Teledyne API – Model T300/T300M CO Analyzer 
Theory of Operation 
309
 
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 Teledyne API 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.
