Large-fleet operators have been using GPS tracking devices to get real-time location information on their vehicles for years, and now the technology is trickling down to small-business applications and consumers. A cellular connection and smartphone interact with existing equipment on your personal vehicle to turn it into a company car in a snap.
ET25 is a small and light GPS tracker with solid GPS tracking capability and connectivity. Featuring a sleek and compact design, the ET25 will provide a detailed report of the vehicle’s location and activities. It is the most effective method of monitoring driving activity of your vehicles. With 100mAh/3.7V Li-Polymer battery, ET25’s weight is 62.5g with dimension 73.8.0*25.9*12.2mm and can be operated at temperature -20℃～ 70℃. With working voltage ranging from 9VDC to 90VDC, it is suitable for many kinds of vehicles. It has build-in GPS ceramic antenna, GSM quad-band antenna. With small volume it can be able to place it in various locations throughout the vehicle. It GPS+LBS positioning function allows the location to be pinpointed in real time or periodically.
Basic settings and functions
Power cut-off alarm
When the electricity supply of device is cut off, alarm message will be send to platform and SOS number.
Low battery alarm
When backup battery is low, alarm message will be sent to platform and SOS number.
Over-speed alarm (default off)
Speed limitation can be set in platform or by SMS. When vehicle’s speed exceeds the pre-set value, over-speed alarm will be sent.
Device will send movement alarm when vehicle moves out the pre-set distance.
Device is in defense status if vibration alarm turned on. When vehicle vibrates several times, the vibration alarm will be triggered.
When the electro-mobile/motorcycle battery’s voltage decreases to a certain value, the power supply between the terminal and electro-mobile/motorcycle will be stopped, otherwise, the electro-mobile/motorcycle would fail to start because of too low voltage.
The red line is positive pole, and black one is negative pole. The orange color line is ACC ON and the yellow one is power cutoff (relay needed).
Wiring diagram (electro-mobile)
Use multimeter to find out the battery’s positive and negative side. Whether the key is in the position of ON/OFF, current battery voltage will show in the multimeter. The way to find ACC line: use multimeter red pen to connect with the ACC wire while the black pen connects with the ground wire. When the ignition key switches to OFF, the voltage is 0V; when the ignition key switches to ON, the current voltage will show up. Power cable connects to the positive and negative pole of the battery. ACC cable connects to electro-mobile ACC line. If the electro-mobile has burglar alarm, the orange line is the ACC line.
Let the rear wheel hang in the air. For safety reason, do not let the wheel touch the ground. Find the control line of the speed regulating handle. The control line is in green or white and on the 3PIN of controller. Use multimeter to detect the voltage of the speed regulating handle. The voltage of the speed regulating handle (ACC ON/Motionless) is 0.8V in default and 4.3-5V at maximum when the speed is at maximum speed. Cut the control line of the speed regulating handle into 2 parts, one side connects to the red line of electronic relay, and the other side connects to the red line of electronic relay, and the other side connects to the brown line of 5V electronic relay connects to the ground line of the speed regulating handle. Please use the 5V electronic ralay specified by the manufacture. If you don’t need the power cutoff function, it is ok to not connect the device’s power line (yellow). Electronic relay needed for power cutoff function.
Wiring diagram (motorcycle)
Use multi-meter to find out the battery’s positive and negative side. The way to find ACC line: use multi-meter’s red pen to connect with the ACC wire while the black pend connects with the ground wire. When the ignition key switches to OFF, the voltage is 0V; when the ignition key swithches to ON, the current voltage will show up. Device power cable connects to the positive and negative pole of the battery. ACC cable connects to electro-mobile’s ACC line.
SOS phone numbers can be set. Alerts will be sent to pre-set SOS number. Send SMS command to the terminal. Command format: SOS, A, phone number 1, phone number 2, phone number 3# “A” means to add new number, for example: SOS, A, 18112345432, 18223456789, 183456789012#. It will reply “OK! SOS1: 18112345432, SOS2: 18223456789, SOS3:183456789012” after set successfully.
Delete SOS number
Send SMS command: SOS, D, phone number 1, phone number 2, phone number 3#. If you want to check current SOS number command: SOS#.
To connect default platform www.tracksolid.com, please send the SMS command below, APN command format: APN, APN name# or APN, APN name, user name, password#. An automatic reply “OK” will be sent in one minute if setup is successful.
To connect other platform, please send the SMS commands blow: SERVER, 1, domain, Port, 0#. It will reply “OK” after set successfully.
Set the center number
If you want to cut off/restore oil by SMS command, you have to set a center number firstly. Only the center can send the cut off /restore oil command to the device. You can set your own mobile number as center number. The command for setting center number is: CENTER, A, mobile number#. It will reply “OK” after set successfully. If you want to delete center number please send: CENTER, D#. Only the SOS number can be used to add or delete center number successfully. There is only one center number can be set.
