13.4.1. CPU
The unit’s CPU card is installed on the motherboard located inside the rear panel. It 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.
Figure 13-10. CPU Board
The CPU includes two types of non-volatile data storage: a Disk-On-Module (DOM)
and an embedded flash chip.
13.4.1.1. DISK-ON-MODULE (DOM)
The DOM is a 44-pin IDE flash drive with a storage capacity up to 128 MB. It is used to
store the computer’s operating system, the TAI firmware, and most of the operational
data generated by the analyzer’s internal data acquisition system (DAS).
13.4.1.2. 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 on a less heavily
accessed chip significantly decreases the chance of data corruption.
