Front-Panel Keypad and Display
This section describes the Tempus LX front-panel user interface which consists of a graphic vacuum-
fluorescent display (VFD) and keypad. The keypad and display provide a convenient interface that
allows the user to quickly check the operation of the instrument and setup many control parameters.
If desired, the Network Administrator can disable the keypad EDIT key to prevent unauthorized tam-
pering with the instrument setup. Even when disabled, all status and control parameters are avail-
able for reading only.
Display Description
The display consists of a graphic 16 x 280 dot-matrix vacuum-fluorescent array. The VFD technology
offers very readable alphanumeric characters with variable font sizes. Time information is readable
at distances in excess of 15 feet. The keypad consists of an eight-key switch assembly designed to
allow easy parameter selection and control.
