Chapter 2. Commands
2.1
Introduction
If a PC is connected to the interface, the transmitted application and identification
codes can be stored, converted to other formats, displayed on the PC monitor or
transferred to other equipment. In addition the PC can control the operation of the
TIRIS reader by sending special command characters to it. All the commands that
can be sent from the PC to the TIRIS reader are described in the following sections.
The TIRIS reader accepts both upper and lower case command characters. In order
to provide a uniform style, all examples we have given use upper-case command
character.
2.2
Reader Mode Commands
All TIRIS transponder types fall into one of two groups of transponders: Multipage
Transponders (MPTs) and 64-bit transponders (ROs and R/Ws). Since both of these
transponder groups need different protocols, the TIRIS reader must be able to oper-
ate in two different modes.
2.2.1
64-bit Transponder Mode or K0 Mode
The commands (and responses) that can be used with 64-bit transponders in the K0
mode are described in section 2.4.
2.2.2
Multipage Transponder Mode or K1 Mode
The commands (and their responses) that can be used with multipage transponders
in the K1 mode are described in section 2.5.
2.3
General Commands
The commands that can be used in both modes (K0 and K1) are described in this
section (2.3.1 to 2.3.8) these commands are listed in Table 1.
Note:
The GATE mode for multipage transponders is not supported in K1
mode.
