4 The MCPU BOARD A2 sends:
TG4825-1
Page
• "CASSETTE Detected" message to the MSC BOARD A1
25 of 120
• "Scan Request" message to the INTERNAL PC
5 The INTERNAL PC:
• checks that it has the quantity of memory necessary to receive an image
• makes a raw image file to receive the image
• sends a "Scan Request Reply" message to the MCPU BOARD A2 with a value of
"OK"
6 The MCPU BOARD A2:
• sends a message to the MSC BOARD A1 to load the CASSETTE
• sends the information about the size and speed of the CASSETTE to the DIGITIZER
BOARD
Note
If the BAR CODE readout is not successful, the operator must enter the data manually. When
BAR CODE data is entered manually, the data is provided by the INTERNAL PC and not the
BAR CODE READER.
7 The CASSETTE DRIVE MOTOR M2 actuates. The MOTOR drives the TIMING BELTS,
which rotate the DRIVE ROLLERS.
8 The DRIVE ROLLERS drive the CASSETTE to the back until the CASSETTE REAR
SENSOR S3 detects the CASSETTE.
9 The CASSETTE REAR SENSOR S3 sends a signal to the MSC BOARD A1 to
deactuate the MOTOR.
10 After a delay of 20 ms, the MSC BOARD A1 deactuates the MOTOR.
