Operation
General
The NET-PATHm has four distinct software components: the Loader, Operating
System (OS), Application (App), and Database. These components are contained in
non-volatile flash memory and share a common file system. The following figure
shows these components.
Figure 3-1. Flash Memory Software Components
Flash memory storage capacity is 16 MB. The flash memory is non-volatile, which
means it retains the data when the power is off. The NET-PATHm maintains a second
file system in SDRAM. This file system is used for general data storage. It retains
stored data only as long as commercial power or battery backup is available. SDRAM
is 64 MB.
The loader boots the NET-PATHm and loads an application or Operating System (OS)
into SDRAM for execution. The OS software loads when the system does not have a
valid application. The OS controls all of the functions required to permit users access
to the NET-PATHm and program it with an application and a database.
The application contains all operating software for the NET-PATHm features. A
license key controls the enabled features. The application software requires a
database. If the application is loaded and no database is present, the NET-PATHm
uses a default database. An NET-PATHm that is in the default state (no application or
no database) offers the OS functions that enable the user to contact the unit and
download the application and/or database.
The database contains all of the configuration parameters, programmed by the user.
When the NET-PATHm ships from the factory, it contains the operating system,
application program, and a default database. The default database provides many
basic power-on parameters used during the installation. The default database
parameters include, but are not limited to:
• Host 1 and Host 2 are set to 9600, 8, N, 1.
• physical sensors input not enabled
• modem configured for North America and auto-answer
These parameters remain active until a new database downloads to the NET-PATHm.
