EZ HMI Display Terminal
Technical Manual and Communication Functions Reference Manual
The EZ HMI (Human-Machine Interface) is a general
purpose display and input terminal designed with mi-
crocontroller applications in mind. Users can display
messages and data through its LCD display, and
get alphanumeric input from users with the use of
just a few simple commands. It even features a self
contained menu driven function that allows users to
set, edit, and save to its non volatile memory data-
herein referred to as Parameters, for later retrieval
and use by the user application programs.
A user interface function that carries these features
usually requires lengthy codes (it does). Now that
these functions are already built-in features of the
EZ HMI, there goes one detail you no longer need to
worry about- you can put all your programming effort
on the application project.

display module removed. You can use a VFD
display module in place of the LCD if you want
a high brightness- high contrast display.
