SECTION 4 SOFTWARE

4-1 OVERVIEW

The MicroCEM Software includes 3 main components. One component is the Micro- CEM control software that interfaces with the instrumentation and records the emissions measurements. A second component is the User Interface Software that provides real- time status and configuration dialogs. A third component is the web server software that uses VB Script or Java Script to provide a web-based interface to the MicroCEM.

4-2 MicroCEM USER INTERFACE SOFTWARE Hardware Platform: Pocket PC

The MicroCEM User Interface Software communicates with the MicroCEM Control Software using TCP/IP. It may run locally on the MicroCEM computer or remotely on a Pocket PC with a RS232 connection to the MicroCEM

computer. It will not normally run locally since there is no input device or display connected to the MicroCEM processor.

4-3 MicroCEM WEB SERVER SOFTWARE

Web Browser: Internet Explorer 4.0 or Net- scape 4.0

The Web Server Software provides the web based interface described in this document. It is implemented as a VB Script or Java Script. The script will obtain much of the needed information directly from the Data-Log files or configuration file. The real-time information will be obtained from a memory segment shared with the MicroCEM control software. The web server support multiple simultaneous clients. The maximum number of allowed connections could be limited to a reasonable number through the Windows CE Web Server configuration dialogs.
