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 66.
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 is left 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
252 > X >= 25
X * 10 ms
X * 100 ms
X= 252
10 seconds
25 seconds
X= 253
15 seconds
25 seconds
X= 254
20 seconds
25 seconds
X= 255
25 seconds
25 seconds
For example, a setting value of 100 results in the scanner turning off 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 seconds.
The default value of the setting is 66, which results in a minimum time of 660 ms and a maximum time of 6.6 seconds.
Adjust this setting based on your requirements. For example, when doing PDF prioritization, this parameter should be set to a value where the maximum time is above the PDF prioritization timeout.
To set a three digit value scan the following bar code, and then scan three bar codes from Numeric Barcodes. Enter a leading zero for single-digit numbers. To correct an error or change a selection, scan Cancel.
