98-148232-E Status of the EXPLORER 540 46
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 56.
• 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 133.
•I/O pins
• I/O pin 2 (Terminal ready output). Connect to this pin for information if the terminal is
registered on the BGAN network and is ready to communicate with connected
equipment. See Power save on page 88 and I/O connector (X5) on page 116.
• GPIO pin 3, see next section.
Additionally, until installation is completed you can use the LED to follow the status. See LED
on page 106.
Control or status with GPIO pin 3
The GPIO pin 3 is configurable in the web interface to be input or output, and active low or
active high. You can use the AT command _ITGPIO to activate or deactivate the pin (if
configured as output) or read the status of the pin (if configured as input).
For configuration, see I/O pins on page 89.
For specifications, see I/O connector (X5) on page 116.
To read the status of GPIO pin 3 (input)
Do as follows:
1. Configure GPIO pin 3 in the web interface to be input.
2. Send the command _ITGPIO? to the terminal.
3. You get a response saying whether the pin is active or inactive (1 is active, 0 is inactive).
Note that the setting in the web interface determines whether the pin is active high or low.
Example: _ITGPIO: 1
OK
To activate or deactivate GPIO pin 3 (output)
Do as follows:
1. Configure GPIO pin 3 in the web interface to be output.
2. Send the command _ITGPIO=1 (activate) or _ITGPIO=0 (deactivate) to the terminal.
3. You get an OK response when the pin is successfully activated or deactivated.
