Code 39 Buffering
While there is data in the transmission buffer, deleting Code 39 buffering
capability via the parameter menu is not allowed. The buffer will hold 250
bytes of information.
To allow disabling of Code 39 buffering, first force the buffer transmission (see
Transmit Buffer) 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.
• 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.
