2.3  Control Circuit

There are 2 types of control circuit boards due to the interface specification.

SCSI Model: B104 Main Board

USB  Model: B104 Main-B Board

The difference is the only interface part with host.

2.3.1  Control Circuit Overview

Figure 2-6 is SCSI control circuit block diagram, and Figure 2-7 is for USB. This 
scanner uses the one-tip 16-bit bus CPU (IC10) at 20MHz frequency. Image 
data processing, correction, CCD sensor board, A/D converter control are 
operated at ASIC (IC8). Table 2-3 shows major IC functions.
