RECEIVER-TRANSMITTER COMPLECT FOR AUDIO-VIDEO SIGNALS ON TWISTED PAIR WIRES. GE-42 TECHNICAL INFORMATION Is used to transmit signal from video camera with the UTP-5 cable on a distance up to 1200 m ( 1800 m when reinforced ) . Same complect is used to transmit audio or any other signal in a range from 10Hz up to 10MHz. · GE-42T TRANSMITTER. 1. Built in an internal cavity of coaxial tip BNC, 4 screw sockets are applied for having an input power and a symmetric output of video signal. 2. Power supply of the transmitter (built - in stabilizer) 3. Input signal 4. Output signal 5. Maximu output current 6. Minimal resistance of load 7. Frequency range 8. Step adjustment of high-frequency HF predistortions in a cable of communication on the 5 Mhz frequency 9. Protection against short circuit on an output 10. Range of working temperatures 11. Case · GE-42R Receiver. 1. Built in a plastic case with wall fastening 2. Screw sockets are applied for an entrance differential signal (it is necessary to observe polarity of its' connection), an input from the power supply 3. The jack is applied for output video signal 4. The light-emitting diode for indicating the process 5. Indemnification regulator of low-frequency osses in cable 6. Step adjustment of high-frequency HF predistortions in a cable of communication on the 5 Mhz frequency 7. Step adjustment of mid-frequency HF predistortions in a cable of communication on the 1,0 Mhz frequency 8. Current used 9. Input signal 10. Output signal 11. Maximu output current 12. Frequency range 13. Protection against short circuit on an input 14. Range of working temperatures 15. Case
