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 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.
