Formatter
The formatter handles any reader specific parsing that needs to be done to a raw message coming into (using the decode method) or going out of the reader (using the encode method). For an example, see Formatter.
Handler Method
- A method within a reader's project that handles a specific command for a reader. For example if a Rifidi Symbol reader receives a
Set System ParameterCommand, the following method handles the logic for that command:
public CommandObject setSystemParameter(CommandObject arg, AbstractReaderSharedResources asr) {
byte[] setSystemParam = { 0x04, 0x06, 0x27, 0x00 };
arg.getReturnValue().add(setSystemParam);
return arg;
}Radio
The radio is the interface between the antennas and the TagMemory.
Tag Memory
The tag memory is the structure that holds tags in a specific reader. Each kind of reader should have its own TagMemory.
GPIO
GPIO (General Purpose input/output) is used to interface the reader with other PLC devices such as Light Stacks and Photo eyes.
