Interfaces
The printer has two modes of operation for programming the RFID tags: Direct and Label Formatting
Mode.
The Direct Mode allows the User (Host) to control the reading and writing of the RFID Tag directly.
Each RFID tag is individually processed with status and data responses. This mode contains both a
generic Read/Write Interface or High Level Tag HF or UHF specific interface.
The Label Formatting Mode utilizes the current printer configuration to process all the reads, write, and
exception processing, (for exception processing and fault handeling see the Operator's Manual) for each
tag printed. The specification for the RFID operation is contained in the data fields of a DPL label
format. The label format instructs the printer to write data, read data and update selective fields prior to
printing the label. It supports auto increment and decrement commands (+/-). NOTE: Currently only one
RFID operation per label is allowed.
The RFID Programming Data can be entered in one of two different formats: ASCII and Hexadecimal.
The ASCII format is entered as you would normally see it, i. e 'DATA'. The Hexadecimal format is
entered as the hexadecimal equivalent of the ASCII, i.e DATA becomes '44415441'. When entering byte
counts you must take into account the data format you are entering it in. For ASCII mode 'DATA' has a
byte count of 4. For hexadecimal mode '44415441' has a byte count of 8.
