QUANTUM™ IDENTIFICATION
Frick®Controls has over the years, strived to remain on
the cutting edge of microprocessor technology and
development. Because of the ever-increasing speed,
memory, features, and power of microprocessors, Frick®
Controls will continue to introduce the latest advancement
in microprocessor control technology.
Our microprocessor family has shared the name
Quantum™, over the past five years. There are currently
four controllers within this family. The first two of these
controllers (known as Quantum™ 1 and Quantum™ 2) are
no longer in production, and as such, will not be further
mentioned in this manual. The two current members in
production of the Quantum™ family are the Quantum™ 3,
and the Quantum™ 4. It is critical to the end user to be
able to identify the differences between these controllers.
Refer to the section in this manual entitled Quantum™ 3
Main Board History and Identification and Quantum™ 4
Main Board History and Identification for additional
information as to how to identify the particular Quantum™
controller that you have.
Throughout this manual, the two different controllers will
be talked about for the most part as one (as they do
function the same). Where there is a difference between
these boards, as in jumpers or wiring, the different models
will be identified by name. This is why it is important for
you to be aware of which Quantum™ board you have.
Quantum™ 3
Quantum™ 4
Setting Up the Quantum™ for
Communication
Data communication to and from the Quantum™ can be
through a modem, remote data communications terminal,
programmable controller, or master computer via either
RS-422, RS-232, or RS-485 connections to the
Quantum™ Com-2 port. Reference the Main Board
Communications section for the correct jumpering of RS-
422, RS-232, or RS-485. Also, reference the drawing of
the Quantum™ Main Board section to identify wiring
configurations for Com-2.

RS-232 Communications
Following is the pin connections showing how to wire a
standard 9-Pin RS-232 connector directly to the 10-Pin
RS-232 connector on the Quantum™ 3, and the 3-pin
connector on the Quantum™ 4:
QUANTUM™ 3
Reference the drawing of the main processor board for the
location and positioning of the 10-Pin RS-232 connector.
Following is the pin positions of the 10-Pin connector:
Note: The TX2 and RX2 are I/O communication activity
lamps on the Quantum™ Main Processor Board that can
be monitored to see if the Com-2 port is receiving (RX2)
and transmitting (TX2) data.
QUANTUM™ 4
Reference the drawing of the main processor board for the
location and positioning of the 3-Pin RS-232 connector.
Following is the pin positions of the 3-Pin connector:
Converting an RS-232 Serial Port to RS-422 or
RS-485
In order to communicate to the Quantum™ controller via
RS-422 (or RS-485), you will need to convert the RS-232
signal from the source.
One converter that has proven to be effective is the Opto-
22 AC7A/B card. This card will allow the conversion from a
standard RS-232 signal to either RS-422 or RS-485. The
AC7A card is powered from a 115 VAC source, while the
AC7B card is powered from a 220 VAC source. They can
be used in a standalone panel along with an Allen Bradley
SLC 5/04 or along with an external modem. Keeping the
jumpers installed the same way they are received from the
factory, it is easy to wire for either RS-422 or RS-485.
NOTE: Refer to the manual that comes with the AC7A/B
card for specific jumper information (as the configuration
shown is only a suggestion that has worked in most
applications).
Once jumpers on the converter card have been verified,
you will need to verify the jumper settings of the
Quantum™ controller. Refer to the following diagrams for
the Quantum™ 3 and Quantum™ 4:
Quantum™ 3
Quantum™ 4
NOTE: Some of these jumper settings may need to be
modified to ensure optimum communications
performance. Typically, the termination jumper should be
installed in the last Quantum™ in the communications
daisy chain only (Link 7 for the Quantum™ 3, Link 1 for
the Quantum™ 4).

COMMUNICATIONS SETUP Page 9
PROTOCOL DESCRIPTION
The use of communication protocols, permits data
transmission between devices. Protocol determines how
contact is established and how the query (question) and
response (answer) takes place. The information in a
message command requires an identity of the intended
receiver (ID #), what the receiver is to do (read or write to
a setpoint, etc.), data needed to perform an action (the
value of a setpoint to be changed), and a means of
checking for errors (checksum).
When using Com-2 for communication, check what
communication protocol, if any has been selected, from
the Panel Setup – Change Communications screen. For
example, [A-B Comm] should be selected when using
Allen-Bradley’s communication protocol. The baud rate of
Com-2 and the panel ID number are also changed from
this screen, and should coincide with the setup of the
other device.
Note: The data communication protocols are continuously
being expanded and improved. Therefore, you should
consult Frick®Controls for the exact details on your
particular unit(s) before developing system software to
interface with the panel.
Quantum™ Communications Protocols
The Quantum™ controller has the capability of
communicating to the outside world through four software
protocols:
•Frick®
•Allen-Bradley DF-1 serial
•ModBus ASCII serial
•YORK ISN
Note: When using Modbus protocol, a [Comm. 2
Advanced] key will appear. Pressing this key will
allow the user to modify the number of Data and Stop
bits, as well as Parity. This only applies to Modbus.
Modbus cannot be changed from ASCII to RTU
however. Refer to the section on Modbus for further
information.
Checklist For Setting Up Communication
0191 Decide which Quantum™ protocol you
can communicate with and want to use.
0191 Setup your device’s communication port
for the Quantum™ protocol and select a baud
rate.
0191 Next, setup the Quantum™ for the desired
communication protocol. Select the protocol from
the Panel Setup – Change Communications
screen. For example, [A-B Comm] should be
selected when using Allen-Bradley’s
communication protocol.
0191 Setup the baud rate of Com-2 to coincide
with the setup of the your device’s
communication port.
0191 Enter the Quantum™ ID. This will be used
to identify commands that are sent to it.
0191 Wire to the first panel via RS-232, RS-
422, or RS-485 connections to the Quantum™
Com-2 port.
•If you are communicating to more than one
panel, then you will not be able to use RS-
232. You can however, convert RS-232 to
either RS-422 or RS-485 with an adapter
card. Reference the Converting an RS-232
Serial Port to RS-422 or RS-485 section for
information about an adapter card.

•Reference the drawing of the Quantum™
Main Board in this manual to identify wiring
and jumpering locations for Com-2.
•Reference the Main Board Communications
Com-2 section in this manual for the correct
jumpering of RS-232, RS-422, or RS-485.
0191 Send a single command to read data from
this Quantum™ using its ID.
0191 Check if you received a data response at
your device.
0191 Troubleshooting when you don’t receive a
data response:
•Check if Com-2 on the Operating Status
screen is showing ACTIVE or OFF.
•ACTIVE is shown only when the Quantum™
understands it is receiving a properly
composed message to itself.
•Check that the RX2 I/O communication
activity lamp on the Quantum™ Main
Processor Board is blinking as it receives the
instruction from your device.
•A steady lit RX2 LED or one that isn’t
lighting, are signs of improper wiring.
•If the RX2 LED is properly blinking, then
check if the TX2 LED is blinking in response.
•If the TX2 is not blinking then check the
communication protocol setup at the panel,
the panel’s ID and the Com-2 baud rate
setting.
•If the TX2 is blinking, then check that the
Com-2 communication jumpers are correct.
•If you are sure that the wiring and
Quantum™ setup is correct, then select the
[Show Comms] key from the Service
Screen to see what is being received and
transmitted from Com-2.
Note: A useful tool for troubleshooting is Windows
HyperTerminal. Using HyperTerminal can help you
determine if you are wired OK. Reference the
HyperTerminal Setup section in this manual.
0191 If you properly receive data and you need
to communicate to more than one panel, then
setup and wire to another panel. Reference the
wiring diagram drawings in the back of this
manual. Send a single command to read data
from this Quantum™ using it’s ID and
troubleshoot as above, if necessary. To prevent
noise feedback which is possible when
communicating over a long distance, only the last
panel should have the termination for long
communications lines jumpered.
