Compact Flash Memory Card Compatability
The DL-V3 has been tested with the Delkin Devices 64 MB, the SanDisk 1 GB, and a variety of
SanDisk CF cards. While the receiver should work with CF cards from any manufacturer, minor
variations between manufacturers’ products may prevent a specific card from working properly.
However, the card is working if it formats correctly, and is recognized correctly, when removed and
reinserted. Please report any problems with Compact Flash Memory Cards to the NovAtel Customer
Service Department. See Page 9 for contact information.
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
1. Do not install the external antenna lines extra-building during a lightning storm.
2. It is not possible to avoid over voltages caused by lightning, but a 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.

12 DL-V3 Firmware Reference Manual Rev 2
Notice
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.

WEEE Notice
If you purchased your DL-V3 product in Europe, please return it to your dealer or supplier at the end
of its life. The objectives of the European Community's environment policy are, in particular, to
preserve, protect and improve the quality of the environment, protect human health and utilise natural
resources prudently and rationally. Sustainable development advocates the reduction of wasteful
consumption of natural resources and the prevention of pollution. Waste electrical and electronic
equipment (WEEE) is a regulated area. Where the generation of waste cannot be avoided, it should be
reused or recovered for its material or energy. WEEE products may be recognised by their wheeled
bin label. 1
RoHS Notice
The DL-V3 is compliant with the European Union (EU) Restriction of Hazardous Substances (RoHS)
Directive 2002/95/EC.) 1

Notice
DL-V3 Firmware Reference Manual Rev 2 13
CAUTION!
1. This device incorporates circuitry to absorb most static discharges. However, severe static shock
may cause inaccurate operation of the unit. Use anti-static precautions where possible.
2. This device is a precision instrument. Although it is designed for rugged operating conditions, it
performs best when handled with care.
3. When the access door for the Compact Flash Memory Card mass storage card (Compact Flash
Card) is screwed closed, the enclosure is sealed to provide protection against adverse
environmental conditions. To minimize the possibility of damage, always keep this access door
closed except when exchanging Compact Flash (CF) cards. Any attempt to remove this access
door or the end-caps impairs the water-resistant qualities of the enclosure, and voids the warranty.
4. Before ejecting the CF card, stop all logging to the CF card.
5. When a power interruption occurs during a data-logging session, 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. See also the RXSTATUS log on Page 94.
6. The DL-V3 can accept an input supply voltage in the range +9 to +28 V DC. This may not be the
same range as other NovAtel products with which you are familiar. By default, operating the
DL-V3 below +9 V DC causes the unit to suspend operation. An input voltage above +28 V DC
may physically damage the unit. The lower cutoff voltage can be adjusted using the COMVOUT
command on Page 24. A 12 V power source should not be allowed to discharge below 10.5 V.
7. Drawing more than the specified maximum current (4 amps) combined total from COM2 or AUX
will cause an internal fuse to interrupt the current. The receiver automatically resets once the
overload has been removed.

Chapter 1 Introduction
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 maximum of 72 channels. SBAS support is
standard and the DL-V3 adaptability offers multi-system, frequency, and size configurations for any
application requirement. Refer to the GPS+ Reference Manual for an overview of each of the above
signal types, available from our website at http://www.novatel.com/support/docupdates.htm. The DL-
V3’s rear 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 and initially available with GLONASS
measurements. Software upgrades to full code and RTK positioning will be released in the future.
Once you connect the DL-V3 to an antenna and power supply, it begins operating as a fully functional
GNSS system. (Refer to the OEMV Family Installation and Operation User Manual for more
information on this topic). Figure 2 shows the DL-V3 without an antenna or connecting cables.
Figure 2: DL-V3 Receiver
1.1 Models and Features
The DL-V3 is available in several different firmware models whose configurations may include other
additional features. Some possible configurations can be seen in Table 1.

Table 2 lists the models, each capable of multiple positioning modes of operation:
Table 2: GPS Positioning Modes of Operation
1.2 OPERATING 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 101, 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.
