I am refitting a 1989 Kitamura with LinuxCNC using Mesa 7I93 and 7I77 cards. I am confused as to connecting up the various servos. Right now I am trying to connect the Spindle servo amp(Sanyo Denki 20BA15offwb4) through the DA converter (SDC-203). The original control received 7 wires form the DA converter to 2 seperate cables. Where do I connect the SDC-203 lines to the 7i77? I have attached wiring diagrams of the parts in question. Thanks for your help.
