DS200KLDCG1AAA GE密钥/LED/显示板

The GE Key/LED/Display Board DS200KLDCG1AAA features 32 LEDs, twenty-one  4-character displays, and one jumper.   The GE Key/LED/Display Board DS200KLDCG1AAA also features one 40-pin connection strip on the rear of the board.   The jumper on the board is used to modify its behavior by changing the position of the jumper over the pins. For example, if the jumper covers pins 1 and 2 you can move the jumper to cover pins 2 and 3.   The documentation that came with the original board describes the jumper and how moving the jumper changes the behavior of the board.

However, some jumpers are for use by the factory only and are not to be moved by servicers. In that case, the jumper is used for testing during manufacturing and the operation of the board with the jumper in the alternate position is not supported. Refer to the information supplied with the board for more information.

The board is attached to the drive cabinet with screws inserted in the four holes in each corner. The holes align with the screw holes in the cabinet rack in the drive. Before you remove the defective board, note where the board is installed and also how cables are routed in the cabinet. Cable routing is important because it protects the drive from interference caused by high-voltage current if a signal cable is too close to a high-voltage cable. Also cable routing helps maintain proper air flow. Improper cable routing might block air flow and cause components to heat up.
