Configuration
Before a device starts being operated, its parameters should be set first. This
chapter
shows the string to be sent to
device.
There are 3 options of sending string.
Option 1: by using PC.
Option 2: by using GPRS/HSPA network.
Option 3: by messaging via SMS.
In practice, configuration can be made more efficiently with ‘SyncTrak’, i.e. a setting tool provided by Suntech.
Once a device receives a command from the server, it gets back to the server with a relevant response. Device also
changes some parameters (if it is required to do so) or takes an action as instructed below as per the command sent by
the server.
