1Builtin Cable Equilizer, Reclocker circuit and Cable Driver, support for maximum Cable length (for Belden1694A). 2SDI line input and output distance: SD supports 400m, HD supports 200m, 3G supports 100m (theoretical value, the specific distance is related to the cable quality). 3Builtin wide voltage design, support DC5V36V voltage input (power maximum 2W), more suitable for engineering use. 42 SDI signals are output at the same time, without any setting. 5The pure hardware processing plug and play, but also can automatically detect different SDI signals, when the input of effective SDI signal, LED indicator will show green, if there is no signal or signal noncharacter and standard LED indicator will be extinguished, so that engineering customers more easily judge the problem.
