MICROPROCESSOR
4.1 Temperature Control Microprocessor System
The temperature control Micro-Link 5 microprocessor system consists of a control module (controller), display
module, keypad and interconnecting wiring. The controller houses the temperature control software and the Data
-
CORDER software. The temperature control software functions to operate the unit components as required to pro
-
vide 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
. Coverage of the DataCORDER software is provided in
