UC400ETH with UCBB

[Erphillips]

I know the UCBB is not the ideal board to use with the 2nd port of the UC400ETH as the Input / Output on pins 2 thru 9 are configured opposite on the UCBB, but that's what I have in hand to use right now, In my case I'm good with losing the pin 2 thru 9 function entirely, the extra 4 Inputs and extra 4 outputs still useable as configured will fully satisfy my needs and allow me to use the parts I have in hand now.

My actual question is can I plug the Port 2 from the UC400ETH directly into the UCBB board CN2 and just not configure any of the Port 2 Pins 2 thru 9 in any way, Or do I need to physically isolate the pins 2 thru 9 between the boards so there is no electrical connection on those pins? Isolating the pins is easy enough but clean and simple if I can just plug in the cable and ignore the pins in configuration


Thank You

Hi Ed,

Yes, you can plug it directly, it will not hurt the UC400ETH, but those pins 2 to 9. will not work on the input type port.

Good Deal, I had expected it would be okay to plug it in and just use the limited pinout.

Thank You
