4.2.1 LCD Front Panel 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 two distinct
areas showing current information. The upper area shows the current parameter being monitored,
such as 'Frequency' or 'Data 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.

4.2.2 Cursor Control Arrow Keys

A set of 'Arrow' or 'Cursor' keys (↑), (↓), (→), (←), is used to navigate the parameter currently
being monitored or controlled. Table 4-2 describes the functions available at the Front Panel.
4.2.3 Numeric Keypad
A 10-Key Numeric Keypad with two additional keys for the 'Enter' and 'Clear' function allows
the entry of data into the system. Table 4-2 describes the functions available at the Front Panel.
