Code 39 Buffering

While there is data in the transmission buffer, deleting Code 39 buffering
capability via the parameter menu is not allowed.

To allow disabling of Code 39 buffering, first force the buffer transmission (see

Transmit Buffer on page 6-27

) or clear the buffer.

Buffer Data

To buffer data, Code 39 buffering must be enabled, and a symbol must be read
with a space immediately following the start pattern.

Unless symbol overflows the transmission buffer, unit gives hi/lo beep to

indicate successful decode and buffering. See

Overfilling Transmission

Buffer on page 6-27

.

Unit adds the message, excluding the leading space to the transmission

buffer.

No transmission will occur.

Clear Transmission Buffer

To clear the transmission buffer, read a symbol which contains only a start

character, a dash (minus), and a stop character.

Unit issues a short hi/lo/hi beep to signal that the transmission buffer has

been erased, and no transmission has occurred.

Unit erases the transmission buffer.

No transmission will occur.
