1. If the test result is FAIL, check whether the network cable is connected in place.
2. Ensure that the network cable is connected in place. If the test result is still FAIL, replace the
main board.
Z0207 RF Chip SPI Test
• Upper-level test item
Communication Test Between PC Module and MF FPGA
• Test Items
Turn on the RF chip. Read the register of the RF chip through SPI to judge whether the written
data is consistent with the received data.
• Test failure analysis
If the test result is Error, the drive is abnormal.
If the test result is FAIL, the SPI port of the RF chip is abnormal.
• Troubleshooting suggestion
1. If the test result is Error, restart the device and re-perform the self-test. If the problem persists,
restore the device.
2. If the test result is FAIL, replace the main board.
Z0208 CW_SPI Interface Test
• Upper-level test item
Communication Test Between PC Module and MF FPGA
• Test Items
Enable the CW test mode and enter the CW automated test to determine whether the CW_SPI
port is normal.
• Test failure analysis
If the test result is Error, the drive is abnormal.
If the test result is FAIL, the CW_SPI board interface goes wrong.
• Troubleshooting suggestion
1. If the test result is Error, restart the device and re-perform the self-test. If the problem persists,
restore the device.
2. If the test result is FAIL, replace the main board.
Z0209 CW Mode Pressure Test
• Upper-level test item
Communication Test Between PC Module and MF FPGA
• Test Items
On the FPGA, set the PHV voltage and then the CW voltage. Read and check whether the
voltage value is within the specified range.
• Test failure analysis
