• Code 93 is similar in character set to Code 39. See Appendix F; Code 93
for more information. Code 93 is not a commonly used bar code symbology.
Preamble
Preambles are user-defined data that is attached to the beginning of data (bar
code or keyed) that is transmitted to the host by the RF Terminal. For example,
if you set a preamble of @@ and scanned bar code data of 12345, @@12345
would be transmitted to the host.
• By default, the RF Terminal has no preambles configured. Preambles can
contain up to 15 characters scanned from the bar coded FULL ASCII Menu.
To set a preamble:
1. Scan the Preamble bar code or select Preamble from the
keypad menu.
2. Scan the desired characters (up to 15) from the FULL ASCII
Menu.
3. Scan the SET bar code, or if using the keypad, press
ENTER.
4. To clear the Preamble and return to the default (no
Preambles defined), scan CLEAR at step #2, and then
continue with your setup.
• You can use the Preamble to trim characters from the data you are
entering into the RF Terminal. You can trim from 1-15 characters
from the data by creating a preamble of:
~x
where ~ is ASCII 126 and x is a single hex digit 1-F (correspon-ding
to 1-15). Data that is shorter than the trim amount is transmitted
without trimming. Preambles trim characters from the front of the
data. Here are some examples:
