3.4.10 Key Level
Each command in the GMW-25 Generator repertoire is assigned to
one of two
key levels . Most commands are at key level A. This
means that they are enabled by default on power-up of the GMW-25
Generator.
The remaining GMW-25 Generator commands are at key level B.
These commands are for serious hardware and software debugging,
and for factory test or setup of the GMW-25 Generator. Level B
commands do not appear in the Operation Manual for this generator.
Level B access is not granted to customers, but is only for MKS, ENI
Products personnel. This is because level B commands have the
potential for damaging the GMW-25 Generator (not to mention the
user's equipment or process). The help screens reflect the commands
that are available with the present level of security.
In this document, the key level of each command is identified as either
0, A, or B. If you attempt to enter a command at an unauthorized
access level, the system responds with:
*ACCESS DENIED
