5.6 READING PARAMETERS

5.6.1 Trigger Signal

This mode determines how the reading phase is controlled when the hardware trigger

operating mode is selected:

 trigger active level: the reader goes ON when the trigger is pressed and goes OFF

when it is released

 trigger active pulse: the reader goes ON at the first trigger press and goes OFF

only at a second press

5.6.2 Trigger Click

When enabled, it activates a "click" sound upon each trigger pressure.

5.6.3 Trigger-Off Timeout

When this timeout is selected, the reader turns OFF automatically after the desired

period of time.

5.6.4 Reads per Cycle

In general, a reading cycle corresponds to the ON + OFF times of a device.

The resulting effects of this parameter on code reading depend on other related

configuration conditions. Here are the definitions of ON and OFF times.

 For readers using the software trigger parameter (FLASH MODE), a reading cycle

corresponds to the

flash on

flash off

times. Code reading takes place during the

flash on

time.

 For readers using the

hardware trigger

parameter, a reading cycle corresponds

to a trigger press (ON) + one of the following OFF events:

trigger release (for

trigger active level

)

a second trigger press (for

trigger active pulse

)

trigger-off timeout

(see section 5.6.3).

When one read per cycle is selected, the device decodes only one code during the ON

period and immediately turns the reader OFF. It is only possible to read another code

when the next ON time occurs.
