EAN.UCC Composites (GS1 DataBar, GS1‑128, 2D portion of UPC composite) | N/A | Native mode transmission. Note: UPC portion of composite is transmitted using UPC rules. |
| 0 | Standard data packet. | |
| 1 | Data packet containing the data following an encoded symbol separator character. | |
| 2 | Data packet containing the data following an escape mechanism character. The data packet does not support the ECI protocol. | |
| 3 | Data packet containing the data following an escape mechanism character. The data packet supports the ECI protocol. | |
| 1 | Data packet is a GS1-128 symbol (that is, data is preceded with ]JC1). | |
| PDF417 | 0 | Reader set to conform to protocol defined in 1994 PDF417 symbology specifications. Note
When this option is transmitted, the receiver cannot reliably determine whether ECIs have been invoked or whether data byte 92DEC has been doubled in transmission. |
| 1 | Reader set to follow the ECI protocol (Extended Channel Interpretation). All data characters 92DEC are doubled. | |
| 2 | Reader set for Basic Channel operation (no escape character transmission protocol). Data characters 92DEC are not doubled. Note
When decoders are set to this mode, unbuffered Macro symbols and symbols requiring the decoder to convey ECI escape sequences cannot be transmitted. | |
| 3 | The bar code contains a GS1-128 symbol, and the first codeword is 903-907, 912, 914, 915. | |
| 4 | The bar code contains a GS1-128 symbol, and the first codeword is in the range 908-909. | |
| 5 | The bar code contains a GS1-128 symbol, and the first codeword is in the range 910-911. | |
Example
A PDF417 bar code ABCD, with no transmission protocol enabled, is transmitted as ]L2ABCD. | ||
