Introduction

This product manual is only addressed to qualified personnel who are well skilled inelectronical/electrical installation and not to the private consumers/end users. The installation,
implementing or setting into operation of the product can be performed only by qualified
personnel.
The product status described in this document may have changed since first publication andtherefore the information in this document about the product status may be outdated. The latest
product information is available on the FOX Series Product page of the Lantronix website.
The engineering of the FOX3-2G/3G/4G products is built on the same technology combining bothversions of the FOX-IN/EN devices with additional hardware extensions and mobile
communications technology into one product. The main characteristic of these products is the
on-board auto-switch that it supports connection to both internal and external antennas byautomatically switching to the external antennas when connected. These AVL products are thefirst design to feature a hardware implementation of this technology.

1.1

General

Security

IMPORTANT FOR THE EFFICIENT AND SAFE OPERATION OF YOUR GSM-MODEM, READ THISINFORMATION BEFORE USE!
Your cellular engines FOX3-2G/3G/4G are one of the most exciting and innovative electronic
products ever developed. With them, you can stay in contact with your office, your home,emergency services and others, wherever service is provided.
This chapter contains important information for the safe and reliable use of the FOX3-2G/3G/4G
devices. Please read this chapter carefully before starting to use the cellular engines FOX32G/3G/4G.

3.1

General information

Your FOX3-2G/3G/4G devices utilize the GSM/GNSS standard for cellular technology. GSM is anewer radio frequency (RF “) technology than the current FM technology that has been used forradio communications for decades. The GSM standard has been established for use in theEuropean community and elsewhere. Your FOX3-2G/3G/4G are a low power radio transmitter andreceiver. They send out and receives radio frequency energy. When you use your modem, thecellular system handling your calls, controls both the radio frequency and the power level of yourcellular modem.
SIM cards are needed for the use of the acquired devices, which are not included in the scope ofdelivery of the device. The SIM cards can be acquired e.g., by specific providers. Additional costs
can result from the use of the SIM cards which are to be borne by the purchaser (client) of thedevices. The seller does not cover the extra costs for the use of the devices. The seller gives norecommendation for the use of specific SIM cards and is not liable for the fact that the devices
are usable with all available SIM cards. The seller is also not liable for any other costs that areneeded for the application of the customer in connection with this device.

3.2

Exposure to RF energy

There has been some public concern about possible health effects of using GSM modems.
Although research on health effects from RF energy has focused for many years on the current RF
technology, scientists have begun research regarding newer radio technologies, such as GSM.
After existing research had been reviewed, and after compliance to all applicable safety
standards had been tested, it has been concluded that the product is fit for use.
If you are concerned about exposure to RF energy, there are things you can do to minimize
exposure. Obviously, limiting the duration of your calls will reduce your exposure to RF energy. In
addition, you can reduce RF exposure by operating your cellular modem efficiently by following
the guidelines below.

3.3

Turn your FOX3-2G/3G/4G OFF before boarding any aircraft. Use them on the ground only withcrew permission. Do not use them in the air.
To prevent possible interference with aircraft systems, Federal Aviation Administration (FAA)
regulations require you to have permission from a crewmember to use your modems while theplane is on the ground. To prevent interference with cellular systems, local RF regulations
prohibit using your modems whilst airborne.

3.8

Children

Do not allow children to play with your FOX3-2G/3G/4G devices. It is not a toy. Children could
hurt themselves or others (by poking themselves or others in the eye with the antenna, forexample). Children could damage the modems or make calls that increase your modem bills.

3.9

Blasting areas

To avoid interfering with blasting operations, turn your device OFF when in a “blasting area” or inareas posted: “turn off two-way radio “. Construction crew often uses remote control RF devices
to set off explosives.

3.10 Potentially explosive atmospheres
Turn your FOX3-2G/3G/4G devices OFF when in any area with a potentially explosive
atmosphere. It is rare, but your modems or their accessories could generate sparks. Sparks insuch areas could cause an explosion or fire resulting in bodily injury or even death. Areas with apotentially explosive atmosphere are often, but not always, clearly marked. They include fuelingareas such as petrol stations; below decks on boats; fuel or chemical transfer or storage facilities;
and areas where the air contains chemicals or particles, such as grain, dust, or metal powders. Do
not transport or store flammable gas, liquid, or explosives, in the compartment of your vehicle,
which contains your modem or accessories.
Before using your modems in a vehicle powered by liquefied petroleum gas (such as propane orbutane) ensure that the vehicle complies with the relevant fire and safety regulations of thecountry in which the vehicle is to be used.

• Do not place the battery in direct sunshine or use or store the battery inside cars in hot
weather. Doing so may cause the battery to generate heat, crack, or inflame. Using thebattery in this manner may also result in a loss of performance.
• Do not attach the battery to a power supply plug or directly to a car’s cigarette lighter.
• Do not pierce the battery with nails, strike the battery with a hammer, step on the battery, orotherwise subject it to strong impacts or shocks.
• Do not solder onto the battery contacts.
• Do not allow the battery to get wet.
• Do not disassemble or modify the battery.
• Immediately discontinue use of the battery if, while using, charging, or storing the battery, thebattery emits an unusual smell, feels hot, or appears abnormal in any other way.
• Do not place the batteries in microwave ovens, high-pressure containers, or on induction
cookware.
• In case the battery drips and the fluid get into one’s eye, do not rub the eye. Rinse well withwater and immediately look for medical care. If left untreated the battery fluid could cause
damage to the eye.

3.11.1

Safety precautions while charging the battery

Be sure to follow the rules listed below while charging the battery. Failure to do so may cause thebattery to become hot, rupture, or ignite and cause serious injury.
• When charging the battery ensure that the battery charging conditions specified are met.
The temperature range over which the battery can be charged is 0°C to 40°C. Charging isinterrupted, if the ambient temperature is outside of this range.

3.11.2

Safety precautions while discharging Li-Ion battery

6.1

Power supply

The power supply for the FOX3-2G/3G/4G devices must be a single voltage source of V+IN = +10.8
V... +32.0 V DC. The operating voltage (V+IN) must be applied permanently to the FOX3-2G/3G/4G
devices and able to provide sufficient current of up to 1.5 A (pulse).
The operating voltage (V+IN and GND) is protected against voltage spikes and reverse polarity, but
NOT protected against continuous overvoltage.
NOTE: Operating voltage range must never be exceeded; care must be taken to fulfill min/max
voltage requirements.

6.1.1

Power supply pins (1 and 2) on the 8-pin connector

One +IN pin on the main 8-pin port is dedicated to connecting the supply voltage, and the GND
pin for grounding.
Both +IN and GND pins serve for charging the connected backup battery (option) and for
powering the FOX3-2G/3G/4G devices. FOX3-2G/3G/4G have an automatic power ON-function
when external power is applied, and no battery connected. The power supply for the FOX32G/3G/4G ranges from V+IN=+10.8 V... +32.0 VDC allowing direct connection to vehicle powersystem.

Automatic shutdown takes effect if:• Under voltage is detected (internal battery level runs below the nominal voltage and theexternal power supply is disconnected).

6.1.3

Power saving

SLEEP mode reduces the functionality of the modules of the FOX3-2G/3G/4G devices to aminimum and, thus, minimizes the current consumption to the lowest level. The FOX3-2G/3G/4G
can be set into the sleep mode using the command $PFAL,Sys.Device.Sleep[ChargeSleep,Doze] with
one or more parameters listed in the table below. Following SLEEP modes are supported by theFOX3-2G/3G/4G devices:

CAN*

Device wakes up when activities on the CAN bus interface are detected. This
wakeup condition is supported only with $PFAL,Sys.Device.Doze.

LowBat=3.6

Device wakes up when the battery voltage drops below the specified value

IMPORTANT: The sleep and wake-up procedures are quite different depending on the selected
sleep mode. Please note that the power saving with "Ring" works properly only when the PIN
authentication has been done and the device is already registered in the GSM network. If you
attempt to activate power saving while the device is not registered in the GSM network, the SIM
card is not inserted or the PIN not correctly entered, the device responds error "ring shutdown
aborted due to bad GSM coverage" and the power saving does not take place.
NOTE: Related to the battery-powered devices only:

When activating any sleep mode, make sure that the internal battery has enough power to safely
wake up the device from that sleep mode. If the internal battery does not have enough power, thedevice can not complete the wake up process.

6.2

Determining the External Equipment Type

Before you connect the serial port pins of the FOX3-2G/3G/4G devices to an external equipment,
you need to determine if the external hardware serial ports are configured as DTE (Data Terminal
Equipment) or DCE (Data Communications Equipment).
FOX3-2G/3G/4G are designed for use as DCE devices. Based on the conventions for DCE-DTE
connections, it communicates with the customer application (DTE) using the following signals:

Special pin description (Pins 4, 5, 6)
The I/O2 and I/O3 (pin 5 and 6) can also operate as CAN-Bus interface if
CAN is activated on the FOX3-2G/3G/4G devices. More details about
the CAN interface can be found in the PDF-files:

AVL-PFAL-CR.pdf
AppNotesForCANBusApplication.pdf
AppNote_CAN_FMS_CAN_OBDII_Howto.pdf.

These pins have dual functions. All are controlled by the internal firmware of FOX3-2G/3G/4G.
Therefore, the user must define whether to use them as analog or digital pins. The configured
digital pins can be inputs or outputs while the analog pins can only be inputs.
Their function is controlled by the command PFAL, IO0[1,2].Config. For example, if you want touse I/O1 as an analog pin, and the I/O2 and I/O3 as digital, use the following commands,
respectively:$PFAL,IO0.Config=AI,2,11// 0 = I/O1; AI = analog; 2 and 11 = min. and max. voltages
for Low and High events$PFAL,IO1.Config=DI,5,10// 1= I/O2; DI = digital input; 5 and 10 = min. and max.
voltages for Low and High events$PFAL,IO2.Config=DI,5,10// 2= I/O3; DI = digital input; 5 and 10 = min. and max.
voltages for Low and High events

If you want to use a digital pin, e.g. I/O2 or I/O3, as a digital output pin, use the following PFAL
commands:$PFAL,IO4.Set=high//4= I/O1; high = sets output to high

$PFAL,IO5.Set=high//5 = I/O2; high = sets output to high

$PFAL,IO6.Set=cyclic,2000,1000//6 = I/O3; cyclic = sets output to high for 2 seconds andlow for 1 seconds.

Some examples how to use them are given in the sections below.
FOX3-2G/3G/4G Series Hardware Manual33

7: Hardware Interfaces
When using an I/O as digital pin you must set it first to high (with PFAL command“$PFAL,IO4.Set=high” or “$PFAL,IO5.Set=high” or “$PFAL,IO6.Set=high”), otherwise 0V will bemeasured (and the device could get damaged).
7.1.2.1

How to use I/O pins (4, 5, 6) as analog inputs

These pins can operate either as digital or analog inputs, however they should be configured andcalibrated with PFAL commands for such purposes.
Analog voltages of up to 32.0V with a 10 bits resolution can be processed and remotely evaluatedby a server application. A pull-up resistor to a constant input voltage allows for resistivetransducers to ground, e.g., fuel sensor or thermistors.
To use these IOs as analog inputs, send the following command to the device.
$PFAL,IO0[1,2].Config=AI,2,11
where 0, 1 and 2 are indices corresponding to IO1 (pin 4), IO2 (pin 5) and IO3 (pin 6),
respectively. While the value 2 and 11 are min. and max. voltages that will be used togenerate Low and High events, respectively. Detailed information can be found in thesoftware manual“AVL-PFAL-CR.pdf“.
Connection example 1 (for I/O1 and I/O2):
An analog input can be connected to a temperature sensor (a NTC resistor for instance). In the
diagram below is used a fixed resistor from the input voltage to the I/O2, and a variable resistor(Negative Temperature Coefficient - whose resistance or capacitance decreases whentemperature increases) to ground. It is possible to set a low temperature alarm and a hightemperature alarm. Passage through these thresholds will trigger an alarm. We recommend using
SMS or TCP as alarm type with GPIOP protocol. The SMS can be received on a mobile phone,modem, or any GSM device when changes are detected. The analog-to-digital converter (ADC)
inside the unit has an input voltage range from 0 to 2.5 V. An application example is shown infigure below:

Figure 8: Connection example 1 when using it as analog input.
Connection example 2 (for I/O1 and I/O2):
An analog input can be connected to a tachometer generator. The maximum output voltage ofthe tachometer should be + 32.0 V (see illustrated example in figure below).

FOX3-2G/3G/4G Series Hardware Manual34

7: Hardware Interfaces
Both circuit examples (the NTC diagram above and the Tachometer below) are only illustrations
to show the aim of these I/Os when using them as analog inputs.

Figure 8.1: Connection example 2 when using it as analog input.
7.1.2.2

How to use I/O pins (4, 5, 6) as digital Inputs

These pins are high active when used as digital inputs, so you can set VIN(LOW) and VIN(HIGH) to any
levels within the range from +0 to +32.0 VDC. The High and Low levels can be set with PFAL
command (e.g.
PFAL, IO0[1,2]. Config=DI,5,10) - where 0, 1 and 2 are indices corresponding to IO1 (pin 4), IO2(pin 5) and IO3 (pin 6) respectively. The values 5 and 10 are min. and max. voltages that will be
used to generate Low and High events respectively. Detailed information about PFAL commands
can be found in software manual “AVL-PFAL-CR.pdf “.
The figure below illustrates how these inputs can be used in practice. When the internal software
detects input changes from High to Low or vice versa, a Falling or Rising edge Event isrespectively generated. Therefore, depending on the alarm type, the FOX3-2G/3G/4G can react
to the input changes and release different alarms such as sending out SMS, email messages, TCP
packets, opening a CSD connection or activating output ports. The alarm type is configuration
dependent.

Figure 9: Connection example when using it as digital input.
A completed circuit example for all inputs is attached in section 9.1.1.
7.1.2.3

How to use I/O pins (4, 5, 6) as digital outputs

FOX3-2G/3G/4G devices support three IOs which can be used either as input or output. These
outputs are open collectors. They can be connected directly via resistors (R) to LEDs, Relays etc.,
FOX3-2G/3G/4G Series Hardware Manual35

7: Hardware Interfaces
which need no more power than 100 mA @ up to + 32.0 V DC. The figures below show theschematic of possible output connections. To activate these outputs, use the command$PFAL,IO4[5,6].Set=high[low,hpulse,lpulse,cyclic] for IO1, IO2 and IO3 respectively or you canconfigure one or more alarms that activate these outputs when specific events occur (e.g.,$PFAL,Cnf.Set,AL0=IO.e8=redge:IO4.Set=cyclic,1000,2000).
To evaluate this alarm, send firstly this alarm configuration to the FOX3-2G/3G/4G devices andthen trigger IGN-pin to High – as result the IO1 goes High for 1 sec and Low for 2 sec. To set IO1
to Low, just execute the command PFAL, IO4.Set=Low. For more details how to activate an
output and how to configure an alarm, refer to the manual “AVL-PFAL-CR.pdf“. Both figures
below show the schematic connections of how to use this output.
NOTE: The power should not be applied directly to an output pin without having e.g., a resistor
between them.

How to use IGN pin (pin 3)

It is strongly recommended to connect this pin to the ignition key to support the IGN-powersaving function when the vehicle is off.
The IGN-pin has two functions:•

It wakes up the system FOX3-2G/3G/4G from the IGN-sleep mode (when sleeping),

FOX3-2G/3G/4G Series Hardware Manual36

7: Hardware Interfaces
and can be used to monitor the vehicle ignition state, to report/store the trip START and
STOP by using the events IO.e8=redge and IO.e8=fedge respectively.
IGN-sleep mode is one of the eight supported energy-saving modes of the device operation inwhich all unnecessary components are shut down. On IGN wake-up signal, the device returns tofull functionality.
Note that, FOX3-2G/3G/4G devices power on automatically when external power is applied, and
IGN pin provides an additional "wake up" function for the IGN-sleep mode when it is requested.
In case of unauthorized vehicle access/start, you are automatically alarmed by SMS or TCP and
the vehicle recovery can be started by knowing its exact location. In such a case, use the IGN
generated event as a condition to start the vehicle tracking.

1-Wire interface description

A 1-Wire bus uses only one wire for signaling and power. One or several 1-Wire devices can beconnected to the bus at the same time. Only one master should be connected to the bus.
Driver identification, temperature and humidity sensors are quite often used on vehicle
applications. Thanks to the integration of 1-wire interface into the FOX3-2G/3G/4G devices, theFOX3-2G/3G/4G Series Hardware Manual38

7: Hardware Interfaces
system integrators for telematics, fleet management and intelligent transportation system can becost-benefit and time efficiently for their work due to the use of extra external devices which are
not integrated in the in-vehicle computers. Using of the 1-Wire interface, you can know which
drivers are in which vehicles and at the same time monitor the temperature and humidity of theirrefrigerated trucks. In this way, shippers can record by their server the transportation and thedelivery state of their temperature-sensitive loads.
How does it work?
A 1-Wire network consists of a master controller which is connected to one or many slave
devices. The 1-Wire interface on FOX3-2G/3G/4G is a master controller. All the actual monitoring
devices (lightning detector, moisture meter, motion detector, barometer, etc.) are slave devices.
FOX3-2G/3G/4G communicate with temperature and iButton devices via 1-Wire protocol
developed by Dallas Semiconductor, sending and receiving signals over a single data line plus
ground reference. The 1-Wire protocol synchronizes the monitoring devices to the FOX32G/3G/4G. FOX3-2G/3G/4G initiate and requests all activities on the 1-Wire network. One key
feature of the Dallas system is that every 1-Wire slave device has a guaranteed unique address
saved on-chip ROM (Read Only Memory). This enables the master to recognize individually eachof your slave devices and means you can have multiple devices of the same type on the same
network without conflict.

Figure 13: Typical application connection
Setting up a 1-Wire network with the FOX3-2G/3G/4G devices is quite easy. 1-Wire is a simple
system of devices such as temperature, iButton devices etc. that are connected through the 1Wire data line plus ground reference to the FOX3-2G/3G/4G devices. Remember that you can use
and connect to the FOX3-2G/3G/4G 1-Wire line only sensors that require power supply anywhere
between 2.9V and 5.0V. FOX3-2G/3G/4G devices receive on demand the unique address of thetemperature and iButton IDs and other information they deliver. This information can then be
sent via alarms to the remote TCP server.

Mounting

FOX3-2G/3G/4G offer different mounting possibilities, depending on the kind of the antennaused.
1. When installing one of FOX3-2G/3G/4G with internal antennas, please make sure theFOX3-2G/3G/4G' back side with the text "THIS SIDE TO SKY" is facing up to the sky, withno metal objects above or under the device case that can interfere with GPS reception.
2. When installing a FOX3-2G/3G/4G with external antennas, there are two connectors on
the device for connecting a GPS/GNSS antenna such as ANT-12. During the installation,please make sure the receiving side of the GSM/GPS antenna is up, with no metal object
above or under the antenna and device that interfere with GPS reception.
Each of FOX3-2G/3G/4G provide 8 holes to be attached to suitable locations (see figure below). It
can be mounted in different directions and different locations such as on wall or in vehicle.
Fasteners can be Hexagon head with collar self-drilling screws DIN 7504 K, ST3.5 x 32(12) mm anddifferent length. There are no screws included in the delivery pack. More detailed information
how to install the device in the vehicle, refer to the application note
"AppNotes_AVL_Installation_Guide.pdf".
FOX3-2G/3G/4G are NOT waterproof or sealed devices. Care must be taken to ensure the devices
are kept away from water or any other liquids.

External Antenna Ports

FOX3-2G/3G/4G are fitted with two male SMB FAKRA connectors that accept a wide variety of
GSM/GNSS antenna styles for using external antennas instead of the internal ones. The dark red
connector (see figure below) is for connecting a GSM antenna. The blue connector (see figure
below) is for connecting a GNSS antenna. There is no antenna included in the standard delivery, itneeds to be ordered separately.

FOX3-2G/3G/4G Series Hardware Manual49

7: Hardware Interfaces
We provide two combined GSM/GNSS antenna for the FOX3 series. 60140 is a 2G/3G/GNSS
antenna and 60168 is a2G/3G/4G/GNSS antenna.
For more details about 60140 and 60168 antennas, refer to the data sheet available on our web
page.

Figure 26:

GSM/GPS antenna ports

CAUTION: Be careful not to accidentally swap the GSM and GPS connectors. The device will
not function if the antennas are swapped.
To comply with RF exposure requirements, install the antenna so that a distance minimum of
20 cm can be maintained between the antenna and persons.

To connect the 60140 combined antenna to the FOX3 or FOX3-3G devices: Plug the dark, red-colored connector of the antenna to the dark red colored connectorof the device.
 Plug the blue-colored connector of the antenna to the blue colored connector of thedevice.
To remove the 60140 antenna from the FOX3 or FOX3-3G devices:
Press down the latches on the antenna connectors and then pull the antennas.
Do not mount the antenna visible on the dashboard but mount it in a location underneath thedashboard. Hiding the antenna is key to successful security in the event of theft. FOX3-2G/3G/4G
devices generate events in case of the GNSS antenna is connected, disconnected, or cut off. If an
intruder cuts off the GNSS antenna cable, an event is generated which can be used to trigger
alarm notifications to the user.

Audio Interface

Only FOX3 and FOX3-3G-AU devices have a 2.5 mm audio female 4pin connector for connecting
an external active SPK/MIC device. If you are going to connect a loudspeaker directly to thesedevices, we highly recommended the cable of the loudspeaker or the loudspeaker which isgalvanic isolated from the audio channel of the FOX3/-3G devices. This ensures a properly
operation of the loudspeaker.

The following table lists some typical electret microphone electrical and speaker characteristics
when connecting them directly to the FOX3-2G/3G/4G-AUDIO audio interfaces:
Microphone

The microphone should be a electret condenser microphone @ 2.2 k.

Speaker

The speaker should be a passive headset with 8O ohm or an active speakerwith symmetric balanced input. Asymmetric non balanced input will cause
GSM noise in the speaker.

We provide an adapter cable (called "CA81b") with an integrated transformer that provides a fullgalvanic isolation between the FOX3-2G/3G/4G-AUDIO audio interfaces and your loudspeaker. It
allows connection to any loudspeaker on the market. If you would like to use this audio adapter
cable, then you need to order it using the order designation "CA81b".

Schematics

The figure below illustrates a common schematic of how to install the FOX3-2G/3G/4G devices inthe vehicle. For detailed information, refer to the related documents[AppNotes_AVL_Installation_Guide.pdf].

9.1.1

Installation guidance

When installing the FOX3-2G/3G/4G in a vehicle, you will be able to track and locate the vehicle
all the time and you will be automatically notified when disagreements with your storedconfiguration into the FOX3-2G/3G/4G device are occurred. Depending on the user requirements,
the operator may program the digital outputs to activate something e.g., a relay, buzzer, turn ona lamp, etc. The digital inputs can individually be configured e.g., to detect something when it isopened or closed; changes on digital inputs may trigger an output to activate, for example, arelay or buzzer. The IGN line can be connected to the vehicle ignition key to monitor its ON/OFF
position.
Note: Turn the car ignition off before making any connection. Use a common ground point for
all device ground pins. To avoid ground loops and second grounds, isolate all grounded pins of theFOX3-2G/3G/4G from the vehicle body. Do not connect power from a different system to theFOX3-2G/3G/4G.
The outputs of the FOX3-2G/3G/4G devices must be supplied with the same voltage applied to the(+IN) pin. The operating voltage MUST never exceed its range, due to the device is not protectedagain continuous overvoltage. For security reasons, it is recommended to integrate an external 2A
fuse between the positive wire of the FOX3-2G/3G/4G (+IN) and d.c. - power source.
When using an external antenna, be sure to mount it on the dash or on the windshield of thevehicle with the GPS side facing the sky.
Apply power to the FOX3-2G/3G/4G devices only with external antenna connected (if used) andvehicle ignition off. First, connect the GND pin and finally, apply power to the +IN pin of the FOX32G/3G/4G.

What should be considered when using FOX3-2G/3G/4G device

FOX3-2G/3G/4G are devices controlled by means of the PFAL commands which are developed byus. These PFAL commands can be executed when the operating firmware inside the device isrunning. To create application with the FOX3-2G/3G/4G devices and to obtain maximum benefit
from the FOX3-2G/3G/4G operating firmware, you have to setup a specific configuration andstore it in the device. All PFAL commands can be sent to the FOX3-2G/3G/4G with the help of the
Workbench software, which is free of charge and can be downloaded from our website. All PFAL
commands supported by the FOX3-2G/3G/4G and other AVL devices are listed and described in a
separate manual called “AVL-PFAL-CR.pdf” which is accessible online on our website under the
password-protected area.
