The program is still there, still working, no faults. Once I change the address I can go online and see the original program. And while it is not communicating the LCD still shows the static address as originally configured, and holds it after a reset. Just changing the static address wakes it up ...

And that is also true when connected directly with a single cable, that is until I changed the address, as mentioned. And yes, I tried different cables, it ...

The brand new ML1400 won't even respond to a ping or show up in an ARP table. Not exactly confidence building. The LCD shows ...
