USB3.1 Gen1
The two USB3. Gen1 ports are implemented by the native xHCI (eXtensible Host Controller Interface) controller and are backward compatible with USB 2.0, USB 1.1, and USB 1.0 devices. Legacy USB support is also provided so you can use a USB keyboard/ mouse in a DOS environment xHCI driver is supported natively in Windows 10.
USB2.0 Port
The two USB2.0 ports are implemented via native xHCI (eXtensible Host Controller Interface) and are backward compatible with USB 1.1 and USB 1.0 devices. Legacy USB support is also provided so you can use a USB keyboard/ mouse in a DOS environment. xHCI driver is supported natively in Windows 10.
2.5G Ethernet Port/ IEEE 802.3at Power over Ethernet
The system offers three 2.5Gb Ethernet ports using an Intel® I225 GbE controller. From right to left, they are ports #1, #2, and #3. Ports #2 and #3 ( in blue ) also offer Power over Ethernet (PoE) connectivity.
The LEDs on the RJ45 connector indicate connection status and speed. The PoE ports supply both power and data on a standard CAT-5/CAT-6 Ethernet cable. Acting as a PSE (Power Sourcing Equipment), compliant with IEEE 802.3at, each port delivers up to 25W to a Powered Device (PD). PoE automatically detects if the connected device is PoE PD or not, making it compatible with standard Ethernet devices as well.
Active/Link LED (Right)
| LED Color | Status | Description |
| Off or Yellow | Off | The Ethernet port is disconnected |
| On | The Ethernet port is connected and no data transmission | |
| Flashing | The Ethernet port is connected and data is transmitting/receiving |
Sneed LED (Left
| LED Color | Status | Description |
| Off, Yellow, Green, or Orange | Off | 10/ 100 Mbps |
| Green | 1000 Mbps | |
| Yellow/ Orange | 2500 Mbps |
System Status LED
There are four LED indicators on the front panel: PWR, HDD, WDT, and IGN. The descriptions of these four LEDs are listed in the following table.
| Indicator | Color | Description |
| PWR | Green | Power indicator, lid when the system is on |
| HDD | Red | Hard drive indicator, flashing when SATA HDD is active |
| WDT | Yellow | Watchdog timer indicator. flashing when watchdog timer has started |
| IGN | Yellow | The ignition option (MezlO-V20) is applied, and this LED is used to indicate ignition signal status (lid when IGN signal is applied). |
DisplayPort
The system has two DisplayPort (DP) outputs which are digital display interfaces that mainly connect video sources and carry audio to a display device. When connecting a DP, it can deliver up to 4K UHD (4096 x 2160 @ 60Hz) in resolution. The system is designed to support a passive DP adapter/ cable. You can connect to other display devices using a DP-to-HDMI cable or DP-to-DVI cable.
The system supports dual independent display outputs by connecting display devices with DisplayPort connections. To support dual display outputs and achieve the best DisplayPort output resolution in Windows, you need to install corresponding graphics drivers
3-pin Terminal Bloc
The system accepts a wide range of DC power input from 8 to 35V via a 3-pin pluggable terminal block, which is fit for field usage where DC power is usually provided. The screw clamping mechanism on the terminal block offers connection reliability when wiring DC power.
Warning
Please make sure the voltage of DC power is correct before you connect it to the system. Supplying a voltage over 35V will damage the system.
