Description
The 10-1858, LED Interface Board #1 (Exhibit 4) provides the interface point between the Graphic Controller Card and the LEDs. Each Graphic Card must have an LED Interface Board #1 for connection of the first set of 128 LEDs. The board is factory mounted to the backside of the graphic panel door assembly. The LEDs are factory installed and connected to the board’s 8-position terminal blocks (32 total) as required to suit the layout of the custom graphic display. A 34-pin ribbon cable 10-1950 is used to connect terminal P1 on LED Interface Board No. 1 to terminal P6 on the Graphic Controller Card.
