In previous years, there were four input ports, also. However, I think two of them are "dummy" inputs. As in port 3 is the same as port 1 (same signals), and port 4 is the same as port 2 (same signals). Or maybe 1=4 and 2=3, not sure. Check the Programming Reference guide and the FRC2004 OI Reference Guide from IFI.
