Protocol Description; Quantum™ Protocols; Checklist For Setting Up Communication - Frick QUANTUM ACUair Setup

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.

Modbus ASCII serial

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
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.

•
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 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
jumpered.
