To set an action to be performed when an active input signal appears it is required to specify the operation
algorithm for an input. The signal, coming to input, is a signal of at least 1 second duration.
The input operation algorithm (see 4.1) is set in the tab
Settings
Advanced
GPIO
of the ATM Control
utility.

* if similar code of an algorithm is assigned for two pins at once, this algorithm will be relevant only for the
GPIO1 operation.
** The pulse counter is active only when the ADC mode is disabled. It has the
Minimum pulse width
, ms,
setting corresponding to the minimum period time during which the GPIO active level must be supported to de-
tect the pulse by the modem.
The modem is fitted with the input pull-up to supply voltage. By default, the pull-up is disabled and the input
is pulled down to the negative supply voltage
(GND)
via the 47 k
Ω resistor. When the pull-up is enabled, the
input is pulled up to the U
in
power supply voltage (MicroFit 4 connector) via the 10 kΩ resistor.
The encapsulation mode has an option of pin state automatic sending to the selected server (see section
). Each server requiring start-
ing ID must have respective option "Add ID" enabled via ATM Control application (
fied: Receiving server message or sending of the starting ID.
). Each pin has its own server selected in the ATM Control utility. And it can be one and
the same server.
The change in state for a digital pin is considered to be a change for
