Mechanical information

Figure B-1 shows the dimensions for the connectors on the top side of the board. See 
Table B-1 on page B-4 for details on connector type, part numbers, and manufacturers. 

Figure B-1 Board dimensions (top view)

The Integrator/IM-AD1 is designed to be stackable (as the top card). Figure B-2 on 
page B-3 shows the dimensions for the connectors on the bottom side of the board as 
viewed from the top side of the board. These connectors carry the signals between the 
IM-AD1 and the logic module. (All dimensions are in mm.)
