SU751 can accomodate 5 small sub-modules (here numbered from 1 to 5), each connected thorugh 3 I/Os to the SU751 connector and so to the FPGA.

Note: 1) INJ<1..5> can be jumpered on SU751 to INP<1..5> in order to be fullly compatible to SU704. Normally not necessary. 2)The additional GND pins can be connector in the FPGA as outputs driving 0. Be carefull not to drive 1! 3) The LEDs are active low, like in SU704.
