ACK NAK Timeout 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 z
eroes to yield two digits. For example: 0 = 00, 5 = 05, 20 = 20, etc.
3. Go to page 30 and 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 D, Keypad, that represent 
the duration which was determined in the steps above. You will hear a two-beep indica-
tion after the last character.
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 begin-
ning.
6. Scan the ENTER/EXIT PROGRAMMING MODE barcode to exit Programming 
Mode.
This completes the procedure. See Table 27 for some examples of how to set this feature.
