Non-Clinical SNI
The Secure Network Interface (SNI) is a miniature Web-server that quickly connects serial devices to a TCP/IP network, eliminating the need for terminal servers and PCs to provide connections. This small unit contains a CPU board that can easily be configured to communicate with any serial device, adds local processing power and intelligence, and makes the data available over the network.
The SNI is most commonly used to provide a standardized interface to large collections of clinical laboratory analytical instruments, but has also been used in a wide variety of nonclinical applications where the capture of data from a serial device is desirable. The SNI can replace more costly and less reliable connectivity products, and provides the user with complete control over the application.
The SNI uses either a static IP address or DHCP to identify itself on the network and is accessed via a standard Web browser from any authorized location.
Data acquisition
Data is captured from the serial device, processed within the SNI and delivered to a designated server on the network or Internet. This is useful when result information is being produced.
Data presentation
Data is captured and processed from the serial device, then stored within the SNI (often as HTML pages) for presentation to a network visitor. This is useful in monitoring applications.
Weather Monitoring
Data is collected through the weather instruments controlled by your main console, which then transmits it to a Dawning Secure Network Interface (SNI). The SNI captures the data, formats it, and stores it, (most often as an HTML page) where it is available for presentation to a network (website) visitor. All of this is done without additional hardware such as PC's and Terminal Servers. By allowing a direct connection, the SNI can enhance network reliability, provide the user improved control over the application, and save you money.
Remote Data Retrieval
Federal Communciations Commission regulations require broadcast stations to have Emergency Alert System (EAS) equipment at each broadcast station to receive and relay information sent through the EAS. Typically this equipment prints activity logs regarding tests and activations received and transmitted. The FCC requires these logs to be reviewed at least once per week. Since the equipment is often at remote locations, weekly visits to retrieve logs can be difficult or expensive. The Secure Network Interface enables radio stations to automatically collect and forward activity logs from these remote locations to a central point.
Emergency Alert System equipment contains serial outputs that can be configured to transmit data to other devices, this provides the connection point for the Secure Network Interface. When a message is received or transmitted by the EAS equipment....
- The log of the event is sent to the SNI.
- The SNI then signals a proxy server that it needs a network connection, if not currently connected to your network.
- The proxy server dials an ISP and makes an Internet connection.
- Once the SNI determines the network connection is present it utilizes FTP to transmit the log to a file server.
- The proxy server then terminates the dial-up connection, and the file is available for review at anytime via a standard web browser.
