RN-374M 802.11 b/g AAA Battery powered Wi-Fi serial Adapter

Product description:
RN-374M 802.11 b/g AAA Battery powered Wi-Fi serial Adapter

The battery powered Wi-Fi serial adapter, RN-374, supports RS422 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 and being able to remotely connect to any Wi-Fi serial adapter in the world.

Please ask for availability, this item has a longer lead-time.

General

HTTP Client
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-374 can wake up and send data to a remote server as an HTML post. This feature allows the RN-374 to be an off the shelf, standalone networking client that does not require any software programming.

Mobile Applications
The RN-374 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-374 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.
