COMMUNICATIONS SETUP
INTRODUCTION TO THE QUANTUM™ LX
QUANTUM™ DESCRIPTION
The Quantum™ LX control panel utilizes the
Quantum™ 4 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 Quantum™ 4, the physical
hardware of the controller is being referred 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 Quantum™ 4 controller contains
the physical Serial and Ethernet connections that the
user connects to, while the Quantum™ LX software
determines how those connections are used.
These connections are known as PROTOCOLS, and
are both hardware and software based. The hardware
portion of the protocol (Quantum™ 4) 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
operator 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.

HOW TO USE THIS MANUAL
The purpose of this manual is provide the necessary
information (protocols, data registers, wiring, etc.) to
allow the end user to reliably communicate 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
communications conversations on its own, it only
responds to queries (requests) from external devices.
For serial communications connections, refer to the
section entitled Quantum™ Serial Communication
for the correct wiring and jumper settings of RS-232,
RS-422, or RS-485. Also, refer to the drawing of the
Quantum™ 4 Main Board section to identify wiring
configurations for Com-2.
For Ethernet communications, refer to the section
entitled Ethernet and Networking. Ethernet does not
require any jumpers to be installed.
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.
