Enshu S-400 programming problem

Hello all,

this is my first post. I've just found this website looking on google. It's a great website.

I've a problem on a Enshu S-400 Enac CNC machine with Jaskawa JZNC-IRK31M-131J00 control. I need to reprogram this machine but I don't know how to set the circular switch on the FC200 board to allow the reprogramming from the FC903 board by RS232 interface.

Therefore the questions are:

1) Could anybody explain to me the different circular switch positions on the FC200 board ? Which is the correct position to allow reprogramming ? I'm unable to find a manual on the web.

2) Since it's my first time ever that I have to reprogram a CNC machine, could anybody explain to me how to do it (at least the main passages) ? I will use Cimco Edit 8 with the original CNC programs.

3) Which is the pin diagram for the RS232 interface for the file transfer between the CNC and the computer ?

I've attached some photos. Don't look the japanese write, now it's in english.
