Thanks for your answers, The CPU/Conf card of the Option 11 just has one SDI port 0, I tried with a serial cable DB-9(female) to DB-9(female) that came with the old SS NTDU27 (Intel ISP1100) and I worked, this is the cable configuration pinout:
1 -- 7,8
2 -- 3
3 -- 2
4 -- 6,9
5 -- 5
6,9 -- 4
7,8 -- 1
