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.

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 master 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.
