5. Operation

This chapter describes the alarm types and status for the
PRISM 4151.

Interface Start-up

Once a compatible terminal is properly connected to the
unit, you can start a terminal interface session by sending a
BREAK command to the unit (or by pressing <return> four
times). If a password has been previously establish, you
must enter the correct password to continue the session. The
password is case-sensitive.
If you have forgotten your pass-
word, note the date and time shown on your screen and con-
tact TxPORT Technical Support. You can establish a
password through the Utilities screen on page 3-10.

Once a valid password has been entered, the Main Menu
screen is displayed. If you are unfamiliar with the PRISM
4151 interface, commands, and menu structure, refer to
Appendix A, Terminal Interface, for specific information
concerning the menu structure and operator commands.

If you do not enter a keystroke for
10 minutes, the terminal interface

automatically logs off.
