64-Bit Transponder - K0 Mode
The commands that can be used in the K0 mode for use with 64-bit transponders are
described in this section (2.4.1 to 2.4.9) these commands are listed in Table 8.
2.4.1
EXECUTE Command
The ASCII character X switches the TIRIS reader to a single readout mode and trig-
gers a single readout sequence. After the readout the TIRIS reader is in an idle loop,
waiting for the next command.
When an identification number is received and it is a valid number, the TIRIS reader
transmits the ASCII character X, the transponder type character, space, 4-digit
application code, space, 16-digit identification code, carriage return and line
feed to the PC. If the system does not read an identification number, the ASCII char-
acter X (XI if the identification was not valid), carriage return and line feed are trans-
mitted.

2.4.2
GATE Mode
In the GATE mode each correct identification number is compared with the identifi-
cations stored in the identification memory. If the identification number is new, it is
then stored in the identification memory.
The ASCII character G activates a continuous readout mode. The TIRIS reader con-
firms with the ASCII character G, carriage return and line feed. Each time that a
new identification is stored in the identification memory the ASCII character G, the
transponder type character, space, the actual memory count number, space,
application code, space, identification code, carriage return and line feed are
transmitted via the interface.
