  help. with putting lights on and off

all of a sudden my  ms13a s don't work right..  they are set properly
but do not trigger the lights that are plugged into plm01s
If I use the computer program and send the signal the lights go on and
off. If I use a remote control panel like  hr12a that doesn't work
either.
Strange

How do I fix this
