MICROPROCESSOR
3.1 TEMPERATURE CONTROL MICROPRO-
CESSOR SYSTEM
The temperature control Micro-Link 3 microprocessor
system (see Figure 3--1) consists of a key pad, display
module,
the
control
module
(controller)
and
interconnecting wiring. The controller houses the
temperature control software and the DataCORDER
software. The temperature control software functions to
operate the unit components as required to provide the
desired cargo temperature and humidity. The
DataCORDER software functions to record unit
operating
parameters
and
cargo
temperature
parameters for future retrieval. Coverage of the
temperature control software begins with paragraph 3.2.
Coverage of the DataCORDER software is provided in
paragraph 3.6.
The key pad and display module serve to provide user
access and readouts for both of the controller functions,
temperature control and DataCORDER. The functions
are accessed by key pad selections and viewed on the
display module. The components are designed to
permit ease of installation and removal.
