ACK NAK Tim eout Value

This option specifies the amount of time the reader waits for an ACK character from the

host following label transmission. The selectable timeout range is 200 milliseconds to

15,000ms (15 seconds) in 200ms increments. A selection of 0 disables the timeout.

To set this value:

1. Determine the desired setting in milliseconds.
2. Divide the desired setting by 200 (setting is in 200ms increments). Pad the result with
leading zeroes to yield two digits. For example: 0 = 00, 5 = 05, 20 = 20, etc.
3. Scan the ENTER/EXIT PROGRAMMING MODE barcode to enter Programming
Mode.
4. Scan the barcode: SELECT ACK NAK TIMEOUT VALUE SETTING.
5. Scan the appropriate two digits from the keypad in Appendix E, Keypad, that represent
the duration which was determined in the steps above. You will hear a two-beep indica-
tion after the last character.
6. Scan the ENTER/EXIT PROGRAMMING MODE barcode to exit Programming
Mode.

This completes the procedure. See Table 10 for some examples of how to set this feature.

NOTE
If you make a mistake before the last character, scan the CANCEL barcode to
abort and not save the entry string. You can then start again at the beginning.
