Settings of the outputs are made in the “Output lines” tab of the NTC Configurator program.
One of the outputs can be used for control of sound signal emitting with help of the buzzer, for warning or EcoDriving
function indication and for reminding about TM-key attaching (or RFID card).
Buzzers may be different in operating voltage, in the presence or absence of a built-in generator. A buzzer with a
built-in generator can emit a sound signal independently when a constant supply voltage is applied.
In order buzzer operates without built-in generator, supply voltage modulation is required.
Buzzer without built-in generator can be connected only to OUT1, because only this line has opportunity to modulate
the control signal for the buzzer.
Buzzer with built-in generator can be connected to any output. Connection diagrams for buzzer with build-in
generator and for buzzer without build-in generator have no difference.

It is possible to connect LED for indication of device operation mode and security mode state.
If the power source is vehicle’s on-board network, the LED must be connected through current-limiting resistor. Such
resistor is already installed inside the lamp in the automotive LED lamps. It is only necessary to select the LED lamp under
the desired voltage of the on-board vehicle network.

When security functions are used, it is possible to control the car siren. If the siren has a separate input, controlled
by “-”, then the output of the terminal can be connected to this input directly.
