RS-232 Features

Product Reference Guide 5-81

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 rep-

resent the hex designation for the desired character. A table contain-

ing 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 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 corre-

sponding hex value).

4. The scanner will automatically exit Programming Mode when the

appropriate amount of digits/characters have been scanned.

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.
