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 HTTPS (port 443) allowed
   • NTP access (port 123) for time synchronization
   • DNS resolution available

Network Ports Required:

WiFi Setup (Optional)

For Wireless Backhaul:

1. Access Configuration Interface

   • Connect via Ethernet initially
   • Access web interface at gateway IP
   • Or use serial console (internal access)

2. Configure WiFi Credentials

   • Enter SSID and passphrase
   • Select security mode (WPA2/WPA3 recommended)
   • Save configuration

3. Verify Connection

   • WiFi LED indicator shows status
   • Gateway will connect to configured network
   • Fallback to Ethernet if WiFi unavailable

WiFi Specifications:

• Standards: 802.11 a/b/g/n/ac
• Frequency: 2.4 GHz and 5 GHz
• Security: WPA2-PSK, WPA3-PSK

LTE Setup (LTE Version Only)

For Cellular Backhaul:

1. Install SIM Card

   • Power off gateway
   • Insert micro SIM card (metal contacts facing down)
   • Push until click is heard
   • Power on gateway

2. Connect LTE Antenna

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

3. Verify Cellular Connection

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

SIM Requirements:

• Format: Micro SIM (3FF)
• LTE bands: Operator must support Cat 4 bands
• APN configuration: Usually automatic, can be configured if needed

LTE Bands Supported:

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

Initial Verification

LED Status Indicators

Monitor programmable 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
   • Verify firmware version

3. Verify Network Connectivity

   • Check “Last Seen” timestamp (should be recent)
   • Review connection type (Ethernet/WiFi/LTE)
   • Monitor signal quality metrics

Initial Configuration

After successful registration:

1. Set Gateway Name - Assign meaningful name (location, function)
2. Configure Wirepas Settings - See Configuration page
3. Deploy Sensors - Position sensors within range
4. 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
