STX/ETX
Label transmissions can be optionally "framed" by STX (Start Transmis-
sion) and ETX (End Transmission) commands. The BCD value represent-
ing any ASCII character shown in the table on the following page is
selectable, except for the following reserved ASCII characters: ack, nak, B,
D, E, R, ~ and del.
To set STX, follow these steps:
1. Determine your requirement for STX character(s), then
consult the ASCII chart shown on the next page to identify
the corresponding BCD value for the desired ASCII
character(s).
2. Scan the SET label.
3. Scan the SET STX label on this page.
4. Scan the digits on the following pages that correspond to the
required BCD value you determined from step one. A
"forced entry" of three digits is required to set the value, so it
will be necessary to preface the digits with a leading zero as
shown in the ASCII table.
NOTE
If you make a mistake, or lose your place while setting this option,
scan the “end” label to exit Programming Mode. The scanner will
sound a rejection tone (a “good beep” followed by a low “bad
beep”) to indicate that programming was incomplete, and the
setting will remain as it was before entering Programming Mode.
5. Scan END.
To set ETX, follow steps one through five above, substituting ETX for STX
at all steps.
