5 Reading and writing RFID data using EasyPlug
5.1 Design an EASYPLUG job
5.1.1 The Basics
There are several specialized RFID commands and some extended commands. Some of these commands are
mandatory and some are optional depending on your application. (For example: the #IM command is extended with
antenna offset. This is mandatory information, because a non-zero offset indicates a RFID job.)
Like every EasyPlug job a RFID jobs needs at least a
1) #IM command: defining material parameters and RFID processing parameters (chip type, antenna offset,
optional chip protection)
2) #ER / #Q sequence with contains the layout data and the RFID operations (and optional definitions of
variables for data handling)
Set the RFID parameters in #IM command based on settings you identified in a material setup phase.
Note: the power level setting can’t be controlled using the #IM command. It’s accessible only via the printer menu.
If there is a need to bind the power level setting directly into an EasyPlug job this can be done using the change
system parameter command #PC (#PC5202/<Power level setting>).
5.1.2 Concepts of data handling
Resulting from the continuous enhancement of RFID functionality and improvement of RFID integration with regular
printing functionality there are two different approaches to perform RFID read and write operations have been
created.
1) the legacy EasyPlug commands
2) the RFID parts of the mechanism for variable data handling
Note: Using approach 2) based on the variable data handling is the preferred (because more flexible and powerful)
way to design RFID jobs.
5.1.3 Operation / EasyPlug command matrix
The following matrix shows which EasyPlug commands may be used for specific operations to be performed.
Commands which must be used in sequence are listed with a plus sign (+), alternative commands are separated by
lines.
Please note: the commands are not listed with complete syntax – only most important RFID specific parameters
are shown.
