RS-232 NAK Character
This feature specifies which ASCII character will be used as a NAK character.
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.
To specify the RS-232 NAK Character:
1. Scan the Enter/Exit Progr
amming Mode bar code.
2. Scan the bar code, SET RS-232 NAK Chara
cter 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 Alpha-Numeric Keypad in Appendix C
that represent the hex designation for the
desired character. A table con-
taining the ASCII Characte
r Set and their corresponding Hex Values 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.
