIG0002AC Rev G
Configuring the Transceiver
situation. Using both helps enhances reliable operation and can be purchased at most electronic supply
stores.
Warning! If the power supply is above +18.0 VDC, use a 1 ohm resistor inline with
power input to the transceiver. For more information, see application note #5467:
Power Wiring Precaution for FGR-Series at High Supply. The cautions outlined in the
application note also apply to the GX family transceivers.
Configuring the Transceiver
A standard network requires that the following parameters are set the same on all transceivers in the network:
Frequency Key
Hop Table Version
Hop Frequency Offset
Min Packet Size
Max Packet Size
Network ID
RF Data Rate
Transceivers that contain the same settings in all the parameters above can communicate with each other. If
you choose to use the Call Book instead of the Network ID, or the network is a Point-to-Point network, the
Call Book must include the appropriate serial numbers for each transceiver. If the network contains parallel
Repeaters, the Frequency Key setting may differ.
In addition, set the Transmit Power parameter to the appropriate setting based on the cable loss in your
installation. For more information, see "Cable Loss and Transmit Power Settings" на стр.13.
Use a terminal emulator of your choice to access the Setup menu. For any terminal emulator application, plug
the serial cable into a COM port on the transceiver, open a session, and ensure that the port settings are set to
the following for a proper connection to the transceiver:

Installing the Antenna
Antennas must be professionally installed on a fixed, mounted, and permanent outdoor structure to satisfy RF
exposure requirements.
LIG0002AC Rev G
11
Installing the Antenna
Warning! Any antenna placed outdoors must be properly grounded. Use extreme
caution when installing antennas and follow all instructions included with the antenna.
Per FCC regulations, any antenna used with FreeWave transceivers must be an approved antenna that has
comparable performance parameters. For more information about approved antennas, see "Approved
Antennas" на стр.11.
When installing an antenna on a pole or tower, ensure the installation complies with the following
requirements:
If there are multiple antennas installed on the same pole or tower, ensure there is at least 10 feet
(3.048 meters) vertical separation between antennas on the structure. Installing antennas too
close to one another, even if they are of different frequencies, maycause the energy from one to
interfere with the other.
If the antenna is mounted parallel to the pole or tower, ensure there is at least 18 inches (46 cm)
standoff between the structure and the antenna itself. Installing the antenna too close to the
structure to which it is mounted may cause the energy being transmitted from the antenna to
interfere with the antenna itself.
If you are installing a directional antenna, set the antenna's direction appropriately. If the antenna
has a moisture weep hole, ensure the antenna is mounted so the weep hole faces down to drain
water.
Run extra cable at the top of the installation for stress relief (see the illustration below).
Include a drip loop of cable at the bottom of the installation that is lower than the NEMA enclosure
(see the illustration below). This loop allows moisture to run off the cable to the ground.
In addition, ensure your installation has the following components and that they are installed according to the
manufacturer's installation instructions:
8 foot ground rod.
Bulkhead mount surge suppressor.
LIG0002AC Rev G

2.4 GHz Wireless Data Transceivers
Cable Loss and Transmit Power Settings
The Transmit Power parameter is the output power of the transceiver. The transceiver output power level
must be set to satisfy maximum Effective Isotropically Radiated Power (EIRP) requirements in the country in
which the installation exists.
LIG0002AC Rev G
13
Cable Loss and Transmit Power Settings
When setting up the network, consider the power gain that an antenna may add, and the power loss through
cabling. Adjust the Transmit Power on the transceiver to ensure that you do not exceed the maximum EIRP
for the regulating body where the installation exists. Use the tables below to determine the correct Transmit
Power parameter setting for each transceiver in the network.
Important: The information in this section discusses FCC and ETSI maximum EIRP
regulations. Ensure your installation meets the maximum EIRP requirements for the
country in which you are installing transceivers. It remains the installer's responsibility
to ensure that an installation is within EIRP emission limits.
The FCC permits 27 dBm (0.5 Watt) output power at the transceiver and 36 dBm (4 Watts) at the antenna.
ETSI permits a total of 20 dBm (100 mW) total, which includes the output power at the transceiver and the
antenna gain.When calculating the power gain, use the following equation to determine the total output power
at the antenna. Loss calculations should include cable, connectors, surge protectors, and so on.
Transceiver Output – Losses + Antenna Gain = Output Antenna Power
For example, 30 dBm – 2 dB + 6 dB = 34 dBm (or 2.5 Watts). 34 dBm is within the FCC limits. However,
30 dBm – 2 dB + 10 dB = 38 dBm (or 6.3 Watts) exceeds the FCC limits. Neither is permitted under ETSI
regulations.
The following table shows the RF loss at various cable lengths:

In GX family transceivers, the Transmit Power parameter settings range from 0 dBm to 27 dBM (1 mW to
500 mW). The maximum transmit power is capped at 20 dBm at the factory to comply with ETSI regulations
for countries that require it, or capped at other values to comply with country-specific requirements.
The output power can vary slightly between transceivers; however, the output power never exceeds 27 dBm
(500 mW).
The following table provides the maximum Transmit Power parameter setting for FreeWave transceivers at a

Note: Networks using 2.4 GHz transceivers exclusively for fixed, Point-to-Point
operation may employ transmitting antennas with directional gain greater than
6 dBi, provided the maximum peak output power of the intentional radiator is
reduced by 1 dB for every 2 dB that the directional gain of the antenna exceeds
6 dBi.
This excludes the use of a Point-to-MultiPoint system, omni-directional
applications, or multiple co-located intentional radiators transmitting the same
information.
Waterproofing External Connections
After you have installed all the components at the site, waterproof all exterior connections with a moldable
plastic coax sealant or using mastic tape and an electrical coating. Ensure that each connection in the
installations is thoroughly sealed.
Moldable coax sealant and other electronic waterproofing supplies are available at most electronic supply
stores. Follow the installation instructions provided with the product to ensure a proper waterproofed seal.

Board-Level and DB9 Pinouts
The information in the following sections provides the pinout connection information for the connectors on the
transceivers.
RF Board Level Pinout
The board-level transceivers are available in both TTL and RS232 versions. The TTL version uses reverse
polarity from standard RS232 at 0 to 5 Volt levels. All pin descriptions and pin numbering are the same as the
RS232 version. The RS232 version 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) and TTL standard
polarity and voltage level for the Interrupt pin.
Pin 1: B+ Power input.
Pin 2: Interrupt (INT) – Input – A 0 Volt level on this pin switches the transceiver into Setup mode.
Pin 1 on the board-level transceiver is the pin farthest from the three LEDs and pin 10 is closest to the LEDs.

Signal return for all signal lines shared with Pin 9.
Output
Always high when the transceiver is powered from the 2.5 mm
power connector. Indicates power is on to the transceiver. Also,
this pin can be used for +12.0 Volts when powering the
transceivers directly through the RS232 port.
Note: This is not used on the OEM module.
RTS
Request to
Send
Input
The transceiver does not recognize RTS for flow control. RTS is
used as a control line in RTS/CTS mode.
CTS
Clear to
Send
Output
This signal is used to tell the system device connected to the
transceiver that the transceiver is ready to receive data. When
asserted, the transceiver accepts data, when de-asserted the
transceiver does not accept data. This should always be used for
data rates above 38.4 KB or a risk of lost data may occur if an RF
link is not very robust.
