Remote Control
The 9502 can be controlled remotely via SMS and locally via AT
commands. The AT interface can be used for local control of the
terminal as long as AT commands can be sent by the terminal
equipment (TE) connected. The syntax of all AT commands is
covered in the “Inmarsat BGAN UT-TE Interface Specification”
and the AT command listing supported by the 9502 can be
downloaded from the Hughes website at
www.bgan.hughes.com
.
The 9502 includes a remote control by SMS feature that supports
the special SMS messages listed in Table 5 – Remote Control SMS
Message Commands. Remote control SMS is supported by default
in the 9502 and does not have to be activated by a feature code.
The syntax of the messages is covered in the “Hughes 9502 SMS
Remote Control Feature User Guide.”
All remote control messages and responses must fit into a single
160 character SMS.
The SMS handler automatically deletes any message that fills the
last SMS slot in the USIM to ensure there is always room to
receive control SMS messages. Control messages are received into
the SIM then read out and deleted so as not to fill up the SIM card.
