In my panel, there are 3 sockets labelled S1, S2, and S3 on the right hand side of the main board. The S1 is connected to a RIO via a 4 pin Molex style lead. Does that help? Thanks Quote Link to post Share on other sites

Thanks The 4 pin headers just connect to the RS485 bus and power. 12v, 0v, A, B. Same as the screw terminals. Quote Link to post Share on other sites

Runs good still. Quote Link to post Share on other sites
