In-Vehicle Installation Guidelines for FOX3-2G/3G/4G and BOLERO40 Series5INTRODUCTION
This document provides all the necessary information to allow your Lantronix products (e.g. FOX3 vehicle
telematics device) to be properly and safely installed. Before beginning the installation of your product, theinstallation technician must read completely these Application notes and the hardware manual of the usedproduct. Important information contained herein is to prevent damages of the used Lantronix product.
This document is applicable only for the following Lantronix devices:•••FOX3-2G/3G/4G series,
BOLERO40 series,
DISCO-B4/GLONASS/B5-MAGNET

This document is only addressed to qualified personnel which are well skilled in electronical/electricalinstallation and not addressed to private consumers/end users. The installation, implementing or setting
into operation of the product can only be performed by these qualified personnel.

1.1

Installation guidelines and importance of connection for all Lantronix
products

Read these precautions carefully before installing one of the AVL devices in a vehicle. Proper installationof the Lantronix products requires the installer to have a good understanding of automotive electronics,
systems and well skilled in electronical/electrical installation. Secure placement or installation is theowner's responsibility. Lantronix shall not be liable for any accident by improper placement or installationof devices.

1.1.1 Importance of connection❖ Before beginning any wiring procedure, be sure you understand the wiring diagram added (see Figure 2)

in this document for your particular model. A summary of hints is also given in this diagram.
❖ Turn car ignition off before making any connection.
❖ Apply power to the Lantronix device only when all connections have been made properly. FIRST complete

all the connections required among the device according to the instructions given in this document andthen FINALLY apply power to the unit by connecting the positive pole (+IN) of the device to a vehicle(+12V or +24V) power source.
❖ Use a common ground point for all ground wires of the device. Improper grounding can create a fault

current.
❖ Prevent second ground connection path between your Lantronix device and vehicle, which may create

ground loops between your unit and vehicle accessories. These ground loops can damage the device (seeFig. 2 in this document).
❖ The ground-mounted antennas or the device case may often create a fault current, if improper groundingis made.
❖ To prevent a second ground path during installing the device, first install the GNSS/GSM antenna, thenconnect the negative pole of the device (GND) to the vehicle's battery (-) negative terminal and, when
you are sure that all other connections are properly made, apply power to the device by connecting thepositive pole of the device (+IN) to vehicle battery (+) positive terminal or any other (+12V or +24V)
power source.

In-Vehicle Installation Guidelines for FOX3-2G/3G/4G and BOLERO40 Series

6❖ Depending on the Lantronix product you are using, be careful to select the proper wire length and colour

codes of cable used for installation. For more detailed information, refer to the hardware manual of theLantronix product you are using.
❖ To eliminate broadcast signals, reduce electromagnetic interference (EMI) and radio-frequency

interference (RFI) we recommend to use ferrite clips which should be installed at the end of the cable
closest to the AVL device (see figure below).

Figure 1: A ferrite clip is placed on the AVL installation cable for reducing electromagnetic interference during the device operation.

❖ All wires of the cable should be firmly secured. Leaving some slack in the wires or bad wire connections

may cause the connections getting loose due to vibration.
❖ The installation cable with fuse should not be under tension. When connecting the installation cable do

not pull on the wire with fuse, you can damage the fuse or lose the connection. We recommend to fix
the fuse case to prevent getting loose due to vibration.
❖ The range of input voltage that may be applied to the Lantronix AVL devices is from +10.8 V ... +32.0 VDC.

Exceeding these ratings could cause damage to the AVL device. To fulfil the range of operating voltage,
Lantronix recommends using the installation cable with the voltage converter called "KNT100V". This
cable can only be used for the vehicles with 24 VDC voltage sources.
❖ All Lantronix AVL devices are not protected internally against over current. Therefore, for safety reasonsand to eliminate over current, all leading lines on an AVL device, such as Continuous plus (clamp 30) or
Ignition (clamp 15), must be externally protected in the following way: nominal protection value in the
direct line maximally 2A (slow-blow-fuse); nominal protection value in the next superordinate circle
maximally 15A. The CE-conformity of the product is given only under adherence to these electricaloperating conditions. The disregard of these electrical operating conditions leads to an offence against
the EN/IEC 60950-1, particularly against the regulations to the reduction of the fire risk.
❖ Improper wiring can damage the device and the vehicle's wiring system.
❖ Your device installation should be checked periodically to maintain proper operation with your vehicle.

1.2

Installation guidelines❖ Do not mount the Lantronix device or the antenna connected to the device near the electronic devices

and control systems such as speakers, fan motors or actuators. In particular, devices with internalantenna react sensitively with interferences on the GPS receiver.
❖ Do not mount the Lantronix device, antenna, or any other item in the deployment path of the airbag

system.
In-Vehicle Installation Guidelines for FOX3-2G/3G/4G and BOLERO40 Series

7❖ Do not cover vehicle instruments and displays with cables connected to the Lantronix device.
❖ Do not mount the external antenna or the Lantronix device with internal antenna on the metal plates asthese may disturb and attenuate the GSM signal.
❖ Do not mount cables, antennas or devices in locations that they may be affected by moving parts (inparticular, pedals with lever, shift linkage, control mechanism for ventilation and actuators, rotatingparts, hand brake lever, steering linkages and so on).
❖ Do not mount the device near the heat exchangers and their channels. These belong to the air

conditioning system and heating. The consequences are often overheating or condensation onelectronics, SIM card etc.
❖ Always ensure that connections are clean, secure and fasten. Never let them loose, convoluted or

unsecured in cavities. These may often get out of place due to the vibrations and touch any moving partsin the vehicle.
❖ Do not bundle or roll up the excess cable. The produced coil is often the reason for induced voltages that

may affect the GNSS and GSM performances as well as the operating voltage of the device.
❖ Do not place battery-powered devices direct in sunlight or air currents of the heating system. Generally,

batteries operate from -20 °C - +60 °C (discharge range) and 0 °C to +45 °C (charge range).
❖ Some vehicles use glass that contains a thin metallic coating for defrosting or to control solar gain; glass-mount antennas may NOT function properly when mounted on this type of glass. However, mostmanufacturers leave free unprocessed places, mostly centrally, for back fitting of GNSS technology.
❖ Glass mounted antennas should not be mounted in places where the vignettes are fixed. These are often

constructed with metallic inside, which also disrupts GNSS and GSM reception.

1.3

Device installation order

Instructions provided in this section describe the hardware installation of an Lantronix AVL device. It is
recommended that you print this list for reference when installing Lantronix devices. To install a Lantronix
AVL device in a vehicle, follow these steps:
1. Before you connect the wires of the installation cable to the fuse box in the vehicle, plug in the 8-Pin
connector into the device
2. Connect the brown wire (which is the GND) to the GND of the vehicle
3. Connect the blue wire (which is the IGN line) to the ignition of the vehicle and other wires like digital
inputs (if needed)
4. Pins that are not planned for usage can be left open without anything connected to them. Table 1, 2 and3 in chapter APPENDIX describe the pin functionality for the installation cable on the Lantronix AVL
devices
5. Finally, connect the red wire (which is the Vin) to the external power supply (positive pole)
6. Now turn ON the ignition of the vehicle to start up the AVL device

INSTALLATION INSTRUCTIONS
1.4

Connection precautions

Selecting an installation location for an external antenna or device is critical:
If your product comes with an external glass-mounted antenna, then install the GNSS antenna in the vehicle
in the locations that are dry and distanced from sources of extreme heat and where the system can receive
GNSS satellite signals from all directions. During installing the antenna, be sure that the cable is extended
and not rolled up. When rolling up the antenna cables, the induced voltage caused by magnetic field may
effect on GSM and GNSS performances and operating voltage as well.
If you use a ground-mounted antenna, please ensure that the antenna ground does NOT come into contact
with vehicle body. This is recommended to avoid the ground loops, which may occur when there is morethan one ground connection path available.
If your product comes with built-in antenna (e.g. BOLERO40) or you want to use the device with internalantennas (e.g. FOX3), then install the device in a suitable location that does not interfere with the GNSS/GSM
reception. Do not mount the antenna or devices with internal antennas on the metal plates as these may
disturb and attenuate the GSM signal. When a location is found, then perform the test given in chapter 3.4.
Identifying suitable power sources for the unit is also critical.
Turn car ignition off before making any connection to the AVL device. Check the polarity of the battery
terminals with a voltmeter before connecting any of the Lantronix products in the vehicle. Later on, you haveto identify an electrical ground in the vehicle and it should be used as a common ground point for all groundwires. Connect the unit ground wire to the identified ground ([-]) negative ground battery terminal or vehicle
chassis, see possibilities for power source connections below) and, only when all other connections are
made, connect the unit power lead (+IN) directly to the vehicle battery (+) positive terminal (12V/24V) by
using a 2A fuse.
Possibilities for power source connections:A) Power is taken directly from the vehicle battery and the vehicle chassis is used as a common ground:
The vehicle chassis (➋) can be used as a common ground ONLY WHEN your vehicle does not have a main
switch (➊) equipped between the battery negative terminal and the vehicle ground. If this switch is in yourvehicle and you select the vehicle chassis as a common ground, then the external power to the unit will
depend on the position of this switch. For non-battery-powered units, the unit is powered OFF, once thisswitch is OFF.
B) Power supply pins are connected directly to the vehicle battery:
The battery negative (-) terminal can be used as a common ground ONLY WHEN no second ground occurs.
When an electronic accessory in-vehicle (e.g. radio, cool box and so on) uses the body of the vehicle forground, and the device ground pin is directly connected to the battery negative (-) terminal, this can form acommon return path if the antenna (➌) or device case comes into contact with vehicle body (Figure below
illustrates such ground-loops). In such cases, some vehicle accessories can limit the amount of ground that
other accessories can receive. This is commonly known as a ground loop. In other words, a ground loop is an
unwanted electric current path in a circuit resulting in interference, when two grounded points in the same
circuit have different potentials. To prevent such ground loops, it is recommended to shield your device andthe antenna so that no second ground occurs. Additionally, the device positive lead (+IN pin) must be
protected by using a 2A fuse. Most vehicle manufacturers recommend that when both leads (positive and

In-Vehicle Installation Guidelines for FOX3-2G/3G/4G and BOLERO40 Series

9negative) go directly to the battery, they need to be fused (refer to the manufacturer’s installation guidelines
manual for the vehicle).

Figure 2: Power supply pins are connected directly to the vehicle battery. The unit case, antenna and cables are electricallyshielded to avoid ground loops (in the diagram are shown in the green color).

The latest vehicles are equipped with a shunt circuit protection between vehicle battery and vehicle fuse box
allowing the measurement of sink current values flowing through it. Normally, when the vehicle ignition isturned off, just a small current is drawn from the battery - less than 50 mA. That means, if the power pin(+IN) is connected behind the shunt circuit, the installed Lantronix device will not be able to draw current
from the vehicle battery while the vehicle is off, as the shunt limits the current flowing through it. Therefore,
it is recommended to install one of Lantronix devices in front of the shunt, as shown in the Fig.2 above.
According to your application requirements, several power sources may be required:❖ The input supply voltage must provide continuous 12V/24V power and must be able to supply sufficientcurrent even when the vehicle is off.
❖ Voltage on the ignition pin should be 12V/24V when the vehicle is on, and 0V when it is off (for ignition

controlled application).
❖ To get input changes events, the voltage on an input pin should be 12V/24V for high and 0 V for low.

Using a voltmeter to test for these conditions will help to ensure a successful installation. During this time,ensure that all vehicle accessories (radio, lights, air conditioning, etc.) are turned off.
If the IGN-pin is not used to control the vehicle ignition states, then it is recommended to connect it to theoperating voltage (+IN) to use the IGN - Sleep mode. With the help of an external switch this will wake up
the device from IGN - Sleep mode (with a HIGH signal on this pin).

In-Vehicle Installation Guidelines for FOX3-2G/3G/4G and BOLERO40 Series

10Additional installation instructions when using features of the built-in 3D acceleration sensor:
To use the features of the built-in 3D acceleration sensor, please ensure:

1. The device should be accurately installed on any flat surface that is parallel to the horizontal axis ofyour vehicle with the 16pin connector (for FOX3) or antenna cables pointing to the driving direction.

2. The device should be secured to the vehicle so that no false events can be occurred.
3. The device should be configured by additional alarms to fully use this feature. The force value thatyou will enter in the configuration should correspond to the value that your application requires.

4. The value in the configuration should be entered without commas or points (e.g. 1500).

Please note that, the pictures below shows that the Z-axis are vertical and pointing up (positive up) and theX- and Y-axes lie on a horizontal plane. The arrows show always positive values.

1.5

Installing DISCO-B4

The DISCO-B4 contained in a PA6 plastic weatherproof enclosure is designed for mounting on an exterior flat
surface of a vehicle such as the roof. After you have inserted the SIM card inside the device and the casing iscompletely water-sealed, then you can install your device on the vehicle's roof or somewhere else on the flat
surfaces. The DISCO-B4 device can be installed in various ways. The following figure gives an example of atypical installation variant. Before you start the installation, ask for professional advice on the mounting thatwould best suit your needs.
To install the DISCO-B4, follow the steps listed below:✓ Place the six rubber feet into the six spacers of the device.
✓ Installing of the DISCO-B4 requires drilling to your vehicle roof in order to bolt them on. To avoid keeping
the device in direct contact to the sunlight that leads to overheating, it is recommended to mount the
DISCO-B4 device behind the air deflector on your truck roof. Therefore, locate the mounting place anddrill a 32 mm (±0.1mm) hole in the vehicle roof. The device should be placed away from other installed
devices that may obstruct the line of sight between the device and the satellites.

✓ First loosen the mounting nut on the device's bottom side and take it out of cable.
✓ Pass the cables through the hole and then place the device on the mounting surface. The rubber feetmust make full contact with the vehicle's metal roof.

✓ Pass the cable in the nut and then tighten the mounting nut until movement is blocked. The maximum
tightening torque used on the mounting nut must not exceed the maximum value of 12 Nm,
recommended 10 Nm.
In-Vehicle Installation Guidelines for FOX3-2G/3G/4G and BOLERO40 Series

11✓ Make sure the top surface of the device is pointing upwards when tightening the mounting nut (seeexample in diagram below).

✓ Finally, connect the vehicle installation cable to the 8pin connector on the external cable of the DISCOB4.

✓ Another mount option is to use 6 x hex cap screws M4x30 or longer (not included) - as shown on theright side of the figure below (second mounting option). For this mount option, refer to the DISCO-B4
Hardware Manual and find out the dimensions of housing.

Figure 5: Mounting the DISCO-B4 on the vehicle's roof

The pin out of the 8pin connector at the end of the cable is given in chapter 4.1.

12ADDITIONAL INSTALLATION HELP
1.6

Selecting a location with good reception for AVL devices

The unit (e.g. FOX3-2G/3G/4G or BOLERO40 series) should be affixed to:✓ a dry solid surface,✓ not exposed to extreme heat,✓ free from extreme vibration.
The antenna should be placed in a location where:✓ valid GNSS fix could be obtained,✓ not covered or blocked by metal,✓ not near electronic management and control systems,✓ all connection points to the vehicle are easily accessible (by the user).
Good mounting locations can often be found:✓ on the windscreen (not for battery-powered devices),✓ under the vehicle’s dashboard,✓ under the seats,✓ on the underside of the rear windshield deck in passenger cars.

1.7

Install Ignition (Optional)

It is recommended to install the IGN line as shown in Fig.2 above. Ignition-controlled power can often be
found in the vehicle’s fuse box or directly from the vehicle’s ignition system. When testing for ignitioncontrolled power, ensure that your power source remains at 12V/24V when the ignition of vehicle is on.
Connect the ignition wire from the unit’s power cable to the ignition-controlled source protected with a 2A
fuse. The ignition input can also be used for journey START and STOP reports (programmable in the software).
The pinout of the vehicle installation cable for FOX3-2G/3G/4G or BLERO40 series is given in chapter Error! R
eference source not found..

1.8

Install additional Inputs/Outputs (Optional)

The inputs provided on the FOX3-2G/3G/4G or BOLERO40 series are high active and will sense a voltagechange between low (ground) and high (12V/24V). This can be done by installing a push button between thedigital input and 12V/24V. Push buttons are open by default, and when the button is pressed the switch
closes to 12V/24V. When the push button is closed (12V/24V) the input changes its state from low to highand the internal software generates the rising edge event. Similarly, when the push button is opened(grounded), the input changes its state and the unit generates the opposite falling edge event. These events
can then be programmed in the internal software to execute different alarms or activate e.g. a siren mounted
in the car via a digital output. The provided outputs can be used to control external devices, usually a relay.
For more details, refer to the hardware manual of your device.

1.9

Perform testing

The test should be performed with vehicle in an open area where GNSS signal is available. When performing
the initial test, follow the steps listed below:


Make sure all electrical connections including grounding are properly done.

Turn the device on and check its behaviors whether there is sufficient GNSS and GSM reception using
Workbench software. You may also configure 4 alarms to show the GNSS and GSM operation via LED
indicators. See examples below.
PFAL,Cnf.Set,AL1=GSM.GPRS.eConnected:IO12.Set=high
ExamplePFAL,Cnf.Set,AL2=GSM.GPRS.eDisconnected:IO12.Set=low
PFAL,Cnf.Set,AL3=GPS.Nav.eFix=valid:IO13.Set=high
PFAL,Cnf.Set,AL4=GPS.Nav.eFix=invalid:IO13.Set=low

If you see that there is sufficient GNSS and GSM reception (note that, acquiring of initial GNSS fix may takemore than 2 minutes), turn on your vehicle and check again if any of vehicle's electronics is causing
interferences to the device. If the device could not obtain a fix within 5-20 minutes, then change themounting location of the device and restart the test.
 If no interferences are detected and the device gets a fix, then perform the same test during driving, tocheck if the GNSS fix stays stable and the device is able to get a valid fix even when the GNSS fix is lost.
 When the mounting location has been determined and the test has been successfully completed, turn off
your device and your vehicle and perform the complete installation by keeping in mind the instructions
given in chapter 1.1.
After the device has been mounted, refer to the Getting Started Guide to perform an end-to-end systemtest.
