3.9 Status of the EXPLORER 540

There are basically three ways of getting status from the EXPLORER 540:
• Access the built-in web interface. The Status page shows information such as
terminal status, network status, position status and ongoing communication. See
Status information on page 4-10.
• Send the SMS command GETINFO to the EXPLORER 540. This commands retrieves
information from the EXPLORER 540 such as call time, data usage, GPS position
and global IP address. For details, see ATCO commands on page B-10.
• I/O pins
• 2-GPO (Terminal ready output).
• 3-GPIO, see next section.
Additionally, until installation is completed you can use the LED to follow the status.
See LED on page 5-9.
3.9.1 Terminal ready signaling with 2-GPO
2-GPO signals when the terminal is registered on the BGAN network and is ready to
communicate with connected equipment. Used in combination with a relay, you can
use this signal to switch on connected equipment when the terminal is ready.
For configuration (Active High or Low), see GPIO pins on page 4-45.
For specifications, see I/O connector (X5) on page A-5.
