Error Message

sc_usc.cfg is missing InvertOptoOut entry - maybe corrupted?

Cause

The sc_usc.cfg file located in the <SCAPS>\system folder is not readable or corrupted. It is checked when the USC Server is started. This message is shown if the first line of the .cfg file does not start with "InvertOptoOut".

Solution

Check if the sc_usc.cfg file located in the <SCAPS>\system folder is ok. If in doubt you can delete this file from the system folder such that a new file with default values will be generated with the next start of the USC server.
If you have a backup of this file stored somewhere, it might help to restore this backup.
