QUANTUMâ„¢ 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
Quantumâ„¢, over the past five years. There are currently
four controllers within this family. The first two of these
controllers (known as Quantumâ„¢ 1 and Quantumâ„¢ 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 Quantumâ„¢ family are the Quantumâ„¢ 3,
and the Quantumâ„¢ 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 Quantumâ„¢ 3
Main Board History and Identification and Quantumâ„¢ 4
Main Board History and Identification for additional
information as to how to identify the particular Quantumâ„¢
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 Quantumâ„¢ board you have.
Quantumâ„¢ 3
Quantumâ„¢ 4
Setting Up the Quantumâ„¢ for
Communication
Data communication to and from the Quantumâ„¢ can be
through a modem, remote data communications terminal,
programmable controller, or leader computer via either
RS-422, RS-232, or RS-485 connections to the
Quantumâ„¢ 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 Quantumâ„¢ 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 Quantumâ„¢ 3, and the 3-pin
connector on the Quantumâ„¢ 4:
QUANTUMâ„¢ 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 Quantumâ„¢ Main Processor Board that can
be monitored to see if the Com-2 port is receiving (RX2)
and transmitting (TX2) data.
QUANTUMâ„¢ 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 Quantumâ„¢ 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
Quantumâ„¢ controller. Refer to the following diagrams for
the Quantumâ„¢ 3 and Quantumâ„¢ 4:
Quantumâ„¢ 3
Quantumâ„¢ 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 Quantumâ„¢ in the communications
daisy chain only (Link 7 for the Quantumâ„¢ 3, Link 1 for
the Quantumâ„¢ 4).

COMMUNICATIONS LOOPBACK TEST
With version 5.0x Quantumâ„¢ software, a method of
testing the onboard RS-422 and RS-485 communications
ports was developed. By utilizing a loopback test harness
(as shown below), the maintenance technician now has
the ability to locally test the Quantumâ„¢ communications
hardware and jumper configuration.
Hardware Setup for RS-422 Testing
To create the test harness for RS-422 communications
loopback testing, use the following example:
Set the Quantumâ„¢ 4 communications jumpers as follows:
• Set LK11 to position B
• Set LK16 to position A
• Set LK17 to position A
• Plug the RS-422 test harness (as shown above)
into the com ports at TB1 and TB2 as shown
here:

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.
Quantumâ„¢ Communications Protocols
The Quantumâ„¢ 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
1. Decide which Quantumâ„¢ protocol you can
communicate with and want to use.
2. Setup your device’s communication port for the
Quantumâ„¢ protocol and select a baud rate.
3. Next, setup the Quantumâ„¢ 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.
4. Setup the baud rate of Com-2 to coincide with the
setup of the your device’s communication port.
5. Enter the Quantumâ„¢ ID. This will be used to
identify commands that are sent to it.
6. Wire to the first panel via RS-232, RS-422, or
RS-485 connections to the Quantumâ„¢ 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.

Page 10 COMMUNICATIONS SETUP
• Reference the Main Board Communications
Com-2 section in this manual for the correct
jumpering of RS-232, RS-422, or RS-485.
7. Send a single command to read data from this
Quantumâ„¢ using its ID.
8. Check if you received a data response at your
device.
9. 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 Quantumâ„¢ 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
Quantumâ„¢ 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.
10. 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.

Frick® Protocols
All commands for Frick® protocols must be in ASCII to be
recognized (see the Conversion Chart For Decimal /
Hexadecimal / ASCII, located later in this manual). The
data should be setup as an 8 bit Word with no Parity, and
a Stop Bit. The commands can be in upper or lower case
letters. A compressor with an ID code of [00] is considered
disabled. ID codes from [01] through [99] are valid and
recognized by the microprocessor.
Frick® # Protocol Specifications
Frick® # protocol consists of commands that are available
for most other existing models of Frick control panels. The
Frick® # protocol does not utilize a checksum. It is better to
use Frick® Quantum™ ($) protocol when only
communicating to Quantumâ„¢ panels.
When there is more than one panel, a Quantumâ„¢ can be
wired from it’s Com-2 to another panels Com-2 or can be
wired from it’s Com-2 to Port 1 of a RWB, RDB, RXB or
RXF Micro Plus panel.

Temperature is returned as 4 characters with a + or - as
the leading character (i.e. –010 would represent –10
degree).
Pressure data is usually returned in the current pressure
units. However, the Filter differential reading is always
returned in PSIA. When in PSIG or in PSIA, the pressure
data is returned as 3 characters with no decimal position.
However; in order to show the full transducer range, the
#IDPS command returns 4 characters with one decimal
position assumed. The #IDI, and #IDPA commands return
3 characters that assume one decimal position; therefore,
99.9 is the highest value that can be returned. When in
PSIG, suction pressure is returned in PSIA. When in Bar
and BarA, the pressure data is returned as 4 characters
with two decimal positions assumed. When in KpaA, the
pressure data is returned as 4 characters with no decimal
position.

QUANTUMâ„¢ COMPRESSOR CONTROL PANEL S90-010 CS
COMMUNICATIONS SETUP Page 15
Quantumâ„¢ $ Protocol Specifications
Quantumâ„¢ ($) protocol commands have been added
specifically for the Quantumâ„¢. Unless otherwise shown, 9
characters are returned from the Quantumâ„¢ for a data
value. The data value includes two decimal fields and the
first character position is either; - if the value is negative,
or it is + if the value is positive. For example, if the data’s
value is 25.5; then the value +00002550 is sent. All
temperatures are in degree C and all pressures are in
PSIA. A mode such as Slide Valve mode is returned as an
integer value that represents the mode that it is in. For
example, a +00000000 is sent if it is in manual, or a
+00000100 is sent if it is in automatic, or a +00000200 is
sent if it is in remote. The value zero +00000000 is used to
represent an OFF status and a DISABLED option. The
value one +00000100, which is received as a 1, is used to
represent an ON status and an ENABLED option.
Setpoints are only changed if the value sent is within the
acceptable range. Reference the Frick® Quantum™
Control Panel Maintenance publication S90-010 M for the
setpoints default settings and ranges. The checksum is
the 2 byte hexadecimal sum of each character within the
command or returned answer excluding the command
type identifier, $. If the command’s checksum is replaced
with ??, the Quantumâ„¢ returns a response without using
checksum error checking on the received command (refer
to the Data Packet section for more information). If the
Quantumâ„¢ detects a checksum error, a N (Not
Acknowledged), the Compressor ID code, 02, Carriage
return, and Linefeed are returned.
This document will demonstrate how to communicate to the
Quantumâ„¢ panel using the tables that appear on the
following pages.
Data Packet
If you were interested in viewing the information that is
displayed on the Operating Status - Page 1 screen
(Home screen), you would want to refer to the table
entitled RETURN OPERATING STATUS Page 1 data:
$01D1 table on the next page.
The quickest and easiest way to demonstrate this protocol
is through Hyperterminal (see the section entitled
Hyperterminal later in this manual). After setting up
Hyperterminal and ensuring that all wiring and jumper
configurations are correct, type a $ symbol. This is the
character that will alert all of the Quantumâ„¢ panels on the
communications line that data is on its way. Following the $
symbol, type the ID code of the Quantumâ„¢ that you wish
to query (for instance 01 for the first Quantumâ„¢). After the
ID number, type a D1. The protocol code in the Quantumâ„¢
recognizes this portion of the data packet as a request for
the data that is displayed on the Operating Status - Page
1 screen.
Up to now you have typed the following information:
$01D1. The next thing that must be done is to enter a
checksum value. You may elect to type in a ?? as a
wildcard if you do not have the time to figure the correct
checksum, however, the information that is returned may or
may not always be reliable. The checksum will ensure
reliability.
To arrive at the checksum value for the command you have
just typed, you will need to convert each ASCII digit into
hexadecimal (do not include the $ symbol). For this
example, you will need to take the first digit 0, and referring
to the Conversion Chart at the end of this section, look
down the ASCII column until you find 0. You will notice that
the Hexadecimal equivalent for ASCII 0 is 30 hex. Repeat
the process of looking up each digit in the ASCII column,
and finding its equivalent in the Hexadecimal column, and
write each value down. When all four digits (01D1) have
been converted to hexadecimal, you will need to add the
four values together. Remember, the values are in
hexadecimal format, not decimal. If you are not familiar
with hexadecimal math, you may wish to utilize the
calculator that comes with Microsoft Windows. Look at the
following chart:
ASCII Value of
Data Packaet Hexadecimal
Equivalent
030
131
D44
131
Hex Total = D6
The answer that is arrived at from the previous chart is D6.
This will become the checksum for the data packet, and is
appended to the end of the data that has so far been typed
in.
NOTE: For any calculation that results in an answer of
more than two digits, use only the right most two digits, and
disregard all digits to the left.
The result should look like this:
$01D1D6
Press the [Enter] key. You should see an immediate
response. The format of this response should resemble
something (but not necessarily exactly) like:
A01+00006166+00008618+00008272+00002974+000154
15+00005314+00008501+00000000+00000000+0000000
0+00000341+00000231-00027249B6
Referring to the RETURN OPERATING STATUS Page 1
data: $01D1 table on the next page, we find that the first
line of the response, A01, indicates that an
Acknowledgement (A) was received from device 01 (01).
This is followed by +00006166 (Suction Pressure). The
plus (+) symbol indicates a positive value, followed by
00006166. Since there are two decimal positions assumed,
0006166 equals 61.66 PSIA. Using the +/- symbols as a
delimiter in the above example, each section of 8 digits can
be interpreted by comparing it with the Operating Status
table. The B6 value at the very end of the response is the
checksum value that the Quantumâ„¢ returned, not actual
data.
