Tracker

Product Information

Specifications:

• Sleep Modes: GPS sleep, Deep sleep, Online Deep sleep, Ultra
  sleep mode

• Power Usage: Decreases in sleep modes to save vehicle
  battery

• Device Requirements: Movement detection, ignition status, SMS
  messages

• Compatibility: Firmware 03.18.15 and above

Product Usage Instructions

GPS Sleep Mode:

FTC881 enters GPS sleep mode under specific conditions to save
power:

• GPS module turns off
• New periodic records continue
• Device time synchronized with GPS satellites
• Movement not detected, ignition off, no incoming SMS
  messages

Deep Sleep Mode:

FTC881 enters deep sleep mode to save power while maintaining
last known coordinates:

• GNSS receiver sleeps, GSM/GPRS module turns off
• Data sent to AVL server before turning off GSM/GPRS module
• Device time synchronized with GPS satellites
• Ignition off

Online Deep Sleep Mode:

Similar to deep sleep mode but maintains connection to GSM
network:

• GSM part stays powered, increased power consumption
• SMS and call functionalities available
• GPRS context not closed if previously opened

Frequently Asked Questions (FAQ)

Q: How can I enable GPS sleep mode on my FTC881 device?

A: To enable GPS sleep mode, ensure your device meets all the
conditions mentioned in the user manual. Set the sleep timeout and
configure the device to work in GPS sleep mode.

Q: Can FTC881 exit deep sleep mode automatically?

A: Yes, FTC881 exits deep sleep mode if movement is detected by
the accelerometer or if the configured ignition source is turned
on.

Q: What is the difference between deep sleep and online deep

sleep modes?

A: The main difference is that in online deep sleep mode, the
device maintains connection to the GSM network, allowing SMS, call
functionalities, and keeping the GPRS context open.

Video Demonstration
Here is a visual demonstration of the sleep modes and how they they affect the device.
GPS Sleep mode
FTC881 is able to go into GPS sleep mode if such mode is enabled. Sleep mode timeout starts counting when the device is in STOP mode. After timeout is reached and all conditions for GPS sleep mode are met, the device goes into sleep mode.
When in GPS sleep mode, FTC881 turns the GPS module off and continues making new periodic records. As a result power usage decreases, in turn saving vehicle battery. FTC881 will enter GPS sleep mode if ALL of these conditions are met:
FTC881 is configured to work in GPS Sleep mode and sleep timeout is reached; Device time must be synchronized with GPS satellites. From Firmware 03.18.15 version, this condition depends on the “Records saving/sending without TS” parameter:
After Position Fix – FTC881 time is synchronized with GNSS satellites and GPS fix is obtained; After Time Sync – FTC881 time is synchronized over NTP, NITZ, or GNSS satellites; Always – FTC881 will enter sleep mode without time synchronization and GPS fix.
Movement is not detected by the accelerometer and configured movement source; Ignition (configured ignition source) is off;

There are no SMS messages being received.
FTC881 exits GPS sleep mode if ONE of following conditions is true:
Movement by accelerometer or configured movement source is detected; Ignition (configured ignition source) is turned on.
Deep Sleep mode
While in deep sleep mode, FTC881 sets the GNSS receiver to sleep mode and turns off GSM/GPRS module (hence it is not possible to wake up the device via SMS). Despite records with the last known coordinate being saved and sent to the AVL server (GSM/GPRS module is turned on to send data and then it is turned off), power usage is decreased to save the vehicle’s battery.
Please note that power saving depends on two configurable parameters: Send Period and Minimum Record Saving Period in “X on Stop Mode”. When records are sent successfully in deep sleep mode, open link timeout counter will be skipped and FTC881 will enter deep sleep mode immediately. Because a lot of functions are disabled in deep sleep mode following I/O elements are disabled from records that are generated in this mode: GSM Signal, GNSS Status, GNSS PDOP, GNSS HDOP, GSM CellID, GSM Area Code, Active GSM Operator, Trip Odometer, Total Odometer, Speed, Fuel Rate GPS, Fuel Used GPS and ICCID. FTC881 can enter deep sleep mode if ALL of these conditions are met:
FTC881 is configured in Deep Sleep mode and sleep timeout is reached; Device time must be synchronized with GPS satellites. From Firmware 03.18.15 version, this condition depends on the “Records saving/sending without TS” parameter:
After Position Fix – FTC881 time is synchronized with GNSS satellites and GPS fix is obtained; After Time Sync – FTC881 time is synchronized over NTP, NITZ, or GNSS satellites; Always – FTC881 will enter sleep mode without time synchronization and GPS fix.
Ignition (configured ignition source) is off;
Movement is not detected by the accelerometer or configured movement source; Min. Record Saving Period (Data Acquisition Mode settings) must be larger than Open Link Timeout parameter, so that FTC881 could close GPRS link; The difference between Send Period (Data Acquisition Mode settings) and Open Link Timeout must be more than 90 seconds, so that FTC881 could close GPRS link within at least 90 seconds; There are no SMS messages being received; Data socket(s) are closed; Data sending is not in progress; FOTA is not in progress.
FTC881 exits deep sleep mode if ONE of following conditions is true:
Movement by accelerometer or configured movement source is detected;

Ignition (configured ignition source) is turned on.
Online Deep Sleep mode
In this mode, the device works as in deep sleep mode, but without deregistering from the GSM network. GSM part stays powered so this increases power consumption. In this mode, the device should send/receive SMS and make/accept calls. It does not close the GPRS context if one was previously opened.
Conditions to enter online deep sleep mode are the same as entering deep sleep mode. FTC881 exits online sleep mode if ONE of following conditions is true:
Movement by accelerometer or configured movement source is detected; Ignition (configured ignition source) is turned on.
Ultra Sleep mode
Conditions to enter ultra deep sleep mode, where GPS and GSM modem are turned off and device functions are suspended for maximum battery saving, are the same as entering deep sleep mode. FTC881 exits ultra deep sleep mode only when DIN1 or movement are detected by accelerometer. Movement source and Ignition source configuration is not taken into account in this case.
