ACK Character 
 
This setting specifies an ASCII character to be used as the ACK character. Selections: a 
character from NUL (0x00) to DEL (0x7F). 
 
 
NOTE 
The ACK Character must be different from the NAK Character and must not 
contain reserved characters (see Appendix D). Setting to previously defin
ed 
characters such as XON, XOFF, or host commands conflicts with normal 
operation of these characters. 8-bit data is not recognized when the option 
Data Bits has been set as 7 Data Bits. 
 
To set this feature: 
1.  Determine the desired character. 
2.  Use the Chart in Appendix C to find the hex equivalent
 for the desired character. 
3. Go to page  39  and scan the ENTER/EX
IT PROGRAMMING MODE to enter 
Programming Mode. 
4.  Scan the barcode: SELECT ACK CHARACTER. 
5.  Scan the two hex equivalent characters
 from the keypad in Appendix B that represent the 
desired character in step 1 above. 
6.  Scan the ENTER/EXIT PROGRAMMING MODE barcode to exit Programming Mode. 
 
This completes the procedure.
