COMMAND SUMMARY
Table 10.6 alphabetically lists the serial port commands within a given access level. Much of the
information available from the serial port commands is also available via the front-panel
pushbuttons. The correspondence between the serial port commands and the front-panel
pushbuttons is also given in Table 10.6. See Section 11: Front-Panel Interface for more infor-
mation on the front-panel pushbuttons.
The serial port commands at the different access levels offer varying levels of control:
• The Access Level 1 commands primarily allow the user to look at information only
(settings, metering, etc.), not change it.
• The Access Level B commands primarily allow the user to operate output contacts or
change the active setting group.
• The Access Level 2 commands primarily allow the user to change relay settings.
Again, a higher access level can access the serial port commands in a lower access level. The
commands are shown in upper-case letters, but they can also be entered with lower-case letters.
