Wi-Fi adapter, RS232, Female connnector
** Wi-Fi adapter**
The battery powered Wi-Fi serial adapter, RN-370F, supports RS232 interface and when connected to a remote host it transfers data, read or written, to the serial interface of a remote application such as an iPhone app, data logger or PC control console. Data is transferred over a reliable TCP/IP socket or by using other protocols such as UDP and HTTP. 802.11 b/g infrastructure or ad hoc networking has the advantage of using existing low cost wireless connectivity enabling the user to remotely connect to any Wi-Fi serial adapter in the world. A built in HTTP client can be used to post data to a remote server without the need for any host controller. By simply enabling the HTTP protocol, the RN-370F can wake up and send data to a remote server as an HTML post. This feature allows the RN-370F to be an off the shelf, standalone networking client that does not require any software programming. The RN-370F can easily connect to an iPhone/iTouch. It is a simple unrestricted solution to connect your external device with an iPhone app. Simply setting the device in ad hoc mode allows any Wi-Fi enabled computer or smartphone to control and monitor serial devices. In this mode, the Wi-Fi serial adapter broadcasts an open network that the iPhone/iTouch can connect to. Once the connection is established, data can be transferred between the RN-370 and the iPhone/iTouch app. Applications with multiple TCP/IP sockets can control and monitor hundreds of Wi-Fi serial adapters remotely distributed across your LAN, campus WAN, or any other network.
