1 Ethernet interface is on main board QS5003 of LDU3000/A.
CON1: Ethernet interface
For more about QS5003, please refer to the explanation below.
2.4.1 RS232
Where the system is offline, RS232 cable may be used to communicate with QS5003
to change screen content or settings.
Where it is VGA synchronous system, only RS232 cable should be used to update
CPU of QS5003.
The RS232 is used also for updating the Firmware of the LDU, therefore it is
mandatory to wire it to an easy accessible location
.

3 Maintenance of LDU3000 (A)
3.1 Backup LDU3000 to computer
IMPOSA Tools program should be used. For operation details, please refer to User’s Manual
of IMPOSA Tools. Then you can save the LDU information to computer.
Select Tool\Backup LDU date\Save to computer
Select a location for saving backup file and name the file to be saved.
Press “Backup” button to start backing up and wait until it stops.
3.2 Restoration and Maintenance
3.2.1 Replacement of LDU3000
Replace the main board inside LDU. Change for a new LDU main board, and connect
it to power supply, communication cables and optic fibre. Do make sure that all con-
nections are the same as before.
Configure Parameters. Open IMPOSA Tools and select Tool\Recover\Recover from
computer, and confirm the prompting message, open the LDU backup file from your
computer, for example, backup.LDU.
Press Restore to start backing up and then wait until it ends. You can follow the same
operations to update all the LDU(s) (if there are many LDUs).
Switch off and restart the power supply of LDU.
Check if the screen can work normally.
3.2.2 Replacement of Optical Fibre and Optical Fibre Plug
Optical Fibre should be multimode.
For outdoor use, the optical fibre is usually fusion spliced by expertise on-site and
doesn’t need to change.
For indoor use the optical fibre is usually grafted in the optical fibre connector. So you
need to be careful when inserting or unplugging the optical fibre head, not to damage
it.
Please take the following steps to unplug the optical fibre:
