4.1.6 Analog/Digital input signals
This section allows the analog and digital control of the adaptive lens through external
signals.
When the adaptive lens is disabled,
Display the Input State
shows the current state of
the input signals (pin 4 and 11 of the Hirose connector). In particular:
• Display the Input State: 0 if both the signals are in a LOW state;
• Display the Input State: 1 if A/D_IN_0 pin is HIGH and A/D_IN_1 pin is LOW;
• Display the Input State: 2 if A/D_IN_0 pin is LOW and A/D_IN_1 pin is HIGH;
• Display the Input State: 3 if both the signals are in a HIGH state.
When the adaptive lens in enabled (see section 13.2) the analog/digital control of the
lens is allowed via an external signal. To do this, the
Input Control Enable
button must
be enabled: when on, the button will turn green.
Two different control modes are possible:
• Driving the lens through an external analog signal (see section 11.6 for electrical
specifications) when the
Enable Analog Input Control
button is clicked.
• Driving the lens through two separate digital signals MOVE and DIR (see section 11.7
for electrical specifications) when the
Enable Digital Input Control
button is clicked.
Please note that the
Enable Analog Input Control
and
Enable Digital Input Control
buttons are ONLY sensitive IF the
Input Control Enable
button is set to the ON position
and the adaptive lens is turned ON.
When using an external driving input signal the
Display the Input State
text will show
the actual state:
• 0
→
the external control isn’t active;
• CONTROL: START
→
the external control is active, but neither the analog nor the
digital control has been selected;
• ANALOG CONTROL: ON
→
the external control is active: the lens is now driven by an
analog input signal;
• DIGITAL CONTROL: ON
→
the external control is active: the lens is now driven by two
digital input signals.
