Troubleshooting:

1.The red light (PWR) is not bright or the brightness is low, Check whether the power adapter is normal 2.When TX green light (STA) is not on; Check the signal source; The green light stays on indicates regular work. 3.RX green light (STA) is not on, check whether the optical fiber module of the TX contacts normally; The green light (STA) is not on when there is no signal from the TX; Long light indicates that TX and RX work normally. 4.If there is no image on the display, check whether the display selects the correct channel input Specification: Technical Norms:SMPTE standard Video bit rate:MAX 3.2 GB/Second Interface:BNC Input/output cable specification:≤150m(Belden 1694A cable standard) Video input/output impedance:75Ω Video input/output voltage:1Vpp;Min:0.5Vpp/Max:1.5Vpp Differential gain (10% ~ 90% APL):<1% SDI resolution 625/25 PAL,525/29.97NTSC,525/23.98 NTSC 720P@50,720P@59.94,1080i@23/24/30/50/59.94,1080P@23.98/24/30/50/60 Support SDI specification 270Mbps(SD-SDI), 1.485Gbps/M(HD-SDI) SMPTE425M3Gb/s Mapping(3G-SDI) SMPTE424M 3Gb/s serial interface:(3G-SDI) Optical fiber interface:LC Fiber type:Single mode single fiber wavelength:Single mode 1310nm;1550nm Max transmission distance Default: 3KM;Max: 20KM Power:DC 5~12V/1A Power Consumption:MAX 5W Temperature:Operating temperature: -20℃ ~ +70℃ Humidity:Operating humidity: 0 ~ 90% Mean time between failures:≥100000hours Package: SDI extender TX x1pcs SDI extender RX x1pcs SFP 2 Pcs Power adapter x2pcs User manual x1 pcs
