Initiating the System
The SAT RS-485 communication loop wires are connected to the
“R” and “T” and shield terminals on the satellite controllers using
¼-inch Sta-Con connectors. Make sure the polarity is correct. That
is to say, the wire connected to the “R” and “T” terminal on the
WCCIII-MCD2 must be connected to the “R” and “T” terminal
on the satellite controllers. If the “R” and “T” and shield wires
are crossed, the WCC III system will not communicate. The shield
should be connected together when the cable is cut in order to
terminate the wires at the satellite controller. The communication
loop wire from the WCCIII-MCD2 is connected to one of the “R”
and one of the “T” terminals on the satellite controller, which is
physically located nearest the WCCIII-MCD2. The other “R”
and “T” terminals located on the satellite controller can be used
to extend the two-wire loop to the next satellite controller, or the
wires can branch off of a two-wire loop running through the center
of a building.
NOTE: The shield wire must be connected at each and every
Satellite Controller, also.
After the satellite controllers have been installed and powered
up, the WCCIII-MCD2 set up, and the 2-wire communications
line connected between all of the satellite controllers and also
connected to the WCCIII-MCD2, then the WCC III data fi les need
to be loaded into the WCC III - MCD. This is best accomplished by
using the WCC “mcd-menu” batch fi le, remotely with the Webmin
program, or by directly using the Linux command prompt on the
WCC III-MCD2 VGA monitor/USB Keyboard connections.
NOTE: When converting the WCC II data fi les to WCC III
type data fi les, the WCC II data fi les have to be converted
to the new WCC III type data fi les using the WCCUtilities.
exe program. Then these new WCC III data fi les need to be
installed on the WCCIII-MCD2. This is best accomplished
by using the WCC “mcd-menu” batch fi le, remotely with the
Webmin program, or by directly using the Linux command
prompt on the WCCIII-MCD2.
The WCC III–MCD2 has two solid state hard drives, one that
has the Linux operating system along with the backtask program,
and one that has the daily/monthly WCC III backup data fi les
on it. A USB thumb drive can be used to shuffl e the data in and
out of the WCC III–MCD2. Another program called “Webmin”
is primarily used to administer the more advanced setup features
on the WCCIII–MCD2. This “Webmin” program requires an
internet browser, such as Mozilla, or Microsoft Internet Explorer
to function.
This “Webmin” program can be used over the internet/intranet or
locally with a network crossover cable. The “Webmin” program is
pre-installed on the Linux OS hard drive on the WCCIII-MCD2.
There are three password levels for the “Webmin” program, one
for the simple user, one for the contractor level, and one for the
WattMaster factory administrator.
WCCIII-MCD2 System Files
The Backtask program on the WCCIII-MCD2 is stored on the
solid state hard disk, so after boot-up, the system start up fi les will
cause the Backtask Program to run.
CAUTION: The WCCIII-MCD2 will not communicate
with the satellite controllers while it is going through the “re-
boot” process. If the satellite controllers do not communicate
with the WCCIII-MCD2 for approximately three minutes,
they will go into local set. The time it takes for the system to
“re-boot” should not cause the satellite controllers to go into
local set. The hard disk can hold a vast amount of data which
can accidentally be erased or lost due to system malfunction,
operator error, etc. Therefore it is extremely important to
make a back-up copy of the data on the hard disk. As you
program a system to control a building, information is written
on the disks. Therefore, back-up copies of programming data
fi les on the hard disk should be made after the system has
been programmed to control the building. This can be done
remotely through the WCC Utility program.
