I am trying to fix a broken programming cable for a Modicon Momentum PLC and would like to know the Pinout for RS232. The PLC has a RJ45 connector and a 9 pin Dsub is on the computer end.

 

The cutsheet for the Niobrara MM1 cable shows the pinout for the RS232 Momentum port. "http://www.niobrara.com/pdf/MM1.PDF":http://www.niobrara.com/pdf/MM1.PDF
