Reading Parameters
Double Read Timeout
Double Read Timeout prevents a double read of the same label by setting the minimum time
allowed between reads of labels of the same symbology and data. If the unit reads a label and
sees the same label again within the specified timeout, the second read is ignored. Double Read
Timeout does not apply to scan modes that require a trigger pull for each label read.
Follow these instructions to set this feature:
1. Determine the desired setting in milliseconds.
2. Divide the desired setting by 10 (setting is in 10ms increments). Pad the result with lead-
ing zeroes to yield three digits. For example: 0 = 000, 5 = 005, 20 = 020, etc.
3. Go to
page 74 and scan the ENTER/EXIT PROGRAMMING MODE bar code to enter
Programming Mode.
4. Scan the bar code: SET DOUBLE READ TIMEOUT SETTING.
5. Scan the appropriate three alphanumeric characters from the keypad in
Appendix E, Keypad
representing the duration which was determined in the steps above. You will hear a two-
beep indication after the last character
.
If you make a mistake before the last character, scan the CANCEL bar code
to abort and not save the entry string. You can then start again at the
beginning.
6. Scan the ENTER/EXIT PROGRAMMING MODE bar code to exit Programming
Mode.
This completes the procedure. See
Table 35 for some examples of how to set this feature.
