Notice
CE NOTICE
The enclosures carry the CE mark.
WARNING: This is a Class B product. In a domestic environment this product may cause radio
interference in which case the user may be required to take adequate measures.
"Hereby, NovAtel Inc. declares that this DL-V3 is in compliance with the essential requirements and
other relevant provisions of Directive 1999/5/EC."
Lightning Protection Notice
What is the hazard?
A lightning strike into the ground causes an increase in the earth's potential causing a high voltage
potential between the centre conductor and shield of the coax cable. Voltages directly applied onto the
centre conductor "roll off" and arrive after the shield pulse producing a high voltage potential between
the centre conductor and shield of the coax cable.
Hazard Impact
A lightning strike causes the ground potential in the area to rise to dangerous levels resulting in
personnel harm or destruction of electronic equipment in an unprotected environment. It also conducts
a portion of the strike energy down the inner conductor of the coax cable to the connected equipment.
Actions to Mitigate Lightning Hazards
See also Figure 1 on Page 18 while reading these guidelines:
1. Do not install the external anten na lines extra-building during a lightning storm.
2. It is not possible to avoid overvoltages caused by lightning, but a lightning protection device may
be used to shunt a large portion of the transient energy to the building ground reducing the over
voltage condition as quickly as possible.
3. Primary lightning protection must be provided by the operator/customer according to local
building codes as part of the extra-building installation.
4. NovAtel recommends installing a secondary lightning protection device. The coaxial cable
entering the building is connected to protective ground through the primary and secondary
lightning protection.

Foreword
Foreword
Congratulations!
Congratulations on your purchase of the DL-V3, a GNSS receiver with exceptional flexibility.
NovAtel is an industry leader in state-of-the-art GNSS receiver design. We believe that our DL-V3
will meet your high expectations, and are working hard to ensure that future products and
enhancements maintain that level of satisfaction.
This is your primary hardware and software reference.
Scope
This manual provides sufficient detail on the DL-V3 to allow you to effectively integrate and fully

Firmware Reference Manual, the OEMV Installation and Operation User Manual and its DL-V3
Addendum.
After the addition of accessories, an antenna and a power supply, the DL-V3 is ready to go.
The OEMV-3 in the DL-V3 utilizes a comprehensive user-interface command structure, which
requires communications through its communications (COM) ports. This manual describes the DLV3-specific commands and logs, see Commands starting on Page 81 and Logs starting on Page 147.
Other supplementary manuals, available on the accompanying CD and on our website at http://
www.novatel.com/support/docupdates.htm, aid you in using the other commands and logs available in
the OEMV family of receivers. This includes the OEMV-3 card within your DL-V3.
DL Explorer is also described, see Chapter 4 starting on Page 56. Integrated with the Control and
Display Unit (CDU) software, these programs provide graphical user interfaces to the DL-V3 for
logging, planning, transferring data files from the Compact Flash (CF) card to the PC/laptop,
upgrading, and converting data types.
Prerequisites
The installation chapters of this document provide information concerning the installation
requirements and considerations for DL-V3. To run the PC software supplied, your personal computer
must meet or exceed this minimum configuration:
Windows compatible mouse or pointing device and SVGA display
USB requires Windows 2000, or Windows XP

Chapter 1Introduction
The DL-V3 is a high-performance GNSS receiver capable of receiving and tracking different
combinations of GPS L1 C/A, L2C, L2 P(Y) and L5 code and carrier, GLONASS L1 and L2 code and
carrier, and L-Band (CDGPS and OmniSTAR) on a maxim um of 72 channe ls. SBAS support is
standard and the DL-V3 adaptability offers multi-system, frequency, and size configurations for any
application requirement. Refer to the GNSS Reference Book for an overview of each of the above
signal types, available from our website at http://www.novatel.com/support/docupdates.htm
V3’s front panel also features light emitting diodes (LEDs) for on the fly observations.
The DL-V3 is a triple-frequency GNSS receiver with integrated L-band capability but without the
need for a separate board. It is GLONASS-enabled with measurements, full code and RTK
positioning.
Once you connect the DL-V3 to an antenna and power supply, it begins operating as a fully functional
GNSS system. Figure 2 below shows the DL-V3 without an antenna or connecting cables.

1.2OPERATING MODES
The DL-V3 can either be controlled by a host computer or be set up for stand-alone operation.
•Controlled Operation: A host computer can transmit logging parameters, receive collected data,
and turn the DL-V3 on or off. Whenever the DL-V3 is connected to a power source (regardless of
whether the DL-V3 is turned “on” or “off”), it detects if there is a host computer connected to one
of its serial ports. If a host computer is found, and there is serial port activity from a host
computer to the DL-V3, the DL-V3 powers up. If the DL-V3’s predefined POWERUP group, see
also Section 4.2.1, Receiver Groups on Page 57, exists in the DL-V3, the DL-V3 runs the
POWERUP group, otherwise the DL-V3 begins to search for satellites and waits for commands
from the host computer.
Only specific serial ports have wake-up capability on data activity. For example, the USB,
Ethernet or Bluetooth® ports do not.
•Stand-Alone Operation: Once the DL-V3 receives configuration commands from a host
computer, it operates according to these parameters. For example, data collection can be
configured in advance by setting up a group to repeat continually.
Refer also to the OEMV Family Installation and Operation User Manual for information on receiver
communications and operation.

2.1.3Selecting a GNSS Antenna
An active antenna is required because its low-noise amplifier (LNA) boosts the power of the incoming
signal to compensate for the line loss between the antenna and the receiver.
NovAtel offers a variety of single and dual-frequency GNSS antenna models, as indicated in Table 3
on Page 31. All include band-pass filtering and an LNA. The GNSS antenna you choose will depend
on your particular application. Each of these models offer exceptional phase-center stability as well as
a significant measure of immunity against multipath interference. Each one has an environmentallysealed radome. The ANT-532-C, ANT-533, ANT-534-C, ANT-536-C, ANT-537, ANT-538, GPS702L, GPS-701-GG, GPS-702-GG, GPS-701-GGL and GPS-702-GGL are RoHS compliant.

2.1.4Choosing a Coaxial Cable
An appropriate coaxial cable is one that matches the impedance of the antenna and receiver being used
(50 ohms), and whose line loss does not exceed 10.0 dB. If the limit is exceeded, excessive signal
degradation occurs and the receiver may not be able to meet its performance specifications. NovAtel
offers a variety of coaxial cables to meet your GNSS antenna interconnection requirements, including:
•5, 15, or 30 m antenna cables with TNC male connectors on both ends (NovAtel
part numbers C006, C016 and C032 respectively)
Your local NovAtel dealer can advise you about your specific configuration. If your application
requires the use of cable longer than 30 m, refer to the application note RF Equipment Selection and Installation on our website at www.novatel.com
, or you can obtain it directly from NovAtel.
High-quality coaxial cables should be used because a mismatch in impedance, possible with lower
quality cable, produces reflections in the cable that increase signal loss. Though it is possible to use
other high-quality antenna cables, the performance specifications of the OEMV family receivers are
warranted only when used with NovAtel-supplied accessories.
2.1.5Power Supply Requirements
This section contains information on the requirements for the input power to the receiver. See
Appendix A, Technical Specifications starting on Page 72 for more power supply specifi cations.
WARNING: If the voltage supplied is below the minimum specification, the receiver will
suspend operation. If the voltage supplied is above the maximum specification,
the receiver may be permanently damaged, voiding your warranty.
The DL-V3 enclosure is supplied with a 12V power adapter with a built-in 3 A slow-blow fuse for use
with a standard 12 V DC power outlet. You can choose to press the DL-V3 power button or wait for
the power sequence, when it monitors the serial ports, as long as a valid voltage is present at the power
supply input, see DL-V3 Power Down and the Power Button on Page 33.
DL-V3 User Manual Rev 3 31

2.1.6Mounting Bracket
A mounting kit is provided along with the DL-V3 to facilitate mounting the receiver to a surface.
The mounting kits are not designed for use in high-dynamics/vibration environments. Contact
NovAtel if your application needs the DL-V3 to be mounted in this type of environment.
To install the mounting bracket provided with the DL-V3, refer to the instructions provided with the
mounting kit.
2.1.7Mounting the GNSS Antenna
The DL-V3 has been designed to operate with any of the NovAtel single-frequency or dual-frequency
GNSS antenna models. See Section 2.1.3, Selecting a GNSS Antenna on Page 30 for more
information.
When installing the antenna system:
•Choose an antenna location that has a clear view of the sky so that each satellite
above the horizon can be tracked without obstruction. (Refer to the Multipath in the
GNSS Reference Book).
•Mount the antenna on a secure, stable structure capable of safe operation in the
specific environment.
2.1.8Connecting the Antenna to the Receiver
Connect the antenna to the receiver using high-quality coaxial cable, as discussed in Section 2.1.4 on
Page 31.
The DL-V3 provides a TNC female connector, see Figure 3 on Page 26, which can be connected to
the antenna directly with any of NovAtel’s coaxial cables.
2.1.9Applying Power to the Receiver
Connect the power supply to the power port. For the DL-V3 you can choose to press its power button
or wait for the power sequence, see DL-V3 Power Down and the Power Button starting on Page 33.
See also Table 4, Enclosure Power Requirements on Page 32.
32DL-V3 User Manual Rev 3
Page 33
Installation and SetupChapter 2
DL-V3 Power Down and the Power Button
DL-V3 incorporates a power button on its front, see Figure 13 below. Pressing this switch, sends a
signal to the microprocessor to turn on or off the GNSS receiver.
Figure 13: Power Button
The DL-V3 has a low-power mode called power-down mode. To enter this low-power mode, press the
power button for at least three but no more than seven seconds, then release it. This is also the mode
the receiver enters into after applying power. In the power-down mode, all logging is disabled.
While power consumption in power-down (sleep) mode is minimal, less than 10 mA, the DL-V3 is
not completely off. If power conservation is important in your application, disconnect the power
source from the DL-V3 when it is not in use.
Press the power button momentarily to turn the DL-V3 back on. Also, the DL-V3 monitors its COM1
and COM2 serial ports. Power-up is triggered on these ports by a DC level of at least +5 V on either
RX or TX. The receiver does not detect activity on COM3. For example, if a key is pressed on a
handheld data logger that is plugged into COM1 or COM2, the time required to come on is only a few
seconds. However, it may require an additional few minutes to establish an initial time and position.
During power-down and power-up time, the serial ports do not process data. You must wait until the
receiver outputs an RXST ATUSA log with a BOOTOK message before typing any commands. Ensure
that your host application (especially Windows) does not poll these COM ports periodically to cause
an accidental power-up.
The automatic power-down feature is disabled when logging is in progress. However, if the power
button is pressed while the DL-V3 is logging data autonomously, the DL-V3 saves any open data files
and then goes into power-down mode.
An additional function of the power button is that it resets the DL-V3 if it is held depressed for at least
10 seconds. This system reset clears stored logging parameters and reverts to a factory configuration
when the power button is released.
2.1.10Connecting Data Communications Equipment
In order to communicate with the receiver by sending commands and obtaining logs, a connection to
some form of data communications equipment is required. In the case of the DL-V3, your PC/laptop
can also communicate with the receiver using the Bluetooth interface. The default configuration
available is shown in Table 5, below, and its pin-out table is in Appendix A on Page 76.

Chapter 2Installation and Setup
DL-V3 COM3 Configuration
The DL-V3 COM1, COM2 and AUX ports are RS-232-only but its COM3 port has Bluetooth/
Ethernet configuration options.
You can switch between Ethernet and Bluetooth on COM3 using the APPCONTROL command, see
Page 85. In the case of switching to Ethernet, power is automatically applied to it after switching.
Bluetooth, on the other hand, may be in sleep mode. If Bluetooth operation is required, it must be put
into active mode using the COMVOUT command, see Page 87. The Ethernet requires more setup
configuration steps. These involve configuring serial, and network, parameters. See Appendix D
starting on Page 178 for details.
If the receiver is turned off, or power is removed, the Ethernet or Bluetooth mode on COM3 is
returned to whichever mode was applied before power-down when it is powered up again.
2.2Additional Features and Information
This section contains information on the additional features of the DL-V3, which may affect the
overall design of your receiver system.
2.2.1Strobes
A set of inputs and outputs provide status and synchronization signals. These signals are referred to as
strobes. Not all strobe signals are provided on all receivers. However, for those products for which
strobes are available, you may want to design your installation to include support for these signals.
Pin-out information can also be found in Appendix A, DL-V3 Port Pin-Outs on Page 76
2.2.2Universal Serial Bus (USB)
The DL-V3 receiver, along with the accompanying NovAtel USB drivers for Windows 2000 and
Windows XP, provides three virtual serial ports over a single USB 1.1 connection using USB D(+)
and USB D(-) signals, with a dedicated USB port labelled .
The three virtual serial ports, identified as USB1, USB2, and USB3, are available to existing
Windows applications which use COM ports to communicate (for example, HyperTerminal and
CDU). The NovAtel USB drivers assign COM port numbers sequentially following any existing ports
on the PC/laptop. For example, if a PC/laptop has COM1 and COM2 ports, the NovAtel USB drivers
assign COM3 to USB1, COM4 to USB2, and COM5 to USB3.
T ypically, a PC/laptop has several physical USB ports. The assignment of COM port numbers
is tied to a USB port on the PC/laptop. This allows you to switch receivers without Windows
assigning new COM ports. However, if you connect the receiver to a different physical USB
port, Windows detects the receiver's presence on that USB port and assigns three new COM
port numbers.
The NovAtel USB Configuration Utility installed with the NovAtel USB drivers allows you to change
the COM port numbers assigned to the virtual serial ports. The USB drivers, along with installation
34DL-V3 User Manual Rev 3

instructions, are available on the OEMV Family CD by selecting USB Support from the main menu.
You can also check for updates to the drivers or release notes on our website at www.novatel.com
CAUTIONDo not connect USB ports if USB communications is not being used or you may
risk damaging your receiver.

2.2.3Status Indicators
LED indicators on the DL-V3 provide the status of the receiver. They represent these categories:
• Power
• Receiver Status
• COMs (COM1, COM2 and AUX)
• COM3
• Satellite Tracking
• Flash Card Memory
• Positioning Mode
• Occupation Time
Power
The power indicator glows orange when the receiver is powered and then glows green once the
receiver has been turned on. See also DL-V3 Power Down and the Power Button on Page 33.
Status
The status indicator flashes orange when the receiver is first turned on. Under normal operation,
this LED is off. If a status event occurs, the LED flashes orange again. See also to the chapter on
Built-In Status Tests in the OEMV Family Installation and Operation User Manual and the
RXSTATUS log in the OEMV Family Firmware Reference Manual.
Communication Ports (excluding COM3)
The top of the COM1, COM2 and AUX LEDs flash GREEN when transmitting data while the
bottom of them flash AMBER when receiving data.
COM3
The COM3 section of the LED panel on the front of the DL-V3, has two LEDs:
• 1 for Bluetooth Mode
• 1 for Ethernet Mode
Only one mode may be used at a time on COM3. The active mode’s LED flashes blue for Bluetooth
and glows orange for Ethernet. If the receiver is turned off, or power is removed, the Ethernet or
Bluetooth mode on COM3 is returned to whichever mode was applied before power-down when it is
powered up again. See also Appendix D, Ethernet Configuration starting on Page 178.

2.2.4External Oscillator
For certain applications requiring greater precision than what is possible using the on-board 20 MHz,
voltage-controlled, temperature-compensated crystal oscillator (VCTCXO), you may wish to connect
the DL-V3 to an external, high-stability oscillator. The external oscillator can be either 5 MHz or 10
MHz.
Operation consists of connecting a cable from the external oscillator to the DL-V3’s BNC external
oscillator port, labelled EXT OSC on the back of the DL-V3. See Figure 14 below. The receiver does
not have to be powered down during this procedure.
Figure 14: External Oscillator Port
Once the external oscillator has been installed, the EXTERNALCLOCK command (refer to the
OEMV Family Firmware Reference Manual) must be issued to define the clock model (for example,
cesium, rubidium or ovenized crystal). If the input clock rate is 5 MHz, the EXTERNALCLOCK
command must be issued to change the 10 MHz default rate.

Installation and SetupChapter 2
2.2.5Antenna LNA Power
Receiver RF input gain requirements are easily met when using NovAtel antennas and coaxial cables.
NovAtel antennas employ a built-in, low-noise amplifier (LNA), which typically provides 26 dB of
gain to the received satellite signal. The power to the antenna LNA is provided through the center
conductor of the receiver’s RF port. To achieve the required input gain to the receiver, NovAtel
coaxial cables have been designed to exhibit no more than 6 dB loss.
CAUTIONNovAtel guarantees performance specifications only using NovAtel antennas.
2.2.6DL-V3 Removable Compact Flash Memory Card
Data commands and logs can be recorded from the DL-V3 to a removable Compact Flash (CF) card.
The need for a companion handheld data logger is avoided when continuous user interaction is not
required, since the DL-V3 is capable of logging data according to pre-configured parameters without
any user intervention. In applications when continuous user interaction is required, a simple handheld
controller can be used with the DL-V3, as the controller does not require its own data logging
memory. The reduced handheld data logger or controller requirement simplifies your system and
reduce its total cost and power consumption. By default only a log group named default exists. A
powerup group must be created to take advantage of the automatic functionality, refer to Appendix
B, Commands starting on Page 81 for more informat ion.
WARNING: To minimize the possibility of damage, always keep the CF card cover closed and
latched except when exchanging CF cards. Do not change the card while logging is in progress. Data will be lost. It is not necessary to turn the receiver
off before inserting or extracting a CF card if you are not logging data.
An example of a 64 MB CF card is shown in Figure 15 below.
Figure 15: 64 MB Flash Card
When you insert a CF card into the DL-V3, enter a DISK FORMAT command using the Console
window in NovAtel’s Control and Display Unit (CDU) graphical user interface software. Wait a few
minutes and use the DL-V3 power button to turn it off and then on again. When power is returned, the
DL-V3 should be able to recognize and use the CF card. For more information on CDU refer to its online Help file.

Data Logging
See Section 3.4, Using the DL-V3 starting on Page 51 to begin collecting data.
Collected data can either be transmitted to a host computer over a serial port, or stored on the CF card.
If you choose to log data to the CF card, each logging session is stored in a single, unique file. These
files can then be transferred to a host computer, for data analysis or other types of post-processing, by
one of two methods:
·Transfer the data by means of serial communications, for example, DL Explorer in CDU
·Physically remove the CF card from the DL-V3 and insert it into the host computer,
provided that it is also suitably equipped with a CF card port
See also the DL-V3 commands and logs, detailed in this manual.
Access Door
From Figure 16, Compact Flash Card Door (shown with its latch in the open position) on Page 40,
you can see that the CF card access door is closed with a latch (reference 1 in Figure 16). As long as
the latch is secured, it provides a water and dust-resistant seal around the CF card.
To open the CF card access door, turn the latch counter-clockwise, until it releases the door.
Figure 16: Compact Flash Card Door (shown with its latch in the open position)
T o remove the CF card, unlock the access door. When the door is open, you can see an eject button to
the left of the card. You must push this butt on to partially eject the card. Grasp the card and pull it all
the way out.
WARNING: Do not change the card while logging is in progress. Data will be lost. It is not
necessary to turn the receiver off before inserting or extracting a CF card if you
are not logging data. See Step 4, Stop the Data Logging on Page 51.
T o insert the card, ensure that it is correctly aligned before gently sliding it into the slot. When the card
slides all the way in and locks in place, the eject button extends. If you attempt to insert the card
incorrectly, it will not go all the way in, and the eject button will not extend. In this case, do not force
the card! Remove it, orient it properly, and then insert it. After the card is locked in place, close the
cover.

The data logging mechanism is designed to be robust and to endure power interruptions (and similar
disruptive events) with minimum loss of data. In this situation, allow for your data to be possibly
reduced by several seconds up to a maximum of five minutes. When possible, error messages are
generated to identify problems as they arise. Refer also to the RXSTATUS log in the OEMV Family
Firmware Reference Manual.
Card Choice
You have the flexibility of choosing the CF card with the storage capacity that is the most appropriate
for your needs, based on the selected logging rate. This is discussed in greater detail in Section 3.4, Using the DL-V3 starting on Page 51.
Take for example the case where you have to format and use a CF card (the DL-V3 comes with a 64
MB card but up to a 2 GB card is compatible):
At least 1% of free space must be available on the CF card to open a log file. On a 64 MB
disk, there is a 0.64 MB allowance for the file table.
Using CDU to Format the CF Card
1. Establish a physical com munication connection between the DL-V3 and the PC/laptop. Either
connect COM1 on the back of the DL-V3 to a DB-9serial port on the PC/laptop or connect the
USB port on the front of the DL-V3 to a USB port on the PC/laptop.
2. Ensure the CF card is in its DL-V3 slot.
3. Launch CDU and open the DL-V3 configuration, refer to CDU’s on-line Help for details.
4. Select DL Explorer from the Tools menu in CDU. The DL Explorer window opens.
5. Click on the CF Status button in the DL Explorer Window:
6. Click on the Format button to format the CF card for use with the DL-V3. The format sequence
erases all data previously stored on the disk. This operation is not reversible and a warning
message is also shown:
The Format process closes all log files first. If a file transfer is in progress, it is stopped and then
the disk is formatted. The logs being logged to file are still present in the log list. The following
command can be entered in CDU’s Console window to remove them:

Chapter 3Operation
Before operating the receiver for the first time, please ensure that you have followed the installation
instructions in Chapter 2, Installation and Setup starti ng on Page 25. The following instructions are
based on a COM port configuration such as that shown in Figure 17 on Page 48. It is assumed that a
personal computer, or laptop, is used during initial operation and testing for greater ease and
versatility.
3.1Communications with the Receiver
Communication with the receiver typically consists of issuing commands through the communication
ports from an external serial communications device. This could be either a terminal or an IBMcompatible PC/laptop that is directly connected to the receiver serial port using a null-modem cable. If
you are using an RTK radio it connects to the receiver’s COM port by means of the radio serial cable
supplied with the receiver. It is recommended that you become thoroughly familiar with the
commands and logs detailed in the OEMV Firmware Reference Manual to ensure maximum
utilization of the receiver’s capabilities.
3.1.1Serial Port Default Settings
The receiver communicates with your PC/laptop or terminal via a serial port. For communication to
occur, both the receiver and the operator interface have to be configured properly. The receiver’s
COM1, COM2 and COM3 default port settings are as follows:
•9600 bps, no parity, 8 data bits, 1 stop bit, no handshaking, echo off
Changing the default settings requires using the COM command.
The data transfer rate you choose determines how fast information is transmitted. Take for example a
log whose message byte count is 96. The default port settings allows 10 bits/byte (8 data bits + 1 stop
bit + 1 framing bit). It therefore takes 960 bits per message. To get 10 messages per second then
requires 9600 bps. Please also remember that even if you set the bps to 9600 the actual data transfer
rate is lower and depends on the number of satellites being tracked, data filters in use, and idle time. It
is therefore suggested that you leave yourself a margin when choosing a data rate (115200 is
recommended for most applications).
CAUTION: Although the receiver can operate at data transfer rates as low as 300 bps, this is
not desirable. For example, if several data logs are active (that is, a significant
amount of information needs to be transmitted every second) but the bit rate is set
too low, data will overflow the serial port buffers, cause an error condition in the
receiver status and result in lost data.

Page 45
OperationChapter 3
3.1.2Communicating Using a Remote Terminal
One method of communicating with the receiver is through a remote terminal. The receiver has been
pre-wired to allow proper RS-232 interface with your data terminal. To communicate with the
terminal the receiver only requires the RX, TX, and GND lines to be used. Handshaking is not
required, although it can optionally be used. Ensure the terminal’s communications set-up matches the
receiver’s RS-232 protocol. In the case of the DL-V3, Bluetooth and Ethernet are available.
3.1.3Communicating Using a Personal Computer
An IBM-compatible PC/laptop can be set up to emulate a remote terminal as well as provide the
added flexibility of creating multiple-command batch files and data logging storage files. Any
standard communications software package that emulates a terminal can be used to establish
bidirectional communications with the receiver, for example, HyperTerminal or our own graphic user
interface (GUI) program, CDU. All data is sent as raw 8-bit binary or ASCII characters.
3.2Getting Started
Included with your receiver are NovAtel’s CDU and Convert programs. CDU is a windows-based
GUI which allows you to access the receiver's many features without the need for communications
protocol or to write special software. The Convert utility is a windows-based utility that allows you to
convert between file formats, and strips unwanted records for data file compilation. See the DL-V3 quick start guide or installation.
3.2.1Starting the Receiver
The receiver’s software resides in flash memory. When first powered, it undergoes a complete selftest. If an error condition is detected during a self-test, the self-test status word changes. This self-test
status word can be viewed in the header of any data output log. Refer to the chapter on Messages in
the OEMV Firmware Reference Manual for header information. If a persistent error develops, please
contact your local NovAtel dealer first. If the problem is still unresolved, please contact NovAtel
directly through on of the methods listed in the Customer Service section at the beginning of this
manual on Page 20.
3.2.2Communicating with the Receiver Using CDU
Launch the CDU program and select Device | Open from its main menu. The Open Configuration
window appears. The example below shows an Open Configuration window with two possible
configurations already set up. Your configurations may be different or you may have none at all, in
which case, the Open Configuration window is empty.
DL-V3 User Manual Rev 3 45
Page 46
Chapter 3Operation
Refer to CDU’s Help file by selecting th e Help | Contents menu. See also Chapter 4, DL Explorer
starting on Page 56 for details of CDU’s DL Explorer tool. Ensure you can see the Console and ASCII Messages windows by selecting them from the View menu.
When the receiver is first turned on, no data is transmitted from the COM ports except for the port
prompt. The Console window displays a port name:
[COM1] if connected to COM1 port,
[COM2] if connected to COM2 port,
or
[COM3] if connected to COM3 port
Any of the above prompts indicate that the receiver is ready and waiting for command input. The
screen may display other port names for othe r po rt types, for example USB1, USB2, USB3 or AUX.
1. You may also have to wait for output from receiver self tests. For example, on start-up,
the OEMV family receiver is set to log the RXSTATUSEVENTA log ONNEW on all
ports. Refer to the OEMV Family Firmware Reference Manual for more details.
2. If you find that CDU is unable to locate your OEMV family receiver, it may be that you
have previously used the SAVECONFIG command. In this case, try using a different
COM port to communicate to the receiver. Once communication has been established,
issue a FRESET STANDARD command. You should now be able to use your original
communication port again.
3. XCOM1, XCOM2 and XCOM3 virtual ports can be generated by the receiver. However they
are unlikely to appear as a port prompt as you cannot connect to these types of ports using
CDU. Also, they are not available with the COM command but may be used with other
commands, such as INTERFACEMODE and LOG. Refer to the OEMV Firmware Reference Manual for the virtual ports available and details on the above mentioned logs.
46DL-V3 User Manual Rev 3
Page 47
OperationChapter 3
Commands are typed at the interfacing computing device’s keypad or keyboard, and executed after
issuing a carriage return command which is usually the same as pressing the <Enter> key.
An example of a response to an input command is the FIX POSITION command. It can be as:
[COM2] fix position 51.11635 -114.0383 1048.2 [carriage return]
<OK
where
[COM2] is the port prompt, followed by the command you enter from your keypad or keyboard
and [carriage return] indicates that you should press the <Enter> key.
The above example illustrates command input to the base receiver’s COM2 port which sets the
position of the base station receiver for differential operation. Confirmation that the command was
actually accepted is the appearance of <OK.
If a command is entered incorrectly, the receiver responds with:
<I
NVALID MESSAGE ID(or a more detailed message)
WARNING!:Ensure the Control Panel’s Power Settings on your PC/laptop are not set to go
into Hibernate or Standby modes. Data will be lost if one of these modes occurs
during a logging session.
3.3Transmitting and Receiving Corrections
Corrections can be transmitted from a base station to a rover station to improve position accuracy. The
base station is the GNSS receiver which is acting as the stationary reference. It has a known position
and transmits correction messages to the rover station. The rover station is the GNSS receiver which
does not know its exact position and can be sent correction messages from a base station to calculate
differential GNSS positions. An example of a differential setup is given in Figure 17 on Page 48.

System biases can introduce errors, as described in the Modes of Operation chapter in the OEMV Family Installation and Operation User Manual. In most cases you need to provide a data link
between the base station and rover station (two NovAtel receivers) in order to receive corrections.
SBAS and L-band corrections can be accomplished with one receiver and are exceptions to the base/
rover concept. Generally a link capable of data throughput at a rate of 9600 bits per second, and less
than 4.0 s latency, is recommended.
Once your base and rover are set up, you can configure them as shown in the configuration examples
that follow in Sections 3.3.1 - 3.3.2 starting on Page 50.
48DL-V3 User Manual Rev 3
Page 49
OperationChapter 3
3.3.1Base Station Configuration
At the base station, enter the following commands:
interfacemode port rx_type tx_type [responses]
fix position latitude longitude height
log port message [trigger [period]]
RTCAinterfacemode com2 rtca none off
RTCMinterfacemode com2 rtcm none off
RTCMV3interfacemode com2 rtcmv3 none off
CMR+interfacemode com2 cmr none off
CMR interfacemode com2 cmr none off (same as CMR+)
3.3.3Configuration Notes
For compatibility with other GNSS receivers, and to minimize message size, it is recommended that
you use the standard form of RTCA, RTCM, RTCMV3 or CMR corrections as shown in the base and
rover examples above. This requires using the INTERFACEMODE command to dedicate one
direction of a serial port to only that message type. When the INTERFACEMODE command is used
to change the mode from the default, NOVATEL, you can no longer use NovAtel format messages.
If you wish to mix NovAtel format messages and RTCA, RTCM, RTCMV3 or CMR messages on the
same port, you can leave the INTERFACEMODE set to NOVATEL and log out variants of the
standard correction messages with a NovAtel header. ASCII or binary variants can be requested by
simply appending an "A" or "B" to the standard message name. For example on the base station:
Using the receiver in this mode consumes more CPU bandwidth than using the native
differential messages as shown in Section 3.3.1, Base Station Configuration on Page 49.
At the rover station you can leave the INTERFACEMODE default settings (interfacemode com2
novatel novatel). The rover receiver recognizes the default and uses the corrections it receives with a
NovAtel header.
The PSRDIFFSOURCE and RTKSOURCE commands set the station ID values which identify the
base stations from which to accept pseudorange or RTK corrections respectively. They are useful
commands when the rover station is receiving corrections from multiple base stations. Refer to the
GNSS Reference Book for more information on SBAS, available from our website at:
http://www.novatel.com/support/docupdates.htm
All PSRDIFFSOURCE entries fall back to SBAS (even NONE) for backwards compatibility.
50DL-V3 User Manual Rev 3
Page 51
OperationChapter 3
At the base station it is also possible to log out the contents of the standard corrections in a form that is
easier to read or process. These larger variants have the correction fields broken out into standard
types within the log, rather than compressed into bit fields. This can be useful if you wish to modify
the format of the corrections for a non-standard application, or if you wish to look at the corrections
for system debugging purposes. These variants have "DATA" as part of their names (for example,
RTCADATA1, RTCMDATA1, CMRDATAOBS, and more). Refer also to the OEMV Firmware Reference Manual, which describes the various message formats in more detail.
Information on how to send multiple commands and log requests using DOS or Windows, can
be found on our website at http://www.novatel.com/support/knowledgedb.htm.
3.4Using the DL-V3
A group is a set of logs for the receiver. The default software configuration for group information
includes a group named default. A powerup group must be created to take advantage of the automatic
logging functionality.
Upon acquisition of coarse time, if a group named powerup exists, the DL-V3 executes the group
automatically.
The FRESET command allows you to reset the DL-V3 to its factory default settings. SITEDEF logs,
refer to the DL-V3 Firmware Reference Manual, contain site record information. For example:
Consider the case of logging data at a site and appending filename and other information. The
following steps apply to a base or rover site. For the base, you only need to log one file per session.
1. There is no need to continually start and stop logging if you are using post-processing
software, where it is dealt with automatically.
2. Ensure your antenna is in the correct position at the base and rover.

Information is appended to the CF card file.
3.5Enabling SBAS Positioning
All OEMV family receivers are capable of SBAS positioning. This positioning mode is enabled using
the SBASCONTROL command. On a simulator, you may want to leave the testmode parameter off or
specify NONE explicitly. The following commands are typically used to enable WA AS and other
SBAS modes, for example EGNOS, respectively:
SBASCONTROL enable waas
SBASCONTROL enable egnos
Refer to the GNSS Reference Book for more information on SBAS, available from our website at:
L-band equipped receivers allow you to achieve sub-meter accuracy. In order to use this positioning
mode, you must enable L-band tracking to the Canada-Wide Differential Global Positioning System
(CDGPS) or OmniSTAR signal. A subscription to OmniSTAR is required to use the OmniSTAR
service. The CDGPS signal is free and available without subscription. Refer to the GNSS Reference Book for more information on L-band, available from our website at:
http://www.novatel.com/support/docupdates.htm
To obtain an OmniSTAR subscription, contact OmniSTAR at 1-800-338-9178 or 713-785-5850. If
you contact OmniST AR, you will be asked to provide the receiver’s OmniSTAR serial number (which
is different from the NovAtel serial number). To obtain the OmniSTAR serial number, enter the
following command in a terminal window or the Console window in CDU:

log lbandinfo
The log that is generated displays the L-band serial number in the fifth field following the log header.
It is a six digit number in the range 700000 to 799999. This log also provides the status of your
subscription. Refer to the LBANDINFO command for more information .
In order to activate an OmniST AR subscription, the receiver must be powered and tracking a n L-band
satellite. When advised by OmniSTAR of the appropriate satellite frequency and data link rate for
your location, use the ASSIGNLBAND command to configure your receiver. The CDGPS frequencies
can also be used with the ASSIGNLBAND command. Below are examples for using either CDGPS or
OmniSTAR:
Please refer to the LBANDSTAT command in the OEMV Family Firmware Reference Manual for
details.
3.7Pass-Through Logging
The pass-through logging feature enables the GNSS receiver to redirect any ASCII or binary data that
is input at a specified COM port or, if available, USB port to any specified receiver COM or USB port.
This capability, in conjunction with the SEND command, can allow the receiver to perform bidirectional communications with other devices such as a modem, terminal, or another receiver.

3.8T Sync Option
The T Sync Option section of the OEMV Installation and Operatio n User Manual describes the
relationship constraints of the input signal phase when the Time Synchronization Modification (T
Sync Mod) option has been added to an OEMV-3-based product (this includes DL-V3).
When an external oscillator is connected, T Sync pulses are sent through hardware on the receiver
card and cannot be disabled. You must issue a time-synchronization-enabling command (refer to
ADJUST1PPS TIME in the OEMV Family Firmware Reference Manual)for the receiver to track
properly.

<Alt> + <F4> on your keyboard.
4.2Receiver Operations
DL Explorer can communicate with the DL-V3 to establish data collection groups.
The DL-V3 can collect several types of data. A group is a profile that tells the receiver what type of
data to collect, at what rate the data should be collected and where the data should be stored (for
example, to the CF card). Use the POWERUP group for automatic data collection on start-up.
4.2.1Receiver Groups
T o start logging data, you must create a group profile and transfer it to the DL-V3. When configuring
your group profile, you can define the group settings to determine the type of information the DL-V3
collects. These group profiles consist of the log type, the data destination, the trigger, period and a
description for each log within the group.
To edit a group, click on the Edit DL Groups... button:.
The DL Groups dialog appears. An example is shown in Figure 19, DL Groups Dialog on Page 57.
Figure 19: DL Groups Dialog
The DL Groups panel, to the left of the dialog, displays the names of the current groups including

groups you defined, and the preset POWERUP group provided by DL Explorer. The POWERUP
group can be modified from the software, see Section , Preset POWERUP Group , on Page 60.
Edit a group name by clicking on it directly in the left side panel. Add a new group using the
button, remove a group using the button or duplicate a group using the button.
Group names are converted to all uppercase lettering.
The default group name (other than the preset POWERUP group name) is GROUPX where X is the
next possible number to make the name unique in the DL Groups dialog (for example, GROUP1). The
group name can be changed but must be unique. Group names can be up to eight characters long but
the first character of the name cannot be a number.
A receiver group consists of information in five tabs:
• LogsSee the Logs Tab section on Page 58

A log’s trigger and period information is what determines when and how often the DL-V3 receiver
collects that log’s information. For example, if the trigger and period for the compressed range
measurements log (RANGECMP) is set to OnTime 2, the receiver logs compressed range
measurements every two seconds. For 2 Hz (twice per second), use an OnTime 0.5 trigger.
To edit trigger information for a particular log, first select a trigger from the Trigger drop down box.
The Period drop down box appears dim unless OnTime is selected as the trigger. In this case, you can
edit the number of seconds directly or choose a time period from the Period drop down box. Table 10

97, 98, 99, 116, and 117 respectively for further details on these commands.
You may need to edit the following fields from their default values depending on your application:
Minimum SatellitesSelect a number from 1 to 9 for the minimum number of satellites,
where the default is 4.
Elevation MaskChoose an integer value for the elevation mask angle between 0
and 90 degrees, where the default is 0.
Interfaces Tab
The Interfaces tab, in the DL Groups dialog, is shown in Figure 23:
Figure 23: Interfaces Tab
This tab allows you to specify what type of data a particular port on the DL-V3 can transmit and
receive. Click directly in any of the cells and a drop down box of choices is available The receive type
(Receiver) tells the receiver what type of data to accept on the specified port. The transmit type
(Transmitter) tells the receiver what kind of data it can generate. For example, you would set the
receive type on a port to RTCA in order to accept RTCA differential corrections.
The Ports and Interfaces tabs are originally blank when the user creates a group (in case you don’t
want to alter the receiver ports and interface configurations when you start logging a group).
Otherwise the DL-V3 might drop the connection with CDU when the settings are changed.
Click on the Add Defaults button to add the default values for interfaces. To remove the values (for
example, so as not to interfere with CDU), click on the Remove All button.
You can set the base station ID, when it is transmitting corrections, in the DGPS TX ID field. The
following range values should be used when you are entering a base ID:
RTCA ID: any four character string containing only alpha (a through z) or numerical (0 - 9)
characters
DL-V3 User Manual Rev 3 63
Page 64
Chapter 4DL Explorer
0 ≤RTCM ID ≤1023
0 ≤
CMR ID ≤31
The default entry for the DGPS Tx Id field is ANY. The ANY option forces the message to revert to its
default base ID. The ANY defaults are:
RTCM0
RTCAAAAA
CMR0
It is also possible to disable or enable the generation or transmission of command responses for a
particular port. Disabling of responses is important for applications where data is required in a specific
form and the introduction of extra bytes may cause problems, for example RTCA, RTCM or CMR.
Disabling a port prompt is also useful when the port is connected to a modem or other device that
responds with data the receiver does not recognize.
When NONE is chosen, the specified port is disabled from interpreting any input or output data.
Therefore, no commands or differential corrections are decoded by the specified port.
Ports Tab
The last tab in the DL Groups dialog is the Ports tab as seen in Figure 24 on Page 64:
Figure 24: Ports Tab
This tab allows you to specify the setting for each COM port and the AUX port. The defaults for the
POWERUP group are shown in Figure 24, Ports Tab on Page 64. You can also turn on/off ports by
checking (on) or unchecking (off) their check boxes in the Powered column.
The Ports and Interfaces tabs are originally blank when the user creates a group (in case you don’t
want to alter the receiver ports and interface configurations when you start logging a group).
Otherwise the DL-V3 might drop the connection with CDU when the settings are changed.

B.2APPCONTROLCOM3 Bluetooth/Ethernet Switch
Use the appcontrol command to switch between Ethernet and Bluetooth on COM3.
Use the appcontrol option 12 9 command to restore Ethernet settings back to their defaults
IP:192.168.1.223
Mask:255.255.255.0
DHCP: OFF
The APPCONTROL OPTION 12 9 command triggers a receiver RESET and, on startup, restores the
Ethernet defaults.
The APPCONTROL OPTION 12 1 command resets the XPORT-AR Ethernet device. This does not
restore the Ethernet defaults. The Ethernet device settings are persistent until you issue a FRESET or
APPCONTROL OPTION 12 9 command, see above.
When COM3 uses Bluetooth, the baud rate is set to 115200. When COM3 is switched to Ethernet, the
baud rate is still 115200.
1. When the DL-V3 is in Bluetooth range, your computer can recognize it and is able to
access it using this password: 0000 (four zeroes).
2. If the receiver is turned off, or power is removed, the Ethernet or Bluetooth mode on COM3
is returned to whichever mode was applied before power-down when it is powered up again.

B.3COMVOUTControl COM Peripheral Power
The comvout command allows you to control the peripheral power supply on specific COM ports.
It supports COM2, COM3 and AUX. No power is supplied for peripheral ports when the receiver is
turned off. COM3 does not have a power pin and there is no direct access to COM3.
The comvout command enables (on) or disables (off) the supply of power to the specified port. For
COM2, and AUX, power is turned on or off to the power pin associated with each port. The comvout
command specified for COM3 puts the Bluetooth device to sleep (low power mode), or turns off the
Ethernet device completely, when comvout is set to OFF. The Bluetooth device wakes up from sleep
mode when comvout is set to ON.
Peripheral power is disabled in all cases while the receiver is turned off (if COM2 power is enabled,
COM2 power is disabled while the receiver is off, and is enabled again when the receiver is on).
Also, the COM3 peripheral is off when the receiver is off. This applies to Bluetooth and Ethernet.
Refer to the DL-V3 power specifications in Appendix A of the OEMV Installation and Operation User
Manual.

B.4CURRENTFILESpecify File for FILEHDR/FILETRANSER Logs
The currentfile command allows you to specify a file to which subsequent requests for filehdr and
filetransfer logs apply, see Pages 158-160.
Specified without arguments, the currentfile command clears any previously configured currentfile
settings. The currentfile file command:
•Configures the currentfile to file. File is a name of a file on the CF card specified in a base.ext
format, where base is a maximum of 8 characters and the optional ext is a maximum of 3
characters. Subsequent requests for the filehdr log, see Page 158, displays the filehdr log read
from file or for the filetransfer log, see Page 160, transfers file in filetransfer log packets.
•Causes the receiver to transfer the entire file on all subsequent requests for the filetransfer log
when issued with the dump mode specified as all.
•Causes the receiver to transfer only file packet number packet_id on all subsequent requests for
the filetransfer log when issued with the transfer mode specified as {single [packet_id]}.
Packet_id ranges from 0 to SizePackets-1, see the dirent log on Page 154. The first packet is
numbered 0. Packet size is defined in the file log definition.
•Defaults the dump mode to all when issued without specifying the dump mode.

B.9FRESETClear Selected Data from NVM and Reset
The OEMV freset command is extended to include DL-V3 features. An additional target field,
userdata (value = 10), resets only the DL-V3 user data NVM, thereby resetting all parameters
indicated in this document as “Stored in NVM” to factory defaults. Issuing the freset command with
the “target” field set to standard, resets the userdata NVM as well as OEMV parameters as indicated
in the OEMV Family Firmware Reference Manual.
The DL-V3 factory default command list is on Page 96.
If you issue the FRESET command without any parameters, it is the same as issuing a FRESET
STANDARD command.

B.10 GROUPCreate and Manipulate Groups
A group is a set of log specifiers and configuration parameters that are normally used together in a
specific scenario. When a group is executed, information contained in a group is mapped into a series
of receiver commands which has the same effect as entering the commands individually. The group
can then be viewed as a “batch file” for the configuration of a specific set of receiver parameters.
A maximum of nine groups is supported. Upon creation, the group is added to the group table which
is stored in non-volatile memory (NVM – which is preserved through a complete power failure). Any
modifications to the group parameters are also immediately stored in the NVM.
If a group named "POWERUP" is defined, this group's log specification is executed with groupuse start powerup file upon first acquisition of time after a powerup with a power button, or COM activity
on COM1 or COM2, or after powerup with a freset, and excludes any other pending activity.
The group command allows you to create and manipulate groups. Configuration of group parameters
is handled by commands described in GROUP Create and Manipulate Groups on Page 95 to
GROUPLOG Edit Group Logging Specifications on Page 111.
The group add groupname1 command creates a group named groupname1 and adds it to the group
table. A maximum of nine groups is supported; the group add command fails if a group needs to be
added and nine groups already exist (that is, the group table is full).
The group del groupname1 command deletes the group named from the group table (and also from
NVM). This operation is not reversible.
The group clear command deletes all groups from the group table (and also from NVM). This
operation is not reversible.
The group copy groupname1 groupname2 command copies group information from group
groupname1 to group groupname2. If a group named groupname2 already exists, it is overwritten by
groupname1. This operation is not reversible.

B.14 GROUPCOMAssociate Port Configurations with a Group
This command allows you to associate one or more port configurations with a group. It is identical to
the standard OEMV COM command but with these exceptions:
• an additional leading argument is used to specify the associated groupname
• configuration of COM3 and USB ports is not supported for GROUPCOM
1. GROUPCOM is not supported on the DL-V3’s COM3 port because it may cause the COM3
Bluetooth or Ethernet applications to become non-responsive. Both applications are
preconfigured to the fixed baud rate of 1152000.
2. If you add GROUPCOM settings to a parti c ular g roup, they do not take effect until the next
time a GROUPUSE command is run for that group.
If added, each distinct group may have unique settings for GROUPCOM.
3. Use of the GROUPCOM command does not affect the INTERFACEMODE or COMVOUT
settings for a group.
The set command provides the port settings that are configured the next time the named group is
executed.
The clear command removes any port settings for the specified group name and port. No port
configuration is performed for the specified port the next time the group is executed.
The default command removes any port settings for the specified group name and port. No port
configuration is performed for the specified port the next time the group is executed.
