IHD use with the WiFi / mobile phone / laptop via WiFi / ZigBee Gateway (SM-321) wireless sensor network management: This mode allows devices to access more traditional wireless sensor networks. Even the ubiquitous cell phone, as long as the software is installed SilverHome can act as a management device, greatly enriched the scalability of the system, truly open-minded technical specification supports bidirectional UART TTL transparent conversion with Wi-Fi interface. The maximum baud rate 38400 UART. Support IEEE802.11b / g protocol. Supports two wireless connection: AP Zhan style and Ad-hoc connection mode. Stable data transfer mode: TCP Server / Client mode to ensure the reliability of data transmission networks. Easy data transfer modes: simple UDP data transfer mode support from the gateway to access the Internet. Support DHCP and static IP access. WEP wireless encryption technology. Sleep mode and wake-up mode significantly reduces power consumption. Hardware flow control to achieve high-speed data transmission. WEB browsers do support from the line parameters.
