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 leader 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 LOOPBACK TEST

With version 5.0x Quantum™ 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 Quantum™ 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 Quantum™ 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:

Hardware Setup for RS-485 Testing

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

1. Decide which Quantum™ protocol you can

communicate with and want to use.

2. Setup your device’s communication port for the

Quantum™ protocol and select a baud rate.

3. 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.

4. Setup the baud rate of Com-2 to coincide with the

setup of the your device’s communication port.

5. Enter the Quantum™ 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 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.

QUANTUM™ COMPRESSOR CONTROL PANEL

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

Quantum™ 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 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.

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 Quantum™ panels.

When there is more than one panel, a Quantum™ 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.

The following is a complete list of available Frick® Protocol

# commands:

COMMAND CODE and DESCRIPTION

I = Returns compressor status information.

R = Compressor start control.

S = Compressor stop control.

V = Slide Valve/Slide stop control.

P = Return Pressures information.

A = Return full load amps information.

T = Return Temperatures information.

Q = Query setpoints data.

C = Enter Change setpoints mode.

MC = Change compressor mode.

MV = Change Slide Valve mode.

KF = Clear Failures.

KR = Clear remaining recycle delay time.

X = Return digital I/O status.

F = Return Failures.

All data is returned as integer values. If decimal positions

are assumed, then divide the data by the proper multiple

of 10 to get the actual value.

Temperature data, except for Suction Temperature, is

returned in the current temperature units as 3 characters

with no decimal position (i.e. 032 would represent 32

degrees Fahrenheit if the panel temperature units are in

Fahrenheit, or it would represent 32 degrees Celsius, if the

panel temperature units are in Celsius). Suction

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

COMMUNICATIONS SETUP Page 15

Quantum™ $ Protocol Specifications

Quantum™ ($) protocol commands have been added

specifically for the Quantum™. Unless otherwise shown, 9

characters are returned from the Quantum™ 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 Quantum™ returns a response without using

checksum error checking on the received command (refer

to the Data Packet section for more information). If the

Quantum™ 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

Quantum™ 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 Quantum™ panels on the

communications line that data is on its way. Following the $

symbol, type the ID code of the Quantum™ that you wish

to query (for instance 01 for the first Quantum™). After the

ID number, type a D1. The protocol code in the Quantum™

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 Quantum™ returned, not actual

data.
