Buffer Data

To buffer data, Code 39 buffering must be enabled and a Code 39 symbol must

be read with a space immediately following the start pattern.

! Unless the data overflows the transmission buffer, the decoder

issues a lo/hi beep to indicate successful decode and buffering.

(For overflow conditions, see Overfilling Transmission Buffer.)

! The decoder adds the decoded data excluding the leading space to

the transmission buffer.

! No transmission occurs.

Clear Transmission Buffer

To clear the transmission buffer, scan the Clear Buffer bar code below, which

contains only a start character, a dash (minus), and a stop character.

! The decoder issues a short hi/lo/hi beep.

! The decoder erases the transmission buffer.

! No transmission occurs.

Note: The Clear Buffer contains only the dash (minus) character. In order to

scan this command, be sure Code 39 length is set to include length 1.

1. Scan the Transmit Buffer bar code below. Only a start character, a

plus (+), and a stop character.

! The decoder transmits and clears the buffer.

! The decoder issues a Lo/Hi beep.
