634 Serial and DFI NF4 Ultra-D

I can't get my 634 serial to work on my DFI NF4 Ultra-D. I have it connected to the internal com port on the motherboard. I can get it to turn on with both Crystal Control and LCD Smartie, but after the initial "Crytsalfontz" screen, it just displays a flashing cursor in the top left corner. Any help would be greatly appreciated.

The WR232Y08 is made for the CFA-633. It "fits" between the CFA-634 and the motherboard, but the pinout may or may not work. In your case, it looks like that is a "not" :( . What you probably need is something like this:


(see this thread https://forum.crystalfontz.com/showthread.php?threadid=4 for background information)

We have a new part that does this function, it is called a WR232Y23. Please write support(at}crystalfontz{dot)com (edit to '@' & '.') and we will see if we can get you one somehow.
