You don't tell me that I simply cannot read a simple text file when ....

* I literally have the supplied programs and files from the archives

* Have access to the script that is for programing two Duometric LVX devices

* Mapped out in personal documentation how a picking system receives input from the Duometric LVX devices

* Am able to correctly flag half the Duometric LI264 light barriers by checking said documented input

But sure, tell me that the issue is still something in software and not in hardware and make me reprogram the LVX's, and also swap inputs of both LVX's just to see the same light barrier issues.

I'm clearly some bumbling incompetent fool.
