Features:
•
Dual Channel Support
: The Backplane includes labeled card slots for the Main Processor Board
and two complete channels consisting of an Analog Input Board and optional Analog Output Board
and/or Relay Output Board. Unique PCB dimensions and connector placement prevent accidental
insertion into a wrong card slot.
•
Locking Card-Guides
: Card-guides serve to maintain circuit-board alignment during insertion.
Once fully inserted, the circuit boards are secured by sliding a locking mechanism (red/silver pin)
located on each card-guide into the notched areas of each board. Reference section titled
Removing/Installing a Printed Circuit Board
•
DC Power-Supply Interface
: Receives DC power from a triple-output power-supply module.
These voltages may be further regulated prior to being distributed through the backplane to other
boards.
•
DC-to-DC Converter
: +5 VDC to +3 VDC regulator for low-voltage logic supply.
•
Audible Buzzer
: A piezo device used to signal keypress events and/or alarm conditions. Jumper
fields are available to disable the buzzer function or to select maximum volume.

Main Processor Board
With reference to Figure 3, the Main Process Board utilizes a SAM processor that executes the primary
system code. It is responsible for interpreting user-control activity and updating all menus and
messages to the LCD Board.
The board includes a terminal-block connector for attaching an external alarm (optional). Reference
for a description of available relay contacts for external wiring.

The system’s mode of operation is
defined by a combination of two on-board controls
–
a 2-position
slider-switch and a 3-position jumper field in accordance with
. The label values shown refer to
actual text on the PCB beneath their
respective controls. It’s important to note that the labels represent
the text that
remains visible
(unhidden) by either the slider or installed jumper
after
a selection is
made. Reference section titled
