2 Setting up the kit

The kit should be unpacked in a static-free environment, with adequate anti-static precautions being observed.

The cables are all keyed and only one cable from the kit will fit each of the connection steps described below:

1) Connect the display to the driver card, using the 33 way FFC cable. You will notice that one end is only 32 ways wide; this end plugs into CN400 on the driver card.

2) Connect the OSD board to CN500 on the driver card.

3) Check the jumper settings on the driver card and confirm that they are correctly set according to the display requirements.

4) Connect the 12V output of the DC-DC converter to connector CN300 of the driver card.

5) Connect the DC plug on LED backlighting cable protruding from the display panel to the socket attached to the thinner set of cables from the 24V input of the DC-DC converter.

6) Plug the 24V power supply to the thicker set of cables attached to the 24V input on the DC-DC converter.

7) Supply a VGA source via CN2 (Analogue RGB) or CN1 (DVI).

8) The system will power up automatically, however the correct input will have to be selected from the OSD menu. Refer to the driver card specifications for the OSD menu functionality.
