^RB

Define EPC Data Structure

Description Use this command to define the structure of EPC data, which can be read from

or written to an RFID transponder. For more information about EPC specifications, refer to the

EPC Global web site. All parameters in this command are persistent and will be used in

subsequent formats if not provided. The values are initially set to the default values.

RFID transponders can have different partitions defined. This command specifies the number

of partitions and how many bits are in each partition.

Format ^RBn,p0,p1,p2, ..., p15

This table identifies the parameters for this format.

Important • This command is not supported by all printers or firmware. See Table 13

on page 287 for the list of printers and firmware with which you can use this command.

Parameters Details

n = total bit size of the

partitions

Specify the number of bits to include in the partitions.

Accepted values: 1 to n, where n is the bit size of the tag.

Default value:

p1 ... p15

partition sizes

Specify the number of bits to include in the individual partitions. The partition

sizes must add up to the bit size specified for the previous parameter. The

largest individual partition size is 64 bits.

Accepted values: 1 to 64

Default value:

Example 1 • The following command specifies that there are 96 bits used with three fields.

Fields 1, 2, and 3 contain 10, 26, and 60 bits, respectively.

^RB96,10,26,60

The ZPL code to encode a tag with this format would look like this:

^RFW,E^FD1000.67108000.1122921504606846976^FS

When the tag is being encoded, the tag stores the data in the following way:

• Field 1 contains

1000. This value is stored in the first 10 bits

• Field 2 contains

67108000. This value is stored in the next 26 bits.

• Field 3 contains

1122921504606846976. This value is stored in the remaining

60 bits.
