Ethernet Port
The Ethernet ports are Safety Extra Low Voltage (SELV) circuits only and are suitable for
connection within a building only. Do not connect them to Telephone Network Voltage
(TNV) circuits.
Lightning Protection Installation and Grounding Procedure
What is the hazard?
A lightning strike into the ground causes an increase in the earth's potential which results in a
high voltage potential between the center conductor and shield of the coaxial cable. This high
voltage develops because the voltage surge induced onto the center conductor lags in time
behind the voltage surge induced onto the shield.
Hazard Impact
A lightning strike causes the ground potential in the area to rise to dangerous levels resulting in
harm to personnel or destruction of electronic equipment in an unprotected environment. It also
conducts a portion of the strike energy down the inner conductor of the coaxial cable to the connected equipment.
Only qualified personnel, such as electricians mandated by the governing body in the
country of installation, may install lightning protection devices.
OEM7 Installation and Operation User Manual v1 9
Notices
Actions to Mitigate Lightning Hazards
1.
Do not install antennas or antenna coaxial cables outside the building during a lightning
storm.
2.
It is not possible to avoid over voltages 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.
To ensure compliance with clause 7 "Connection to Cable Distribution Systems" of EN 609501, Safety for Information Technology Equipment, a secondary lightning protection device
must be used for in-building equipment installations with external antennas. The following
device has been approved by NovAtel Inc.:
Polyphaser - Surge Arrestor DGXZ+24NFNF-B
If this device is not chosen as the primary lightning protection device, the device
chosen must meet the following requirements:
l
UL listed, or equivalent, in country of installation (for example, TUV, VDE and so on)
for lightning surge protection
l
The primary device must be capable of limiting an incoming surge to 10 kV
5.
The shield of the coaxial cable entering the building should be connected at a grounding plate
at the building's entrance. The lightning protection devices should have their chassis grounded to the same ground near to the building's entrance.
6.
The primary and secondary lightning protections should be as close to the building's entrance
as possible. Where feasible, mount onto the grounding plate itself (refer to the figure
below).

Chapter 1 Introduction
1.2.1 OEM7 Family Card
Figure 1: OEM7 Receiver System
NovAtel’s OEM7 family cards consist of a Radio Frequency (RF) section and a digital section.
Radio Frequency (RF) Section
The receiver obtains GNSS signals from the antenna. The RF section down converts the incoming
RF signals to Intermediate Frequency (IF) signals which are processed by the digital section.
The RF section also supplies power to the active antenna Low Noise Amplifier (LNA) through the
coaxial cable. The RF section has been designed to reject common sources of interference.
Digital Section
The heart of the digital section is NovAtel’s MINOS7 ASIC (Application Specific Integrated Circuit). The digital section digitizes and processes the IF signals to obtain a GNSS solution (position, velocity and time). It also processes the system I/O, shown in Figure 1: OEM7 Receiver
System above.
1.2.2 Enclosure
An enclosure is necessary to protect the OEM7 family card from environmental extremes (moisture, dust, etc.).
1.2.3 GNSS Antenna
The receiver can supply power for the antenna LNA. If the antenna is not compatible with the
OEM7 power supply (5 VDC), an external LNA supply may be required.
1.2.4 Power Supply
A power supply capable of delivering the minimum receiver operating voltage and power is
required. See Power Supply Requirements for Receiver Cards on page20 for details.

wide-band reference GNSS antennas (refer to our web site: www.novatel.com/antennas for
details of available antennas). All antennas include band pass filtering and an LNA. The GNSS
antenna chosen depends on the particular application. Each model offers exceptional phase
OEM7 Installation and Operation User Manual v1 19
Chapter 2 Installation of OEM7 Family Receiver Cards
center stability and a significant measure of immunity against multipath interference. Each
antenna has an environmentally sealed radome and all meet the European Union’s Restriction of
Hazardous Substances (RoHS) and Waste Electrical and Electronic Equipment (WEEE).
If a non-NovAtel GNSS antenna is chosen, a typical antenna LNA gain between 26 dB to 30 dB is
recommended in a rover station application.
For more information about antenna selection, see Importance of Antenna Selection on
page183.
2.4 Choosing a Coaxial Cable
An appropriate coaxial cable matches the impedances of the antenna and receiver (50 ohms)
and has a line loss not exceeding 10.0 dB. If the limit is exceeded, excessive signal degradation
may occur and the receiver may not meet performance specifications. NovAtel offers several
coaxial cables to meet GNSS antenna interconnection requirements, including:
l
5, 15 and 30 m antenna cable with TNC connectors on both ends (NovAtel part numbers GPSC006, GPS-C016 and GPS-C032)
A conversion is required between the MMCX, MMBX or MCX connector on the OEM7
receiver and the female TNC connector on NovAtel’s GNSS antennas.
NovAtel recommends using high quality coaxial cables because an impedance
mismatch is possible when using lower quality cables and this produces reflections
in the cable that increases signal loss. Although other high quality antenna cables
can be used, the performance specifications of the OEM7 family receivers are
warranted only when used with NovAtel supplied accessories.
2.5 Power Supply Requirements for Receiver Cards
OEM7 receivers require a power supply that provides:
l
+3.3 VDC ±5% with less than 100 mV ripple
If the voltage supplied is below the minimum specification, the receiver suspends
operation.
If the voltage supplied is above the maximum specification, the receiver may be
permanently damaged, voiding the warranty.
OEM7 family cards contain a DC-to-DC converter, tolerant to input noise and ripple.
A tightly regulated input supply is not required, as long as it falls within the given
input range.
Refer to the following for complete power specifications:

necting Data Communications Equipment on page33 for instructions).
2.6.1 Electrostatic Discharge (ESD) Precautions
When the OEM7 family card is removed from the original packing box, keep the box and ESD protection for future storage or shipment. Leave the OEM7 family card in the static shielding bag or
clamshell when not connected in a normal operating environment.
l
Always wear a properly grounded anti-static wrist strap when handling OEM7
cards.
l
Always hold the OEM7 family card by the corners or the RF shield: avoid direct
contact with any of the components.
l
Never let the OEM7 family card come in contact with clothing. The ground
strap cannot dissipate static charges from fabrics.
l
Failure to follow accepted ESD handling practices could cause damage to the
OEM7 family card.
l
The warranty may be void if equipment is damaged by ESD.
For more ESD information, see Electrostatic Discharge (ESD) Practices on page188.
2.7 Mounting the Printed Circuit Board
The OEM7 family receiver cards are OEM products and the printed circuit board is provided
without a housing structure. This allows flexibility in creating a mounting environment to suit particular product and market requirements.
The mounting and enclosure should provide for the following:
OEM7 Installation and Operation User Manual v1 21
Chapter 2 Installation of OEM7 Family Receiver Cards
l
Mounting of external connectors
l
Protection from hostile physical environments (rain, snow, sand, salt, water, extreme temperatures, etc)
The OEM Integrator is responsible for ensuring compliance of the final
product with the regulatory bodies for those intended markets.
l
Protection from ESD (see Electrostatic Discharge (ESD) Practices on page188)
l
Location to securely mount the receiver using screws
2.7.1 Planning the Mount Location
When planning the mount location for the OEM7 receiver, ensure there is enough room for the
card. There is an area around the card, called a keep-out zone, where other components in the
enclosure do not intrude. This keep-out zone is intended to prevent other components in the
enclosure from interfering with, or damaging, the OEM7 receiver. For diagrams of the exact
dimensions and keep-out zones for each OEM7 receiver card, see:
l
OEM719 Mechanical Specifications on page113
l
OEM729 Mechanical Specifications on page133
l
OEM7700 Mechanical Specifications on page153
OEM7 receivers are not directional in nature and can be mounted in any orientation.
2.7.2 Board to Board Spacing
A minimum amount of space is required between the OEM7 receiver and the interface or system
board the receiver connects to. Refer to the following table for the minimum and suggested spacing.

See Table 1: NovAtel Mounting Rails on
page26 for the rails available.
OEM7 Installation and Operation User Manual v1 22
Chapter 2 Installation of OEM7 Family Receiver Cards
The recommended minimum values in the previous table assumes no recesses or
cut-outs in the interface or system board for antenna connection.
A component keep-out area may be needed below the antenna connector on the
mating interface or system board to facilitate minimum or suggested spacing.
Board to board spacing less than the minimum spacing suggested in the table may
be achieved by incorporating recesses or cut-outs in mating interface or system
board.
2.7.3 Mounting Options
OEM7 receivers can be mounted using standoffs, rails or rails and edge clamping.
Figure 5: Mounting with Standoffs
OEM7 Installation and Operation User Manual v1 23
Chapter 2 Installation of OEM7 Family Receiver Cards
Figure 6: Mounting with Rails
Figure 7: Mounting with Rails and Edge Clamps
The mounting holes in the OEM7 receiver cards accept M3 fasteners with a maximum projected
head diameter of 7.5 mm (0.295"). For the exact spacing of the mounting holes, see Figure 39:
OEM719 Dimensions on page113, Figure 46: OEM729 Dimensions on page133 and Figure 49:
OEM7700 Dimensions on page153.
OEM7 Installation and Operation User Manual v1 24
Chapter 2 Installation of OEM7 Family Receiver Cards
For proper grounding and mechanical integrity, mount the OEM719 and OEM7700 with
four screws.
For proper grounding and mechanical integrity, mount the OEM729 with six screws.
When installing cards, ensure all standoffs are properly installed.
Also ensure that the mounting location (whether using standoffs, bosses or rails) is
level.
The amount of board deflection (bow and twist) must not exceed 0.75% of the
receiver card's characteristic dimension. For example, on the OEM7700, which is 71
mm long and 46 mm wide, the deflection along the length must not exceed 0.53 mm
and the deflection along the width must not exceed 0.34 mm.
Care needs to be taken when mating the OEM7700 receiver to an interface card or
system board. The high-density, 60 position connectors on both cards need to be
properly aligned before mating to prevent damage to the connectors. See Figure 8:
Mounting the High-Density, 60 Pin Connector on the next page.
A method to ensure proper alignment of the connectors is to slowly bring the mating
faces together and let the connectors find their centers as the mating faces come to
rest against each other. At this stage, visually check that the connectors are aligned.
If the connectors are aligned, gently push the connectors together to mate them.
A fixture or jig will also be of help in ensuring proper alignment between the two
connectors.
OEM7 Installation and Operation User Manual v1 25
Chapter 2 Installation of OEM7 Family Receiver Cards
Figure 8: Mounting the High-Density, 60 Pin Connector
OEM7 receivers have an area on the edge of the cards to allow the use of mounting rails. This is
the area of bare copper outside of the keep-out zone. On the OEM719 and OEM7700, this area is
1.75 mm wide. On the OEM729, this area is 2.5mm wide. See Figure 45: OEM719 Mounting Sur-
face on page119, Figure 48: OEM729 Mounting Surfaces on page135 and Figure 51: OEM7700
Mounting Surfaces on page155 for the dimensions of this area.
For most non-demanding applications (e.g. base stations, remote sensing, desktop units and IT
infrastructure), standoffs or bosses are sufficient to provide a secure mounting location.
Using rails to mount the OEM7 receiver improves the thermal and vibration performance of the
receiver. Securing the OEM7 receiver to mounting rails using clamping bars provides the most
secure configuration for aggressive thermal and vibration applications. See Table 1: NovAtel
Mounting Rails below for information about the OEM7 mounting rails available from NovAtel.

Ensure the IO connector height and antenna cable/connector height facilitate the desired
board to board spacing and do not violate OEM7 receiver card height keep-out zones.
For more details about mounting OEM7 receiver cards, refer to the OEM7 Receiver Card
Mechanical Integration Application Note (D19021).
2.7.4 Thermal dissipation
To ensure functionality and reliability, the OEM7 receiver cards must operate within the specified ambient air temperature limits (-40°C to +85°C).
The OEM7 receivers have been designed to efficiently transfer heat from the receiver components into the printed circuit board. Mounting the OEM7 receiver on rails, or attaching heat
sinks to the mounting areas, will transfer the heat from the receiver card to adjacent circuit
boards, the enclosure or the air.
The mounting area is the area of bare copper on the sides of the receiver that are outside of the keep-out zone. See Figure 45: OEM719 Mounting Surface on page119, Figure
48: OEM729 Mounting Surfaces on page135 and Figure 51: OEM7700 Mounting Surfaces
on page155.
For more information about thermal dissipation, refer to the OEM7 Receiver Card Mech-
anical Integration Application Note (D19021).
2.7.5 Vibration
OEM7 receivers are rated to 20g RMS (MIL-STD_810G Method 514.6E-1, Category 24). However,
for high vibration installations, special considerations are required.
For OEM719 and OEM7700 receiver cards to meet the 20g vibration rating, the receiver card
must be mounted using rails. OEM729 receivers meet the 20g vibration rating using standoffs,
bosses or rails.
For more information about vibration considerations, refer to the OEM7 Receiver Card
Mechanical Integration Application Note (D19021).
2.8 Preparing the Data, Signal and Power Interface
The interface provides connections to some or all of the following:
l
Communication ports, including COM, Ethernet, USB and CAN
l
Input and output timing strobes
l
Power input
OEM7 Installation and Operation User Manual v1 27
Chapter 2 Installation of OEM7 Family Receiver Cards
l
RF signal input
l
Optional external frequency reference
For all OEM7 family cards, the power, status and data inputs and outputs are accessed from one
connector. The interface therefore, must be designed to mate with this connector.
