Chapter 2. Commands
2.5.2
LINE Function
If the command L is immediately followed by a page number (in the range 01 to 11)
the system continuously reads the specified page as described in section 2.5.2.1. If
the command L is immediately followed by the letter M the system is switched into
Multiplexer mode as described in section 2.5.2.2.
2.5.2.1
Line Function
The ASCII character L and an additional two digit page specification (01 to 11
hex
)
switch the TIRIS reader into a special continuous readout mode.
The TIRIS reader acknowledges the command by returning the character L. When
the page number is received by the TIRIS reader it is acknowledged by carriage re-
turn and line feed.
In this mode each correct identification number is transferred directly to the interface
without any buffer comparison. In addition the ASCII character L, the antenna num-
ber, read status information (only for MPT) and the transponder type are trans-
mitted in front of each identification number. If no identification is received or if the
identification is not valid, the ASCII character L together with the number of the con-
nected antenna and an optional I, carriage return and line feed will be transmitted
to the PC.
