The GE DOS DUP Processor Board DS200DMCBG1AKG contains three 26-pin connectors, one 40-pin connector, and 19 jumpers. The board also has 2 LEDs. The jumpers on the DS200DMCBG1AKG can be used by the installer to change the behavior of the board. The manual that ships with the original board from the factory describes the jumpers and how they change the behavior of the board. However, not all the jumpers can be moved by the installer or servicer. Some are for use by the factory only. They are used for testing purposes only at the factory. The manual that comes with the original board will also identify those jumpers.
Be aware that when you are replacing the board you only have to move the jumpers to match the positions of the jumpers on the old board. You might find when you inspect the board side by side that the jumpers on the replacement board are in different locations because of design updates. It is best practice to identify a jumper on the old board by the identifier printed on the board. An identifier for a jumper might be JP1, JP2, or JP3. LEDs are identified as CR2 and CR12. Find the same jumper on the replacement board and make sure it covers the same pins.
Even if the locations of the components is different, the replacement board provides identical processing functionality. This is due to the testing performed on the replacement board to ensure it maintains compatibility.
