SCD5510X's constructed high speed CMOS process, consequently high speed noise SERIAL DATA, SERIAL DATA CLOCK, LOAD RESET lines cause incorrect data written into serial shift register. Adhere transmission line termination procedures when using fast line drivers long cables (>10 cm).

Optical Considerations 0.145" high character SCD5510X gives readability eight feet. Proper filter selection enhances readability over this distance. Using filters emphasizes contrast ratio between character background. This will increase discrimination different characters. only limitation cost. Take into consideration ambient lighting environment best cost/benefit ratio filters. Incandescent (with almost green) fluorescent (with almost red) lights have flat spectral response sunlight. Plastic band-pass filters inexpensive effective strengthen contrast ratios. SCD5580/2 red/high efficiency displays should matched with long wavelength pass filter range. SCD5583/4 should matched with yellowgreen band-pass filter that peaks displays multiple colors, neutral density grey filters offer best compromise. Additional contrast enhancement gained shading displays. Plastic band-pass filters with built-in louvers offer next step contrast improvement. Plastic filters improved further with anti-reflective coatings reduce glare. trade-off fuzzy characters. Mounting filters close display reduces this effect. Take care overheat plastic filter allowing proper flow.
Optimal filter enhancements gained using circular polarized, anti-reflective, band-pass filters. circular polarizing further enhances contrast reducing light that travels through filter reflects back display less than Several filter manufacturers supply quality filter materials.
