About the DS3800DDMA1A1A
The GE Div Multi Auxiliary Board DS3800DDMA1A1A features 20 single pin connectors and 7 trimmer resistors. It also is populated with terminals for attaching components, such as resistors or capacitors. The GE Div Multi Auxiliary Board DS3800DDMA1A1A serves as daughter card that adds capacity or functionality to another board in the drive. If you decide to replace the board, it is best practice to remove the GE Div Multi Auxiliary Board DS3800DDMA1A1A and the board to which it is connected.
The daughter card is populated with the functionality designed to bolster the processing and resources of the board it is connected to.
When you are ready to adjust the trimmer resistors, there are several considerations to keep in mind. The IDs assigned to the trimmer resistors are printed on the surface of the board. To adjust the trimmer resistors, use a tester device to gauge the signals produced by the circuit the trimmer is assigned to. When the signals are at the level you expect, you are finished adjusting the trimmer.
Other configuration settings are made to the board by moving the jumpers on the board. The board has 2 jumpers. The ID of 1 jumper is JP1 and the ID of the other jumper is JP2. The jumpers are 3-pin jumpers which describes the number of pins associated with the jumpers. You can insert the jumper over pins 1 and 2 or pins 2 and 3. The board will process differently depending on which pins are covered by the jumper.
