6200T Total Sulfur Analyzer Principles of Operation
Teledyen Analytical Instruments 305
13.5.1. CPU
The unit’s CPU card, installed on the motherboard located 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.
13.5.1.1. Disk On Module (DOM)
The DOM is a 44-pin IDE flash chip with storage capacity to 256 MB. It is used to store
the computer’s operating system, the Teledyne Analytical Instruments firmware, and
most of the operational data generated by the analyzer’s internal data acquisition system
(DAS). Embedded in the DOM is a flash chip.
13.5.1.2. 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 onto a less heavily
accessed chip significantly decreases the chance data corruption.
