Theory of Operation

Model GFC7000TA Carbon Dioxide Analyzer

9.3.2. CPU

The unit’s CPU card, installed on the motherboard inside the rear panel, is a low power (5 VDC, 720mA max), high performance, Vortex 86SX-based microcomputer running Windows CE. Its operation and assembly conform to the PC/104 specification.

The CPU includes two types of non-volatile data storage: a Disk on Module (DOM) and an embedded flash chip.

9.3.2.1. Disk-On-Module (DOM)

The DOM is a 44-pin IDE flash chip with storage capacity to 129 MB. It is used to store the operating system, the Teledyne firmware, and most of the operational data generated by the analyzer’s internal data acquisition system (DAS - See Section 6.7).

9.3.2.2. Flash Chip

This non-volatile, embedded flash chip includes 2MB of storage for calibration data as well as a backup of the analyzer configuration. Storing these key data on a separate, less heavily accessed chip significantly decreases the chance of data corruption. In the unlikely event that the flash chip should fail, the analyzer will continue to operate with just the DOM. However, all configuration information will be lost, requiring that the unit be recalibrated.
