I did not notice this post before replying. We are working on the same problem.
My email was rejected with the following message:
The following message to <firstname.lastname@example.org> was undeliverable.
The reason for the problem:
5.1.0 - Unknown address error 550-'No Such User Here'
Our customer has 3 of these machines. We have manually entered the regular params but cannot enter the option params. Have not done the diagnostics because without options, the control does not know the PMC, and diagnostics are for the PMC. We were told that param 922.7 is for enabling options, but could not turn that on either.
I have a password but no procedure for entering it; was never needed on the 0 series controls.
Let's work together to solve this problem.
