• Do not operate the transceiver unless all RF connectors are secure and any open connectors are properly
terminated.
• Avoid contact with the antenna while operating the transceiver.
• Do not operate the transceiver with a damaged antenna. If a damaged antenna comes in contact with
the skin, a minor burn may result.
• Do not operate the equipment near electrical blasting caps or in an explosive atmosphere.
CAUTION – Changes or modifications not expressly approved by the FCC could void the user’s authority to

FCC Rules and Regulations
Licensing requirements
It is the responsibility of the owner to comply with applicable rules and regulations concerning the
operation of a radio transmitter. In the United States, the FCC regulates the licensing of this equipment.
Application for a license is made by submitting FCC Form 600 along with evidence of frequency
coordination (if required) and applicable fees. Similar licensing requirements exist worldwide. Penalties for
broadcasting without a license can be severe, and may include the confiscation of your radio.
For more information, contact our customer service department.
WARNING – Always obey local licensing requirements and restrictions. It is illegal to transmit in the United
States while CSMA is turned off. CSMA is not required within the European Union and should be turned off.
Equipment compliances
The radios have been tested and found to comply with Parts 15 and 90 of Title 47 of the Code of Federal
Regulations. They have also been tested and found compliant for type certification and approval in many
other countries worldwide.
For more information concerning our worldwide compliances, contact customer support.
Being part of the RF community
Operation of a licensed radio product makes you a member of the RF community. Be aware that virtually all
frequencies licensed are provided on a shared basis with other users. Each frequency dedicated specifically
to RTK surveying activities has certain restrictions and limitations. For complete information, refer to the
appropriate documentation from the licensing agency in your country of operation, e.g., Part 90, Title 47, of
the Code of Federal Regulations.
Most frequencies sharing data transmissions and voice transmissions give priority to voice users. Be
mindful of the persistent nature of a GPS RTK data transmission and always limit your RF transmission
output power when performing close-in survey situations to avoid interference with co-channel users.
Trimble recommends using the low RF power setting for construction site and other line-of-site surveys
with baselines less than two miles (depending on terrain).
WARNING – If you are in conflict with a co-channel user, select another frequency to avoid formal actions
by government agencies. In most cases, you are required to vacate a frequency upon complaint by a shared
channel voice user.
Most survey operations are itinerant in that the system is moved on a frequent basis. For fixed system
TDL 450i Intergrator’s Guide 6
installations, you should not use frequencies set aside for itinerant operations, but should coordinate a
frequency based on the fixed area operation.
Regulations differ from country to country, please be aware of the local regulations before using radio
equipment.
Automatic station identification
For operation in the United States, the FCC requires that radio transmitters broadcast a station identifier
every 15 minutes. The station identifier is the call sign assigned to you on the station license.
The radios support the broadcast of station identification in a manner that meets the requirements of
the FCC. Upon receipt of equipment, use the XDLCONF software to program your FCC call sign into the
configuration of the radio. This is only required for transmitters.
The call sign is transmitted every 15 minutes in Morse code. It is not included in any data packet and so is
not processed by the receiving radio. However, data transmission is interrupted for a few seconds while the
call sign is being transmitted. If you leave the Call sign field blank (on the XDLCONF Identification screen),
the radio programmed with this configuration file will not transmit any call sign.
WARNING – Failure to transmit your station identification is in violation of FCC regulations. If you are
operating outside the United States, check with the local authorities if you need to transmit a call sign.
Carrier Sense Multiple Access (CSMA)
CSMA is a technology implemented in the radios to meet the United States Federal Communication
Commission (FCC) transmitter requirements. It is illegal to transmit on any UHF radio within the United
States without CSMA enabled. CSMA holds off the radio transmission if the frequency is currently being
used by a co-channel user. On occasion, you may note that the radio broadcasts stop for short periods of
time. Most often, this is a case of co-channel interference and the radio is holding off broadcasts due to the
FCC-mandated CSMA.
Note – You should turn CSMA off when transmitting within the European Union.
GPS RTK equipment is designed to function with intermittent gaps in the data. Heavy co-channel use may
limit the ability of the radio to transmit the required information. In areas of heavy co-channel usage, try
changing channels to a less used frequency.

TDL 450i Intergrator’s Guide 13
Electrical Considerations
Power Supply
The TDL 450i transceiver has a power supply connection on Pin 18 and Pins 23 to 28 of the interface
connector. Pins 1, 5,7, 9,30 and Pins 19 to 22 are connections to both power ground and serial interface
signal grounds. Note that these pins are tied to a common point on the TDL 450i transceiver. If there is a
potential for a ground path current loop due to improper power application, we recommend a fusible link
be inserted in the signal ground to protect the TDL 450i transceiver.
TDL 450i transceiver modems are designed to operate with unregulated DC voltage levels between 3.6 and
4VDC. The power supply must be capable of sourcing 2A.
Data Interface
TDL 450i transceiver provides one data port, which has a simple 3-wire CMOS electrical interface with
signals for transmitting data to and receiving data from the TDL 450i transceiver, and for providing a
reference ground for the TX (Pin 3) and RX (Pin 14) signals.
Note: We define TX and RX as a DTE port. In other words, an external device transmits data to the radio
modem’s TX pin (Pin 3) and receives data from the radio modem’s RX pin (Pin 14).
CMOS Input/Output Protection Circuitry
The TX signal terminates into a CMOS input port on the TDL 450i transceiver and should be driven
externally or pulled to ground through a 10 kΩ resistor. The absolute maximum voltage applied to the TX
signal is -0.3 V to 3.3 V.
The signals are CMOS outputs. Note that loading the RX signals increases the power consumption of the
TDL 450i transceiver and these should be limited to no more than 2.5 mA each to maintain performance
across the temperature range.
Caution: Internal circuitry protects the inputs and outputs against damage caused by high static voltages or
electric fields; however, normal precautions are necessary to avoid application of any voltage higher than the
maximum-rated voltages.
TDL 450i Intergrator’s Guide 14
Error Codes
The TDL 450i transceiver performs a variety of power-up and run-time tests to assure optimal operation.
Tests include environmental as well as electrical measurements designed to avoid damage to the unit while
maintaining adequate operation.
A 50Ω impedance coaxial MMCX style RF connector is provided for attachment to an external antenna
system. The MMCX connector offers a positive friction locking mechanism that is very reliable. In some
circumstances, it may be required to provide a physical stop to prevent the MMCX plug from becoming
disconnected due to extreme shock or vibration.
The TDL 450i transceiver requires an antenna and feed cable system that is impedance- matched to 50Ω.
We recommend that high quality RG-178 or equivalent coaxial cable be used for internal wiring of the RF
signal from the MMCX to the panel connector. We also suggest the selection of an antenna that has a low
VSWR (less than 1.5:1) and that has been tuned for operation in the band of the TDL 450i transceiver.
Caution: Improper impedance matching of the antenna, connectors or cable will degrade the performance of
the TDL 450i transceiver.
Shielding Considerations
The TDL 450i transceiver is designed to operate in proximity to noise generating circuitry. However, certain
radiated or conducted frequencies may degrade the performance of the TDL 450i transceiver or render it
inoperable. When possible, provide well-grounded shielding between circuits that radiate, such as power
supplies, voltage-controlled oscillators, crystal oscillators and the TDL 450i transceiver.
Frequency Planning
The TDL 450i transceiver contains a very sensitive, dual-conversion super-heterodyne receiver.
Caution: Radiated and conducted signals to and from the TDL 450i transceiver may cause problems due to
interference. Proper attention to frequency planning may reduce interference from radiated or conducted
frequencies that fall within the pass-bands of the filters at the IF frequencies.
We recommend the use of upfront analysis of the product frequency plan (including harmonics) and then
the use of a spectrum analyzer to determine the potential for interference within the pass-bands of the
various front-end and band pass filters.
The following table indicates the frequencies and band pass filter characteristics that are areas of potential
interference.

Mechanical Considerations
EMI interferers
The TDL 450i transceiver is easily mounted inside new and existing products. The TDL 450i
transceiver is specifically designed for operation in harsh environments. For best performance,
mount the radio away from potential EMI radiators and route RF signals apart from digital signals.
Caution: We do not recommend the bundling of the antenna interface cable with other signal cables
internal to your product.
Shock and Vibration
Sensitive radio transceivers, such as the TDL 450i transceiver, are susceptible to interference due
to mechanical shock and vibration. To reduce the potential for electromechanical interference, a
robust mounting scheme must be used when being integrated into other systems. A thin damping
pad between the mounting surface and the TDL 450i transceiver may be required. We recommend
the use of damping pads made of PORON(R) or a similar material.
Thermal Transfer
The TDL 450i transceiver requires additional thermal heat dissipation in order to supply maximum
power out at elevated ambient temperatures and high duty cycles. The TDL 450i transceiver has
a thermal sensor and a firmware controlled limit switch. The TDL 450i will shut down when the
PCB temperature reaches 85°C to prevent permanent damage to transmitter. The integrated heat
sink is adequate for most bench top testing but when the TDL 450i transceiver is integrated into
other systems additional thermal heat sinking must be considered. The TDL 450I will produce
TDL 450i Intergrator’s Guide 16
approximately 6 Watts of heat at full RF power out.
Refer to Appendix A for mounting diagrams and specification.
Materials
The TDL 450i transceiver is housed in a metal shield that is a conductor and is electrically connected to the
ground and signal ground pins.
