Stop Bits - A bit(s) which signals the end of a unit
of transmission on a serial line. A pull down menu is
provided to select from the following:
• 1
• 2
Parity - In communications, parity checking refers to
the use of parity bits to check that data has been
transmitted accurately. The parity bit is added to ev-
ery data unit (typically seven or eight data bits) that
are transmitted. The parity bit for each unit is set so
that all bytes have either an odd number or an even
number of set bits. Parity checking is the most ba-
sic form of error detection in communications. A pull
down menu is provided to select from the following:
• None
• Even
• Odd
Protocol - A protocol is the special set of rules that
each end of a communications connection use when
they communicate. A pull down menu is provided to
select from the following Frick recognized protocols:
• None
• Frick
• ModBus
ASCII
• ModBus RTU
• AB DF1 Full Duplex
• AB DF1 Half Duplex
• DBS Motor Starter
• Vyper
Map File - Because the addressing scheme between the
Quantum™ version 5.0x and earlier software and the
Quantum™ LX version 6.0x and later software is not the
same, this fi le was created. The map fi le is a conversion
utility that can be used to allow a communications appli-
cation that was previously written by the user under the
Quantum™ version 5.0x and earlier to function properly
with the Quantum™ LX by redirecting the old addresses
to the new addresses (see the section entitled Using the
MAP fi le for additional information). A pull down menu is
provided to select from the following:
• No - Do not use map fi le. The user is either not
going to be using external communications, or
they will be writing the communication applica-
tion based upon Quantum™ LX addresses.
• Yes - The user has an application that was previ-
ously written for the Quantum™ version 5.0x or
earlier, and they want to utilize the same code
for the Quantum™ LX.
I/O Comms - A status indicator is provided to show the
current state of the internal communications of the I/O
boards. The possible displayed states are:
• Off - Loss of or intermittent communications
failures to the internal Quantum™ LX I/O boards.
• Active - Indicates that normal I/O communica-
tions are occurring.
• Failed - Loss of communications, a shutdown
message will be generated.
Redetect IO Comms - Select this key to detect all con-
nected Analog and Digital boards. If a board has been re-
moved, a communication error shutdown will be issued
until this key is selected. Reference the About screen to
view what has been detected.
Two keys are located at the bottom right hand side of the
screen. The following describes there function:
Download MapFile.txt from Quantum™ LX – With
a USB memory stick installed on the LX, pressing this
key will cause the MapFile.txt fi le to be downloaded
from the Quantum™ LX into the USB memory.
Upload MapFile.txt to Quantum™ LX – After the
user has modi fi ed the MapFile.txt fi le to suit their
needs, pressing this key will cause the fi le to be up-
loaded from the USB memory back into the Quan-
tum™ LX.
USING THE MAP FILE
The MAP fi le is simply a text fi le (map.txt), which can be
downloaded from the Quantum™ panel. The fi le can be
used in its original format, which contains a limited num-
ber of addresses, or may be modi fi ed by the user, to in-
corporate additional addresses.
Downloading The Map File From The Quantum™ LX
Through a Web Browser:
To download the map fi le from the Quantum™ LX
controller, click the Download button. A new box will
appear with a link labeled MapFile.txt. Right click on
the link, and select Save Link Target As… from the
menu. The web browser will then present a dialog
box allowing the user select a location on their com-
puter for the map fi le to be stored. (NOTE: This op-
eration is not intended to be performed from the Op-
erator Interface Panel. Instead, a desktop computer
should be used to access the Evaporator controller
via a web browser).
Downloading the MAP File From the Panel Using a USB
Memory Stick:
Two keys are located at the bottom right side of the
screen. The following describes there function:
