2. Specific Technical Wiring Diagrams

Standard Vehicle Installation (4-Pin Connector)

Most TK and GOT series devices use the following standardized wiring harness:

  • Red (1#): Power (+). Connect to 9V-72V DC constant vehicle power.
  • Black (2#): Ground (-). Connect to the vehicle chassis or battery negative.
  • Orange (3#): ACC / Ignition. Connect to the vehicle’s ignition line to detect engine ON/OFF.
  • Yellow (4#): Relay Control. Connect to the relay trigger wire (Pin 86) for remote fuel/power cut.

Asset Tracker (GPT Series)

Typically Wireless/Magnetic. Charge via Micro-USB or Type-C. Ensure the magnetic side is attached to a flat metal surface with a clear view of the sky (or through plastic/glass).

3. SMS Configuration Commands

Configure your device by sending the following SMS strings to the SIM card number inside the unit. (Note: Replace ‘apn_name’ with your local carrier settings).

// 1. Set APN
APN,internet# (Simple)
APN,apnname,user,password# (With Auth)

// 2. Set Server & Port
SERVER,0,123.123.123.123,5064# (IP Mode)
SERVER,1,yourdomain.com,5064# (DNS Mode)

// 3. Set Reporting Time (Upload Interval)
TIMER,10,3600# (10s when moving, 1 hour when stopped)

// 4. Check Status
PARAM# (Returns IMEI, APN, and Server Settings)
STATUS# (Returns Battery, GPS, and GPRS link status)

// 5. Remote Relay (Fuel Cut)
RELAY,1# (Stop Engine – Active)
RELAY,0# (Restore Engine)

4. Server Integration Steps

  1. SIM Card: Ensure the SIM card has SMS and GPRS data enabled. Disable the PIN code.
  2. Hardware Boot: Connect power. The Red LED (GSM) should flash. Once it flashes slowly, GPRS is active.
  3. GPS Fix: The Blue LED (GPS) should stay solid or flash indicating a 3D fix.
  4. Platform Add: Log into your tracking software, select the Eelink protocol, and add the device using its 15-digit IMEI number.
