1.3 DataCORDER INTERFACE
The DataCORDER is capable of performing the following functions initiated by the DataView Program
1.3.1 Data Extraction
a. Daily Header Data
Recorded days are presented in the following format:
1. Day 1 date (month, day, year), sensor data, events, ...
2. Day 2 date (month, day, year), sensor data, events, ...
b. Sensor Data
Sensor data will be read based on either standard or generic configuration. Please refer to separately bound manuals
covering the Refrigeration Unit for further explanation of standard and generic configurations, see Table 1-2.
1.3.2 Events
Events will be transmitted to the DataCORDER as specified in Table 1-3, Table 1-4 and Table 1-5. The
DataCORDER compacts the events, disposing of repetitive events to save memory space. All events have a time and
date stamp.
