INFRARED (IR) OBJECT SENSOR
An infrared (IR) device located behind the window initiates the scanning process.
The IR sensor is active as long as power is applied to the unit. When the IR
sensor detects an object, the green LED will flash. When the laser decodes a
bar code, the scanner transmits the data to the host system and emits a beep to
show that decoding is complete. The IR sensor range can be programmed for
two ranges.
Short Range Activation
The IR signal initiates the scan process if it senses an object anywhere from the
face of the window out to approximately 4" to 7".
Long Range Activation
The IR signal initiates the scan process if it senses an object anywhere from the
face of the window out to approximately 9" to 13".
If the object is removed from the field during the scanning process, the laser
turns off and the scanner re-enters "standby" mode. However, if the object stays
in the field, the laser remains on for up to 2.5 seconds trying to detect another
bar code. If the scanner does not detect a bar code, the scanner re-enters
"standby" mode. To reactivate the scanning sequence, remove the object and
present another.
If the same symbol stays in the field after a successful scan, the laser stays on
for approximately 7.5 seconds and then turns off. This prevents unintentional
reads of the same bar code. To read the same symbol more than once, remove
the object from the scan field for approximately 1 second and then present the
symbol again.
