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 leading zeros to yield three digits. For example:
0 =
000, 5 = 005, 20 = 020, etc.
3. Go to page 62 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 alphanumeri
c
characters from the keypad in
Appendix D, 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 Program-
ming Mode.
See Table 35 for some examples of how to set this feature.
