DH810
Hardware Compatibility & Specs
Which processors are compatible with the DH810?
The DH810 features the LGA1851 socket and supports Intel Core Ultra 200 series (“Arrow Lake-S”) processors.
- TDP Limit: Maximum 65W Base TDP.
- Architecture: Hybrid architecture (Performance-cores & Efficient-cores) is supported.
- Graphics Requirement: You must use a processor with integrated graphics. Intel F-series CPUs (e.g., Core Ultra 7 265F) are not compatible as the unit relies on the iGPU for video output.
What type of memory does the DH810 require?
The system uses DDR5 memory.
- Form Factor: 262-pin SO-DIMM.
- Speed: Supports DDR5-5600.
- Capacity: Max. 48 GB per module, total maximum 96 GB (2 slots).
- Voltage: 1.1 V.
- Error Correction: ECC or Registered memory is not supported.
Does the DH810 support PCIe Gen 5.0 for M.2 SSDs?
No. The primary M.2-2280M slot supports PCI-Express Gen 4.0 x4 (NVMe) and SATA v3.0. It is backward compatible with Gen 3.0 SSDs but will not utilize Gen 5.0 speeds.
Installation & Configuration
How do I configure the COM ports voltage (Pin 9)?
The back panel features two RS232 ports. COM1 can be reconfigured to RS422/RS485 in the BIOS.
Pin 9 Voltage: By default, Pin 9 functions as a Ring Indicator (RI). It can be configured to supply 5V or 12V via Jumper JP2 on the mainboard.
- Warning: Ensure the connected device matches the voltage setting to avoid hardware damage.
- Limit: Max current is 500mA per connector.
Can I operate the DH810 with a 12V power source?
Yes. While the included power adapter provides 19V, the DC-input of the chassis supports a wider input voltage range:
Supported Input: 19V (±5%) or 12V (±5%).
This allows integration into 12V environments (e.g., automotive or industrial rails) without an additional voltage converter.
How do I enable "Power-On after Power-Fail"?
There are two methods:
- BIOS (Software): Set “Power-On after Power Fail” to “Power On” in the Power Management Configuration.
- Jumper (Hardware - Recommended for remote/unattended access): Remove Jumper JP1. This forces the system to start immediately when power is applied, bypassing the BIOS logic which can sometimes fail after very short power interruptions.
Network & Connectivity
Which LAN port should I use for Wake-on-LAN (WOL)?
You should use the 2.5G LAN port (Left, Intel i226). While both ports support network activity, the BIOS logic for “Power On by LAN” after a power failure is technically tied to the 2.5G controller. The 1G port (Intel i219) may not reliably wake the system from an S5 state after a power loss.
Display & Graphics
Does the DH810 support three independent displays?
Yes, natively. The available outputs are:
- HDMI 2.1 (Supports up to 8K @ 60Hz).
- DisplayPort 1.4a.
- USB-C / USB4 (Supports DP alt mode).
All three can be active simultaneously.
Note: An optional VGA port (Accessory PVG01) can be installed, but it replaces one of the COM ports.
Environment & Operational Limits
What are the requirements for operating at 50°C ambient temperature?
The DH810 is rated for 0~50°C. However, for operation above 40°C, you must use:
- Industrial-grade SSDs (rated for at least 70°C).
- High-temperature SO-DIMM memory (rated for up to 95°C).
Standard consumer components may throttle or fail under continuous load at these ambient temperatures.
