A00 warns that there is no communication between the Display and the I/O card.
As a result the unit will interrupt any function and displays the message.
This message requires the intervention of an authorized technician; causes of the fault must be investigated as per prescriptions.
Description
The display is powered by the RJ45 connector that also transmits data. Two scenarios are possible; or we are in the presence of a bad electrical connection or the firmware in I/O board and the software of Display board are not aligned. In the latter case, the display will automatically try to update the FW in the I/O board.
Check if SW (display) is updated to V.12 for Reloaded V.20 for Boosted.
Warning
- The data cable with an RJ45 connector that connects the display to the I/O board must be connected to the KEYBOARD connector. By connecting it to the EXP connector, the I/O board will be irreparably damaged.
- Be careful not to tug the connecting cable as this may damage both the cable and the connector soldered to the board.
Checks
Check the following:
- RJ45 cable insertion on both cards.
- Try replacing the cable
- Try replacing the I / O board
- Replace the Display
