Beeper Duration
– Good Read
The beeper duration codes modify the length of the beep the imager emits on a good read.
Default = Normal.
LED
– Good Read
The LED indicator can be programmed On or Off in response to a good read
Default = Normal.
LED Good Read Polarity
LED Good Read Polarity sets the idle and active states of the LED signal. When set to Active
High, the LEDs turn on when the signal shifts from low to high. When set to Active Low, the
LEDs turn on when the signal shifts from high to low.
If the LED is enabled for a good read (see LED
– Good Read), the polarity change takes effect
after the next successful decode or a power cycle. If the LED is disabled, a polarity change
only takes effect after a power cycle. Default = Active Low.
Note:
LED Good Read Polarity sets the LED signal voltage level to either high (Active Low)
or low (Active High). This will affect LED-Good Read setting. If the LED has been disabled,
make sure it is not turned on accidentally by a polarity change.
