Product Principle 4-13

Wired network: is realized based on PC module (MAC+PHY) and isolation transformer of IO
board. The network capability is decided by PC module.

Isolation transformer and RJ45 network circuit have to meet the security requirements of
creepage distance.

Wireless network: uses built-in wireless module. The network capability is decided by wireless
module and cables. The regular wireless module only owns Wi-Fi. Purchase the wireless
module integrated with Bluetooth function. Wireless module is mini PCIe half-size card. Wi-Fi
on the wireless module communicates with PC module via PCIe x1, and Bluetooth
communicates with PC module via USB x1.
