3.1
USER INTERFACE
RPM4-AD is designed to offer a balance between simple, straight forward operation and the availability of
a wide variety of advanced functions with a high level of operator discretion. The local operator interface
is through a 2 x 20 character alphanumeric display, a function/data keypad, a cursor control pad and a
Ready/Not Ready
indicator.
Remote communications are by RS232 (COM1) and IEEE-488. See Section 4 for information on remote
communication.
3.1.1
MAIN RUN SCREEN
The RPM4-AD MAIN RUN screen is its home display that is reached on power-up and from
which other functions and menus are accessed. It is the very top level of all menu structures.
The MAIN RUN screen is where RPM4-AD is left in normal operation. It displays the current
measured pressure, altitude and/or airspeed as well as a variety of additional information if
desired.
Figure 3 and its legend summarize the RPM4-AD MAIN RUN screen fields and their functions.
RPM4-AD has a screen saver function which causes the display to dim if no key is pressed for
10 minutes. Pressing a key restores full power to the display. The screen saver time can be
changed or screen saving can be completely suppressed (see Section 3.5.5.1).
