Example1.
The terminal should be configured so that head pack (HeadPack) contains information about the device
version (HardVersion), firmware version (SoftVersion), unique 15 digit GSM unit identity( IMEI), device user
ID (ID device).
Correspondent tag mask: 00000000000000000000000000000001111.
To apply the settings we should use the following command
HeadPack 00000000000000000000000000000001111, or omitting zeros, HeadPack 1111
Example 2. It is necessary to configure the main packet (sent in normal mode) so that the device used ID (ID
device), packet number (NumberOfPacket), date and time of packet record (TimeDate), coordinates are
sent.
Correspondent tag mask: 00000000000000000000000000001111000
To apply the settings we should use the command: MainPack 1111000.
In this case zeros have been omitted at once.
The server can send commands to the device. After command receiving and its successful execution, the
terminal sends packet with reply text.
