ACK NAK Retry Count
This feature specifies the number of times the reader retries a label transmission due to
a retry condition. The selectable range is from 1 to 254 retries. A selection of 0 disables
the count, and a selection of 255 specifies unlimited retries.
To set this feature:
1. Determine the desired setting.
2. Pad the number with leading zeroes to yield three digits. For example: 0 = 000, 5 =
005, 20 = 020, etc.
3. Scan the ENTER/EXIT PROGRAMMING MODE bar code to enter Programming
Mode.
4. Scan the bar code: SELECT ACK NAK RETRY COUNT SETTING.
5. Scan the appropriate three digits from the keypad in
Appendix E
, that represent
the number which was determined in the steps above. You will hear a two-beep
indication after the last character.
6. Scan the ENTER/EXIT PROGRAMMING MODE bar code to exit Programming Mode.
This completes the procedure. See the table below for examples of how to set this fea -
ture.
Table 7 - ACK NAK Retry Count Setting Examples
NOTE: 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.
