⚠️ Important Notes
Memory Compatibility: Supports DDR3L SO-DIMM memory modules only (1.35V low voltage). Standard DDR3 (1.5V) modules are not compatible. Maximum supported capacity is 8GB.
Power Supply Requirements: Use a stable, high-quality DC 12V ±5% power adapter with adequate current capacity. For systems with multiple drives or expansion cards, ensure the power supply can deliver sufficient current.
Thermal Management: The fanless design relies on proper heat dissipation through the chassis. When integrating into an enclosure, ensure adequate thermal design and consider ambient temperature. Avoid blocking ventilation paths.
Network Configuration: The optional BYPASS function allows network traffic to pass through during power loss or system failure. Specify this requirement when ordering if needed for high-availability applications.
Serial Port Considerations: One COM port follows CISCO-standard RS232 pinout. Verify compatibility with your serial devices and cables. For custom applications, consult the pinout diagram.
Storage Options: The CF card slot is optional. Confirm with your supplier if this feature is required. mSATA and SATA interfaces support standard storage devices. For industrial applications, consider using industrial-grade storage solutions.
