The IS200GFOIH1B is described as a Ground Fiber Optic Board. This model was made by General Electric as part of the Mark VI IS200 series and can be used in systems related to the Mark VI IS200 series.
The IS200GFOIH1B includes a field programmable gate array chip from Xilinx (Spartan XC2S50E.) This chip has a flexible, regular, programmable architecture of CLBs (configurable logic blocks.) It amount of RAM available on this model is 32K. There are four transformers, located in a single line toward the front edge of the board, which also includes nine test points and one pushbutton switch component placed in the front quadrant of the board. The board has several resistor network arrays, along with resistors, capacitors, and diodes.
The IS200GFOIH1B has a single backplane connector as well as a small vertical pin connector (P6.) The board also has a connector to accept an optional auxiliary board. When this board is installed, four screw connections threaded through factory-made screw mounts on both boards keep it in place.
More information on the IS200GFOIH1B, its function, installation, components, auxiliary board, and handling instructions can be found through resource publications made available by the manufacturer, such as user guides, data sheets, and manuals. Unfortunately, information on the GFOI model is limited and difficult to find since General Electric has discontinued the model; all of the above information was taken from a visual inspection of the unit.
