Select the 1-byte, 3-byte, or 13-byte bar code if the first bar code is lost after bootup. The 1-byte bar code consists of one NULL character, 3-byte bar code consists of three NULL characters, and the 13-byte bar code consists of 13 NULL characters. Depending on the bar code type (1-byte, 3-byte, or 13-byte), the scanner sends the bar code data during the bootup process.
