WCC III - MCD2 History Information
The WCCIII-MCD2 (WM part # OE405-02) was designed as
a product improvement of the older WCCIII-MCD (WM part #
OE405-01) and as such is a drop-in replacement unit for the older
WCC III-MCD computer product (WM Part # OE405-01). The
original WCCIII-MCD was designed as a product improvement
upgrade for the old WCCII type computer .
The heart of the WCCIII-MCD2 is an industrial-rated single board
computer that is within a custom-designed wrap-around sheet
metal computer enclosure that matches the look of the satellite type
3 controllers, and this makes the new WCCIII-MCD2 about one
quarter the size of the previous WCCIII-MCD. It has completely
quiet operation due to the fact that the new WCCIII-MCD2 is
completely fanless due to far less power requirements of the newer
generation of Intel
TM
processors.
The WCCIII-MCD2 is powered off of a single 24VAC @50VA
transformer (WM part # WP000050) – that is supplied with the
WCCIII-MCD2.
Also the new WCCIII-MCD2 uses a lot less separate individual
components in its construction than the old WCCIII-MCD
computer.
The old WCCIII-MCD used 7 separate cable assemblies to
interconnect the various circuit boards with in the WCCIII-MCD
case to each other. The new WCCIII-MCD2 uses a single cable
assembly called “SBC INTERNAL I/O CABLE” (WM part #
HZ00160) to interconnect the various circuit boards together.
There used to be a separate circuit board on the old WCCIII-MCD
that was used to control the power startup/shut down functions. On
the new WCCIII-MCD2, these power start up/shut down functions
are now handled by the CrystalFontz LCD controller. There was
also a passive backplane board on the old WCCIII-MCD, and this
was eliminated on the WCCIII-MCD2 design. The old WCCIIIMCD case used 17 separate pieces of steel sheet metal in its
design, whereas the new WCCIII-MCD2 has two simple pieces of
lightweight aluminum for its case design.
There are no physical moving parts within the WCCIII-MCD2.
WattMaster uses the start up and shut down operational control
of this new WCCIII-MCD2 design with the addition of a 4 line
by 20 character CrystalFontz LCD controller board. In addition,
WattMaster Controls has developed an additional circuit board
called the MCOMM board, which is a PIC32 based 4 channel –
Isolated RS-485 communication packetizer and unpacketizer for
the WCC III satellite type of communications loop.
The WCCIII-MCD2 will communicate to up to 240 of the
WattMaster Controls SAT 3 series of fi eld programmable
controllers. Also, a very specialized, small and compact power
supply module was designed to supply +12VDC @ 4 Amps
power to the MCOMM board, PCM-9362N CPU board, and the
CrystalFontz LCD controller, and this power supply module is
called “LTM8027 Power Supply Module”.

Main Differences Between MCD and MCD2
NOTE 1
The fi rst generation WCC III - MCD platform was by nature a work in progress, which due to unforeseen circumstances, the following was replaced and/or upgraded
over time: (Also See NOTE 2.)
Conventional spinning Hard Drive – W as replaced by a 4 gig solid state IDE hard Drive.
3 ½ inch Floppy Drive - W as replaced with a 2 by 20 line LCD display.
No data backup drive - W as replaced by a compact fl ash drive with nightly and monthly automatic data backups.
65 W att Power supply - Was Replaced with a 150W power supply. Original Power Supply was not enough.
This fi rst generation WCC III - MCD platform started out as a W indows XP based system, and then over time the fi rst generation WCC III - MCD has been upgraded to
the Linux Ubuntu operating system, which over time became the upgraded WCCIII-MCD. Windows XP operating system required that a keyboard/mouse emulation
box to be attached to the fi rst generation WCC III – MCD, or else certain errors could occur . Windows pretty much requires a Keyboard to function. (Mainly this had
to do with the “Auto-detect” of devices that are connected, and when a keyboard is not detected at some one of sacred fi les would get corrupted, and then cause failure
to boot up issues.) The Windows XP operating system was very susceptible to viruses, and required anti-virus software to be installed, but the antivirus software caused
almost as much problems with continual anti-virus updates, and yearly renewal issues. (The Linux operating system is much less prone to viruses) The Windows XP
operating system was obsoleted by Microsoft, and at this point there is no long term support for this Windows XP operating system anymore.
NOTE 2
The fi rst generation WCCIII-MCD (Referred to in this document as the old WCCIII-MCD) started life out as a Windows XP based system, and over time the fi rst
generation WCC III - MCD has been upgraded to the Linux Ubuntu operating system. At this time the “BackTask” program was written so that it required that it be
running under the Widows operating system, so the fi rst generation WCC III - MCD had the necessary Linux fi les installed so that the “BackTask” program could
be ran under the windows operating system in emulation mode from within the Linux operating system. This emulation mode also used up some 384 meg of main
hard drive space. The new WCCIII-MCD2 has the Linux Ubuntu operating system (V12.04 LTS), but without the windows emulation fi les, because the “Backtask”
program has now been rewritten so that it is running natively in Linux without having to run it in the Linux windows emulation mode.
Before starting the assembling of any WCC III-MCD2, please get the latest and greatest parts lists from Solomon (OE405-02).
All of the parts needed for the building to the required quantities of WCC III-MCD2 should be pulled fi rst, and then the shortages ordered, and then these shortages
should be fi lled before further proceeding in any assembling process.
NOTE 3
There is also a software provision within the WCCIII-MCD2 to control the shutdown of the WCCIII-MCD2 via USB commands that are sent from an APC
UPS (Uninterruptible Power Supply) upon detection of loss of power. When the battery in the UPS drops to 3 minutes of remaining power, the MCD will auto shut
down. A USB cable must be connected between the APC
be made to any of the four USB ports on the WCCIII-MCD2. This USB cable is supplied by APCTM in the box with the UPS.
WattMaster Controls recommends the following USB connected APCTM brand Uninterruptible Power Supplies:
The APC brand UPS must be a minimum of 500VA (300 Watts) and must have a USB connection. A short 1 foot extension cord may also be required to connect the
WCCIII-MCD2’s wall mounted transformer to the UPS in order to utilize all of the other UPS’s power plugs.

System Requirements
Uninterruptable Power Supply
The WCCIII-MCD2 system is designed to automatically restart
after a power failure. However, the industrial computer which
acts as the WCC III-MCD2 Master Communications Device will
not automatically reboot unless the power is shut off cleanly and
then restored cleanly. During most power outages, the incoming
115 AC voltage could have great fl uctuations before the power
fi nally fails. In a like manner, brownouts will usually cause the
industrial computer to “lock-up.” That is to say, the screen will
continue to display on the monitor, but the cursor will not respond
to the keyboard commands. To prevent this “lock-up” issue from
happening to the WCC III-MCD2, an Uninterruptible Power
Supply (UPS) is required on each and every WCCIII-MCD2
computer.
An Uninterruptible Power Supply (UPS) provides emergency
power to keep the WCC III-MCD2 Master Communications
Device (personal computer) on-line for several minutes after a
primary power failure. The UPS regulates the incoming power
to the computer and shuts the power off cleanly several seconds
after the power outage, or brownout. When the primary power
is restored, the UPS brings the WCCIII-MCD2 back on-line
automatically. The WCC III system does not lose any information
since all of the programs and user entered data are stored on either
a disk in the MCD, on fi rmware, or on battery backed memory in
the satellite controllers.
Software Updates
WCC III-MCD2 program updates will be made available using
USB “jump” drives and/or internet downloading.
NOTE: As of September 1, 2009, all WCCIII-MCDs will only
be shipped with the Linux operating system installed. Older
Windows XP-based WCCIII-MCDs should be upgraded for
any future support issues from WattMaster. The Windows
XP operating system is at the end of long term support with
Microsoft. Microsoft’s main issues are with continuous
updates, and the multitude of viruses that are written for
Windows XP are also of concern. The Linux operating system
software on the WCCIII-MCD2 must be maintained and
updated periodically. W attMaster Controls, Inc. can do these
software updates and upgrades remotely via the internet only
if the WCCIII-MCD is connected to the internet. This is why
internet access to the WCCIII-MCD2 is so important. Failure
to keep the operating system updated could result in a WCC
III-MCD2 system malfunction. WattMaster Controls, Inc. is
not responsible for a system failure that is so generated due to
lack of upgrading or updating because the end customer does
not provide a static IP connection for the WCC III - MCD2 to
the internet for W attMaster Controls to connect to.
Basic Operating Conditions MCD2

• If WattMaster Controls factory assistance or
troubleshooting is required for a WCC III system,
a representative from the factory can access the
system with a remote computer and view the same
WCC III Screens as the end user or contractor
in the building. This allows the end user or the

RS-485 Communications Wiring
The WCC III System RS-485
Communications Wiring
The WCCIII-MCD2 can communicate with up to 239 satellite
controllers via a two-wire RS-485 communication loop. On
the bottom side of the WCCIII-MCD2 there are four RS-485
communication loop ports that come as standard. Each one of
these communications loop ports can communicate with up to 60
satellites for a total of 120 satellites.
The two-wire RS-485 communication loop should be stranded 2
wire twisted pair of 18-gauge wire with a shield wire, and it also
must be plenum rated were applicable. The use of stranded wire is
mandatory to ensure a good connection with the ¼ inch Sta-Con
connectors which are used to terminate the wires at the satellite
controllers. The RS-485 communication wire does not have to be
run from each satellite controller back to the WCCIII-MCD2, but
rather the RS-485 communication wire can be “daisy-chained,”
which means that only one twisted pair of wires is connected to
each of the WCCIII-MCD2 communications loops. The maximum
allowable length of wire from the WCCIII-MCD2 to the farthest
satellite is 4000 feet per RS-485 communications loop.
NOTE: A length greater than 4000 feet is allowed under
certain circumstances. Consult the factory for assistance if the
communications loop required for your application will exceed
4000 f eet.
The RS-485 wire specifi cations are generally a stranded 18-
gauge - 2 wire twisted pair with shield. 18-gauge stranded wire is
mandatory to ensure a good connection with the ¼ inch Sta-Con
connectors, which are used to terminate the wires at the WCC IIIMCD2 and at the satellite controllers. The old SAT II Manchester
communications loop was supposed to have used a 2-wire twisted
pair with shield, but this was not used in every installation. This
old SAT II communications loop should not be used for the new
SAT III communications loop. A new RS-485 communications
loop should be ran to each new replacement SAT III controller.
The shield wire must be used on the new SAT III controller, as
it provides a “ground” reference for the RS-485 communication
loop. WattMaster Controls sells two versions of 18-gauge - 2-wire
twisted pair with shield communications wire—(1) WattMaster
part #WR-NL-WR-18 which is marked “Network Loop” with
a red stripe for rapid identifi cation. This connection is intended
to run from the WCC III – MCD2 to the SAT III, SAT 3C/D/F,
SA T3P, and then to the next SA T 3 type controllers. (2) W attMaster
part# WR-LL-WG-18 which is marked “Local Loop” with a green
stripe for rapid identifi cation for the TUC loops that run from the
SAT 3C/D/F controllers out to the TUC controllers. “Wire Nuts”
on the RS-485 communications loop should be avoided at all costs.
As an alternative to the “Wire Nuts”, WattMaster Controls has a
Power and Switchable RS-485 communications board, and the
W attMaster part number is PL102224. This Power and Switchable
RS-485 communications board can be thought of as a 24-VAC
power and communication distribution system for the SAT III
communications loop, and this board will aid in initial startup
and future troubleshooting of the SAT III communications loop.
These boards should be used on a fl oor-by-fl oor basis. This Power
and Switchable RS-485 communications board is also available
in a small metal electrical enclosure. The wire that makes up the
communication loop should be shielded. Shielded cable has an
aluminum jacket over the wires that could act as an “antenna”
to carry away any “stray” electrical signals that could interfere
with the communication process. The shield should be grounded
throughout the SAT Loop.

WCCIII-MCD2 Mounting Requirements
WCCIII-MCD2 Mounting Requirements:
The WCCIII-MCD2 was designed to be wall mounted, and
therefore should be mounted on a wall or in a NEMA 1 rated
electrical enclosure.
The WCCIII-MCD2 should be mounted in an air-conditioned
space (The ambient temperature must be between 50 and 100
°F, and the relative humidity must be kept between 0 and 90%
(non-condensing)). Setting the WCCIII-MCD2 on a desktop is
possible, but not recommended due to top and bottom ventilation
considerations.
Mounting in an NEMA type 1 electrical enclosure is possible
providing that there is enough ventilation and minimum clearance
for ventilation. The height of mounting the WCCIII-MCD2 should
be at eye level or with local codes on compliance with the ADA
act of 1990/2009. A minimum of two inches of clearance should
be maintained all around the WCCIII-MCD2, with the exception
of the bottom side of the WCCIII-MCD2 where four inches of
clearance is required for connector’s clearances.
When mounting the WCCIII-MCD2, proper minimum clearance
distances must be met and must be maintained. Space must be
allowed for proper ventilation. When mounting in an electrical
enclosure, be sure that you would avoid mounting the WCCIIIMCD2 above any heat generating sources such as transformers,
and energized contactors, etc. Some thought must be given to the
possibility of adding ventilation to the NEMA 1 rated enclosure
that the WCCIII-MCD could be mounted in if so mounted.

Pow er Supply Requirements
Power Supply (24VAC) Requirements
The WCCIII-MCD2 should only be powered by a dedicated
wall wort type 120VAC to 24VAC @50VA transformer, and this
transformer should only be used to power up the WCCIII-MCD2.
There should be no other devices/controllers that should be powered
off of this dedicated transformer . WattMaster Controls supplies the
WCCIII-MCD2 with such a transformer (WM Part # WP000050).
There is a modifi ed power cord (WM Part # HZ000161) that is
to be supplied with the WCCIII-MCD2’s transformer. There are
two fork terminals (WM Part # SL18RA6F – Fork Terminal,
#6 screw, 18 to 22 Gage) that are used to connect this modifi ed
cable to the 50VA transformer. The other end of this cable is a 2
position de-pluggable type connector (WM Part # GP000136 TERMINAL PLUG - 2 POSITION DEPLUGGABLE). Again
only the WCCIII-MCD2 should be powered from this dedicated
24VAC@50VA transformer. With the use of screw terminals on
the transformer that WattMaster Controls supplies you can easily
change the length of the power cord to up 100 feet. You must use
a minimum of 18 gauge wire (16 or 14 gage wire would be better)
to accomplish this.
If you choose not use the supplied dedicated wall wort type
120VAC to 24VAC @50VA transformer, then an isolation
transformer must be used. The only other option is to use a separate
dedicated transformer (only connected to the WCCIII-MCD2) that
can be connected to the WCCIII-MCD2 device. This transformer
must have an output that is rated for 24VAC @ 50 VA minimum
with appropriate fusing for its size.
The 24VAC@50VA power transformer for the WCCIII-MCD2 is
to be connected to a dedicated APCTM brand UPS ( Uninterruptible
Power Supply) outlet so that the WCCIII-MCD2 will keep
running during a minor power outage. The Cable/DSL modem/
router should also be plugged in to one of these dedicated UPS
(Uninterruptible Power Supply) outlets. Take note that the UPS
may have several outlets but not all are marked backup power.
Some are surge suppression only . Use the backed up power outlets.
The WCCIII-MCD2 has the ability to monitor power status of
the UPS to control the shutdown of the WCCIII-MCD2 via the
supplied APC USB cable. These commands that are sent from an
TM
APC
brand UPS (Uninterruptible Power Supply) upon detection
of loss of power will alert the WCCIII-MCD2 of power failure
that is then logged to the MCD’s SYSLOG fi le. The MCD will
monitor the UPS until there are 3 minutes of power remaining and
then initiate a shut-down of the WCCIII-MCD2. Upon resumption
of normal power, the WCCIII-MCD2 will power up on its own and
log the event in SYSLOG of the OS.
***WARNING*** If not using the supplied 24 V A C @ 5 0V
transformer, you must observe polarity if this other 24 V A C
transformer is connected to other devices. The use of another
transformer is NOT recommended.

Initiating the System
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
Satelli te Con troller , 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.
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
W attMaster 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 “reboot” 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 copi es 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.
NOTE: When converting the WCC II data fi les to WCC III
type d ata 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.

Input/Output Connections
Various I/O connections tha t are on the
Bottom Side of the WCCIII-MCD2 De vice
24VA C P ow er Connector
A two position de-pluggable connection is provided for power
connection to the WCCIII-MCD2 device. The WCCIII-MCD2 is
powered off of dedicated 120VAC to 24VAC@50VA transformer
that WattMaster Controls supplies with each WCCIII-MCD2
device. The 24VAC power de-pluggable connector is considered
to be “polarized” with a 24VAC side and a GND side. Correct
power polarity must be observed.
RS-485 Connectors
The WCCIII-MCD2 device provides four separate RS-485
connections. Each one of these three position de-pluggable
RS-485 connections are distance rated for up to 4000 feet of
communications loop cable when using approved communications
wire. (WM Part # or WM Part #). This communications cable is
described as 18 gauge single pair twisted, with a shield, and drain
wire. The Drain wire (Shield) must be connected between the
WCCIII-MCD2 device and all of the Satellite controllers.
R & T COMMUNICATIONS LEDs
There are simplistic communication diagnostic LEDs that are
provided next to each one of the RS-485 connectors. The LED
marked “R” stands for “Receive”, and this red LED will fl icker
when data is received from a specifi c satellite controller. The LED
marked “T” stands for “Transmit” and this red LED will LED will
fl icker when data is transmitted by the WCCIII-MCD2 to a specifi c
satellite controller).
10/100 Network ports eth0, and eth1
The main Ethernet port on the WCCIII-MCD2 is named and
labeled “eth0”. This is the primary I/P connection to the WCCIIIMCD2 device. See page XX for detailed instructions on how to
properly confi gure this network port for proper network access.
The auxiliary (second) Ethernet port on the WCCIII-MCD2 is
named and labeled “eth1”. This port confi guration should never
be changed or reconfi gured by the contractor or end user. It is
meant for direct connection (with a network cross-over cable) to
a Laptop that is to be used for setup, confi guration, updating, and
troubleshooting, or to a dedicated WCC3 computer that would be
set up to run the various WCC3 type programs that connect to the
WCCIII-MCD2 via a network connection.
Each port—etho0 and eth1—has two built in LEDs.
The Left LED is a bi-color Network Speed indicator:
LED Yellow on – Operating as a Gigabit connection (1000 Mbps)
LED Green on – Operating as a 100-Mbps connection.
LED Off – Operating as a 10-Mbps connection.
Wiring between the WCCIII-MCD2 and the satellite
controllers:
Basic rule of thumb when wiring communications from the
WCCIII-MCD2 to any and all Satellite connections: Wire “R”
connections to “R” connections, Wire “T” connections to “T”
connections, Wire “SH( SHLD)” connections to “SH (SHLD)”
connections, and there should not be an issue with communications
wiring.
13B-12
The Right LED is Link/Activity indicator:
LED Blinking – There is activity on this port.
LED Off – There is no network link established.

Input/Output Connections
Serial Port
The Serial port is a 9 Pin “AT – Type” port that is now only used
for extreme cases as a point of access in case the Ethernet ports
and VGA are non-functional for some unknown reason. See page
43 for how to connect to a Windows based computer running
Hyper-Terminal for access.
VGA Monitor & USB Key Board
Normal operation of the WCCIII-MCD2 does not require the use
of a VGA monitor and USB Keyboard, but a VGA Monitor and
a USB Keyboard may be required only for initial setup and/or
software updating if you choose not to use a network cross-over
cable, and the putty.exe program to confi gure and or update the
WCCIII-MCD2 device. The Webmin access program should not
generally be used to initially confi gure or update the WCCIII-
MCD2 device.
VGA Monitor & USB Key Board Connections
You may use any of the four external USB connections for the
USB keyboard, and these external USB connectors are located on
the bottom side of the WCCIII-MCD device. A standard 15 pin
VGA monitor will plug into the clearly marked VGA port plug on
the bottom side of the WCCIII-MCD2 device.
USB ports
There are 4 four USB ports provided on the bottom side for
the WCCIII-MCD2 device. These USB ports are meant to be
connected to the following devices: USB Keyboard, USB APC
UPS, and USB Memory stick(s). The USB memory stick is used
for program data backup, data restore, system updates, and system
reloading.
