What Are Digital Outputs?

Digital outputs are electrical signals from the telematics device that can control external components:

• Relays: Switch high-current devices
• Sirens/Buzzers: Audio alerts
• Lights: Visual indicators
• Immobilizers: Engine cut-off

How They Work

Basic Operation

1. Command sent from platform
2. Device receives command
3. Output changes state (ON/OFF)
4. External device is activated/deactivated

Electrical Characteristics

Specification	Typical Value
Output type	Open collector/drain
Max current	200-500mA
Voltage range	5-30V DC
Switching time	<100ms

Common Applications

Engine Immobilizer

Remotely disable the vehicle:

• Connection: To fuel pump relay or starter circuit
• Use case: Theft prevention, unauthorized use
• Safety: Only activate when vehicle is stationary

Horn/Siren Activation

For alerts and locating:

• Connection: To horn relay or external siren
• Use case: Panic button, vehicle location
• Duration: Configurable activation time

Door Lock Control

Remote locking:

• Connection: To central locking system
• Use case: Fleet security, remote lock
• Type: Pulse output typical

External Indicators

Visual feedback:

• Connection: To LED or warning light
• Use case: Status indication, alerts
• Mode: Steady or flashing

Installation Considerations

Safety First

⚠️ Important precautions:

• Never activate immobilizer while vehicle is moving
• Use proper relays for high-current loads
• Protect circuits with fuses
• Follow local regulations

Wiring

1. Identify output wire on device
2. Plan relay connection if needed
3. Route wiring safely
4. Use appropriate connectors
5. Install fuse in power line

Relay Selection

For loads exceeding device output capacity:

• Use automotive relay (12V/24V coil)
• Match relay contacts to load current
• Consider solid-state relays for high cycles

Platform Configuration

Setting Up Outputs

1. Enable output control in platform
2. Define output behavior (pulse/continuous)
3. Set security permissions
4. Configure confirmation feedback

Control Methods

Method	Description
Manual	Operator activates from platform
Automatic	Triggered by events/geofences
Scheduled	Time-based activation
Conditional	Based on multiple conditions

Best Practices

For Immobilizers

• Require confirmation before activation
• Log all activation events
• Have recovery procedure
• Train operators on proper use

General

• Test thoroughly before deployment
• Document all connections
• Regular inspection of installations
• Keep backup procedures

Troubleshooting

Issue	Possible Cause	Solution
Output not activating	No command received	Check connectivity
Relay not clicking	Insufficient current	Check output type
Intermittent operation	Loose connection	Secure all connections
Fuse blowing	Overload	Check current draw

Conclusion

Digital outputs extend the capabilities of your telematics system beyond tracking. Rinho devices provide reliable output control for various applications.
