Introduction
Overview
DUHFII is a half duplex, UHF Radio Modem with built-in GSM/GPRS (or CDMA, HSPA) module
and Bluetooth transceiver developed to be integrated in a Topcon receiver. It takes incoming data from
a Topcon receiver through the standard serial port (CMOS/TTL compatible), modulates it with GMSK,
or 4FSK modulations and transmits it at RF power output levels from 10mW/10dBm to 1W/30dBm.
With 4FSK modulation, it will deliver error-free data at up to 19.2 kbps over the air for the 25 kHz
channel spacing and 9.6 kbps for 12.5 kHz.
The carrier frequency is the UHF commercial band of 400 MHz to 470 MHz. Channel spacing at 25
kHz, 20 kHz and 12.5 kHz are supported. The UHF transceiver is also capable of receiving RF signals
through a 50 Ohm impedance external antenna port. These signals are demodulated and output to the
Topcon receiver.
The modem requires a regulated DC voltage power supply from +6 to +14VDC with a maximum
current draw of 1.1A at 6VDC.
The incoming data could be also sent over the cellular network using built-in GSM/GPRS (or CDMA,
3G) module if such operation mode is selected.
The radio settings can be done through the built-in Command Line interface (CLI), or through the
configuration and maintenance application software running on the PC – “TRU”.
Note: The cell module option is currently not available. References to the cell module option in this
manual are for future configurations that have not been released.

Operating Band, Channel Spacing, and Output
Power
The following are its key benefits:
1. Single radio system covers the whole UHF frequency band from 400 to 470 MHz;
2. User selectable channel spacing (25kHz, 20kHz or 12.5kHz);
3. User selectable Output power level for base unit (10mW/10dBm and 1W/30dBm);
4. Programmable to limit operation to given frequency range or list of channels, given channel
spacing, given output power, RX mode.
Modulation Technique
The design is based on high-level modulation techniques which include:
Physical Interfaces
Serial Data Interface
The serial Data Interface can be configured through the software to operate in half and full duplex
operating modes. RTS, CTS, and CD signals should be reserved on-board for future support of full
UART hardware handshake operation. This will provide the support of the wide range of different
standard and none-standard, user specific, Data Link interfaces.
Modulation Technique 12.5 kHz 25 kHz
GMSK – Minimal Shift Keying with Gaussian Filtering 4.8 kbps 9.6 kbps 4.8 kbps 9.6 kbps
4FSK – Four Level Frequency Shift Keying 9.6 kbps 19.2 kbps 9.6 kbps 19.2 kbps
Physical Interfaces
P/N 7010-xxxx 1-3
Link Status Indicators
External LED’s are used for Link and Line status indication:
Power Interface
The power interface allows connection to an unregulated DC power source. The DC power source
(third party or user supplied) must provide peak 7.0 Watts of DC power between 6 and 14VDC. The
power interface is protected against reverse polarity connection, as well as protected against high-
voltage transients.
RF Interface
The RF interface is a 50-ohm impedance matched standard MMCX connector as required by
regulation. Switching from UHF to GSM/GPRS (or CDMA) operation mode and vice versa is
provided on RF interface.
Bluetooth Interface
Bluetooth antenna connector of Radial UMP series (R107003010) is used for Bluetooth antenna
attachment.
LED Name Color Description
TXA Green Active if modem transmits Data over radio link (min.
light on 200ms)
RXA Red Active if modem receives Data over radio link (min.
light on 200ms)
BLUETOOTH Blue Active if modem receives or transmits Data over
Bluetooth interface
WARNING
Before transmitting, always confirm that the antenna is connected.
Never transmit without the antenna or load connected.
WARNING
Mismatching of impedance between the DUHF II, antenna, and cable will cause a lesser transmit
power and result in a higher VSWR.

Hardware Architecture
Functional Requirements
The UHF Modem/Cell/BT Board consists of the following main sections:
• UHF modem Tx/Rx modem;
• GSM/GPRS, 3G, or CDMA modules;
• Bluetooth module.
The block diagram of the DUHFII is presented below. In the figure, consider GSM modem as referring
to either GSM/GPRS or CDMA modules.
Electromagnetic Compliance
This device complies with part 15 of the FCC Rules. Operation is subject to the condition that this
device does not cause harmful interference.
NOTICE
The GSM/GPRS (or CDMA) module installation is optional. The mechanical design and software tools
provide easy way for GSM/GPRS module optional installation and configuration.
Electromagnetic Compatibility
P/N 7010-xxxx 1-5
Changes or modifications not expressly approved by the manufacturer could void the user’s authority
to operate the equipment.
Installation of Digital UHF II module into device shall comply with section 2.1091 of the FCC Rules.
If not possible to ensure that the separation between the user and the UHF antenna is greater than 30
cm, the user manual shall contain a statement warning the user to stay away from the UHF antenna by
30 cm at least when the UHF radio is operating in transmit mode.
UHF and Bluetooth antennas shall be shielded from the Digital UHF II module by the construction of
the device, so that not to cause harmful interference to the module.
Electromagnetic Compatibility
Shielding Considerations
The DUHF II transceiver is designed to operate in proximity to noise generating circuitry. However,
certain radiated or conducted frequencies may degrade the performance of the DUHF II 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 DUHF II transceiver.
Frequency Planning
Radiated and conducted signals to and from the DUHF II 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.
It is recommended 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.
WARNING
The DUHF II is classified as an intentional radiator of type radio transceiver. Conducted and
radiated emissions of the standard DUHF II transceiver do not exceed the requirements of FCC
part 90. OEM is responsible for full compliance of final product.
WARNING
Frequencies ranging from 403 to 413 MHz may adversely affect GPS L2.
Do not use these frequencies with a Topcon GNSS receiver.
Introduction
Digital UHF II EXTERNAL DESIGN SPECIFICATION
1-6
Mechanical Considerations
EMI interferers
The DUHF II transceiver is easily mounted inside new and existing products. The DUHF II 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.
Shock and Vibration
Sensitive radio transceivers, such as the DUHF II 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.
Thermal Transfer
The DUHF II transceiver requires additional thermal heat dissipation in order to supply maximum
power out at elevated ambient temperatures and high duty cycles. The DUHF II transceiver has a
thermal sensor and a firmware controlled limit switch. The DUHF II will shut down when the PCB
temperature reaches 100°C to prevent permanent damage to transmitter. The DUHF II will produce
approximately 6 Watts of heat at full RF power out.
Materials
The DUHF II transceiver is housed in a metal shield that is a conductor and is electrically connected to
the ground and signal ground pins.
WARNING
It is not recommend the bundling of the antenna interface cable with other signal cables internal
to your product.

Icons
This reference includes icons that appear in the left margin and are designed to help you clearly
identify operating mode in which you can apply a particular command. The following icons are used
throughout this reference:
Operating Modes
The DUHFII modem can be operated in ether of the following modes:
• Factory – This mode is intended for the factory floor only. In this mode, factory personnel can
calibrate the modem and upload the factory firmware image and bootloader to it. The modem
enters Factory mode initially and brings out of this mode after a normal country configuration file
is uploaded.
• Dealer – This mode is intended for the dealers. In this mode, a dealer can load a dealer
configuration file to the modem. This file contains a customized set of parameters that the dealer
have selected to run on the modem. For details about the parameters available in this file, see
“Configuration Files” on page 2-3. The modem enters Dealer mode after a country configuration
file and brings out of this mode after a normal dealer configuration file is uploaded. Once the
modem brings out of Dealer mode, it automatically goes into User mode.
• User – This mode is intended for the end-users. In this mode, a user can apply the parameters
available in the dealer configuration file to the modem. For details about the parameters available
in the dealer configuration file, see “Configuration Files” on page 2-3. Note that every DUHFII
modem shipped to an end-user must be in User mode.

Firmware Images
P/N 7010-xxxx 2-3
Firmware Images
The DUHFII modem stores two firmware images; a factory and a user image.
• The factory image is the factory-installed firmware that is permanently available on the DUHFII
modem.
• The user image is the user-installed firmware that normally controls all modem operations,
including its normal boot process. If the modem boot process with the user image fails for any
reason, the modem can be booted with the factory image.
Initially, the modem is initialized with factory and user firmware images which are identical.
Configuration Files
The DUHFII modem stores three configuration files, specifically: factory configuration file, dealer
configuration file, and country configuration file.
Factory configuration file
This file stores modem calibration parameters and is generated only by the test bench on the factory
floor.
Dealer configuration file
The dealer configuration file limits the selection of frequencies, channel spacings and maximum
output power for an end user. Note that the allowed frequencies are defined by a list of specified
frequencies, not by the range.

Introduction
Overview
DUHFII is a half duplex, UHF Radio Modem with built-in GSM/GPRS (or CDMA, HSPA) module
and Bluetooth transceiver developed to be integrated in a Topcon receiver. It takes incoming data from
a Topcon receiver through the standard serial port (CMOS/TTL compatible), modulates it with GMSK,
or 4FSK modulations and transmits it at RF power output levels from 10mW/10dBm to 1W/30dBm.
With 4FSK modulation, it will deliver error-free data at up to 19.2 kbps over the air for the 25 kHz
channel spacing and 9.6 kbps for 12.5 kHz.
The carrier frequency is the UHF commercial band of 400 MHz to 470 MHz. Channel spacing at 25
kHz, 20 kHz and 12.5 kHz are supported. The UHF transceiver is also capable of receiving RF signals
through a 50 Ohm impedance external antenna port. These signals are demodulated and output to the
Topcon receiver.
The modem requires a regulated DC voltage power supply from +6 to +14VDC with a maximum
current draw of 1.1A at 6VDC.
The incoming data could be also sent over the cellular network using built-in GSM/GPRS (or CDMA,
3G) module if such operation mode is selected.
The radio settings can be done through the built-in Command Line interface (CLI), or through the
configuration and maintenance application software running on the PC – “TRU”.
Note: The cell module option is currently not available. References to the cell module option in this
manual are for future configurations that have not been released.

GMSK – Minimal Shift Keying with Gaussian Filtering 4.8 kbps 9.6 kbps 4.8 kbps 9.6 kbps
4FSK – Four Level Frequency Shift Keying 9.6 kbps 19.2 kbps 9.6 kbps 19.2 kbps
Physical Interfaces
P/N 7010-xxxx 1-3
Link Status Indicators
External LED’s are used for Link and Line status indication:
Power Interface
The power interface allows connection to an unregulated DC power source. The DC power source
(third party or user supplied) must provide peak 7.0 Watts of DC power between 6 and 14VDC. The
power interface is protected against reverse polarity connection, as well as protected against high-
voltage transients.
RF Interface
The RF interface is a 50-ohm impedance matched standard MMCX connector as required by
regulation. Switching from UHF to GSM/GPRS (or CDMA) operation mode and vice versa is
provided on RF interface.
Bluetooth Interface
Bluetooth antenna connector of Radial UMP series (R107003010) is used for Bluetooth antenna
attachment.
LED Name Color Description
TXA Green Active if modem transmits Data over radio link (min.
light on 200ms)
RXA Red Active if modem receives Data over radio link (min.
light on 200ms)
BLUETOOTH Blue Active if modem receives or transmits Data over
Bluetooth interface
WARNING
Before transmitting, always confirm that the antenna is connected.
Never transmit without the antenna or load connected.
WARNING
Mismatching of impedance between the DUHF II, antenna, and cable will cause a lesser transmit
power and result in a higher VSWR.

Hardware Architecture
Functional Requirements
The UHF Modem/Cell/BT Board consists of the following main sections:
• UHF modem Tx/Rx modem;
• GSM/GPRS, 3G, or CDMA modules;
• Bluetooth module.
The block diagram of the DUHFII is presented below. In the figure, consider GSM modem as referring
to either GSM/GPRS or CDMA modules.
Electromagnetic Compliance
This device complies with part 15 of the FCC Rules. Operation is subject to the condition that this
device does not cause harmful interference.
NOTICE
The GSM/GPRS (or CDMA) module installation is optional. The mechanical design and software tools
provide easy way for GSM/GPRS module optional installation and configuration.
Electromagnetic Compatibility
P/N 7010-xxxx 1-5
Changes or modifications not expressly approved by the manufacturer could void the user’s authority
to operate the equipment.
Installation of Digital UHF II module into device shall comply with section 2.1091 of the FCC Rules.
If not possible to ensure that the separation between the user and the UHF antenna is greater than 30
cm, the user manual shall contain a statement warning the user to stay away from the UHF antenna by
30 cm at least when the UHF radio is operating in transmit mode.
UHF and Bluetooth antennas shall be shielded from the Digital UHF II module by the construction of
the device, so that not to cause harmful interference to the module.
Electromagnetic Compatibility
Shielding Considerations
The DUHF II transceiver is designed to operate in proximity to noise generating circuitry. However,
certain radiated or conducted frequencies may degrade the performance of the DUHF II 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 DUHF II transceiver.
Frequency Planning
Radiated and conducted signals to and from the DUHF II 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.
It is recommended 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.
WARNING
The DUHF II is classified as an intentional radiator of type radio transceiver. Conducted and
radiated emissions of the standard DUHF II transceiver do not exceed the requirements of FCC
part 90. OEM is responsible for full compliance of final product.
WARNING
Frequencies ranging from 403 to 413 MHz may adversely affect GPS L2.
Do not use these frequencies with a Topcon GNSS receiver.
Introduction
Digital UHF II EXTERNAL DESIGN SPECIFICATION

Mechanical Considerations
EMI interferers
The DUHF II transceiver is easily mounted inside new and existing products. The DUHF II 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.
Shock and Vibration
Sensitive radio transceivers, such as the DUHF II 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.
Thermal Transfer
The DUHF II transceiver requires additional thermal heat dissipation in order to supply maximum
power out at elevated ambient temperatures and high duty cycles. The DUHF II transceiver has a
thermal sensor and a firmware controlled limit switch. The DUHF II will shut down when the PCB
temperature reaches 100°C to prevent permanent damage to transmitter. The DUHF II will produce
approximately 6 Watts of heat at full RF power out.
Materials
The DUHF II transceiver is housed in a metal shield that is a conductor and is electrically connected to
the ground and signal ground pins.
WARNING
It is not recommend the bundling of the antenna interface cable with other signal cables internal
to your product.

Icons
This reference includes icons that appear in the left margin and are designed to help you clearly
identify operating mode in which you can apply a particular command. The following icons are used
throughout this reference:
Operating Modes
The DUHFII modem can be operated in ether of the following modes:
• Factory – This mode is intended for the factory floor only. In this mode, factory personnel can
calibrate the modem and upload the factory firmware image and bootloader to it. The modem
enters Factory mode initially and brings out of this mode after a normal country configuration file
is uploaded.
• Dealer – This mode is intended for the dealers. In this mode, a dealer can load a dealer
configuration file to the modem. This file contains a customized set of parameters that the dealer
have selected to run on the modem. For details about the parameters available in this file, see
“Configuration Files” on page 2-3. The modem enters Dealer mode after a country configuration
file and brings out of this mode after a normal dealer configuration file is uploaded. Once the
modem brings out of Dealer mode, it automatically goes into User mode.
• User – This mode is intended for the end-users. In this mode, a user can apply the parameters
available in the dealer configuration file to the modem. For details about the parameters available
in the dealer configuration file, see “Configuration Files” on page 2-3. Note that every DUHFII
modem shipped to an end-user must be in User mode.

Firmware Images
P/N 7010-xxxx 2-3
Firmware Images
The DUHFII modem stores two firmware images; a factory and a user image.
• The factory image is the factory-installed firmware that is permanently available on the DUHFII
modem.
• The user image is the user-installed firmware that normally controls all modem operations,
including its normal boot process. If the modem boot process with the user image fails for any
reason, the modem can be booted with the factory image.
Initially, the modem is initialized with factory and user firmware images which are identical.
Configuration Files
The DUHFII modem stores three configuration files, specifically: factory configuration file, dealer
configuration file, and country configuration file.
Factory configuration file
This file stores modem calibration parameters and is generated only by the test bench on the factory
floor.
Dealer configuration file
The dealer configuration file limits the selection of frequencies, channel spacings and maximum
output power for an end user. Note that the allowed frequencies are defined by a list of specified
frequencies, not by the range.
typedef struct
