UTP Transceiver一.PRODUCT OverviewReceiving and transmitting video signals over UTP cable. The UPT transceiver transmitter convert the video signals into differential signals by he UTP cable, and then the receiver converter thedifferential signals into video signals. Having excellent performance of common mode interference suppression so that is can transfer clear image signals in strong interference environmentThis product widely used in the fields of security, campus, and logistics etc. which need transmitter the high-definition AV signals. Also this product can transmit the baseband video signal including the color and PAL, NTSC, SECAM. There are many advantages for it, such as strong anti-interference, long distance transmission, and low price etc.二.PRODUCT CHARACTERISTICS:1. Long-distance transmission, high display image quality. Using advanced processing technology for the video signal amplitude and attenuation of different frequencies so that can maintain the original vieo sigal clearing and real-time, Almost no distortion even if thelong-distance transmission.2. Wiring convenient, high utilization of the UTP cable. chere are four groups of pairs in one Category 5 cabling, a pair of wires is used to transmit video signal, other pair can transmit audio signal data, power supply etc, which can ehance the cable utilization, when avoid trouble wiring, reducing the project cost.3. Strong anti-interference. UPT transceiver can restrain common-mode noises in the strong interference environment.4. Easy to use. Use the UTP transmitter the video signals, thefront-end access to special transmitters, control terminals access to specific receivers, this equipment price is very cheap, easy to use. Once installed, Long-term working stability, d on’t need high professional to control.5. AC/DC 12V-24V power supply, transient suppression protection function三.Status indication and settings1. Passive Video UTP transceiver is without LED indicator, will work as long as the polarize of terminal block connect the UTP cable.2. Active Video UTP transceiver is with Power LE D and Video Input LED, Power LED light as long as the power insert. Video Input LED light as long as the video signal input. Multichannel transceiver use RJ45 as the connector, please split line following the wiring diagram. Active Video UTP transceiver is provided with video adjusts function. The transmitter have distance gain adjustment, the receiver adjust the video brightness and sharpness. The way of setting as follow:NOTE:1.Monitor shows no signal:Please check whether the power supply to the equipment is normal, whether every connector connects well, and whether corresponding indicating lights are on. First, connect the output video signal to the monitor directly (or DVR), to check whether the output image is in normal condition. When the image output is normal, connect the equipment according to the manual. Then check whether the power is connected, whether the twisted wire has connecting problems or disconnects, and whether the modular plug is connected according to the wire map. The quality of twisted wire is also important. You can also replace thetransceiver with another one to verify whether the previous one has qualitydefects.2.High-frequency cross grains or wide cross-lines of black and white interfere withimages:Please check whether there is electric leakage in active video cameras, active monitors and active DVRs; if there is, ground potential balance will be caused.Please disconnect the earth lead in the front of the video camera so that only the earth lead of the DVR works. For multi-channel transceivers, if there is electric leakage at one channel, the other channels will be interfered with, so pleaseremove the channel with electric leakage. A power adapter of poor quality will also cause 50Hz electric leakage, please replace it with a AC transformer.3.Images are dim or even turns black and white and with spots:Weak Signals can cause this problem. Please adjust the DIP switch and thepotentiometer of the receiver to strengthen the signals. If you are using passive transmission, please change to active transmission. Poor-quality twisted wire will also make the signals weak.4.Images distort and roll:Please check the RJ45 on either end of the twisted wire to verify whether the order of line pairs in them is correct; if it is not, please correct the order; orcheck whether the signal polarity of the binding post at either end is correct, if it is not, please adjust the signal polarity. The orderof the line pair for RJ45 is 1/2, 3/6, 4/5, and 7/8.5.Some images have a luminous edge and white ghosting:Too strong signals can cause this problem. Please adjust the DIP switch and the potentiometer to reduce the signal strength appropriately; or according to the advised distance on this manual, customers can choose anyone of the working modes of Passive+Passive or Passive +Active or Active +Active to adapt to different environments.6.Part of video image signals transmitted in one twisted wire does not show wellwith Active Multi-channel TransceiverToo wide strength gap of different signals can cause this problem. Please note that the distance between the transmitter and the video SYV should not exceed100 meters, or adjust the transmission mode to Passive+ Active according to the actual installation distance. Please also check the quality of the twisted wire by replacing a good pair to a defective channel.。
