RS-232 NAK Character
This feature specifies which ASCII character will be used as a NAK character.
To specify the RS-232 NAK Character:
1. Scan the Enter/Exit Programming Mode bar code.
2. Scan the bar code, SET RS-232 NAK Character below. You’ll need to cover
any unused bar codes on this and the facing page to ensure the scanner
reads only the bar code you intend to scan.
3. Scan the appropriate digits from the the Keypad on page 461 in
Appendix C that represent the hex designation for the desired character. A
table containing the ASCII Character Set and their corresponding Hex Val-
ues is available in the inside back cover of this manual. ASCII parameters
must be input by scanning a pair of hexadecimal digits for the desired
character. For example, if ASCII “A” were the desired NAK character, you
would scan the digits “4”, then “1” (the ASCII corresponding hex value).
4. The scanner will automatically exit Programming Mode when the appro-
priate amount of digits/characters have been scanned.
NOTE
DO NOT set this feature to use previously defined char-
acters such as XON, XOFF or host commands as this will
conflict with normal operation of these characters. 8-bit
data is not recognized when the feature, RS-232 Num
-
ber of Data Bits, is set to 7 data bits.
