4. Setup Guide

4.1. Pre-Installation Checklist

• Ensure the vehicle's battery is fully charged and in good condition.
• Verify you have all necessary cables and connectors for your specific vehicle model.
• Have access to the vehicle's OBD-II port or other designated connection points.
• Confirm network coverage (Verizon) in the installation area.

4.2. Device Placement

For optimal GPS signal reception, place the LMU-3640 in a location with a clear view of the sky, away from large metal obstructions. Common installation points include under the dashboard, near the windshield, or in the glove compartment. Ensure the device is securely mounted to prevent movement during vehicle operation.

4.3. Wiring and Connection

1. Power Connection: Connect the device to a constant 12V or 24V power source in the vehicle. Ensure proper grounding. Refer to your vehicle's wiring diagram for appropriate power points.
2. Ignition Sense: Connect the ignition sense wire to a circuit that is active only when the ignition is on. This allows the device to detect vehicle operational status.
3. ECU/OBD-II Connection (Optional): If utilizing ECU data, connect the appropriate cable from the LMU-3640 to the vehicle's OBD-II port or other CAN bus interface.
4. Antenna Connection (if external): If your model uses an external GPS or cellular antenna, connect it securely to the designated ports on the device.

Caution: Incorrect wiring can damage the device or vehicle electronics. If unsure, consult a qualified automotive technician.

4.4. Initial Power-Up and Status Indicators

Once connected, the device will power on. Observe the LED indicators (if present) for status. Typically, a solid green LED indicates power, a blinking green indicates GPS lock, and a blinking blue/amber indicates cellular network activity. Refer to the device's specific LED guide for detailed interpretations.

5. Operating Instructions

5.1. System Activation

After physical installation, the LMU-3640 requires activation on the CalAmp telematics platform. This typically involves registering the device's serial number and IMEI with your service provider. Follow the instructions provided by your fleet management software or service provider for activation.

5.2. Data Transmission

Once activated and powered, the device will automatically begin transmitting data (GPS location, vehicle diagnostics, accelerometer events) to the designated server via the Verizon cellular network. Data can be viewed and managed through your fleet management portal.

5.3. Event Configuration (PEG™)

The Programmable Event Generator (PEG™) allows for custom event triggers. These can be configured via the CalAmp management system (PULS™) or your service provider's platform. Examples include alerts for geofence entry/exit, excessive idling, harsh driving, or specific engine fault codes.

• Access the configuration portal.
• Navigate to the PEG™ rules or event settings.
• Define conditions (e.g., speed > 70 mph for 10 seconds).
• Specify actions (e.g., send alert, record event).
• Apply changes to the device over-the-air.

6. Maintenance

• Regular Inspection: Periodically check the device and its connections for any signs of wear, damage, or loose wiring.
• Firmware Updates: Firmware updates are typically managed over-the-air via PULS™. Ensure your device is configured to receive these updates to benefit from the latest features and security enhancements.
• Cleaning: Keep the device free from dust and debris. Use a soft, dry cloth for cleaning. Do not use liquid cleaners directly on the device.
• Environmental Conditions: Ensure the device operates within its specified temperature and humidity ranges to prevent damage.

7. Troubleshooting

If troubleshooting steps do not resolve the issue, please contact CalAmp technical support or your service provider for further assistance.
