DFPS Base and Service Board (A3043)[02-MAY-22] The Direct Fiber Positioning System (DFPS) Base and Service Board (A3043) consists of two square circuit boards connected by three flex cables. One square is the base board upon which we mount fiber positioners. It is 3.2 mm thick with counter-bored holes to accommodate the positioner bases and two mounting screws that fasten the base board to the base plate. The other square is the service board into which we plug one DFPS Controller Board (A3045A) per fiber positioner on the base board. The service board plugs into the bottom side of the DFPS Backplane Board (A3044A).
The base and service boards are roughly 19 mm square to fit inside a 20-mm square envelope. The bottom side of the service board will provide connectors as shown below.The sixteen connectors each mate with a twelve-way female connector on a controller board.
