One-way JACE communications with alarm “hopping”

In this use case, the Supervisor must have a public IP address. The GPRS-equipped JACE can initiate communications to the Supervisor for alarms and exporting histories. Note that the addition of the hub or switch connecting the remote JACEs also allows for alarm “hopping” to the Supervisor.

As shown in Figure 2, a notebook PC running Workbench can attach directly to the hub of the remote JACEs. This type of connection is needed to perform JACE platform maintenance (upgrades, etc.).
