CHAPTER 4: INTERFACES
When entering a settings or command password via EnerVista or any serial interface, the user must enter the
corresponding connection password. If the connection is to the back of the B90, the remote password must be used. If the
connection is to the RS232 port of the front panel, the local password must be used.
There are two user security access levels, setting and command, for which you can set a password for each. Use of a
password for each level controls whether users can enter commands or change settings. Another option is to specify
setting and/or command access for individual user accounts.
• Setting — Allows the user to make any changes to any of the setting values:
– Changing any setting
– Test mode operation
• Command — Restricts the user from making any settings changes, but allows the user to perform the following
operations:
– Changing the state of virtual inputs
– Clearing the event records
– Clearing the oscillography records
– Changing the date and time
– Clearing the data logger
– Clearing the user-programmable pushbutton states
