Hummlink HM-G8 Fanless Industrial Mini PC | Intel Core i5/i7, Dual 2.5GbE LAN, 6x COM RS485, 9-36V DC Phoenix Input

Hummlink HM-G8 is a heavy-duty, fanless industrial mini PC engineered around high-performance Intel Core i5 and i7 processors (8th to 10th Generation, 15W TDP). Designed for mission-critical 24/7 continuous operation in harsh industrial automation, machine vision, and edge computing environments, the HM-G8 integrates dual Intel i225-V 2.5GbE LAN ports, 6 DB9 COM serial ports (with 4 supporting hardware-selectable RS422/RS485), an isolated 14-pin GPIO terminal block (7-in/7-out), and dual Phoenix terminal DC inputs supporting 9V–36V wide-range voltage.

Target Applications

• Industrial Automation & SCADA / PLC Gateways: High-density serial integration (6x COM, 4x RS422/RS485) and 14-pin GPIO facilitate seamless data acquisition from PLCs, frequency converters, sensors, and legacy machinery into centralized SCADA platforms.
• Machine Vision & High-Speed Optical Inspection: Dual Intel i225-V 2.5Gbps Ethernet interfaces deliver low-latency, high-bandwidth data pipes for multi-camera GigE vision capture and AI visual defect detection.
• CNC Machining & Factory Automation Hubs: Heavy-duty fanless aluminum extrusion chassis blocks airborne metal dust, oil mist, and electromagnetic interference (EMI) for uninterrupted 24/7 compute.
• Intelligent Fleet Logistics & In-Vehicle AGVs: Wide 9V–36V DC Phoenix terminal input, AT/ATX ignition mode toggle, and onboard SIM card slot with 4G LTE cellular connectivity make the HM-G8 an ideal autonomous mobile robot (AMR) controller.

Key Hardware Highlights

• Dual Intel i225-V 2.5GbE Ethernet: Up to 2500 Mbps high-throughput networking for industrial vision, real-time control networks, and edge-to-cloud telemetry.
• 6 DB9 COM Serial Ports: 4x RS232/RS422/RS485 multi-mode switchable COM ports plus 2x RS232 COM ports for extensive legacy and fieldbus connectivity.
• 14-Pin GPIO Terminal Block: 7-channel isolated digital inputs and 7-channel isolated digital outputs for direct trigger and relay control.
• Wide DC 9V–36V Power Input: Dual industrial Phoenix terminal blocks (2-Pin front + 3-Pin rear) provide flexible, vibration-resistant power wiring for field enclosures and vehicle batteries.
• Dual-Channel DDR4 SO-DIMM: Supports up to 64GB DDR4 high-speed RAM for multi-threaded industrial workloads.
• Triple High-Speed Storage: 1x M.2 NVMe 2280 PCIe SSD slot + 1x mSATA 3.0 slot + 1x 2.5-inch SATA 3.0 SSD/HDD bay.
• Independent Dual Display: 1x HDMI 1.4 (4K @ 30Hz) + 1x VGA (1920x1200 @ 60Hz) supporting dual mirrored or extended monitoring workstations.
• Cellular & Wireless Expansion: Half-size Mini PCIe for WiFi/BT + Full-size Mini PCIe for 4G LTE with an integrated SIM card slot and dual external SMA antennas.
• Industrial Rugged Reliability: Hardware Watchdog timer (0–255 sec), Auto Power On (AWAL), RTC Wake-up, PXE Boot, Wake-on-LAN, and external CMOS clear / reset buttons.

Frequently Asked Questions (FAQ)

Q: How do I switch COM ports between RS232, RS422, and RS485 on the HM-G8?
A: COM1 through COM4 feature hardware-configurable transceivers. Operating modes can be switched directly via onboard jumpers or within the AMI BIOS interface. Pin definitions for RS422 (TX+, TX-, RX+, RX-) and RS485 (Data+, Data-) are silk-screened on the motherboard and detailed in the Hummlink hardware reference manual.

Q: Can the HM-G8 be powered directly from an industrial 24V DC bus or vehicle battery?
A: Yes. The HM-G8 incorporates wide-range 9V–36V DC buck-boost power circuitry with over-voltage and reverse-polarity protection. Dual Phoenix screw-terminal connectors allow direct, secure wiring to standard 12V or 24V industrial rails without requiring an external DC-DC converter.

Q: What operating systems are supported, and are Intel i225-V 2.5GbE drivers pre-configured?
A: The system supports Windows 10, Windows 11, Windows 10 IoT Enterprise, and major Linux distributions (Ubuntu 20.04/22.04 LTS, Debian, CentOS). Linux kernels 5.4 and newer have native support for the Intel i225-V Ethernet controller. Units ship with Windows 10 Pro pre-installed for testing; unactivated or Linux configurations can be specified at checkout.

Q: Does the unit support unattended remote restarts and automatic power recovery?
A: Yes. Hardware Auto Power On (Restore AC Power Loss / AWAL) is supported and can be toggled via the front AT/ATX hardware switch or configured in the BIOS. The integrated hardware Watchdog timer (0–255 seconds) automatically reboots the system in the event of an OS freeze or application crash.

Q: Do you offer custom branding, specific RAM/SSD configurations, and bulk volume pricing?
A: Absolutely. Hummlink provides complete OEM/ODM services, including custom BIOS boot logos, laser-etched chassis branding, specialized I/O bracket modifications, and custom component loading (e.g., specific Kingston, Samsung, or Micron memory/storage). Contact our B2B engineering team for volume tiers starting from 5 units.
