ME228DX IP Mux and modulation module is the latest generation Mux-modulating all-in-one device. Its modular design with each daughter card containing 8 multiplexing modules and 8 ATSC-T modulating modules makes each daughter card able to work standalone and receive the UDP format TS through GE port. It can support up to 256 different IP address or port number and output adjacent channel carrier (40M~960M) through the two RF output interfaces. Additionally, 1U chassis supports up to 3 cards (24 channels mux-modulation).

This ME228DX IP Mux and modulation module has adopted slot structure to allow maximum 3 ME228DX cards to insert one device simultaneously. To draw a conclusion, its excellent integrated level, powerful.
