Internal
Architecture
The NRL Internal architecture is shown below. It contains two discrete sections:
1. A LOGGER section where the terminal connects to the field transducers and the
logging scheme, scan rates and diagnostics are managed.
The StarlogV4 support software allows a user to generate a logger program (called a
scheme) which defines transducer information, logging scan rates, logger interval etc
and various engineering unit definitions. These files are called, for example the LDR
and KBD files.
2. A COMMUNICATOR section which deals with communications to the server. This
section contains, for example, a scheduler component and the modem component,
either a Cellular Network modem or a Satellite Network modem. The communicator
manages functions such as the reporting interval, the number of communications
attempts per communications session, etc.
The StarlogV4 support software allows a user to generate a configuration file for the
Communicator section, called an FPO file in which the user sets the required
communications parameters.
