3. General information
3.1 Power
Tracker is designed for use in automotive on-board system voltage 12/24V, or from
USB adapter 5V 1A. When powered from on-board network has the ability to control the
discharge of the on-board battery and if necessary go into power saver mode before the
appearance of certain conditions depending on the configuration. Modern circuit solutions
enable the Terminal to work consistently in the range of supply voltage from 5 to 36 volts.
M1 has built-in protection against overvoltage, as well as pulse jamming.
3.2 Configuration
The Tracker has a set of commands to configure settings that control the State and
display information (see annex 1). The work can be carried out via the USB port (configurator
utility), via SMS, the TCP commands from the server monitoring (GPRS), as well as Bluetooth
(using Android-Configurator on the mobile device).
Default access password - 12345. If necessary, you can replace the password. If
you lose your password to regain access to the device is possible by contacting technical
support MIELTA.
3.3 Communication
The Tracker has a USB connector for connecting to a personal computer and is used
to supply, configure and update software. Micro-Fit 3.0 connector is used to connect the
main power supply and peripherals. On the reverse side there is a schematic representation
of the plug-in contacts (Figure 2). Before placing it in your site, you must install a SIM card.
For this purpose it is necessary to unscrew the bottom cover of the Tracker, which is
attached with four screws. To protect against unauthorized access, the case is sealed up by a
sticker.

The analog input is designed for voltage measurement and registration of slowly
changing signals. Measurement of signal level occurs 20 times per second. The data
smoothing algorithm is applied.
When you activate the ignition control function, you can select the signal source is
one of universal ports either power network. In this mode, the Tracker monitors voltage and
modifies the Boolean value of the "IGN" when passing through the established threshold
voltages.
Binary input, designed to work with sensors and signal sources open collector type.
High signal level limited voltage 36 V, low level should be no more than 1 V from GND. The
Tracker has an internal pullup to + 3.3 v.
In some cases, to improve anti-jamming and ensure a minimum load current of
a frequency output of the external appliance, you must be connected pullup
resistors with nominal 4.7-10 kOhm between the signal wire and power plus (no
more than 36 V).
Tracker has two modes of frequency measurement - high and low, two modes of
counting pulses with synchronization on the front and the recession signal, as well as logical
status mode entry (entry by the mass closure gives «1»).
Encoder mode uses two ports simultaneously and can keep counting pulses from 0 to
999999 in two directions (increment, decrement). Used, for example, for compensation of
oscillating movements of flow sensors.
Digital output is built according to the scheme "open collector" and is intended for
control of actuating devices. The following operating modes: manual mode (switch output
status on the team) and identification mode (change status to detect the iButton keys/RFID
cards out of the allowed range).

MIELTA M1

Before activating discrete output mode of universal port Tracker, disconnect
all external circuits connected to this port.
Before connecting the external circuit, make sure that the current universal
port in discrete mode will not exceed the maximum value of 200 mA.
3.6 Digital interfaces
Algorithm of working with digital sensors is built on traditional trackers MIELTA
scheme with virtual slots. In Tracker defined slots for each digital interface (eight for RS485
and eight for 1-Wire), each of which can be configured on any sensor supported by tracker.
The main advantage of this approach is flexibility, ease of configuration and the ability to
simultaneously support various protocols on a single interface. Configuring sensors can be
made during operation, do not interrupt the flow of data and does not require restarting.
Data can be obtained immediately after the correct sensor settings (using Configurator, all
changes can be tracked in real time).
Featured network settings for peripheral devices 1-Wire and RS-485 are given in

5. Functionality
4.1 Communication
Tracker has combined communication module SIM868. On the PCB is installed micro-
SIM card holder with hinged lid, for the installation it is necessary to open the case. Supports
hot swapping the SIM card without shutting down the power supply.
Built-in GSM modem works in the ranges 900/1800 Mhz, supports GPRS class B, multi
slot 12/10. To activate the GPRS access point settings are as follows:
access point name;
login;
password.
If GPRS-session is active, the Tracker starts the process of connecting to the
monitoring server. Simultaneous work with three different servers. To configure the
connection, use the following options:
Server address (possibly set up as an IP address, for example 193.193.165.165,
and the DNS name of the server, for example hosting.wialon.com, the
maximum length of the name is 63 characters for the main server and 47
characters for two additional servers);
the connection port, depending on the Protocol (for example, 21204);
the access password to the server, the maximum length is 15 characters;
communication protocol (Wialon IPS 1.1, 2.0 and Wialon IPS binary protocol
supported).
4.2 Unloading of the track to the server and traffic consumption
After successfully connecting to the servers Tracker starts unloading collected data
track from the built-in "black box". The M1's internal memory store up to 10000 records,
intended to send to each server and for unloading through the configurator. The number of
points to be sent to each server does not depend on the number of configured connections.
The order to unload of the messages and "black box" from newest to oldest. Tracker allows
you to unload up to 10 points in the package, no more than 1 kilobyte. When you add a new
server will be unloaded to 10000 previous entries, so if necessary, clean up the "black box".
The following modes of uploading data:
Quick. This type of unloading is the most uneconomical in terms of traffic,
however, allows you to track the object on the server with the minimum of
delay. If the connection to the server is active, the track point to the server is
unloaded immediately after registering the Tracker.
Batch. This type of discharge is a compromise between the consumption of
bandwidth and delay in unloading the current data on the server. This mode is
specified by setting the maximum allowable delay unloading data. That is, a
package to send to the server is formed or when a maximum delay time of

MIELTA M1
12
departure of the previous package, or if the number of records in the black box
is greater than the maximum possible number of points in the package. In other
words, if the black box is empty, the Tracker is waiting for the timeout to allow
sending the next packet, and if the black box records accumulated, then the
Tracker sends data packets without delays until it unloads all the records from
the black mailbox.
According to the schedule. This mode provides for economical unloading track.
To do this, specify the period during which the discharge is the accumulation of
data. Accumulation mode data connections with approved servers and GPRS-
session inactive. Over time accumulate data Tracker connects to the approved
to operate servers and uploads data. After sending all black box data Tracker
again terminates connections and accumulates data during the period of
discharge. Data accumulation mode remotely Tracker is available only for SMS
commands.
Unloading track modes are on a home network and roaming. Here it is worth noting
that the more track points will be sent in the package, the lower the overhead of packet
headers and less traffic consumption. To send data Tracker uses TCP connections.
When you configure the modes and conditions registration track points should be
borne in mind that the Tracker includes support for permanent connection to servers (keep-
alive) connection was lost on timeout. If the timeout time (3 minutes) you have an active
connection to the server was not sending data packets, then the server is sent to the ping
package. This reduces the costs associated with the disconnects and reconnects to the
server, but still consumes bandwidth.
4.3 Unloading track points to multiple servers
The Tracker has the ability to work with multiple monitoring servers simultaneously.
For each server, you can specify any supported in this version of the Protocol. When
configuring the connection sets connection activity indicates an IP or domain name, port and
Protocol for transferring data. Password authorization on the server and the mode of
unloading points is defined globally for all connections after sending a password to access
tracker from one server appears automatically access from other active servers, so if
necessary after the completion of the the remote works with the Sun Tracker to send click
logout. All posts by user actions are sent simultaneously on all servers that are specified in
the settings of the Tracker. The maximum number of entries does not depend on the
number of configured connections-entry points is executed simultaneously for all
connections and unloading through the configurator. If a server is unavailable, then slowed
down unloading points on the available servers.
4.4 Time synchronization
After power Tracker, you must synchronize the system time with the source of
accurate time. Tracker allows you to synchronize time in two ways: to seek the exact time

MIELTA M1
13
with the base stations of cellular operator or get from GPS/GLONASS satellites. Until the
time Tracker is not synchronized, the registration points of the track is prohibited. Sync on
base stations immediately after power-up lets you ensure that data with connected sensors,
even in the absence of sustained signal reception with GPS/GLONASS satellites. It is worth
noting that not all mobile operators support this feature.
Every day when you change the date system time check is received over time from
navigation satellites. If vehicle is stationary for a long time with poor signal reception from
satellites (garage), then perhaps the clock error accumulation system time on the monitor
server in this case will send a message to "WARN: RTC CLOCK".
4.5 Registration of track points
Register Tracker track points being in one of three modes:
stop;
parking;
movement.
After power and time synchronization Tracker allows the registration points of the
track and goes into "stop" mode. In this mode there are two settings:
Period of registration points. Sets the time interval between registration
points track points.
A time of transition in mode of "parking". Sets the maximum time spent in
"pause" mode, after which the Tracker goes “parking”. The main difference
between these modes is that parked its associated configuration, you can
enable power saving mode, which will be described below.
In the "parking" you can configure the registration period points. When you register
the beginning of movement "stop" mode or "parking" becomes "movement". For flexible
adjustment of registration points during movement, there are two profile settings for low
and high speed. First you need to specify boundary velocity ranges, separating low and high
speed. Such partitioning enables you to, for example, to specify different settings for traffic
in the city and on the highway. For each profile contains the following settings:
Distance. Sets the maximum distance relative to the previous registered point
track.
Angle. Sets the maximum change of direction relative to the previous
registered point track.
It's time. Sets the maximum time between registration points track points.
For the "movement" mode is also implemented registration of track points on
exceeding the maximum permissible speed. To configure logging points to exceed the
stipulated two settings:
Exceeding the speed limit. Sets the maximum permissible speed of an object,
by exceeding which the track point.
The increment speed in excess of. Sets the interval register track points for
speeding.

MIELTA M1
14
There is a possibility of formation of track points to exceed the threshold values for
the custom acceleration in units of G acting on the Tracker. Thus, there is a possibility of
fixing cases sharp acceleration or braking the vehicle. In repose to the Tracker operates free
fall acceleration 1 G.
Additionally there is the possibility to adjust the registration point of the track when
the status of the ignition.
4.6 Filtering spurious emissions GPS coordinates
In order to prevent the registration of coordinates with low accuracy in Tracker "GPS
filter" is implemented. This filter has the following settings::
Maximum HDOP;
The minimum number of satellites.
To filter the "false travel" and "stars" on parking included filters and acceleration
sensor filter by ignition. Filters can be independently enabled and disabled. If both filters are
activated and acceleration sensor registers movement start and ignition while inactive (for
example, during the evacuation of the vehicle), the Tracker will register the track. To control
the ignition can be used one of universal ports mode, either supply voltage Tracker. For each
source there is hysteresis. To filter the "stars" on parking in areas with unstable satellite
signal you should disable transmission of coordinates on parking removal appropriate check
box in the Configurator or using the console command.
4.7 Power-saving modes
In Tracker implemented three energy mode:
Main mode. In this mode, the Tracker logs track points and produces data
submission in accordance with predefined settings.
The power saving mode. Mode is designed to conserve battery power on
parking, excluding the data loss. That is, registration data from sensors and
GPS-receiver does not stop. And turns off to save power GSM-module and is
included once per hour to 15 minutes for unloading of the track. If it is
prohibited to unload in roaming, GPRS session is not activated, but left in an
enabled state module and the Tracker is ready, if necessary, to perform the
incoming SMS commands. To enable and disable features you can configure
"allow power saving mode on parking." If the mode is enabled, the Tracker
navigates to it immediately after switching to "parking".
Sleep mode. Mode is intended for long-term parking. Sleep mode periodically
Tracker keeps track of the value of the supply voltage, the rest of the
functionality is unavailable. For cases the power supply of the Tracker directly
from the battery of the vehicle and, if the assumed long breaks between
journeys, it is recommended that you enable the setting "enable sleep mode
on parking" for operation from external power. Here you can set two

MIELTA M1
15
thresholds: voltage of “sleep mode" and exit voltage of the mode. That is, here
the Tracker also tracks the change in voltage (at the got engine voltage higher
than off).
4.8 How to configure settings for Tracker
Tracker configuration is done using the text console commands. To access the
Tracker you must enter a password. In cases of loss of password, you can enter the master
password. Address in technical support of MIELTA. Master password has a limited validity
period.
Several ways to customize the Tracker:
•TCP commands;
•SMS commands;
•Windows configurator utility by USB;
•Android configurator utility by Bluetooth.
Configuring TCP or SMS comes directly sending the text console commands to the
Tracker. It is possible to send multiple commands in a single message, with commands
written in execution order and are delimited by a semicolon. A full list of commands is given
in annex 1.
Working with Mielta Tracker in console mode begin with user authorization pwd
command. All commands except for pwd and logout last line return OK or ERR. OK indicates
that the command completed successfully, ERR means that an error occurred while
executing the command or command is entered incorrectly. In the Tracker, there are several
users, each of which independently authorization is required: 1. Phone (SMS) 1; 2. Phone 2
(SMS); 3. Phone (SMS) 3; 4. Phone (SMS) 4; 5. USB (command line); 6. Bluetooth; 7. TCP
(server monitoring). Allowed simultaneous work with multiple Tracker users. A list of phone
numbers from which allowed sending commands to the Tracker, you can get phone, allow
new phone number-set phone.
After entering the password, Access opens automatically closes after 30 minutes of
inactivity or the corresponding command.

To work on USB or Bluetooth designed Windows and Android configurator utility.
When working through the Configurator also possible sensor tracking and statuses in real
time. When working with Android-configurator to start searches for available Bluetooth
devices.
Once the desired access point Bluetooth connection PIN code is requested, then the
Configurator prompts you to enter a password to access the device. After entering the
correct password Configurator has access to Tracker.
Tracker in the Windows operating system is defined as a virtual COM port. By clicking
the "device selection" in the Configurator runs the search window, where you can view all
devices found trackers. After selecting one of them and enter a password to access the
connection occurs. To work with Windows-Configurator Additionally implements the
following functions:
•firmware update Tracker from a file;
•unloading of the track records of the black box in a file, it is possible to unload
already sent points;
•import/export of all settings in the file Tracker.
4.9 Bluetooth access point
To configure the access point provides the following options for:
PIN. You need to initialize the connection via Bluetooth.
The name of the access point. Is set to identify the Tracker when you search
for available Bluetooth devices. By default, the name is defined as a numerical
value device IMEI.
Implemented multiple modes of operation:
Disabled. Bluetooth access point is unavailable.
Enabled until you restart. Activates the access point until you restart Tracker.
When power is turned on. The access point is activated every time when you
disconnect and external supply voltage (even if you are reconnecting Tracker
continues to work from the built-in battery). Access point after reconnecting
the power active 15 minutes, and if during that time was not Bluetooth
connection after this time is disabled.
Always on. Bluetooth access point always available.
Speakerphone. Bluetooth is used to connect to the headset for voice
communication (see section 4.10).

MIELTA M1
17
Bluetooth access points work on the Tracker practically does not affect the unloading
track and the rest of the functional GSM-module that allows you to connect your Android
device and use it as a monitor sensors in real time.
4.10 Work with a Bluetooth headset
To receive voice calls, you can connect a wireless headset. To do this, in the
“Communication” menu of the configurator program in the “Bluetooth Settings” block,
select the appropriate mode and click the “Write settings”. To pair with a wireless headset,
click the Configure button, search for available devices, and select the desired device. After
clicking the “Write settings” button, the MAC-address of the selected device will be stored in
the terminal memory. The terminal will automatically connect to the selected device, if
available. An incoming call is answered automatically. If the headset is not used, hands-free
mode should be turned off.
4.11 Digital sensors
On each of the available interfaces (RS-485, 1-Wire) there are eight slots and can be
connected up to 8 digital sensors.
To work with the sensor, you must choose the corresponding slot of the interface,
choose sensor type, specify the required settings (bus address, data type, etc.). One sensor
can be selected within the slots. For example, the fuel level sensor produces 3 parameter
(fuel level, frequency and temperature) by adjusting the three slots on the fuel level sensor
for each data type, we get all three measurement parameters and send them to the server
monitoring.
A packet of data sent to the server is created automatically, depending on the
availability of active slots. On the server slots are denoted as follows: R 4.1, ..., R 4.8 for RS-
485 and OW. 1, ..., OW. 8 for 1-Wire. For example, the first slot RS-485 and 5-th slot 1-Wire
bus on the server is as follows: R 4.1 = 4096, OW. 5 = 123456. For some types of sensors
available possibility to receive 2 parameter with a single slot, in this case, the slots on the
server will have the following designations: R R 4.1.1, 4.1.2, ... R 4.8.1, R 4.8.2.
4.12 Work with the system display Mielta
The Tracker System supports display MIELTA RS-485 bus. The system display is used
to display the overall status Tracker, connection parameters, data from different interfaces,
specially adapted for work on stationary and mobile gas stations. Tracker supports up to 8
displays on bus system, each of which can display different data. The display is connected to
one of the RS-485 port slots with the address, similar the sensors.

MIELTA M1

4.13 Working with FLS Autosensor
When working with FLS Autosensor besides the usual parameters (temperature,
level, frequency) the terminal allows you to request data about the quality of driving. The list
of available parameters is given in the FLS instruction. To work with FLS Autosensor at each
of the terminal slots, it is possible to request one parameter (TEMP / PARAM1) or two
parameters (PARAM2). If the request type is PARAM1, then the terminal forms a request in
accordance with the selected address configured on the slot. If the type is PARAM2, the slot
settings indicate the address of the first parameter that must be requested in the FLS.
Address of the next parameter is generated automatically by incrementing the address of
the first parameter. In this case, two values are sent to the slot (for example, R4.1.1 and
R4.1.2).
4.14 Working with ZET7012 pressure sensor
To work with the sensor, it must be pre-configured using the appropriate program
(ZETLab). To work with the terminal, set the exchange rate to 19200 bps, then connect the
sensor to the terminal. In the settings of the RS485 slot specify the type of sensor and
address. The measurement result is displayed with an accuracy of three decimal places. This
result must match the value on the “Measurements” tab of the ZETLab program.
4.15 Driver identification
In the Tracker the driver identification function on RFID cards or iButton keys. For
this must be configured at least one slot type sensor «IBUTTONS». Configuring identification
is made by set iomode. In the command sets the range of values allowed for identifiers. If
the attached key allowed, there is a change of State of a discrete output.
4.16 Manual control of discrete output
To manually control the State of a discrete output provides command
set iomode <ionum> <mode>, where the mode parameter can have a value:
dout_on - digital output: output open
dout_off - digital output: output is closed
4.17 Discrete input
For the "digital input" universal ports there are five submode:
Frequency meter with an accuracy of 1 Hz for band 1-40000 Hz.
Frequency meter with an accuracy of 0.1 Hz range 0.1-40.0 Hz.
Counter. For this mode, in addition, reset the value.
Encoder. Is intended for rotation sensors
State. In this mode, a monitoring server is sent to the binary status (0 or 1).

4.18 Alarm button
To indicate an emergency alarm button function events. Each universal port can be
used to connect the alarm button. When a button is generated extraordinary record in the
black box. Optionally, you can configure the generation of text message to send to the
server monitoring.
4.19 Odometer
The terminal software has an algorithm for calculating traveled distance based on
the received navigation data. The calculation does not depend on the registration of track
points. The traveled distance is stored in the terminal’s memory with an accuracy of 1 meter,
but it should be borne in mind that the accuracy of distance measurement depends on the
accuracy of determining the coordinates, i.e. ultimately it depends on the HDOP parameter
and the satellite signal quality. In good conditions, the error does not exceed 1%. The error
may increase if the track consists of many turns (excavator, loader). You can send to the
statistics server the absolute value of the traveled distance or relative. When sending a
relative value, the traveled distance since the previous registered track point is saved at each
track point. Absolute value is sent in kilometers, relative - in meters.
4.20 Diagnostics
The terminal has several diagnostics commands that can identify some equipment
malfunctions, such as problems with GPS/GLONASS reception or loss of communication with
the sensor. A complete list of diagnostic commands is given in the table “Diagnostic
commands” of Appendix 1.
5Software update
There are several ways to update Tracker:
1. Update via USB through the Configurator utility.
2. Remote Update: Tracker should send the command "serupdate N" in any way
possible (TCP or SMS from the Configurator). N is the version number of the
firmware on the server. During remote Tracker updates continues to work in
normal mode. Firmware update status can be queried from the website server
monitoring from Configurator or via SMS (see the description of the command
"get statusupdatefw").
In case of damage the firmware Tracker and if you cannot upgrade to the regular
way, disaster recovery mode. To restore, you must close the jumper the two special contact
on board Tracker (see Figure 4), connect the PC USB cable (USB port on the computer must
provide the power), run on your computer utility. This utility writes in Tracker base version

of the software which is able to restore the basic functions of Tracker to install the current
version on the regular way.
After the firmware update is completed, the tracker is restarted, then the current
tracker settings are converted, and in the case of an incompatible format of the old and new
version of the QW recordings, the QW is cleared. If the new firmware version has new
settings, then their value is set to the default values. Implemented the algorithm for
converting settings after upgrading the firmware to an earlier version.
6Installation
1. Installation of the M1 tracker on the vehicle can be done in several ways:
2. 1. Hidden installation. The tracker should be placed horizontally with the logo up.
It is allowed to install under plastic, wooden or glass elements of the body and
interior of the car. The power of the tracker should be carried out through the
interface connector from the vehicle's on-board network.
3. 2. Open installation. The tracker is mounted inside the car interior, horizontally,
with the logo upwards, on the dashboard, or at an angle of up to 90 degrees on
the windshield, with the logo ahead in the direction of travel (Figure 4). The
power of the tracker can be either from an on-board 12/24 V network or via a
USB port from a special adapter, with a USB output of 5V, 1A.
