GPIO
Settings under GPIO tab in www configuration enable user to configure external
input and output GPIO ports. When switching tab to GPIO current pin states is read
automatically into eight fields in upper section of the webpage. In whole configuration
the following convention is used: the unchecked field represents low state and checked
field represents high state. Successful read of GPIO pins states is indicated by ,,OK''
status. In case of error ,,ERROR!'' is displayed. If pins state update is needed, please click
Refresh button.
To set initial states of output pins use checkboxes 11,12,13 and 14. They are set
when the modem is powered up and when the GPIO configuration is changed and saved.
Section GPIO events allows user to create unlimited number of events on which
the state of output pins will be changed. In order to create a new event, click New button
and then fill out all necessary fields. The identifier is used to distinguish events. It can be
any character string. The event type determines if an event is executed only once (One
time) or with determined frequency (Regular). In case of one time event enter UTC date
and time of the event. Make sure that real time clock is set correctly on the device. In
case of regular event specify time interval between two [consecutive] event executions.
Finally choose pin or pins used for the event and what action should be taken (setting
high state, setting low state or switching states). Let's assume pins 11,13 was selected
