5.1.2 Description of the AGC (Automatic Gain Control) anti-disturbance function
The anti-disturbance function is based on the different characteristics of the activation and deactivation signal for
environmental optical disturbances which typically have a dynamic lens.
The function should be activated in the application every time there are significant optical disturbances, which are
indicated in the TXs, when they are in stand by mode, by the red LED flashing every 4 seconds (OP32 and E83MC) and
in the E83RX receiver with the green "on" LED signal (when the TX is not activated).
The function allows the equipment to automatically reduce the sensitivity of the incoming optical signals on the basis of
the intensity of the disturbances, In this way the equipment remains insensitive to the disturbance but is still able to
receive useful activation and deactivation signals.
It is still true, however, that when this function is enabled the optical activation and deactivation signals must be received
with an intensity that is sufficiently higher than the disturbance signal.
As the receiver can receive activation and deactivation signals from a privileged direction, even if this function is
activated it is still good practice for eventual disturbance sources to be screened in this direction in the probe operating
zone.
