Yaskawa SGDB-02VN with Mach3

Hello

I am trying to get an old Biesse rover 23 running with mach3 and Smoothstepper Ethernet 51 I/O Motion controller. Looking in the manual, I have found a "connection and wiring" for Mitsubishi and I thought I could use this but with smoothstepper instead using pin an dir..

I am stuck with the pinout from the SGDB-CANV, I can not find any manual, after days of looking, wich pins are what in the 13 pins jacket labaled 1CN.

Any ideas?

SGDB-xxxN are early Mechatrolink-I drives. the bus gets connected to the blue 8-pin honda connector at the top left. 1CN circled in red is for limit switches and the like.
the manual is available on the web, google for SIE-S800-26.4B. i doubt about mach3/SS...
