Product Overview
NDS3542 series products are DEXIN’s all-in-one devices which integrate Demodulation, trans-mux and modulation (DVB-C, DVB-T, ISDB-T or ATSC) to convert satellite signals into digital RF output. Its pluggable structure design greatly facilitates the change of modules (RF/HDMI/CVBS/SDI/YPbPr/…) as needed. The unit in this sheet is a 1-U case which supports 4 DVB-S/S2 RF inputs with 4 CAMs accompanied. The CAM requires NO unsightly external power cords, cables, or additional remote control device.
To meet customers’ various requirements, NDS3542 is also equipped with 1 ASI input, and output with 2 ASI ports and 1 UDP IP port.
The output modulated signals are to be received by TVs, STB and etc with corresponding standard.
