Description of Self Test Items C-17
â—¼ Analysis to test failure
The drive goes wrong if the test result appears Error.
Backlight control of primary LCD monitor goes wrong if the test fails.
â—¼ 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.
It is recommended to replace primary LCD monitor if the test result is FAIL.
C.1.38 Z1101 Secondary LCD Monitor I2C Interconnection
Test
â—¼ Top test item
Communication self test between PC Module and MF FPGA
â—¼ Test content
Test whether I2C communication serial port between MF FPGA and secondary LCD works well.
The test generates secondary LCD’s saver, and then returns back. Secondary LCD’s brightness
decreases, and then returns back. Read the hardware and software versions of secondary LCD.
â—¼ Analysis to test failure
The drive goes wrong if the test result appears Error.
The interconnection between MF FPGA and secondary LCD goes wrong if the test result is FAIL.
â—¼ 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 secondary LCD and main unit is fixed well, and
then replace main monitor if the test result is FAIL.
