Configuration password

Protects the device from unauthorized access while using USB or Bluetooth to make any form of configuration changes.

  • Set password - Set the primary password for the device. Required to access the device every time using the USB or via Bluetooth connection.
  • Recovery password (optional) - in the event that the primary password is forgotten, the recovery password can be used as a backup to unlock the device configuration.













GNSS settings

In GNSS Source settings user can configure which GNSS system(s) to use.

List of configurable GNSS sources:

  • GPS
  • GPS + GLONASS
  • GPS + Galileo
  • GPS + BeiDou
  • GPS + GLONASS + Galileo + BeiDou



Power Saving settings

Puts the device into a power-saving mode, preserving the power consumption from the external source or the internal battery. The device enters this mode after the conditions are met.

Online sleep

  • In Online Sleep mode, the device manages the connection only when records need to be sent. The connection is opened at periodic intervals to send records and closed immediately after, without any timeout.
  • Changing the Permanent Link setting during Online Sleep will wake up the device to apply the new configuration.
  • With Permanent Link enabled, the device maintains a constant connection, sending records immediately as they are generated, rather than waiting for the next scheduled send. After sending connection remains open.

Disabled modules in Online sleep

When device goes into sleep mode, some modules are turned off to consume less power. Listed below are the modules and scenarios that are turned off in common with all modes and those that are disabled specifically for the Online sleep mode:

  • GNSS

Online sleep entry conditions

All entry conditions must be met:

  • Movement is not detected by the configured movement source.
  • Device time must be synchronized. This condition depends on the “Record Settings -> Saving / sending mode parameter.
    • After Position Fix - device time is synchronized with GNSS satellites and GPS fix is obtained.
    • After Time Sync - device time is synchronized over NTP, NITZ, or GNSS satellites.
    • Always - device will enter sleep mode without time synchronization and GPS fix.
  • There are no SMS messages being received.
  • Data sockets are closed (ignored when permanent link is enabled)
  • FOTA WEB connection is not in progress.

Online sleep exit conditions

At least one exit condition must be met:

  • Data sending as per Tracking settings.
  • Periodic wake-up (if enabled).
  • Button is pressed.

Power off sleep

Disabled modules in Power off sleep

When device goes into sleep mode, some modules are turned off to consume less power. Listed below are the modules and scenarios that are turned off in common with all modes and those that are disabled specifically for the Power off sleep mode:

  • Modem
  • GNSS
  • FOTA WEB

Power off entry conditions

All entry conditions must be met:

  • Movement is not detected by the configured movement source.
  • Device time must be synchronized. This condition depends on the “Record Settings -> Saving / sending mode parameter.
    • After Position Fix - device time is synchronized with GNSS satellites and GPS fix is obtained.
    • After Time Sync - device time is synchronized over NTP, NITZ, or GNSS satellites.
    • Always - device will enter sleep mode without time synchronization and GPS fix.
  • There are no SMS messages being received.
  • Data sockets are closed (ignored when permanent link is enabled)
  • FOTA WEB connection is not in progress.
  • TCT is not connected.
  • USB is not connected. This condition does not apply if Power bank mode is enabled.

Power off sleep exit conditions

At least one exit condition must be met:

  • USB is disconnected.
  • Data sending as per Tracking settings.
  • Button is pressed.

Time synchronization settings

Accurate system time is essential for proper event logging, record timestamping, and scheduling. The device supports 2 primary time synchronization sources: GNSS and SNTP. When one source becomes unavailable, the device can fall back to the other to maintain accurate time.

  • NTP Resync - how often a device should resynchronize its time. If the set value is not equal to zero, time resynchronization will occur periodically at time intervals to which this parameter is set.
  • NTP server 1 and NTP Server 2 let the user select which NTP server (s) will be used to re-synchronize time.

Prerequisites

Network Connectivity

  • To use SNTP, the device must connect to the internet

Configuration Access

  • TCT NTP settings (e.g., synchronization interval, NTP server domains) must be accessible for setup or modification.

Parameter Description

GNSS Time Synchronization

  • Trigger Condition: If a valid GNSS fix is available and the difference between the GNSS-provided time and the internal RTC is ≥ 3 seconds for a continuous period of 5 seconds, a time correction occurs.
  • Subsequent Synchronizations: After the first successful sync, the wait time before the device checks for another 3-second difference increases to 5 minutes to prevent excessive corrections.

SNTP Time Synchronization

  • Trigger Condition: If the device lacks a GNSS fix for 60 seconds, it attempts to synchronize time via SNTP'.
  • Resynchronization Interval: Defined by TCT NTP settings (default is 3 hours).
  • NTP Servers: 2 servers can be configured; by default, pool.ntp.org is the primary server and time.google.com is the fallback. If the first server is unreachable, the device automatically attempts the second.

Expected Behavior

GNSS Time Sync Process

  • When GNSS is active, the device continuously compares GNSS time to the internal clock.
  • If the 3-second offset persists for 5 seconds, the clock is updated immediately.
  • After the first correction, the device waits 5 minutes before checking for another large time discrepancy.

SNTP Time Sync Process

  • If no GNSS fix is available for 60 seconds (e.g., poor satellite signal, modem off, etc.), the device initiates an SNTP request.
  • If the primary NTP server is unreachable, it tries the secondary server.
  • The device repeats this SNTP synchronization after the configured interval (default 3 hours).

Fallback Mechanism

  • GNSS is the first choice for time synchronization.
  • When GNSS is not available, SNTP ensures the device clock remains accurate until a valid GNSS fix is restored.

Battery settings

Power Bank Support

Power bank support functionality enhances battery longevity by enabling a wider discharge depth for the internal battery and prioritizing the use of external power, such as a connected power bank, to operate the device. Crucially, the internal battery will be protected from both undercharging and overcharging, ensuring optimal operational health.

Location settings

This feature allows switching between location sources.
Parameter: Location source (param ID = 128).

Values:

GNSS (0) - enables GNSS, disables neighbouring cell tower IOs.

LBS (1) - Powers down GNSS, enables neighbouring cell tower IOs. Note, when Saving / Sending Mode (parameter ID: 107) is set to "After position fix" (SMS/GPRS parameter value = 0), Location Source "LBS" is not available.

Location Based Services (LBS)

The Location Based Services (LBS) feature manages and stores the information about detected network cells. This can be used to determine the approximate location of the device withou relying on GNSS. Activating this scenario disables GNSS.

Cell IOs settings are not user-configurable.

To represent a single cell, a total of 5 IOs are required: LAC, CellId, RSSI, MNC, MCC. A total of 4 neighbouring cells are supported, i.e. 5*4 = 20 IOs in total.

Note that depending on modem and network type, RSSI might not be available and is only roughly calculated.

LED indication

This feature allows disabling or enabling LED indication.



Button settings

Multi action button functionality utilizes tracker button for various actions (e.g. Alarm). Button employs click pattern logic.

Click patterns

Button has several click patterns, which allows to control multiple actions by clicking with different time intervals.

Click pattern Description
1 Click Button is pressed not longer than 2s.
2 Clicks Button is pressed not more than two times. If button was pressed more than 2 times, then double click will not be detected. Time between clicks can’t be longer than 1s.
Long Press Button is pressed and held for 2s to 5s.
Long Hold (Power Off via Button) Button is pressed and held for more than 5s.

Note: If a wrong pattern is pressed, the device will wait for the button to be released plus one second to reset. After the reset, it awaits a new click.

Actions

  • Alarm - Generates high priority alarm event and sends to the server immediately.
  • None - Does not generate any events.
