INTRODUCTION TO THE QUANTUM™ LX
QUANTUM™ DESCRIPTION
The Quantum™ LX control panel utilizes the Q4 and Q5
microprocessor board as the brains of the system. The
LX portion of the Quantum™ name actually refers to the
operating system (software), and the operator interface
(physical display and keypad). When you see the name Q4
or Q5, the physical hardware of the controller is being re-
ferred to (microprocessor), whereas Quantum™ LX refers
to the software, and how the operator interacts with the
software (through the display/keypad).
As an example, the Q4/Q5 controller contains the physical
Serial and Ethernet connections that the user connects to,
while the Quantum™ LX software determines how those

HOW TO USE THIS MANUAL

The purpose of this manual is provide the neces-
sary information (protocols, data registers, wir-
ing, etc.) to allow the end user to reliably com-
municate with the Quantum™ LX via various
communications methods (to be described later)
for the purpose of obtaining and sending data
and/or for Air Handler control.
The Quantum™ LX does NOT begin any com-
munications conversations on its own, it only
responds to queries (requests) from external de-
vices.

COMMUNICATIONS SETUP
The Operating (or Home) screen
connections are used.
These connections are known as PROTOCOLS, and are
both hardware and software based. The hardware por-
tion of the protocol tells how the wiring connections are
physically made, while the software portion (Quantum™
LX) tells how the data to the connection is to be formatted
and interpreted.
The Quantum™ LX software is based on a web browser
format, and has the capability of communication through
both Serial and Ethernet protocols.
The following screen is representative of what the opera-
tor will see when the unit is first powered up. This is called
the Home screen. Be aware that the content of the screen
and the air handler picture shown may differ, based upon
the actual configuration and installed options.
For Ethernet communications, refer to the sec-
tion entitled Ethernet and Networking. Ethernet
does not require any jumpers to be installed.
For serial communications connections, refer to
the sections entitled Quantum™ Serial Commu-
nication for the correct wiring and jumper set-
tings of RS-422, or RS-485. Also, refer to the
drawings of the Q4 or Q5 Main Board section to
identify wiring configurations.
For information on software protocols, refer to
the section entitled Protocol Description.
To access specific data within the Quantum™ LX,
refer to the Data Tables.
