I/O Configuration
The Sentry 4G
I/O subsystem is configured via the Sentry 4G
WEB pages. Status Monitoring is
provided via NMEA-based protocol. The Sentry 4G I/O subsystem operates according to a
manager/agent model. The PC-hosted manager sends requests to the Sentry 4G
I/O agent, which
performs the required actions. The Sentry 4G
agent reports alarms and indications to the PC-hosted
manager.
