I have an old R-J3iB that I want to configure the UOP signals with the digital Outputs. I have the digital outputs assigned to Rack 1 Slot 3 Start 1, but when i try to assign the UOP outputs to this I get "Port Assignment is invalid."
I have done this before using R_J3 on other Cells and this has always worked fine. Is there something different I need to be doing for this type?
Thanks in advance
