General Functions
The electronic and electronically based functions of the Microscopy
Module are identified as follows:
• High level hierarchical software control of lower-level functions,
• Communications between microcontrollers at adjacent hierarchical
levels via inter integrated circuit communications links,
• Communications with the Microscopy Module Computer via an
RS-232 link,
• Indications via visual displays of Microscopy Module status,
• Closed-loop control of some DC motors,
• Position sensing of various mechanical movements of the
subsystems,
• Open loop control (power off-on) of DC motors,
• Control of discrete DC solenoid valves,
• Control of a system of DC solenoid-actuated valves and sensing
proper operation of the valves,
• Sensing of the presence or absence of water based fluids in a
small-diameter tube, and the level of water based fluids in a waste
well,
• Electrical sensing of various digital and analog status signals,
• Control of high- and low- speed stepper motors
• Controlling and receiving data from a bar-code scanner
• Local ambient temperature sensing and DC fan-motor control
• Control (but not data) interfacing with the data-processing parts of
the iQ200
• The electronic serial number system, an electronic system for
identifying the individual assemblies, subassemblies and other
elements that represent the totality of the iQ200 Microscopy
Module.
