Hands-Free Decode Session Timeout

Parameter #
400
 (SSI # F0 90)
This parameter is the hands-free compliment to the Decode Session Timeout. It configures the minimum and maximum decode processing time during a hands-free scan attempt. It only applies to the hands-free trigger mode or when a scanner is placed in the gooseneck stand.
The range for this parameter is
2-255
 with a default value of
15
.
The minimum decode processing time is defined as the time in which the scanner stops decoding when an object is removed or left stationary in the imaging field of view.
The maximum decode processing time is defined as the time in which the scanner stops decoding when an object remains in or is moving in the field of view.
Both the maximum and minimum times are configured using a single setting. The relationship of this setting is as follows:
Setting Value1
Minimum Time
Maximum Time
X < 25
250 ms
2.5 seconds
X >= 25
X * 10 ms
X * 100 ms
For example, a value of 100 causes the scanner to turn off for approximately 1 second after an object is removed from the field of view or 10 seconds while an object is in the field of view moving.
The default value of the setting is
15
, which results in a minimum time of
250 ms
 and a maximum time of
2.5 sec
.
Adjust this setting based on your requirements. For example, this parameter should be set to a value where the maximum time is above the PDF prioritization timeout value when the scanner uses PDF prioritization .
1 value must be three digits.
