Need help to understand Dsub fabrication. The unit came with a tray and the transponder. The only parts for install are some male and female pins. The G3xtouch install manual only refers to GSU25 interface . There is no 45R section with material list for connectors or pictures of assembly parts. I am not a digital/Dsub veteran, so can you point me in the right direction ? Perhaps Stein did not include everything, but I need to know what I need to discuss it.
