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 con-
nected equipment.
Only qualified personnel, such as electricians mandated by the governing body in the
country of installation, may install lightning protection devices.

Notices
OEM7 Installation and Operation User Manual v1 10
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 60950-
1, 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:
lUL listed, or equivalent, in country of installation (for example, TUV, VDE and so on)
for lightning surge protection
lThe 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 groun-
ded 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).

Figure 1: OEM7 Receiver System
1.2.1 OEM7 Family Card
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 Cir-
cuit). The digital section digitizes and processes the IF signals to obtain a GNSS solution (pos-
ition, 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 (mois-
ture, 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 page20 for details.

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

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.

page183.
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:
l5, 15 and 30 m antenna cable with TNC connectors on both ends (NovAtel part numbers GPS-
C006, 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.
