Q5 CONTROLLER
MAIN BOARD HISTORY AND IDENTIFICATION
The processor board shown on this page is known as
the Q5 board, and it is based on the Pentium micro-
processor platform. The operating software that this
board runs is known as Quantum™ LX software. This
software displays graphic information and data on the
LCD screen in a format that is similar to the way a
Windows® desktop computer screen displays a Web
browser (the Internet).
The Q5 board can be identified by the presence of a
large aluminum heat sink located on the board. Ad-
jacent to the processor board, is an Interface board
which allows the user to attach local communications
connections via the four orange connectors (RS-422
and RS-485 ports).
There are also a number of jumpers present on both
the Q5 and the Interface board. These jumpers MAY
need to be modified by qualified personnel to configure
the Q5 for specific applications.
The Q5 utilizes Flash Card technology. There is a Flash
Card socket located on the under side of this main
board. The Q5 board has the LX Operating System pre-
loaded at the factory, so this Flash Card feature will
primarily be utilized for future program updates.
The information that follows will primarily describe the
jumper configuration for communications settings, as
well as wiring diagrams for the different types of com-
munications that are possible with the Q5.
