System Overview
2-19
Optical coupling
-
Optical coupling circuit is responsible for changing voltage level and isolating the ground of circuit at
each sides of optical coupler.
DAC
-
DAC (Digital Analog Converter) circuit is responsible for output analog signal, such as KV setting, mA
setting and mA pre-heat.
VFC
-
VFC (Voltage Frequency Converter) circuit is responsible for converting mA signal to frequency value
in order to implement mAs function.
Communication
-
RS422 protocol is used for MCU to communicate with workstation or DAP.
-
SPI protocol is used for MCU to communicate with Control Panel.
Indication
-
Indication circuit includes LED and buzzer, which are controlled by MCU and peripheral controller.
Miscellaneous hardware
-
Other circuits include power supply, supervisor circuit, watchdog circuit, clock generator, and security
control, etc.
Power Distribution
Power Supply Overview
The power of MCB is drove by power supply 1 & 2 via mother board, and +3.3V, +2.5V & +1.2V are generated
from +5V_PS1. Power supplies are listed as follows.
