If the COM port tests correctly and you can not control any modules,
unplug the Serial Interface module from the wall outlet and try running
the Home Director program again.

Be aware that voltage distribution in homes is split from the 220 volt
power input line. There are two separate 110 volt power lines used in
the house. When a signal is sent to a device module, the signal could
travel from one 110 volt line, out to the power transformer, then back to
the other 110 volt line. If this distance is too long, you might experience
intermittent problems. Try plugging the device module in another outlet
socket in the same room.
Ÿ
If you suspect a software problem, exit all other software programs and
try running the Home Director program again. Conflicts may exist
between Home Director and another program. Start the other programs
one at a time to determine which program is causing the conflict.
Ÿ
If you need to reinstall the Home Director software, first backup all the
.HOM files.
