Discovery Device — Installation & Commissioning

1. Pre-Installation Requirements

Tools & Materials

  • Discovery Device with wiring harness
  • Active SIM card (data enabled)
  • Multimeter – Voltage & continuity checks
  • Wire tap connectors / Crimp terminals – Electrical connections
  • Side cutter / Wire stripper – Cutting & stripping wires
  • Automotive insulation tape / Heat-shrink sleeves – Joint insulation
  • Cable ties – Securing wiring & device
  • Trim removal tools – Dashboard & panel removal
  • Screwdriver set – Opening panels & fixing
  • Fuse tap with blade fuse – Protected battery power

Safety Instructions

 ⚠️ Before starting any work:
  • Turn vehicle ignition OFF
  • Disconnect battery if required by OEM practice
  • Open dashboard using trim removal tools and screwdrivers
  • Avoid routing near:
    • Airbags
    • ECU / ABS lines
    • Steering column & pedals
  • Avoid sharp edges, moving parts, and hot zones
  • Always use a fuse tap with blade fuse for battery connection

2. SIM Installation

  • Open SIM slot .
  • Insert SIM in correct orientation.
  • Ensure:
    • SIM is activated
    • Data plan enabled
    • SIM PIN lock disabled
  • Lock SIM properly.
  • Press Restart / Reset button on PCB.

3. Device Mounting Guidelines

Important Rule:

➡ Device top surface must face the sky for proper GPS reception.

✅ Recommended Locations

  • Inside dashboard near windshield
  • Under plastic trims near A-pillar
  • Under dashboard with sky visibility

❌ Avoid Locations

  • Engine compartment
  • Enclosed metal cavities
  • Near amplifiers / high-current wiring
  • Areas exposed to:
    • High heat
    • Water
    • Continuous vibration
  • Secure the device using cable ties or OEM tape

Ensure no free movement after fixing.

4. Wiring Instructions

Before Wiring

  • Strip wires using wire stripper / side cutter.
  • Prepare terminals using a crimping tool.
  • Use wire tap connectors where required.
Wire Color Pin No. Connect To Purpose Notes
RED
1 Vehicle Battery + (9–90V DC) Main power Must be connected to a constant battery supply (24/7 power). Verify voltage using a multimeter before final fixing. .
BLACK
7 Vehicle chassis ground Ground reference Ensure clean, paint-free metal contact. Verify ground continuity using a multimeter.
GREEN
 2 Vehicle ignition line (12V) Detects ignition state Confirm 12V only when key is ON and 0V when OFF using a multimeter.

⚠️ Critical Ignition Warning

If the GREEN ignition wire is wrongly connected:

  • Device may remain in sleep mode
  • Old / stale location may appear
  • Speed & movement detection may fail

✅ Mandatory Multimeter Verification

Using a multimeter, confirm:

  • RED (Power): Continuous voltage even when engine is OFF
  • GREEN (Ignition): 12V only when key is ON, 0V when OFF
  • BLACK (Ground): Near-zero resistance and noise-free

After wiring:

  • Crimp joints using a crimping tool
  • Insulate all joints using insulation tape / heat-shrink sleeves

5. LED Status — Normal Operation

LED Color Pattern Meaning
Power
Red Solid Power OK
User
Red Blinking Processor working
GNSS
Orange Blink every ~2 sec GPS fix OK
Network
 Green Blink every ~2 sec Network registered 
 ✅If all LEDs match → Device is working properly

6. LED Status — Troubleshooting Guide

LED Behavior Condition Corrective Action
Power
OFF No power Check RED & BLACK using multimeter, verify fuse tap
User
OFF Modem not initialized Reboot using reset button
GNSS
OFF No GPS fix Re-mount device facing sky
Network
 Fast blinking Searching for network Move vehicle to open area, check SIM
Network
 Double blinking SIM not registered Remove & reinsert SIM

7. Commissioning & Validation

  • Perform 2 km road test:
  • Verify on portal using mobile phone or laptop:
    • Live movement
    • Speed updates
    • Ignition ON / OFF events
 ❗ If any point fails → Recheck wiring using multimeter and verify LED status again.

8. Finalization

  • Secure wiring using cable ties.
  • Insulate joints using insulation tape / heat-shrink sleeves.
  • Ensure:
    • No loose wires
    • No rattling noise

Record:

  • Installation date
  • Vehicle Number
  • IMEI

Capture:

  • Photos of power, ground, and ignition connections
  • Photo of device mounting
  • 10-second LED status video using mobile phone

Save all media for future troubleshooting.

Quick Troubleshooting Summary

Issue Likely Cause Fix
No power RED wire or GND issue Check using multimeter, verify fuse tap
Shows old location data Ignition (Green) wire error Recheck GREEN wire using multimeter
No GPS Blocked sky view Change mounting position
No network SIM / signal issue Replace or reinsert SIM
