I realize NCT5104D is configurable.
The customer has seen the board and wants to use com1 to connect the 5v modbus "proprietary RS485" to it.
I am having significant difficulties explaining to them why using com1 is a really bad idea.
This is not a deliverable at this point in time but comming soon.
I have other deliverables before this one.
Can someone give me a how to about the easiest way of creating a full ( = com1 5v capable) comX port?
