RS422 pinout

2 posts in this topic

Hi Folks,

I want to confirm the information of RS422 pinout of DB9 GT2308-VTBA and mini din 8p of FX3U-64M. I couldn't find any information inside the manuals and any other website. The attached files below are the only information that I have found on the internet and I'm not so sure.

The reason is I need to use TCC-120i serial repeater to connect RS422 with ethernet. Therefore, I need the pinout.
