3.0 Operating Procedures
Operation of the DMD2401 LB/ST consists of controlling the unit operating parameters and monitoring
status and responses via front panel or Terminal Mode control.
These methods may be used separately or together to monitor and control the DMD2401 LB/ST.
3.1 Front Panel Control
The front panel of the DMD2401 allows complete monitor and control of all modem parameters and
functions via a keypad, LCD display and status LEDs.
3.1.1
Front Panel Layout and Features
The front panel layout is shown in Figure 3–1, showing the location and labeling of the front panel. The
front panel is divided into three functional areas: the LCD display, the Keypad and the LED Indicators,
each described below.
3.1.2
Front Panel LCD Display
The front panel display is a 2 line by 16 character LCD display. The display is lighted and the brightness
can be set to increase when the front panel is currently in use. The LCD display automatically dims after
a period of inactivity. The display has three distinct areas showing current information. The upper left
shows the current area of use, either Mod, Demod, Modem or Test. The upper right shows the current
parameter being monitored, such as ‘Freq.’ (frequency) or ‘Bit Rate.’ The lower line shows the current
value of that parameter. The LCD display is a single entry window into the large matrix of parameters
that can be monitored and set from the front panel.
The backlight brightness can be set for two states: Active and Idle. The active state is entered whenever
a key on the front panel is depressed, while the idle state occurs after approximately 45 seconds of
inactivity. Each state may be set to ‘Off’, 1/3 brightness, 2/3 brightness and full brightness. The default
setting is full in the active state and 1/3 in the idle state. To change the settings for either state, go to the
‘Modem LCD Active’ or ‘Modem LCD Idle’ brightness parameter and adjust to the desired values.
3.1.3
Front Panel Keypad
The front panel keypad consists of two areas: a 10-key numeric entry with 2 additional keys for the
‘Enter’ and ‘Clear’ function. The second area is a set of ‘Arrow’ or ‘Cursor’ keys (

to navigate the parameter currently being monitored or controlled. During entry, the cursor keys allow
moving a cursor to individual digits of a numerical entry or scrolling through the available options of a
selection entry.
