I have two copies of UCCNC on different machines - 2111 (existing0 and 2113 (which I am currently installing/configuring). I am confused about the labelling of Port 1 O15 on screen on 2113 as it is marked as "output" but Port 1 I15 is an input on 2111. The manual says that this is an input. The 2113 LED shows as red when the input is active, not green.
Is this just an screen display error, or have I misunderstood something?
Thanks,
