2.2.2.11 Gigabit Ethernet Connector (CN17)
MIO-2270 uses a Realtek® RTL8111E Ethernet chip (10 / 100 / 1000 Mbps) linked to
a dedicated PCIe x1 lane via RJ-45 connector.
2.2.2.12 CPU Fan Connector (CN18)
The MIO-2270 integrated with a quad-core processor GX-415GA SKU is equipped
with a cooler, that is a 12 V DC fan, as a thermal solution
2.2.2.13 SATA Connector (CN21)
MIO-2270 features one high-performance serial ATA interface. Data transfer rates of
up to 600 MB/s enable extremely fast data and file transfers, as well as independent
DMA operation on two ports.
2.2.2.14 SMBus Connector (CN22)
MIO-2270 features a SMBus connector to connect with SMBus protocol embedded
devices.
2.2.2.15 USB Connectors (CN24 and CN25)
The board provides four USB (Universal Serial Bus) ports, two are rear I/O at coast-
line (CN25), and the other two are internal USB ports (CN24). This offers complete
plug-and-play functionality, and hot attach/detach for up to 127 external devices. The
rear I/O external USB ports comply with USB specifications, Revision. 3.0, and sup-
port up to 5 Gbps. The internal USB interfaces comply with USB specifications, Revi-
sion 2.0, and features a 480-Mbps transfer rate and fuse protection.
Note! Please disable USB3.0 controllers from the BIOS setup manual before
OS installation. The rear I/O USB3.0 ports are only operational after the
OS and USB 3.0 driver are installed.
2.2.2.16 Mini PCIe Connector (CN31)
MIO-2270 supports a half-size mini PCIe slot. The PCI Express Mini Card (also
known as Mini PCI Express, Mini PCIe, and Mini PCI-E) is a replacement for the Mini
PCI form factor based on PCI Express, and was developed by PCI-SIG. The host
device supports both PCI Express and USB 2.0 connectivity.
Advantech also provides SMBus API, which allows developers to interface with
embedded system environments and transfer serial messages using SMBus proto-
cols, facilitating multiple simultaneous device control.
2.2.2.17 Battery Connector (BH1)
MIO-2270 supports a 3 V / 210 mAH CR2032 lithium battery with a wire via a battery
connector (BH1).
Note! To clear CMOS, please follow the steps below:
1. Turn off system power
2. Unplug CR2032 battery cable on BH1
3. Wait 15 seconds or for short BH1 pin1-2
4. Connect the battery cable on BH1
5. Turn on system power
