There are two independent COM interfaces in mainboard QS5003 of LDU3000(A)

• COM1: RS232 or RS485; If SEL (connecting to GND) is selected, the communication should be RS232; If SEL is suspended, the communication be RS485; RS232 and RS485 cannot be used together.

• COM2: RS232 There is one Ethernet interface in mainboard QS5003 of LDU3000/A.

• CON1: Ethernet interface For more about QS5003, please refer to the explanation below.

2.4.1 RS232 1) Where the system is offline, RS232 cable may be used to communicate with QS5003 to change screen content or settings. 2 ）W here it is V QS5003. Note: No matter if it is an offline or a synchronous system, the communication of RS232 must be considered while doing the wiring. Because RS232 is short in commu-nication distance, RS232 interface should be prepared at the bottom of screen (or bot-tom of supporting columns) while doing the wiring, in order that personnel can con-nect the screen to laptop.

3 Chapter III: 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. 1. Select Tool\Backup LDU date\Save to computer 2. Select a location for saving backup file and name the file to be saved. 3. 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 mainboard inside LDU. Change for a new LDU mainboard, and connect it to power supply, communication cables and optic fiber. 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 Fiber and Optical Fiber Plug Optical Fiber should be multimode.

• For outdoor use, the optical fiber is usually fusion spliced by expertise on-site and does not need to change.

• For indoor use, optical fiber is usually grafted in the optical fiber connector. So you need to be careful when inserting or unplugging the optical fiber head, not to damage it.

• Please take the following steps to unplug the optical fiber:
