As decided during the Electronics Preliminary Design Review, december 1998, the Local Station electronics for the EA will be modular. In this note, we define the integration of all the electronic boards and the definition of the local bus they have in common. This board, which is necessary for the software development and can be helpful for test on the site, will not be implemented in the field. The coordinates are in millimeters and indicate the position of the pin number 1 of each connector, with respect to 2 edges of the board. Connectors disposition for a 'Right' daughter board.
Figure shows the position of the daughter boards on the mother board.
Figure shows the side view of the electronic boards. There is no real reason for the Ethernet board to be inclosed in the metal box, together with the other boards, but we keep this possibility and as the FE prototype will have daughter boards, it will need some additional vertical space. Table shows all the signals on the local bus and the boards which must be connected to them. I FE TG Event Synchr. Local bus signals.
