Function: 1: SDI Splitter Please connect the device according to the steps at first. This SDI splitter support SD-SDI(270Mbps), HD-SDI(1.485Gbps) and full HD 3G-SDI(2.97Gbps) video format. 2: Extend function This product has the function of build-in Equilizer,Reclocker and Cable Driver, support max cable length(Belden-1694A) as below: SD-SDI support 300m,HD-SDI support 200m, 3G SDI support 100m(It is a theoretical value,the real instance have something to do with the cable quality). 3: Intelligent design: Plug and play.And it can detect the different SDI signal automatically,the LED will became green when it detect the valid SDI signal input, otherwise,the LED would not light. 4. It is a SDI (Serial Digital Interface) signal splitter, which can convert the signal from one SDI port to 4 SDI ports, and supports the input and output of full HD SDI signals, easy to use, high stability and reliability. It is widely used in all TV stations and other workplaces, security monitoring, training places and so on. 5. Operation: 4 SDl signal output at the same time and do not need any other settings. The main unit can detect the different SDI signal,the LED will become green when the SDI signal is valid.
