1. Description
This 3G SDI TX/RX BOX are fiber optic serial digital video transmission units that offer the industry's broadest range of digital rates 3Gbps bandwidth while maintaining the signal quality that broadcasters demand.
The transmitter unit accept uncompressed 3G/HD SDI signal, and convert it to ST Fiber.
The receiver unit reconverts the uncompressed ST fiber signal back to BNC and HDMI output in the same time.
The transmitter and receiver modules include LED indicators to display Power On, SDI signal presence and optical fiber presence. The units use DC-5V power supply

DC-5V Power Adapter*1
5. Installation
Connect the provided AC or DC power supplies to the power socket of the transmitter and receiver
Connect SDI cable between the SDI video source and the transmitter BNC input
Connect SDI cable between the receiver BNC output and the SDI video monitor or SDI DVR
Connect ST fiber between the transmitter and the receiver ST Receptacle
6. Notes
A. No video output and some one of the three LEDs not lighted
Please check the power supply if work
please check the video source if work
please check the coaxial cable BNCs if all tightened well
please check the ST fiber if inserted well
B. There is video display, but video flash
please check the video source format if right
please check the coaxial cable BNCs if all tightened well
please check the ST fiber if inserted well
this issue happens often when the ST end face is dirty
For long range application, please check the fiber transfer link-budget, if it is too long, the received optical signal is very weak, and may be out of receiver reclocker capacity and fail to recover the useful signals
