SOFTWARE
Crimson software is available as a no charge download from Red
Lion’s website. The latest version of the software is always available from
the website, and updating your copy is free.
DISPLAY
This operator interface uses a liquid crystal display (LCD) for
displaying text and graphics. The display utilizes an LED backlight for
lighting the display. The backlight can be dimmed for low light conditions.
The LED backlight has a limited lifetime. Backlight lifetime is based
upon the amount of time the display is turned on at full intensity. Turning
the backlight off when the display is not in use can extend the lifetime of
your backlight. This can be accomplished through the Crimson software
when configuring your unit.
