PERATION
This section covers the programming and operation of ProScale Surface
Mount and Panel Mount LCD Displays Firmware* V2.1 and higher. If your
Display Firmware is prior to 2.1, or your Display is different than the Displays
described here, you must use the appropriate user manual for that Display.
* (F/W version is displayed on power-up or when ON/OFF key is pressed.)
The LCD
The above figure illustrates all the segments available on the Display.
Pressing and holding the
ON/OFF
and
MODE
key for 10 seconds
with
power off
will perform a full segment LCD test AND set all
programming parameters to factory defaults.
Programming
Several functions of the Display are user programmable. The following
describes what features are available and how to change the system’s
factory defaults to customize the Display for your application.
The keys pictured below have multiple functions. Timing, which is how long
a key is depressed, and the combination of the keys pressed is important.
This manual uses the term “
momentarily
” to describe a key press of
typically less than 1 second. Whereas
“press and hold
” is used to
imply a key press of typically longer than 1.5 seconds.
As an example: when using a computer keyboard to type a capital letter you
would “
press and hold
” the
SHIFT
key and “
momentarily”
depress the
appropriate
LETTER
key.
The “
function
” associated with key(s) pressed is executed on the key
RELEASE
, not the key
DEPRESS
. This is important since some keys
execute different functions based on how long they are depressed.
