Modicon Gould J470

I am using an old modicon SC684 PLC.

The J470 I/F offers 1 serial Rs232 port to access the PLC.
However the J470 I/F has another port, called P180. In the ancient days this port was used to connect a programming device.

I want to use this P180 port to access the PLC besides the Rs232 port. Who can tell me what kind of port the P180 is?
Is this a RS422 port? How to use this and what is the pin layout?
