RS-232 NAK Character
This feature specifies which ASCII character will be used as a NAK char-
acter.
To specify the RS-232 NAK Character:
1. Scan the SWITCH 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 keypad in Appendix C that
represent the hex designation for the desired character. A table
containing the ASCII Character 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 dig-
its 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
appropriate amount of digits/characters have been scanned.
SET RS-232 NAK Character
NOTE
DO NOT set this feature to use previously defined characters 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 Number
of Data Bits, is set to 7 data bits.
