Carrier Container Refrigeration Unit DataCORDER INTERFACE, Data Extraction a. Daily Header Data

1.3 DataCORDER INTERFACE

The DataCORDER is capable of performing the following functions initiated by the DataView Program

1.3.1Data 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.
