Cobalto™  CO5300 Scanner
ACK NAK Timeout Value
This option specifies the amount of time the scanner 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 
le
ading zeroes to yield two digits. For example: 0 = 00, 5 = 05, 20 = 20, etc.
3. Go to 
page 27
 and scan the ENTER/EXIT PROGRAMMING MODE bar code to enter Pro-
gramming Mode.
4. Scan the bar code: 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 w
ill hear a two-beep indication 
after the last character.
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 begin-
ning.
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 feature.
