The GE ARCNET No-LAN LM Gas Turbine Control Board DS200PANAH2 features one 40-pin connector, 10 jumpers, and one 64-pin connector. The GE ARCNET No-LAN LM Gas Turbine Control Board DS200PANAH2 also has two RF FETs to amplify and adjust the signal. The RF FET components have turn screws you can use to adjust the signal. When the drive is removed from the power source, you can use a screwdriver inserted into the RF FET transistors to make adjustments. When the electrical power is restored you can test the board and determine if further adjustments are called for.
The connectors on the board are connected to ribbon cables and due to the fragile construction of ribbon cables, guidelines must be followed to prevent damage to the cables. The ribbon cables are used to carry signals to the board for processing and also carry signals transmitted from the board. When you remove one of the ribbon cables from a connector on the board, never pull it from the ribbon because it might pull the cables out of the connector. Instead, hold the connector portion in one hand and pull it out from the cable. With your other hand hold the board down to protect it from bowing under the stress of the cable being removed. To install it line it up with the connector on the board and press it into the connector. Firmly press it into the connector and visually inspect it to see if it is seated in the connector.
