Cable for fx48er

4 posts in this topic

Hello world I've been given an old MELSEC FX-48ER, but to use it I need an interface cable. Can anyone give me the connection diagram for RS232 comms? Thanks JeffK

From memory I don't think that the FX-48ER supports RS232 directly. If I remember rightly the programming lead is a RS422-RS232 convertor but i'm not sure as it's a while since I used the Mitsi.

FX-48ER is an extention unit and it cannot be programmed. You need a base unit, for example FX-48MR that is connected to your unit. Than you need a cable with RS232 to RS422 converter to program it.

As the other have said, you have an extention unit, not a programmable PLC (There is no cpu in the extention units) if you manage to get the main unit, the cable you need is the SC-09
