Programming F1-12MR-ES

Hello everyone,

Can someone help me with the pinouts of the programming port for a mitsubishi f1-12mr? I believe MEDOC can be used to program it, I just need to workout the interface cable for it. Does it talk 232 or 422?

Thanks in advance.

I did not work with F1-12MR, but we have a couple of F1-20MR series PLCs.
It reqires special interface unit F2-20GF1 that is plaged to PLC. This unit has RS-422 output. You plag your cable with converter 422->232 to this output.
