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.
