3: Hardware

This section describes the hardware components associated with the Phoenix II system.

3.a. Keypad

The Phoenix II contains a built in 16-key keypad. With this keypad and the built in Liquid Crystal Display (LCD) you can

program and operate the Phoenix II. When the ALT key is held down while you are pressing another key, an alternate

set of keys is available to the user. The table below shows the alternate keys.

Note that if the ALT key is continuously held and the number key id pressed, again, the letter will scroll through the

following possibilities of letters:

ABCDEFGHIJKLMNOPQRSTUVWXYZ[]^abcdefghijklmno

pqrstuvwxyz{|}!”#$%&()*+,-./0123456789:;?@

For example, if you want the letter “W” you would hold down on “ALT” and then press the “7” key. Note that “V” appears

in the space, as Table 1 shows. While still holding the “ALT” key, press the “7” key again, and the letter “W” will appear.

Release the “ALT” key and the letter remains. You can also press the right and left arrow keys (while the ALT key is

down) to scroll through the alphabet.

The rest of the keys are explained below:

ENTER

Used as a means of indicating to the Phoenix II that an option is complete, and ready to be

acted upon.

CLEAR

Used as means of backing up one question in a menu.

SPACE

When not at the main menu, the SPACE key inserts a space at the current location of the

command line and will also allow scrolling through options in ascending order.



This key allows viewing/selection of options in a descending order. Also used as a non-

destructive backspace key when entering a line of data.



This key allows viewing selection of options in an ascending order. Also used as a non-

destructive key to move one position to the right when entering a line of data.

ALT

Used only in conjunction with other keys; ALT allows existing keys to perform alternate

functions. Use of the ALT key is similar to a SHIFT key on a keyboard, in that the ALT key

must be pressed and held for the duration of the associated key press.
