Product Introduction

The T333L is a brand new 4G vehicle tracker. In addition to real-time tracking, the T333L has two-way calling and remote listen-in functions. The T333L provides excellent and stable performance in vehicle tracking and fleet management.

Product Features

Harsh Acceleration/Braking Alert and Impact Alert

You can detect the harsh acceleration/braking alert by setting the limit value. Cautions on device installation:

1. The device should be installed into the vehicle according to the following direction.
2. The device installation angle cannot exceed 15 degrees.

The default harsh acceleration and braking alert values are 150 mG and -180 mG respectively.

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 Meitrack Manager software to adjust the harsh acceleration and braking alert values by every 10 mG. You can also use the D79 command to set the values.
• Impact alert implementation principle is the same as the harsh acceleration and harsh braking, and the parameter value is larger. So this alarm event will only occur when the car is driving fast and there is a collision at the same time If the car is stopped and hit by other vehicles, it will not occur.

Roaming Mode

On the Meitrack Manager page, device parameters in roaming mode differ from that in non-roaming mode. When the device detects that it is in roaming mode, it will be operated according to roaming parameters. This helps to save network traffic and learn about device working status.

Common SMS Commands

Setting Authorized Phone Numbers – A71

SMS sending: 0000,A71,Phone number 1,Phone number 2,Phone number 3
SMS reply: IMEI,A71,OK

Description:

Phone number: A phone number contains a maximum of 16 bytes. If no phone numbers are set, leave them blank. Phone numbers are empty by default.
Phone number 1/2/3: SOS phone numbers. When you call the tracker by using these phone numbers, you will receive SMS notification about the location, geo-fence alert and low power alert. If you need to delete all authorized phone numbers, send 0000,A71. When the SOS button is pressed, the tracker will dial phone numbers 1, 2, and 3 in sequence. The tracker will stop dialing when a phone number responds.

Example:
Sending: 0000,A71,13811111111,13822222222,13833333333
Reply: 353358017784062,A71,OK

Setting Listen-in Phone Numbers – A72

SMS sending: 0000,A72,Listen-in phone number 1,Listen-in phone number 2
SMS reply: IMEI,A72,OK

Description:
When you call the tracker by using the authorized listen-in phone number, the tracker will answer the call automatically and enter the listen-in state. In this way, the tracker will not make any sound.
A maximum of two phone numbers can be set. Each phone number has a maximum of 16 digits. If no phone numbers are set, leave them blank. Phone numbers are empty by default.
If no phone numbers are set and commas are remained, phone numbers set before will be deleted.
If you need to delete all listen-in phone numbers, send 0000,A72.

Example:
Sending: 0000,A72,13844444444,13855555555
Reply: 353358017784062,A72,OK

Setting the Smart Sleep Mode – A73

SMS sending: 0000,A73,Sleep level
SMS reply: IMEI,A73,OK

Description:
When the sleep level is 0 (default value), disable the sleep mode.
When the sleep level is 1, the tracker enters the normal sleep mode. The 4G 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 deep sleep mode. If no event (SOS, button triggered, incoming calls, SMSs, or vibration) is triggered after five minutes, the GPS module will stop, and the 4G module will enter sleep mode. Once an event is triggered, the GPS and 4G 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
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.

Installing the T333L

Installing GPS and 4G Antennas

Connect the 4G antenna to the connector which is labeled “GSM”. The 4G antenna is non-directional, so you can hide it in any place of a vehicle.
Connect the GPS antenna to the connector which is labeled “GPS”. It is recommended that the antenna is facing up to the sky and the antenna side with words is downwards. Secure the antenna by using double-sided tapes.
Note: Do not install the GPS antenna at a metal-covered place.

Installing an I/O Cable

The I/O cable is a 12-pin cable, including the power, analog input, digital temperature sensor input, and negative/positive input and output interfaces .

It can be used as a ground wire connected to an analog sensor.

---|---|---
7 (Input 3)| White and red| Digital input 3 (positive trigger)

Connect to the vehicle ACC cable by default to detect the vehicle ACC status.

8 (AD Input 1)| Blue| Analog input 1 with 12-bit resolution and valid voltage 0–14V

Connect to an external sensor, such as the fuel level sensor.

9 (Fuel level sensor input)| Blue and brown| Analog input 2 with 12-bit resolution and valid voltage 0–14 V

The AD cable is connected to the white plug. The cable is connected to the A53 fuel level sensor by default.

10 (Output 1)| Yellow| Output 1

Valid: low level (0 V) Invalid: open collector

Maximum voltage for output open collector (invalid): 40 V Maximum current for output low voltage (valid): 400 mA

Connect to an external relay to remotely cut off the vehicle fuel cable or

engine power supply.

11 (Output 2)| Yellow and brown| Output 2

Valid: low level (0 V) Invalid: open collector

Maximum voltage for output open collector (invalid): 40 V Maximum current for output low voltage (valid): 400 mA

Connect to an external relay to remotely cut off the vehicle fuel cable or

engine power supply.

12 (1-Wire)| Green| TTL3.3V level

Connect to the A52 digital temperature sensor or iButton by default by using the A61 sensor box.

Note: The DC or AC voltage that is greater than 3.3 V is not allowed.

Otherwise, the device may be damaged.

Power Cable/Ground Wire (Pin 1/2)

Connect the power cable (red) and ground wire (black) to the positive and negative charges of the vehicle battery respectively.

ACC and Door Detection (Pin 5/7)

Note: If input 3 is connected to the “ACC” position, after the engine is started, the platform will read it as ON-OFF-ON. If input 3 is connected to the “Start” position, after the engine is started, the platform will read it as OFF-ON-OFF. If installed correctly, after the engine is started, the platform will read it as OFF-ON.

Output (Pin 10/11)

Note:

• To implement remote fuel/power cut-off, connect the relay to the fuel pump power cable or to the engine power cable in series.
• The white line of the relay must be connected with the power V+, and the yellow line must be connected with the OUT line of the equipment. It cannot be connected backwards. If the connection is wrong, the equipment may burn out.

Sensor Input

• For pin 8 analog input 1, a sensor whose output voltage ranges from 0 V to 6.6 V can be installed. The analog voltage calculation formula is as follows:
  Voltage = (AD x 3.3 x 2)/4096

• Pin 9 is connected to the A53 fuel level sensor by default. You can install the sensor without calculation formula added on the platform. For details, see the MEITRACK Fuel Level Sensor User Guide.

• Pin 12 is connected to A61+A52 temperature sensor or iButton by default. For details, see the MEITRACK Temperature Sensor User Guide and MEITRACK iButton User Guide.

Note:

• The white plug on the T333L harness consists of the power cable (red), ground wire (black), AD2 cable (blue), and SEN cable (green).
• The T333L can connect to a maximum of two A61 sensor boxes. You can install a maximum of eight A52 temperature sensor ports. For details, see the MEITRACK Temperature Sensor User Guide.
