Any time the
RUN_SCRIPT
operation is invoked, the reader will sequence
through a maximum of 10 modem commands as follows:
modem.dio.in.X.script.num_cmds = Q
modem.dio.in.X.script.cmd1 = Z
modem.dio.in.X.script.cmd2 = Z
modem.dio.in.X.script.cmd3 = Z
.
.
.
modem.dio.in.X.script.cmd10 = Z
where:
Q
is the number of commands.
Q
can be
0
to
10
(maximum 10
modem commands).
Z
can be any modem command
An event
event.response.modem_dio_scripts dio_in=*,
cmdnum=*, resp=***
is generated after each modem command.
Digital outputs 3 and 4 can be driven by modem after setting the following:
dio.control.X = modem
Actions that triggered the output can be defined by:
modem.dio.out.X.op = Y
where
Y
can be:
NOOP
(default)
END_OF_ROUND
(generates a pulse at end of each inventory round)
ACTIVE_MODE
(triggers high in active mode)
SCRIPT_RUNNING
(triggers high when digital input io triggered
script is running)
ANTENNA_FAILURE
(triggers high in antenna failure state)
ERROR
(generates a pulse when an error occurs)
WARNING
(generates a pulse when an warning occurs)
All output (level/pulse) polarity is defined by:
modem.dio.out.X.polarity = Z
where
Z
can be:
POSITIVE
(default)
NEGATIVE
All pulse width (in µSec) is defined by:
modem.dio.out.X.pulse_width
–(default 100 µSec)
