Installation Instruction

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.

❌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
