Set the event number (

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.
X21&
= firmware’s event status polling
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&
is set to 0,
the firmware does not poll for event status.

“Hooking” an event involves associating the event with a specific button so that event will be automatically executed
when the designated button is pressed.
N
The MLC's firmware checks (polls) the status of event scripts on a regular basis. Variable
X21&
represents the length of
time between event status checks.
N
This command is optional. You do not have to use this command to set up the MLC. By default, during configuration, the configuration software associates the main event
script file (0.EVT) with hardware events and button presses. Once that event file 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 file with tracking and responding to hardware/button actions.
