1.2 ANALOG INPUTS
The device has four analog inputs – IN4 (A4), IN5 (A5), IN6 (A6), and IN7 (A7), which support
several operation modes for connecting the corresponding sensors.
‘Discrete mode’
shows the input state, when input voltage more than 6V – the input is activated
(state “1”), else – the input is deactivated (state “0”). The state of the discrete inputs is transmitted
bitwise in the Wialon`s "pin" parameter. In binary form, each bit of the "pin" parameter reflects the
status of the corresponding input. For example, a value of 32 in decimal means that IN_5 is activated
and the others are deactivated.
U0
ADC mode
– sensors with an analog outputs can be connected (temperature sensors, analogue
FLSs, regular FLSs, and ignition). Up to four sensors can be connected at the same time.
Analog sensors are connected to the analogue inputs IN4 (A4), IN5 (A5), IN6 (A6), IN7 (A7).
The bit width of the ADC input is 12 bits. Voltage measurement range: 0-33 V.
In Wialon system, analog state is contained in parameters “volt_4 - volt_7”.
Ignition mode
– the mode is selected when the ignition is connected to the selected input. The
input configured for this mode works on the principle of discrete and its state is duplicated in a separate
parameter "v_in".
Call button mode
– input works as discrete. After activation of the input (including short-term)
will be made to dial the numbers listed in the device settings, in order of priority (from 1 to 5). In the
"phone numbers" web Configurator it is possible to adjust the sensitivity of the microphone and the
volume level of the speakers.
