MICROPROCESSOR
3.1 TEMPERATURE CONTROL MICROPRO-
CESSOR SYSTEM
The temperature control Micro-Link 2i microprocessor
system (see Figure 3- 1) consists of a key pad, display
module, the control module & expansion module set
(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.
