If you try to use a function that is not accessible from the guest login, you will see a message such as
“Access denied” or “Command canceled”.
Logging Out
You can log out using the following commands:
logout
logoff
exit
quit
Changing Username and Password
To change the user name and password, use the following commands:
• “F100 P – Change User Password” on page 90
• “F100 PN – Change User Name” on page 91
To reset a lost or forgotten operator username/password, use F100 P and F100 PN commands from the
command line interface on the serial port.
Session Timeout and Priority
The XL-GPS’s system firmware has session timers that will terminate an inactive command line session
on the network port after 15 minutes. The XL-GPS does not terminate inactive command line sessions
on the serial port.
The user can open a network port session and a serial ports session concurrently, provided the other
session is inactive (i.e., not actively performing a function such as
F8 – Continuous Time Once-per-
Second ). The XL-GPS does not allow two or more concurrent network port sessions.
A network port session can be used while a serial port session is open. However, if the serial port
session receives user input at this point, it takes control away from the network port and does not yield
control to the network port again. The network port will show a prompt, but will not accept additional
commands after the serial port has taken control back. At this point, closing the network port connection
and opening a new one will also fail; a network port connection cannot be re-established until the serial
port has been closed. The following transcripts show the results of a ‘contest’ between a serial and a
network port session:
Serial port session:
