Physical Installation

Mounting Options

The Gateway N8 supports multiple mounting configurations for different deployment scenarios.

Wall Mounting

1. Mark Mounting Points

   • Use mounting holes on rear panel as template
   • Spacing: 100mm horizontal, 60mm vertical
   • Ensure surface can support 500g load

2. Install Mounting Screws

   • Use 2 x M4 screws (not included)
   • Drill pilot holes for drywall/wood installations
   • Leave 2-3mm gap for mounting slots

3. Secure Gateway

   • Align mounting slots with screw heads
   • Slide gateway down to lock in place
   • Verify secure mounting before cable connection

Desktop Placement

• Place on flat, stable surface
• Ensure adequate ventilation (10cm clearance on all sides)
• Position away from heat sources and direct sunlight

Dimensional Requirements

• Dimensions: 150 x 85 x 40mm (W x H x D)
• Clearance Required: 10cm on all sides for ventilation
• Cable Bend Radius: Minimum 25mm for Ethernet/power cables

Power Connection

BLE Version

DC Power (Recommended):

1. Connect 9-36V DC power supply to DC jack
2. Ensure correct polarity (center positive)
3. Use twist & lock feature to secure connector
4. Power LED illuminates immediately

Connector Specifications:

• Outer diameter: 5.5mm
• Inner diameter: 2.1mm
• Center pin: Positive (+)
• Outer barrel: Negative (-)

Power over Ethernet (Alternative):

1. Connect PoE-capable Ethernet switch to RJ45 port
2. Verify PoE standard: IEEE 802.3af (15.4W) or 802.3at (25.5W)
3. Power LED should illuminate within 5 seconds
4. Gateway boots automatically (30-60 seconds)

LTE Version (DC Only)

1. Select Power Supply

   • Voltage: 9-36V DC
   • Minimum current: 1A @ 12V (2A recommended)
   • Use regulated power supply for best performance

2. Connect DC Power

   • Insert DC jack into power port
   • Rotate connector clockwise to lock
   • Verify LED illumination

3. Verify Power Consumption

   • Idle: 0.4W (LED only)
   • Typical operation: 3-5W
   • Peak (LTE transmission): 8W max

Network Connection

Ethernet Setup

For Fixed Network Installations:

1. Connect Ethernet Cable

   • Use Cat5e or Cat6 cable
   • Maximum length: 100m
   • Connect to Gigabit switch for best performance

2. Verify Network Configuration

   • Gateway obtains IP via DHCP by default
   • Check switch port LED for link status
   • Gateway attempts cloud connection within 60 seconds

3. Network Requirements

   • DHCP server on network (for automatic IP)
   • Outbound MQTT over TLS (port 8883) allowed
   • Outbound HTTPS (port 443) allowed
   • NTP access (port 123) for time synchronization
   • DNS resolution available

Firewall Configuration

The gateway requires outbound access to Haltian IoT cloud services. Configure your firewall to allow the following traffic:

Required Outbound Ports:

IP Records:

LTE Setup (LTE Version Only)

For Cellular Backhaul:

1. Connect LTE Antenna

   • Attach external LTE antenna to SMA connector
   • Hand-tighten (do not over-torque)
   • Position antenna vertically for optimal reception

2. Verify Cellular Connection

   • LTE LED indicates connection status
   • Gateway will connect to cellular network automatically
   • Fallback to 3G/2G if LTE unavailable

LTE Bands Supported:

• LTE Cat 4: Check regional specifications
• 3G/2G fallback: Worldwide coverage

Initial Verification

LED Status Indicators

Monitor LEDs for system status:

Cloud Registration

Verify Gateway Registration:

1. Access Haltian IoT Studio

   • Log in to your Haltian IoT account
   • Navigate to Devices → Gateways

2. Locate New Gateway

   • Gateway appears automatically after cloud connection
   • Note gateway UUID for identification

3. Verify Network Connectivity

   • Check “Last Seen” timestamp (should be recent)

Initial Configuration

After successful registration:

1. Set Gateway Name - Assign meaningful name (location, function)
2. Deploy Sensors - Position sensors within range
3. Monitor Network Formation - Verify sensors join mesh network

Cable Management

Best Practices

• Ethernet: Avoid sharp bends, maintain minimum 25mm radius
• Power: Route away from high-voltage lines (>100V AC)
• LTE Antenna: Position for best signal, avoid metal obstructions
• Cable Length: Keep Ethernet under 100m, minimize power cable length

Environmental Considerations

• Operating Temperature: 0°C to 50°C
• Humidity: 0% to 95% RH (non-condensing)
• Ventilation: Ensure air circulation around enclosure
• Protection: IP rating suitable for indoor use only

Post-Installation Checklist

• Gateway physically secured (wall/desktop)
• Power connected and LED illuminated
• Network cable connected (Ethernet)
• LTE antenna connected (LTE version)
• Gateway appears in Haltian IoT Studio
• Gateway named appropriately
• Network connectivity verified

Next Steps

• Configure Network - Set up network parameters
• Deploy Sensors - Position sensors and verify connectivity
