User Interface
The USR4204 offers two types of user interfaces: a Menu-Driven User Interface and a
Command-Line User Interface. Users and Administrators use the Menu-Driven User
Interface to manage the equipment connected to the USR4204. Administrators use the
Menu-Driven User Interface or the Command-Line User Interface to configure the USR4204.
Menu-Driven User Interface (a.k.a. “Menu Mode”)
The USR4204 Menu-Driven User Interface organizes commands into menus. See Figure 1
for a map of all menus. Each menu contains commands, text, and status where appropriate.
Menu commands listed on the following pages are shown within single quotes ('),
programmable names are shown within double quotes ("). A Menu command is a single
character that either performs an action or provides navigation to another menu. Menu
commands are not case-sensitive. Text can be any alphanumeric or non-alphanumeric
displayable characters.
Alphanumeric and non-alphanumeric characters include all ASCII characters
from 20h to 7Eh.
The USR4204 defaults to Menu Mode. To access the Menu-Driven User Interface, open a
terminal emulation window on a computer (using Courier or other fixed-width font) and
connect to the USR4204 remotely via modem or locally via the terminal port using a rolled
RJ45 cable. Hit Enter to show the Main Menu screen. If security is enabled, the login
prompt will appear instead.
Hit the spacebar or the Enter key to refresh any menu within the Menu-Driven
User Interface.
Command-Line User Interface (a.k.a. “Batch Mode”)
The USR4204 Command-Line User Interface allows an Administrator to configure the
USR4204 by entering commands individually or by sending a sequence of commands in a
batch configuration file. Commands are sent from a terminal as an ASCII data stream. A
Batch command is (with three exceptions) a string of two or three characters and an equal
sign (=) delimiter, followed by a parameter setting or text string, terminated with a carriage
return. Batch commands are not case-sensitive. Text can be any alphanumeric or non-
alphanumeric displayable characters.
The USR4204 will not parse multiple Batch commands in one line.
The USR4204 Command-Line User Interface can be accessed only by Administrators
(including Users that are granted Administrator privileges) to configure the USR4204. The
