Checking of BOARDS During Initializing
TG4825-1
Page
When the CR 825/850 SYSTEM is energized, an initializing process occurs, in which
98 of 120
BOARDS and software operations are checked and hardware components are moved to the
home position. When the CR 825/850 SYSTEM is successfully initialized, the main menu
appears on the TOUCH SCREEN MONITOR.
Sequence of operations during initializing:
INTERNAL PC
MCPU BOARD
A2
• The software of the INTERNAL PC checks all the system components:
– memory
– DISK DRIVES
– KEYBOARD and MOUSE
– network hardware
• The operating system loads and starts running. The software for the
CR 825/850 SYSTEM starts automatically when the operating system is
running. The first component to energize is the MCPU BOARD A2.
• The BOOT CODE of the MCPU BOARD A2 provides configuration
information for the MICROCONTROLLER and checks the memory.
• The BOOT CODE checks the main application program on the PCMCIA
CARD under the MCPU BOARD A2 and loads it into the main memory
of the MCPU BOARD A2.
• The application program for the CR 825/850 SYSTEM starts.
• The BOOT CODE checks that the MCPU BOARD A2 signals can be
sent between the MSC BOARD and the INTERNAL PC.
• The BOOT CODE of the MCPU BOARD A2 reads the calibration data
stored on the PCMCIA CARD.
• The BOOT CODE of the MCPU BOARD A2 checks the DIGITIZER
BOARD A3 using a diagnostic program on the DIGITIZER BOARD A3.
