DS200UDSAG1A Operation

The board receives and sends signals from other boards as well as a 40-pin connector that is used to populate the board. Other boards and gadgets in the drive typically send signals to the board.

The signals are processed by the microprocessor on the board, which employs the other components on the board to do so.

The 4-character screens and the 32 LEDs that populate the board offer information to the operator about the state of the board. When the signals have been processed, the new information is transferred to additional components and boards. It's crucial that all of the signals connect to the 40-pin connector.

The ribbon cable, on the other hand, is easily damaged due to the lack of support provided to the plastic connector on the ribbon cable's end. That is, removing the thin copper wires from the connector is simple. Never pull the ribbon cable out of the connector on the board to keep it intact. Instead, firmly hold the ribbon cable's plastic connector and slowly pull it out of the connector.
