CAUTION:
DURING THE UPLOADING OF THE SOFTWARE COMPONENTS TO THE ATSU (FIN'S 20TXSW1, 21TXSW1, 30TXSW1, 23TXSW1, 25TXSW1, 35TXSW1, 36TXSW1, 39TXSW1, 37TXSW1, 22TXSW1, 24TXSW1, 31TXSW1, 42TXSW1), MAKE SURE THAT: IF YOU DO NOT OBEY THESE TWO PRECAUTIONS, THERE CAN BE ERASURE OF ALL THE SOFTWARE COMPONENTS LOADED INTO THE ATSU. IT CAN THEN BE NECESSARY TO START THE UPLOADING PROCEDURE OF ALL THE ATSU SOFTWARE COMPONENTS AGAIN.
A. Loading Procedure of the ATSU Software -
MAINTENANCE PERSONNEL DO NOT CHANGE THE SOURCE OF THE AIRCRAFT POWER SUPPLY (GROUND POWER UNIT, APU, ETC.) - MAINTENANCE PERSONNEL DO NOT TOUCH OR MOVE THE DATA LOADER SELECTOR(S)/DLRB AND THE MDDU/PDL.
NOTE: The loading time for a full disk is twelve minutes approximately.
Upload the ATSU software in this sequence: - ATSU A/C INTERFACE software disk (20TX)
- ATSU CONFIGURATION software disk (21TX)
- ATSU ROUTER PARAMETERS software disk (30TX)
NOTE: Between each software uploading procedure:
- Set the ON/OFF switch on the portable data loader to OFF
- Disconnect the portable data loader
- Connect again the portable data loader
NOTE: The loading time for a full disk changes in relation to the software. The maximum loading time is 40 minutes.
NOTE: On the MCDU, after the uploading procedures, the operator must do a check of the reference of the software loaded in the computer.
NOTE: When you upload the FIN 30TX, if the P/Ns of the FINs 20TX and 30TX are not compatible:
- It is necessary to upload again the ATSU software 20TX and 21TX.

NOTE: If more than one disk are necessary to do the uploading, the EJECT DISK and INSERT NEXT DISK indications are shown one after the other. They tell the operator to put a new disk into the portable data loader. NOTE: If more than one disk are necessary to do the uploading and if a transfer fault occurs, the uploading must be resumed from the beginning (i.e. from disk 1). NOTE: On the upper ECAM DU, the COM ACARS FAULT or DATALINK ATSU FAULT warning is shown when you upload the ATSU A/C INTERFACE software. |

CAUTION:
DURING THE UPLOADING OF THE SOFTWARE COMPONENTS TO THE ATSU (FIN'S 20TXSW1, 21TXSW1, 30TXSW1, 23TXSW1, 25TXSW1, 35TXSW1, 36TXSW1, 39TXSW1, 37TXSW1, 22TXSW1, 24TXSW1, 31TXSW1, 42TXSW1), MAKE SURE THAT: IF YOU DO NOT OBEY THESE TWO PRECAUTIONS, THERE CAN BE ERASURE OF ALL THE SOFTWARE COMPONENTS LOADED INTO THE ATSU. IT CAN THEN BE NECESSARY TO START THE UPLOADING PROCEDURE OF ALL THE ATSU SOFTWARE COMPONENTS AGAIN.
B. Uploading of the ATSU Applications -
MAINTENANCE PERSONNEL DO NOT CHANGE THE SOURCE OF THE AIRCRAFT POWER SUPPLY (GROUND POWER UNIT, APU, ETC.) - MAINTENANCE PERSONNEL DO NOT TOUCH OR MOVE THE DATA LOADER SELECTOR(S)/DLRB AND THE MDDU/PDL.
NOTE: The loading time for a full disk is 40 minutes maximum.
You can upload all the software disks that follow in this sequence and one after the other: - AOC SOFTWARE disk (22TX)
- AOC DATABASE disk (24TX).
NOTE: Between each software uploading procedure:
- Set the ON/OFF switch on the portable data loader to OFF
- Disconnect the portable data loader
- Connect again the portable data loader
NOTE: On the MCDU, after the uploading procedures, the operator must do a check of the reference of the software loaded in the computer.
NOTE: During the uploading of the FIN 24TX customized, if you disconnect the MDDU before the TRANSF COMPLETE or TRANSF FAILED indication is shown:
- It will be necessary to upload again all the software loaded in the ATSU (this is not applicable to FIN 20TX).
NOTE: If FIN 22TX and FIN 24TX were uploaded and if it is necessary to upload them again:
- It is necessary to upload all ATSU software from the 20TX.
