Description of Self Test Items C-13
Suggestion to failure test
Replace the control panel if LED brightness does not respond.
C.1.29 Z0901 Primary LCD Monitor I2C Interconnection
Test
Top test item
Communication self test between PC Module and MF FPGA
Test content
Test whether I2C communication serial port between MF FPGA and primary LCD monitor works
well. The test generates primary LCD monitor’s saver, and then restores it. Primary LCD monitor’s
brightness decreases, and then returns back. Read the hardware and software versions of
primary LCD monitor.
Analysis to test failure
The drive goes wrong if the test result appears Error.
The interconnection between DSP FPGA and primary LCD monitor goes wrong if the test result is
FAIL.
Suggestion to failure test
Restart the device to perform the self test if the test result appears Error. It is necessary to restore
the device (OS+doppler) if Error re-appears.
Check whether the connecting material between primary LCD monitor and main unit is fixed well,
and then replace primary LCD monitor if the test result is FAIL.
