Installation

Proper installation of the VGUANG-M350 is essential for optimal performance and reliable operation. This section provides detailed installation procedures and important considerations.

Pre-Installation Checklist

Before beginning installation, ensure you have:

• ✅ VGUANG-M350 device
• ✅ Appropriate mounting bracket (86mm electrical box compatible)
• ✅ Required tools (screwdriver, wire strippers, etc.)
• ✅ Power supply (12-24V DC)
• ✅ Communication cables (matching selected interface)
• ✅ Access control system ready for integration
• ✅ Configuration tool and configuration completed

Installation Location Considerations

Environmental Requirements

• Lighting: Avoid locations where the scanning window faces direct sunlight or high-intensity lighting. Strong light sources can interfere with QR code recognition and may damage the CMOS sensor over time.
• Metal Interference: Ensure no metal objects or magnetic materials are within 10 cm of the NFC antenna area (located below the scanning window). Metal interference significantly degrades card reading performance.
• Accessibility: Install at an appropriate height for easy scanning (typically 1.2-1.5 meters from ground level).
• Protection: Choose a location protected from excessive dust, moisture, and physical damage.

Mounting Surface

• Standard Electrical Box: The device is designed for installation on standard 86mm electrical boxes.
• Surface Type: Ensure the mounting surface is flat and stable.
• Clearance: Allow adequate clearance around the device for cable management and maintenance access.

Installation Steps

Step 1: Mount the Bracket

1. Position the mounting bracket on the 86mm electrical box.
2. Align the bracket mounting holes with the electrical box holes.
3. Secure the bracket using appropriate screws.
4. Ensure the bracket is firmly attached and level.

Step 2: Prepare Wiring

1. Power Wiring:

   • Connect the positive terminal (VCC) to the 12-24V DC power supply positive.
   • Connect the negative terminal (GND) to the power supply negative/ground.
   • Ensure proper polarity to avoid damage.

2. Communication Wiring (select based on your interface):

   RS485:

   • Connect TX+ to RS485 A+ line
   • Connect TX- to RS485 B- line
   • Connect GND to common ground

   RS232:

   • Connect TX to receiver RX
   • Connect RX to transmitter TX
   • Connect GND to common ground

   TTL:

   • Connect TX to receiver input
   • Connect RX to transmitter output
   • Connect GND to common ground
   • Connect VCC if required (check voltage compatibility)

   Wiegand:

   • Connect D0 to Wiegand D0 line
   • Connect D1 to Wiegand D1 line
   • Connect GND to common ground

   Ethernet:

   • Use standard Ethernet cable (568B wiring)
   • Connect to network switch or access control controller
   • Ensure proper network configuration

3. Relay Wiring (if applicable):

   • Connect COM (common) terminal
   • Connect NO (normally open) or NC (normally closed) as required
   • Ensure relay rating matches your load requirements

4. Door Sensor Wiring (Ethernet + Wiegand version):

   • Connect MC (door sensor) input if required
   • Connect GND for door sensor circuit

Step 3: Secure All Connections

1. Check Wire Integrity: Ensure all wires are properly stripped and not damaged.
2. Secure Terminals: Tighten all terminal screws securely to prevent loose connections.
3. Insulation: Ensure proper insulation between wires to prevent short circuits.
4. Strain Relief: Provide adequate strain relief for cables to prevent damage from pulling.

Step 4: Install the Device

1. Align the VGUANG-M350 device with the mounting bracket.
2. Press the device firmly onto the bracket.
3. Ensure all mounting clips engage properly and the device is securely attached.
4. Verify the device is level and properly oriented.

Step 5: Verify Installation

1. Visual Inspection:

   • Check that the device is securely mounted
   • Verify the scanning window is clean and unobstructed
   • Ensure no cables are pinched or damaged

2. Power Check:

   • Verify power supply voltage (12-24V DC)
   • Check that power indicator LEDs are functioning
   • Confirm device powers on correctly

3. Functional Test:

   • Test QR code scanning with a test code
   • Test NFC card reading with a compatible card
   • Verify communication with access control system
   • Test relay operation if applicable

Post-Installation Configuration

After physical installation:

1. Apply Configuration: If not configured before installation, scan the configuration code to set up the device (refer to Setup & Configuration section).
2. System Integration: Configure your access control system to communicate with the VGUANG-M350.
3. Test Operation: Perform comprehensive testing of all functions.
4. Documentation: Record device location, configuration, and network settings for future reference.

Installation Best Practices

Cable Management

• Use appropriate cable lengths to avoid excess slack.
• Secure cables to prevent strain on connections.
• Use cable management accessories as needed.
• Label cables for easy identification during maintenance.

Power Supply

• Use a dedicated power supply if possible, or ensure the shared power supply has adequate capacity.
• Install appropriate fuses or circuit breakers for protection.
• Verify voltage stability under load.

Network Installation (Ethernet)

• Use quality Ethernet cables (Cat5e or better).
• Avoid running Ethernet cables parallel to power cables to reduce interference.
• Test network connectivity before finalizing installation.
• Document IP addresses and network configuration.

Environmental Protection

• Consider installing a protective cover or housing if the device is exposed to harsh conditions.
• Ensure adequate ventilation if installed in an enclosure.
• Protect from direct water exposure (unless rated for outdoor use).

Common Installation Issues

Device Not Powering On

• Check power supply voltage and polarity
• Verify all connections are secure
• Check for short circuits
• Verify power supply capacity

Poor QR Code Recognition

• Check for strong light sources interfering with scanning
• Clean the scanning window
• Verify code quality and size
• Adjust installation angle if necessary

Poor Card Reading Performance

• Check for metal objects within 10 cm of the antenna area
• Verify card compatibility
• Test with different card positions
• Check antenna area for obstructions

Communication Problems

• Verify wiring connections
• Check interface configuration matches system requirements
• Test with known-good cables
• Verify baud rate and data format settings
