Table 13B-1: MCD vs. MCD2
Main Differences Between MCD and MCD2
Main Differences Between the First Generation WCCIII-MCD and the
New WCCIII-MCD2 Computers
First generation WCC III-MCD (See Note 1) New WCCIII-MCD2
120VAC power supply with Power Supply Fan 24VAC power supply (50VA transformer supplied) – Fanless operation.
(This dedicated 24VAC Transformer offers an extra layer of Electrical
Isolation that the fi rst generation WCC III-MCD did not have.)
Intel “M” processor TM with CPU Fan Newer generation Intel “Atom Processor” TM Passive cooling – Fanless
Wall mounted big bulky case with chassis mounted Fan Wall mounted enclosure, Designed with the smallest possible foot print.
The three fans that were used on the fi rst generation of
WCC III-MCD, when combined made a lot of noise. Completely Fanless operation. Also this new WCCIII-MCD2 enclosure
intentionally matches the look and feel of the aluminum enclosures for
the SAT III, and Sat 3 C/D/E/F controllers
2 line by 20 character liquid crystal display that displayed 4 line by 20 character liquid crystal display Module with keypad and four
additional “Status” LEDs. This LCD Module also integrates all of the
necessary control signals for the ATX power supply functionality for the
WCCIII-MCD2.

“BackTask” program running in windows emulation mode. The “BackTask” program is now running in native Linux.
RS-485 Communications:
Two Isolated RS-485 Communications loops - Standard (Two more
RS-485 Communications loops were optionally available for an
additional cost) (Limited to 60 Sats per Loop - 240 Sats Max)
RS-485 Communications:
Four Isolated RS-485 Communications loops are provided - Standard.
(Limited to 60 Sats per Loop - 240 Sats Max)
One Ethernet port. (Referred to as “eth0”) Two Ethernet ports. (Referred to as “eth0” and “eth1”)
One of these two Ethernet ports (eth1) is used as a fi xed local IP address
for direct connection to a local on site computer, and or a setup Laptop/
Desktop computer for simplistic setup. The other Ethernet port “eth0” is
intended to be connected to the end customer’s network/internet/router.
Four external USB ports. Four external USB ports.
UPS Backup power loss method
24VAC transformer used for detection of loss of power.
The onboard power switch board would detect loss of
power and then shutdown the WCCIII-MCD USB connection to APC TM brand Smart UPS for automatic controlled
shutdown. This feature adds important information about the exact time
date, and duration logging of the specifi c power outage. See Note 3.
