Overview
The MicroVission control panel utilizes the ARM PC tech-
nology with a Linux operating system. For hardware ar-
chitecture, see Figure 2-1.

Multi-I/O (Input/Output) Board

This section explains about the Multi-IO board con-
taining Digital Input/Output and Analog Input/Output
signals.
The Multi-IO board converts signals generated by the
MicroVission program into 120VAC signals as well as de-
tect external 120VAC inputs to signal the MicroVission
program. All the signals shown by connectors 1, 2, 3 and
4 are digital, in that there are only two states available
either ON or OFF. See board layout, Figure 2-2.

Figure 2-1. Hardware Architecture Overview

The MicroVission has the following attributes
• Low power, Industrial rated ARM CPU
• 10" XGA, high resolution LCD display. (Outdoor view-
able LCD optional)
• 8-wire touch screen operator interface
• Flexible and expandable I/O
• NEMA-4 enclosure (NEMA-4X optional)
• Industrial temperature range design
The Multi-IO board converts the varying DC signals into a
signal that the MicroVission program can interpret. The
signals are considered analog because the input DC sig-
nal can vary from the minimum value to the maximum
value. All the signals shown by connectors 6, 7, 8, 9 and
10 are analog inputs. This board can also convert signals
from the MicroVission program into a current ranging
from 4mA to 20mA. These are called analog outputs and
shown by connectors 12 and 13. For more information
about the board layout see Figure 2-2.
