If desired, use this command to designate an event script (
X3%
.evt) to be used to track and
react to hardware happenings and MLC/ IRCM/SCP button presses.
X3%
= event number (0 - 99). The default
value of
X3%
after a system reset is 255.

period from 0 to 255 in 20 ms increments. X21&
is optional: if it is not set, it defaults
to 100 (2 seconds) and is not shown in the command’s response. If
X21&

This command is optional. You do not have to use this command to set up the MLC. By default during confi guration, the confi guration software associates the main event script
fi le (0.EVT) with hardware events and button presses. Once that event fi le has been compiled, it is capable of receiving information from the MLC’s register that tracks hardware actions and button presses. In response to a detected button press or other hardware happening, the event script can then tell the MLC to change relays, issue commands, or make some other change. You would use this command only to associate a different event script fi le with tracking and responding to hardware/button actions.
