2Product Introduction
The T366 series of products is a vehicle GPS tracker with IP67 water-resistance rating and can be installed into cars,
motorcycles, yachts, and boats. It is equipped with built-in GPS and GSM antennas. The unit can work well in
extreme environments.
2.1 Product Features
2.1.1 Harsh Acceleration/Braking/Harsh Cornering Alert
You can detect the harsh acceleration/braking/Harsh Cornering alert by setting the limit value.
Note: The alert results vary according to the device installation, vehicle model, vehicle weight, and driving
behaviors. After the device has been installed properly, you can use the BBD command,BC6 command and Meitrack
Manager software to adjust the harsh acceleration and braking alert values.
2.1.2 GPS Data Filtering
The GPS data filtering function can ensure GPS data accuracy and eliminate static drift.
You can set the following parameters by Meitrack Manager: GPS speed range, GPS positioning accuracy, and
Number of GPS satellites. When the GPS data filtering function is enabled, if all conditions are met, GPS data will
be updated.
Note: This function can be enabled by Meitrack Manager.

2.1.3 Activating Output by Event
You can activate output by event.
For example:
1. When speeding is detected, the device can control buzzer sounds.
2. When unauthorized ignition or GPS antenna cut-off is detected, the engine will not be able to start.
3. When iButton triggering is detected, the device can control engine startup.
4. When input or output status is detected, the output will be active or inactive.
2.1.4 Idling Detection
This function is used to detect whether a vehicle's engine is switched off while parking. To enable the function, you
must connect input 2 to ACC detection.
When the device detects that the driving speed is 0 and the ACC is on for one consecutive minute (default time), an
idling alert will be generated.
For details, see section 6.5.4 "Setting the Idling Alert –B14."
2.1.5 Changing I/O Port Mode
This function is used to change the I/O port mode. For example, change active negative input to analog port or
positive input.
For details, see section 6.5.6 "Setting I/O Port Status –C08."
2.1.6 Auto Arming
You can enable the auto arming function by B27 command, Meitrack Manager software or MS03 tracking platform.
This function is disabled by default.
When the device is in sleep mode and the function has been enabled, the device will enter auto arming state.
You can set disarming by B21 command.

device will dial the authorized phone numbers in
sequence and send a vehicle theft alert by SMS or
GPRS. The buzzer will make sounds for five
consecutive minutes. During this period, you can
disable the arming state and then the buzzer will
stop buzzing.
Note:
1. To implement the fuel/power cut-off function for a vehicle theft alert, you should select the vehicle theft
event in the Output 1 column on the Meitrack Manager software.
2. To implement the alert function of the buzzer, you should set the 1-Wire interface (green cable) to alert
output.
2.1.7 Starting the Engine by RFID/iButton
After swiping the authorized RFID card or the authorized iButton key touches the iButton reader, the driver must
start the engine within 1 minute. Otherwise, the tracker's output 1 will be triggered (engine cut-off), and thus the
driver cannot start the vehicle. At the moment, if you want to start the engine, you must swipe the iButton
key/RFID card again.
Before starting the engine, ensure that:
1. The tracker's input 2 is connected to the engine detection cable.
2. An iButton key or RFID card has been authorized.
3. The tracker's output 1 is connected to the engine control cable through a relay.
4. The RFID ignition function has been enabled by Meitrack Manager or MS03 tracking platform.
5. The RFID event has been enabled on Meitrack Manager.

6.5.3 Setting the Smart Sleep Mode – A73
SMS sending: 0000,A73,Sleep level
SMS reply: IMEI,A73,OK
Description:
When the sleep level is 0, the sleep mode is disabled (default).

MEITRACK T366_series of products User Guide
Copyright © 2021 Meitrack Group All rights reserved. - 15 -
When the sleep level is 1, the tracker enters the normal sleep mode. The 3G module always works, and the GPS
module occasionally enters the sleep mode. The tracker works 25% longer in the normal sleep mode than that in
the normal working mode. This mode is not recommended for short interval tracking; this will affect the route
precision.
When the sleep level is 2, the tracker enters the deep sleep mode. If no event (SOS, button changes, incoming calls,
SMSs, or vibration) is triggered after five minutes, the GPS module will stop working, and the 3G module will enter
sleep mode. Once an event is triggered, the GPS and 3G modules will be woken up.
Note: In any condition, you can use an SMS command to disable the sleep mode, and then the tracker exits the
sleep mode and returns back to the normal working mode.
Example:
Sending: 0000,A73,2
Reply: 353358017784062,A73,OK
6.5.4 Setting the Idling Alert – B14
SMS sending: 0000,B14, Consecutive Time (second),Speed (km/h),Alert Time (second)
SMS reply: IMEI,B14,OK
Description:
The function is used to detect idling. The tracker must be connected to ACC detection. Otherwise, the function will
be unavailable.
Time: indicates the consecutive time for the speed and alert time. The parameter value ranges from 0 to 60000.
Unit: second.
Speed: The parameter value ranges from 0 to 200. Unit: km/h. (5 km/h is recommended.)
An idling alert will be generated when the following conditions are met simultaneously: the device detects that the
ACC is on; the speed is lower than the preset value; and the consecutive time for the speed is larger than the preset
value.
If you want to read the parameters, send B14.
Note: The alert activation conditions may be affected due to static drift. Therefore, you are advised to set the speed
to a value between 5 km to 10 km and the consecutive time for the speed to a value that is larger than 60 seconds.
The Alarm time is temporarily closed, any parameter can be set first and it is advised to set to 0.
Example:
Sending: 0000,B14,60,5,0
Reply: 353358017784062,B14,OK
For details about SMS commands, see the MEITRACK SMS Protocol.
Note:
1. The default SMS command password is 0000. You can change the password by using Meitrack Manager and
SMS command.
2. The device can be configured by SMS command with a correct password. After an authorized phone number is
set, only the authorized phone number can receive the preset SMS event report.
6.5.5 Controlling Output Status – C01
SMS sending: 0000,C01,Speed,ABCDE
SMS reply: IMEI,C01,OK
Description:

MEITRACK T366_series of products User Guide
Copyright © 2021 Meitrack Group All rights reserved. - 16 -
When the speed is 0, no speed limit exists. That is, when the tracker receives a command, the output control takes
effect immediately.
When the speed is a value ranging from 1 to 255 (unit: km/h), set the speed limit for output control. When the
driving speed is lower than the speed limit, the output control takes effect.
ABCDE: indicates the output 1, output 2, output 3, output 4, and output 5 respectively. When the parameter value
is 0, the output is disabled. When the parameter value is 1, data will be generated according to preset output mode.
When the parameter value is 2, previous status will be remained.
