NDS3542 series encoder modulator

NDS3542 series products are DEXIN’s all-in-one devices which integrate encoding, multiplexing and modulation to convert V/A signals into digital RF output. It adopts inner drawer-type structural design which greatly facilitates the change of encoding modules (HDMI/CVBS/SDI/YPbPr/…) as needed. To meet customers’ various requirements, NDS3542 is also optionally equipped with 1 ASI input for re-mux and 2 ASI out ports. MPTS and SPTS output are available via the gigabit DATA port.With its various inputs available, our NDS3542 series products are widely used in public places such as metro, market hall, theatre, hotels, resorts, and etc for advertising, monitoring, training and educating in company, schools, campuses, hospital…
