No COM Ports
COM 1 By cable
COM 2/3/4 By daughter card
Q400P: Delivers 4 native RS232 COM ports (COM1 via external COM cable; COM2/3/4 via internal expansion card since 2026)
perfect for connecting legacy industrial equipment such as PLCs, barcode scanners, CNC machines, and access control panels.
Fully fanless operation with a solid aluminum alloy chassis ensures silent, dust-free performance
ideal for harsh or noise-sensitive environments like factories, hospitals, retail kiosks, and transportation systems.
Supports 1x mSATA SSD (for fast OS boot) + 1x 2.5" SATA HDD/SSD (for bulk data storage)\u2014enabling optimized system architecture and easy upgrades.
Equipped with 1x DDR3 SO-DIMM slot (up to 8GB), offering balanced performance for multitasking and embedded applications.
4. Rich I/O Connectivity for Multi-Device Integration
Dual HD outputs support independent dual displays\u2014ideal for digital signage, surveillance walls, or multi-monitor workstations.
4x USB 3.0 ports deliver high-speed data transfer for cameras, storage, and peripherals; plus 2x USB 2.0 ports for legacy devices like keyboards, mice, or serial adapters.
Dual Realtek Gigabit Ethernet ports enable network redundancy, VLAN segmentation, or direct device-to-device communication\u2014critical for POS systems, factory networks, and security applications.
5. Dual BIOS Boot Modes: UEFI + Legacy Compatibility
BIOS supports both modern UEFI and traditional Legacy boot modes, ensuring seamless compatibility with Windows 7/8/10, various Linux distributions, and older industrial software that requires DOS or non-UEFI environments.
6. Ultra-Compact & Mountable Form Factor
Mini PC size (155*127*48mm) saves valuable space; supports VESA mounting - ideal for tight enclosures, behind displays, or inside machinery.
7. Energy-Efficient In-tel Haswell/Broadwell Processor
Powered by low-voltage 4th/5th Gen In-tel Core i3/i5 or Celeron CPUs (15W TDP), delivering reliable computing performance while maintaining low power consumption - perfect for always-on deployments.
