To help you figure out what you need, we have made a generic list of
important issues. These are guidelines only, so you should communicate
the application to your supplier to ensure a optimal choice.
1. Define reading
distance and sectors
2.
Installation outdoors or indoors
3. Interface
type; What equipment should it connect to?
Size:
Size matters - at least for the viewing of displays. As a quick
approach, we have listed some distances between viewer and display with
corresponding recommended minimum size.

Light emitting characters
appears larger, but often possess a strong directivity for outdoor signs
(e.g. LEDs). The LCD range of outdoor scoreboards have an impressive
viewing cone. Light emittance will generally increase reading distance.
Environment:
Select an outdoor model for polluted or wet places. Food industry
requires regular hose-down of all equipment. Indoor models are intended
for well protected and clean office-like environments.
Interface:
Normally, some external equipment will generate some sort of signal to
be interpreted by the scoreboard. Determine the interface specifics;
Analog (e.g. 4..20 mA, 0-10 Volt) or serial data, parallel data, pulsed
(frequency or pulse-width), counter. You need to know the signalling to
be able to choose the right product.
