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.

What type of memory does the DH810 require?

The system uses DDR5 memory.

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.

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:

  1. BIOS (Software): Set “Power-On after Power Fail” to “Power On” in the Power Management Configuration.
  2. 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:

  1. HDMI 2.1 (Supports up to 8K @ 60Hz).
  2. DisplayPort 1.4a.
  3. 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:

Standard consumer components may throttle or fail under continuous load at these ambient temperatures.
